BACKGROUND: The Nice knot is a bulky double-stranded knot. Biomechanical data supporting its use as well as the number of half hitches required to ensure knot security is lacking. MATERIALS AND METHODS: Nice knots with, one, two, or three half-hitches were compared with the surgeon's and Tennessee slider knots with three half hitches. Each knot was tied 10 times around a fixed diameter using four different sutures: FiberWire (Arthrex, Naples, FL), Ultrabraid (Smith and Nephew, Andover, MA), Hi-Fi (ConMed Linvatec, Largo, FL) and Force Fiber (Teleflex Medical OEM, Gurnee, IL)...

UNLABELLED: There are several options for LHB tenodesis; yet, there is no standard of care. This technical note describes an extramedullary all-suture anchor technique for LHB tenodesis that is similar to the extramedullary cortical button technique. The LHB tenodesis is performed by using the Y-Knot (1.3-mm; ConMed Linvatec, Largo, FL).The biceps tenotomy is completed arthroscopically, and a standard subpectoral approach is used for the tenodesis. A reamer is first used to drill through the anterior cortex of the humerus; subsequently, a 1...

PURPOSE: The purpose of this study was to evaluate the biomechanical behavior of an all-suture glenoid anchor in comparison with a more conventional screw-in glenoid anchor, with regard to maximum load to failure and tensile displacement. METHODS: All mechanical testing was performed using an Instron ElectroPuls E1000 mechanical machine, with a 10 N pre-load and displacement rate of 10 mm/min. Force-displacement curves were generated, with calculation of maximum load, maximum displacement, displacement at 50 N and stiffness...

Exertional compartment syndrome of the leg is a condition that can cause chronic debilitating pain in active persons during a variety of aerobic activities. Nonoperative treatments using stretching protocols and activity modifications are often unsuccessful, and thus several operative strategies have been used to treat this condition. A novel technique for endoscopically assisted fasciotomy for chronic exertional compartment syndrome is described. By use of a small laterally based incision and an arthroscope, polydioxanone sutures are passed percutaneously along the anterior and lateral compartments with the Spectrum suture-shuttling device (ConMed Linvatec, Largo, FL)...

PURPOSE: The purpose of this study was to evaluate the biomechanical and design characteristics of newer suture anchors under cyclic loading. METHODS: Suture anchors were tested in fresh porcine cortical and cancellous bone by cyclic loading (10 to 100 N for 200 cycles) followed by destructive testing parallel to the insertion axis at 12.5 mm per second. End points included ultimate failure load, displacement at 100 and 200 cycles, failure mode, and stiffness. Anchors tested included ReelX (Stryker Endoscopy, San Jose, CA); Footprint Ultra PK (4...

A 16-year-old male who had undergone 6 months before an anterior cruciate ligament (ACL) reconstruction with an autologous hamstring graft fixed with a suspensory fixation device (XoButton device; ConMed Linvatec, Largo, FL), complained of a slightly painful mass in the distal posterolateral aspect of the thigh. The knee was otherwise stable. A 79 × 60 × 17 mm multilobulated tumor surrounding the implant device was observed in magnetic resonance images. The revision arthroscopy showed an intact ACL graft...

PURPOSE: To compare biomechanical fixation and gapping characteristics of a new all-inside meniscus repair method for radial meniscus lesion repair versus conventional inside-out suture repair under submaximal cyclic loading and load-to-failure test conditions. METHODS: Fresh-frozen porcine tibiae with attached lateral menisci and joint capsules were harvested and stored for 48 hours at -20°C. After thawing for 12 hours, equivalent-size healthy specimens were randomly assigned to 2 groups of 8 specimens each...

PURPOSE: To evaluate the biomechanical characteristics of recently introduced ultrahigh-molecular-weight polyethylene suture-based, self-adjusting meniscal repair devices. METHODS: Updating a prior study published in 2009, we made vertical longitudinal cuts 3 mm from the periphery in fresh-frozen adult human menisci to simulate a bucket-handle meniscus tear. Each tear was then repaired by a single repair technique in 10 meniscus specimens. Group 1 menisci were repaired with a vertical mattress suture of No...

PURPOSE: 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...

PURPOSE: The purpose of this study was to determine the clinical results of deep-fascial medial and lateral portals in performing endoscopic surgery for plantar fasciitis. METHODS: In 10 feet in 8 patients who were treated conservatively for more than 6 months with failure to relieve their symptoms, endoscopic surgery was performed. After the patient was placed in the supine position, a medial portal was made 5 mm deep to the plantar fascia and 10 mm anterior to its origin on the calcaneus under fluoroscopy...

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)...

PURPOSE: To compare drilling the femoral tunnel with an offset aimer and BullsEye guide (ConMed Linvatec, Largo, FL) to perform an anatomic single-bundle reconstruction of the anterior cruciate ligament (ACL) through the anteromedial portal. METHODS: Seven matched pairs of cadaveric knees were studied. The intent was to drill the femoral tunnel anatomically in all cases. In group A the femoral tunnel was drilled arthroscopically with an offset aimer. In group B the femoral tunnel was drilled arthroscopically with the BullsEye guide...

PURPOSE: The purpose of this study was to assess the outcome of endoscopic plantar fascia release (EPFR) after failed extracorporeal shock wave therapy (ESWT). METHODS: Eighteen patients (twenty-one feet) had persistent painful heel after treatment by ESWT for at least 6 months. The treatment protocol included 2,000 pulses of 0.12 mJ/mm(2) given in 1 session weekly for 7 sessions. Preoperative and postoperative assessment of pain and functional evaluation were done blindly by the second author using a visual analog scale (VAS) score and the modified American Orthopaedic Foot & Ankle Society (AOFAS) score for the hindfoot...

PURPOSE: The purpose of this in vitro biomechanical study was to determine the cyclic elongation and failure properties of a new anterior cruciate ligament (ACL) reconstruction device and compare the results with several devices that are currently available. METHODS: We performed 10 ACL reconstructions in 4 groups using fresh porcine femurs and doubled lateral extensor of the toes tendons. Manufacturer guidelines were followed for fixation by use of either of 2 cortical suspension devices (XO Button [ConMed Linvatec, Largo, FL] and EndoButton CL [Smith & Nephew, Andover, MA]), a bio-interference screw (BioScrew; ConMed Linvatec), or a corticocancellous fixation device (Pinn-ACL; ConMed Linvatec)...
