Öğe Aperture fixation instead of transverse tunnels at the patella for medial patellofemoral ligament reconstruction(Springer, 2012) Hapa, Onur; Aksahin, Ertugrul; Ozden, Raif; Pepe, Murad; Yanat, Ahmet Nedim; Dogramaci, Yunus; Bozdag, ErgunMedial patellofemoral ligament (MPFL) reconstruction is an effective option for the treatment of recurrent patellar instability. Most techniques utilize the passage of a tendon graft through tunnels at the patella with the risk of patellar fracture. The purpose of this study was to investigate the strength of the recent MPFL reconstruction techniques (transverse tunnel, interference screw, anchor, and docking technique). Thirty-six saw bones were divided into four groups (transverse tunnel, interference screw, anchor fixation, and docking technique) with nine patellae in each. Patella-tendon constructs were pre-loaded to 10 N and cyclically loaded for 20 cycles from 2 to 30 N under load control at a rate of 5 N/sec. The construct was then tested to failure at a constant displacement rate of 6 mm/sec. Ultimate load (N), stiffness (N/mm), and failure mode were recorded for each specimen. The docking group had lower ultimate load [106 (SD 41) N] and stiffness [14 (SD 2) N/mm] values than the other groups tested (P = 0.007). The anchor group had lower stiffness [21 (SD 6) N/mm] values than the tunnel group [28 (SD 3) N/mm (P = 0.01)] and the interference screw group [31 (SD 6) N/mm, (P = 0.004)]. There was no significant difference in the ultimate load between anchor [299 (SD 116) N], tunnel [304 (SD 140) N], and interference screw groups [241 (SD 103) N] (n.s.). Aperture fixation techniques, especially interference screw fixation, were as strong as the technique utilizing tunnels in the patella for MPFL reconstruction.Öğe Axial plane coverage and torsion measurements in primary osteoarthritis of the hip with good frontal plane coverage and spherical femoral head(Springer, 2010) Hapa, Onur; Yuksel, Halil Yalcin; Muratli, Hasan Hilmi; Aksahin, Ertugrul; Gulcek, Serap; Celebi, Levent; Bicimoglu, AliIntroduction Mechanical factors play a role in pathogenesis of primary osteoarthritis of the hip. Torsion measures were made to detect whether there is a causal relationship between increase or decrease of femoral anteversion, acetabular anteversion, and osteoarthritis. There are no studies in the literature indicating a relationship between axial plane coverage and osteoarthritis of the hip. Deficient axial plane coverage of femoral head may also play a role in pathogenesis of osteoarthritis. Materials and methods Thirty patients with primary osteoarthritis of the hip and 29 control cases were included in the study. We used the method of Anda et al. (Acta Radio! Diagn 27:443-447, 1986; Comput Assist Tomogr 15:115-120, 1991) to measure axial plane anterior, posterior coverages in patients with primary osteoarthritis of the hip. The computerized tomography sections and pelvic radiographs indicated good frontal plane coverage and spherical femoral head. In addition to anterior acetabular sector angle, posterior acetabular sector angle, horizontal acetabular sector angles for axial plane coverage detection, femoral anteversion, acetabular anteversion, and McKibbin instability index were also measured. Results Posterior coverage was lower at osteoarthritic hips than the control group's hips (96.0 +/- 16.7, 104.2 +/- 10.6) (p < 0.05). Conclusion The results may indicate that in addition to other mechanical factors, axial plane coverage, especially the posterior coverage deficiency, may play a role in the pathogenesis of hip osteoarthritis.Öğe Biomechanical Analysis of Pullout Strengths of Rotator Cuff and Glenoid Anchors: 2011 Update(W B Saunders Co-Elsevier Inc, 2011) Barber, F. Alan; Herbert, Morley A.; Hapa, Onur; Rapley, Jay H.; Barber, Cameron A. K.; Bynum, James A.; Hrnack, Scott A.Purpose: To evaluate the biomechanical and design characteristics of newer suture anchors. Methods: Suture anchors were tested in fresh porcine metaphyseal cortex and cancellous troughs by use of an established protocol. A mechanical testing machine applied tensile loads parallel to the axis of insertion at 12.5 mm/s until failure, and mean anchor failure strengths were calculated. The mode of failure was recorded. Rotator cuff anchors tested included the Doubleplay and Opus SpeedScrew (ArthroCare Sports Medicine, Sunnyvale, CA); PEEK Intraline and PEEK Zip (Stryker, San Jose, CA); Paladin, SuperRevo FT, and CrossFT (ConMed Linvatec, Largo, FL); Piton (Tornier, Warsaw, IN); Ti Screw, ALLthread PEEK, LactoScrew, ALLthread Ti, and ALLthread PEEK knotless (Biomet Sports Medicine, Warsaw, IN). Glenoid anchors included the Gryphon BR P (DePuy-Mitek, Raynham, MA) and JuggerKnot 1.4 (Biomet Sports Medicine). Results: Mean cortical failure loads for cuff anchors were as follows: Doubleplay 5.0, 279 N; Doubleplay 6.5, 338 N; Opus SpeedScrew 5.5, 356 N; Opus SpeedScrew 6.5, 336 N; PEEK Intraline 5.5, 263 N; PEEK Intraline 6.5, 344 N; PEEK Zip 5.5, 435 N; PEEK Zip 6.5, 502 N; Paladin 5.0, 500 N; Paladin 6.5, 521 N; SuperRevo FT, 496 N; CrossFT, 569 N; Piton, 379 N; Ti Screw 5.0, 457 N; Ti Screw 6.5, 443 N; ALLthread PEEK 5.5, 476 N; LactoScrew 5.5, 403 N; ALLthread Ti 5.0, 526 N; ALLthread Ti 6.5, 653 N; and ALLthread PEEK knotless, 441 N). Mean cortical failure loads for glenoid anchors were 161 N for Gryphon BR P and 239 N for JuggerKnot 1.4. Mean cancellous bone failure loads for cuff anchors were Doubleplay 5.0, 263 N; Doubleplay 6.5, 340 N; Opus SpeedScrew 5.5, 356 N; Opus SpeedScrew 6.5, 344 N; PEEK Intraline 5.5, 274 N; PEEK Intraline 6.5, 327 N; PEEK Zip 5.5, 401 N; PEEK Zip 6.5, 396 N; Paladin 5.0, 427 N; Paladin 6.5, 491 N; SuperRevo FT, 483 N; CrossFT, 547 N; Piton, 365 N; Ti Screw 5.0, 420 N; Ti Screw 6.5, 448 N; ALLthread PEEK 5.5, 475 N; LactoScrew 5.5, 435 N; ALLthread Ti 5.0, 512 N; ALLthread Ti 6.5, 612 N; and ALLthread PEEK knotless, 466 N). Mean cancellous failure loads for glenoid anchors were 117 N for Gryphon BR P and 194 N for JuggerKnot 1.4. None of the anchors had pullout as the predominant failure mode. Eyelet failure was the predominant failure mode for Doubleplay, Opus SpeedScrew, PEEK Intraline, Gryphon BR P, ALLthread Ti 6.5, ALLthread PEEK 5.5, and LactoScrew. Conclusions: Failure load was not dependent on anchor location (cancellous or cortical bone) (P = .58) but was dependent on anchor type (cuff anchor or glenoid anchor) (P < .001). Clinical Relevance: Whereas larger fully threaded screw anchors designed for rotator cuff repair showed higher failure strengths than smaller non-screw anchors designed for glenoid repairs (P < .05), the larger version of a screw anchor for a cuff repair did not provide a statistically greater failure load than the smaller screw anchor.Öğe Biomechanical Comparison of Tibial Eminence Fracture Fixation With High-Strength Suture, EndoButton, and Suture Anchor(W B Saunders Co-Elsevier Inc, 2012) Hapa, Onur; Barber, F. Alan; Suner, Ganim; Ozden, Raif; Davul, Serkan; Bozdag, Ergun; Sunbuloglu, EminPurpose: To biomechanically compare anterior cruciate ligament (ACL) tibial bony avulsion fixation by suture anchors, EndoButtons (Smith & Nephew, Andover, MA), and high-strength sutures subjected to cyclic loading. Methods: Type III tibial eminence fractures were created in 49 ovine knees, and 7 different types of repairs were performed. Each repair group contained 7 specimens. The repair groups were as follows: No. 2 FiberWire (Arthrex, Naples, FL); No. 2 UltraBraid (Smith & Nephew); No. 2 MaxBraid (Arthrotek, Warsaw, IN); No. 2 Hi-Fi (ConMed Linvatec, Largo, FL); No. 2 OrthoCord (DePuy Mitek, Raynham, MA); Ti-Screw suture anchor (Arthrotek); and titanium EndoButton. These constructs were cyclically loaded (500 cycles, 0 to 100 N, 1 Hz) in the direction of the native ACL and loaded to failure (100 mm/min). Endpoints included ultimate failure load (in Newtons); pullout stiffness (in Newtons per millimeter); cyclic displacement (in millimeters) after 100 cycles, between 100 and 500 cycles, and after 500 cycles; and mode of failure. Bone density testing was performed in all knees. Results: Bone density was not different among the groups. The EndoButton group had a higher ultimate failure load than the FiberWire, UltraBraid, Hi-Fi, and suture anchor groups (P < .05). The MaxBraid and OrthoCord groups had higher failure loads than the suture anchor group (P < .05). The MaxBraid group also had a higher failure load than the Hi-Fi group (P < .05). Stiffness was not statistically different for the various tested constructs. After 100 cycles, the EndoButton group had less displacement than the FiberWire, UltraBraid, MaxBraid, and Hi-Fi groups (P < .05). The suture anchor group had less displacement than the Hi-Fi and FiberWire groups (P < .05). The displacements of the different tested constructs between 100 and 500 cycles and total displacements after 500 cycles were not statistically different. The predominant failure mode was suture rupture. Conclusions: Under cyclic loading conditions in an ovine model, EndoButton fixation of tibial eminence fractures provided greater initial fixation strength than suture anchor fixation or fixation with various high-strength sutures except for OrthoCord. Clinical Relevance: During initial cyclic loading of ACL tibial eminence fractures, the strength of the repair construct should be taken into consideration because conventional suture repair even with ultrahighmolecular-weight polyethylene sutures may not provide enough strength.Öğe Comparative Testing by Cyclic Loading of Rotator Cuff Suture Anchors Containing Multiple High-Strength Sutures(W B Saunders Co-Elsevier Inc, 2010) Barber, F. Alan; Hapa, Onur; Bynum, James A.Purpose: To compare isolated medial-row with isolated lateral-row anchor performance by use of cyclic loading followed by destructive testing in an in vitro cadaveric model. Methods: Using 16 human cadaveric humeri without tendons, we rotated 4 medial-row (Bio-Corkscrew FT [Arthrex, Naples FL], CrossFT PK [ConMed Linvatec, Largo, FL], TwinFix PK FT [Smith & Nephew Endoscopy, Andover, MA], and Healix PK [DePuy Mitek, Raynham, MA]) and 4 lateral-row (PopLok PK [ConMed Linvatec], PEEK [polyetheretherketone] PushLock [Arthrex], Footprint PEEK [Smith & Nephew Endoscopy], and Versalok [DePuy Mitek]) anchors among different medial (articular cartilage edge) and lateral greater tuberosity sites (anterior, central, posterior). All medial anchors were inserted into the humeral head at an angle no greater than 45 degrees. All lateral anchors were inserted over the top, nearly planar to the superior humeral surface. After preloading, the constructs were cycled 500 times from 10 to 60 N at 1 Hz with the loads applied to the accompanying sutures. Those constructs surviving cycling were destructively tested. Cyclic displacement, ultimate load, and failure mode were recorded. Results: In this laboratory setting, most displacement occurred in the first 100 cycles except for the Footprint anchor. Lateral-row anchors had greater mean displacements (2.6 mm) than medial-row anchors (1.2 mm) at 100 cycles and between 100 and 500 cycles (1.8 mm v 0.75 mm). Lateral-row anchors also had more total displacement (4.4 mm) than medial-row anchors (1.9 mm). A 5-mm displacement gap, defined as failure, was not seen in the Bio-Corkscrew FT, TwinFix PK FT, and Versalok anchors. Ultimate failure loads ranged from 163 N (Footprint) to 308 N (Versalok) (P < .05). The principal failure mode was anchor pullout, followed by eyelet breakage. Medial-row eyelet failures only occurred after 500 cycles at loads higher than each anchor's mean failure load. Eyelet failure for lateral-row anchors occurred before 500 cycles and at failure loads lower than each anchor's mean. Conclusions: Lateral row anchors benefit from medial row anchors for their security, and because of design differences demonstrate more displacement. When lateral-row anchors fail at the eyelet, it is at lower failure loads, while if medial-row anchors fail at the eyelet, it is at higher loads. Clinical Relevance: Anchors designed to function as lateral-row fixation provide fixation strength inferior to that of medial-row anchors and are more likely to be subject to suture slippage.Öğe A comparison of fucidic acid and cefazoline released from cancellous human bone(Academic Journals, 2011) Dogramaci, Yunus; Kalacı, Aydıner; Ozer, Burcin; Ozden, Raif; Hapa, Onur; Yanat, Ahmet NedimThis study was designed to determine the antibacterial activity of fucidic acid or cefazoline in cancellous bone obtained from patients undergoing total knee replacement. Thirty samples of cancellous bone were obtained from patients undergoing total joint arthroplasty for primary osteoarthritis of knee joints. The prophylactic antibiotics were infused to the subjects an hour before the operation. In the first group (15 samples) fucidic acid (500 mg intravenous) was used as a prophylactic antibiotics and 1st generation of cephalosporin were used in the second group (15 samples) as the prophylaxis. Same strains of Staphyloccocus aureus were used to assess the antibiotic activity using the disc diffusion technique after 1, 3, 7, 10, 14, 18, 21 and 28 days. The antibiotic efficacy was defined as an inhibition zone diameter of 10 mm. Inhibition zone diameters were significantly higher in fusidic acid than cefazoline specimens on the first, third and 14th day after the incubation (P<0.05). No statistically significant difference was found in the inhibition zone diameter at the seventh, 18th and 21st days. Evaluation of inhibition zone diameters showed that samples obtained from the first group (fucidic acid) had a longer duration of antibiotic release than that of second group (cefazolin). Fucidic acid shows a higher release and a longer antibacterial activity when used as a prophylactic antibiotic compared to cefazolin.Öğe The comparison of the effect of corticosteroids and platelet-rich plasma (PRP) for the treatment of plantar fasciitis(Springer, 2012) Aksahin, Ertugrul; Dogruyol, Daghan; Yuksel, Halil Yalcm; Hapa, Onur; Dogan, Ozgur; Celebi, Levent; Bicimoglu, AliIn this study, the results of local injection of platelet-rich plasma (PRP) and corticosteroids in the treatment of plantar fasciitis were compared. Sixty patients who were diagnosed as plantar fasciitis and treated conservatively for at least 3 months and had no response to conservative treatment modalities were involved in this study. The first 30 consecutive patients were treated by local injection of 2 mL of 40 mg Methylprednisolone with 2 mL of 2% prilocaine (metilprednizalone) and the second 30 patients were treated by injecting 3 mL PRP after 2 mL of 2% prilocaine injection. Patients were evaluated according to the modified criteria of the Roles and Maudsley scores and visual analog scale before injection and 3 weeks and 6 months following injection. The mean VAS heel pain scores measured 6 months after treatment were 3.4 in steroid group and 3.93 in PRP group, and the scores in both groups were significantly lower when compared with pretreatment levels (6.2 in steroid group and 7.33 in PRP group). There was no significant difference between steroid and PRP groups in visual analog scale scores and modified criteria of the Roles and Maudsley scores measured at 3 weeks and 6 months ( > 0.05). Our results revealed that both methods were effective and successful in treating plantar fasciitis. When the potential complication of corticosteroid treatment was taken into consideration, PRP injection seems to be safer and at least having same effectivity in the treatment of plantar fasciitis.Öğe The effects of leukotriene receptor antagonist montelukast on histological, radiological and densitometric parameters of fracture healing(2011) Çakıcı, Hüsamettin; Hapa, Onur; Gideroğlu, Kaan; Özturan, Kutay; Güven, Melih; Yüksel, Halil Yalçın; Yılmaz, FahriObjectives: In this study we evaluated the effects of montelukast, a leukotriene-receptor antagonist, on fracture healing, and investigated the hypothesis that enhanced fracture healing would be observed with montelukast in a rat tibia fracture model. Materials and methods: Sixty adult (6 months old) female Wistar albino rats (mean weight 220 g, range 210-270 g) were randomly divided into two groups: a montelukast group (n=30) and a control group (n=30). Closed tibia fractures were created and fixed by intramedullary Kirschner wire. The rats were sacrificed three and six weeks after the fractures. Radiological and histological evaluations were performed, and bone mineral density was measured. Results: Three rats died in the montelukast group, whereas only one died in the control group during the study. Initial weight and weight gain at the 3rd a nd 6 th weeks were not significantly different between the groups (p>0.05). Bone mineral densities in the control and study groups were 0.13±0.009 gr/cm2, and 0.13±0.01 gr/cm2 a t w eek t hree and 0.16±0.02 gr/cm2, and 0.13±0.01 gr/cm2 at week six, respectively. Histopathological scores in the control and study groups were 3.42±0.6, and 3.0±0.0 at week three and 3.5±0.5, and 3.4±0.8 at week six, respectively. Radiological scores in the control and study groups were 1.19±0.6, and 1.0±0.6 at week three and 3.0±0.8, and 2.9±0.9 at week six, respectively. There were no significant differences between the two groups in any parameters evaluated at either time interval (p>0.05). Conclusion: Our study failed to show a possible positive effect of leukotriene receptor inhibition on fracture healing at the 3rd and 6th postoperative weeks.Öğe Effects of montelukast on tendon healing in a murine model(Springer, 2017) Gideroglu, Kaan; Cakici, Husamettin; Hapa, Onur; Ozturan, Kutay E.; Bozdag, Ergun; Yilmaz, Fahri; Saglam, IbrahimBackground Tendon injury induces a local inflammatory response characterized by the production of pro-inflammatory cytokines. The aim of this study is to investigate the effects of montelukast sodium on the healing of tendons through histological and biomechanical evaluations. Methods Forty-eight female Wistar albino rats were randomly assigned to an experimental group that received montelukast sodium (n = 24) and a control group (n = 24) that did not. Tendon injury was created in the Achilles tendon. The experimental group was injected intraperitoneally (IP) with 1 ml of 1 mg/kg montelukast sodium solution once a day prior to the surgery and during the experimental research. The control group was injected with saline solution. Two weeks later, eight rats in each group underwent a histological evaluation. In the fourth week, eight rats underwent a histological evaluation and the other eight rats went through a biomechanical evaluation. Results Based on the histological evaluation in the second week, it was observed that the severity of the inflammation was less in the experimental group that received montelukast sodium (p < 0.05). In terms of the formation of collagen, no significant difference was observed between the groups in the second and fourth weeks. Tendon breaking loads were 33.2 +/- 10.95 and 38.8 +/- 10.90 N for the montelukast group and the control group, respectively. However, the difference between the groups was found to be statistically insignificant (p > 0.05). Conclusions There was no negative effect on the healing of tendons due to injection of montelukast sodium. In addition, observing less inflammation in the experimental group in the earlier phase suggests that montelukast sodium may help in preventing tendon adhesion after reconstructive treatment.Öğe A new surgical technique for the repair of the achilles tendon rupture: repair of the achill tendon rupture by implant without immobilization and compared with traditional suture techniques in rabbits(2010) Aygün, Hayati; Kılıç, Engin; Hüseyinoğlu, Ülfettin; Özaydın, İsa; Ermutlu, Celal Şahin; Alsaran, Akgün; Hapa, Onur; Koca, Kenan; Sözmen, MahmutPurpose of this study was to repair achilles tendon rupture with protection of the integrity of the tendon without the need for the joint immobilization and prevent the complications reported with other techniques. For this purpose, mostly used techniques, Krackow, Modified Kessleer, Bunnel techniques were compared with the newly developed technique using the objective histologic and biomechanic criteria. Depending on the preliminary results of the pull-out tests, 6 tendons were included at each group, consisting of four groups totally. Operations were performed under the anesthesia of xylazine hydrochlorur, bupivacain HCI. At group 1, imlant prepared from the flexible polyethylene material was used. Krackow technique at group 2, Modified Kessler technique at group 3, Bunnell technique at group 4 were utilized. Rabbits were euthanised at 6th week postoperatively by use of overdose of sodium pentobarbital (50 mg/kg). While there was no difference between groups at histological analysis, at biomechanical analysis ultimate load to failure was found to be higher than all other techniques. Depending on these results, newly described technique can be applied clinically and may help to solve this orthopaedic problem.Öğe Rotator Cuff Repair Healing Influenced by Platelet-Rich Plasma Construct Augmentation(W B Saunders Co-Elsevier Inc, 2011) Barber, F. Alan; Hrnack, Scott A.; Snyder, Stephen J.; Hapa, OnurPurpose: To assess the effect of platelet-rich plasma fibrin matrix (PRPFM) construct augmentation on postoperative tendon healing as determined by magnetic resonance imaging (MRI) and clinical outcome of arthroscopic rotator cuff repair. Methods: A comparative series of patients undergoing arthroscopic rotator cuff repair was studied. Two matched groups of patients (20 each) were included: rotator cuff repairs without PRPFM augmentation (group 1) and rotator cuff repairs augmented with 2 sutured platelet-rich plasma (PRP) constructs (group 2). A single-row cuff repair to the normal footprint without tension or marrow vents was performed by a single surgeon. Postoperative rehabilitation was held constant. Postoperative MRI scans were used to evaluate rotator cuff healing. Outcome measures included American Shoulder and Elbow Surgeons, Rowe, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Constant scores. Results: We followed up 40 patients (2 matched groups with 20 patients each) with a mean age of 57 years (range, 44 to 69 years) for a mean of 31 months (range, 24 to 44 months). Postoperative MRI studies showed persistent full-thickness tendon defects in 60% of controls (12 of 20) and 30% of PRPFM-augmented repairs (6 of 20) (P = .03). Of the control group tears measuring less than 3 cm in anteroposterior length, 50% (7 of 14) healed fully, whereas 86% of the PRPFM group tears measuring less than 3 cm in anteroposterior length (12 of 14) healed fully (P = .05). There was no significant difference between groups 1 and 2 in terms of American Shoulder and Elbow Surgeons (94.7 and 95.7, respectively; P = .35), Single Assessment Numeric Evaluation (93.7 and 94.5, respectively; P = .37), Simple Shoulder Test (11.4 and 11.3, respectively; P = .41), and Constant (84.7 and 88.1, respectively; P = .19) scores. The Rowe scores (84.8 and 94.9, respectively; P = .03) were statistically different. Conclusions: The addition of 2 PRPFM constructs sutured into a primary rotator cuff tendon repair resulted in lower retear rates identified on MRI than repairs without the constructs. Other than the Rowe scores, there was no postoperative clinical difference by use of standard outcome measures. Level of Evidence: Level III, case-control study.Öğe Tendon-grasping strength of various suture configurations for rotator cuff repair(Springer, 2011) Hapa, Onur; Barber, F. Alan; Sunbuloglu, Emin; Kocabey, Yavuz; Sarkalkan, Nazli; Baysal, GokhanThe purpose of the present study is to evaluate the mechanical performance and initial strength of the arthroscopic Mason-Allen, double mattress, inclined Mason-Allen, and lasso loop stitch configurations. Using 36 sheep infraspinatus tendons, tendon widths and thicknesses were measured with a digital caliper to confirm standardization of the tendons. Four different stitch configurations (Mason-Allen, inclined Mason-Allen, double mattress, and lasso loop) were biomechanically tested with cyclic loading followed by load to failure testing. The cyclic elongation, peak-to-peak displacement, ultimate tensile strength, stiffness, and mode of failure were recorded. Mean tendon widths and thicknesses were statistically the same. The lasso loop (0.7 +/- A 0.1 mm) demonstrated a mean cyclic elongation greater than the Mason-Allen (0.5 +/- A 0.3 mm) and double mattress (0.5 +/- A 0.3 mm) groups (P = 0.011; P = 0.013). No differences were found in ultimate failure load, stiffness, and peak-to-peak displacement for the Mason-Allen (mean 99 +/- A 42 N, 39 +/- A 9 N/mm, 0.6 +/- A 0,1 mm), inclined Mason-Allen (113 +/- A 52 N, 44 +/- A 14 N/mm, 0.5 +/- A 0.1 mm), double mattress stitch (119 +/- A 68 N, 45 +/- A 10 N/mm, 0.5 +/- A 0.1 mm), or lasso loop (100 +/- A 38 N, 42 +/- A 7 N/mm, 0.5 +/- A 0.1 mm) groups (n.s.). Each specimen failed at the suture-tendon interface. Three specimens (two Mason-Allen and one inclined Mason-Allen) failed during cyclic testing. Conventional Mason-Allen configuration can be applied with double-loaded suture anchor safely. Recent modifications of the configurations offer no biomechanical advantage.Öğe Treatment of Plantar Fasciitis Using Four Different Local Injection Modalities A Randomized Prospective Clinical Trial(Amer Podiatric Med Assoc, 2009) Kalacı, Aydıner; Cakici, Huesamettin; Hapa, Onur; Yanat, Ahmet Nedim; Dogramaci, Yunus; Sevinc, Teoman ToniBackground: To determine the effectiveness of four different local injection modalities in the treatment of plantar fasciitis. Methods: In a prospective randomized multicenter study of plantar fasciitis, 100 patients were divided into four equal groups and were treated using four different methods of local injection: group A was treated with 2 mL of autologous blood alone; group B, an anesthetic (2 mL of lidocaine) combined with peppering; group C, a corticosteroid (2 mL of triamcinolone) alone; and group D, a corticosteroid (2 mL of triamcinolone) combined with peppering. The outcome was defined by using a 10-cm visual analog scale and modified criteria of the Roles and Maudsley score 3 weeks and 6 months after the injection and compared with the pretreatment condition. Results: The successful results in all of the groups after injections were higher than those in the pretreatment condition (P = .000). In groups C and D, in which local corticosteroid injections were used, excellent results were obtained, with superior effect in the group in which peppering was used (P < .05). Conclusions: In the treatment of plantar fasciitis, combined corticosteroid injections and peppering is effective and produces better clinical results. (J Am Podiatr Med Assoc 99(2): 108-113, 2009)
