BACKGROUND Biomechanical analysis of stop-jump tasks has demonstrated gender differences during landing and a potential increase in risk of noncontact anterior cruciate ligament injury for female athletes. Analysis of landing preparation could advance our understanding of neuromuscular control in movement patterns and be applied to the development of(More)
Acute isolated rupture of the patellar tendon traditionally has been repaired via transpatellar suture tunnels. This retrospective study evaluated the demographics and epidemiology of this injury as well as the effectiveness and complication rates of our suture anchor technique. Between 1993 and 2005, a total of 82 cases of patellar tendon disruption in 71(More)
Quadriceps tendon rupture is an incapacitating injury that usually requires surgical repair. Traditional repair methods involve transpatellar suture tunnels, but recent reports have introduced the idea of using suture anchors to repair the ruptured tendon. We present 5 cases of our technique of using suture anchors to repair the ruptured quadriceps tendon.
BACKGROUND Graft survivorship, reinjury rates, and career length are poorly understood after anterior cruciate ligament (ACL) reconstruction in the elite collegiate athlete. The purpose of this study was to examine the outcomes of ACL reconstruction in a National Collegiate Athletic Association (NCAA) Division I athlete cohort. STUDY DESIGN Case series;(More)
BACKGROUND Thermal microdebridement for the treatment of chronic tendinopathy has recently been introduced. The effect of thermal microdebridement on the biomechanical properties of human tendons, however, remains unknown. HYPOTHESIS Thermal microdebridement does not affect the biomechanical properties of human patellar tendons in a cadaveric model at the(More)
The objective of this study was to determine the effect of a lateral meniscus allograft on the articular contact area and pressures across the glenohumeral joint under compressive loads of 220 N and 440 N. Eight fresh-frozen shoulders were used, and contact areas and pressures were determined with a Tekscan flexible tactile force sensor. Testing conditions(More)
PURPOSE The purpose of this study was to objectively assess glenohumeral volume changes after arthroscopic suture plication, arthroscopic thermal capsulorrhaphy, and combined suture and thermal treatment. TYPE OF STUDY Cadaveric study. METHODS Five matched pairs of cadaver shoulders were treated with either thermal capsulorrhaphy (n = 5) or arthroscopic(More)
Clinical experience with humeral implants has evolved over the past decade, along with a better understanding of shoulder anatomy and function. There is no question that surgeons are getting better at restoring normal anatomic relationships than in preceding decades. Whether or not this impacts implant longevity will only be known with time and further(More)
BACKGROUND Subscapularis dysfunction following total shoulder arthroplasty can result in permanent loss of function. The lesser tuberosity osteotomy (LTO) has been proposed as a method which utilizes bone-to-bone healing to improve subscapularis function. This study evaluates the biomechanical properties of two described techniques for LTO repair. We(More)
BACKGROUND Patients have high reinjury rates after ACL reconstruction. Small knee flexion angles and large peak posterior ground reaction forces in landing tasks increase ACL loading. QUESTIONS/PURPOSES We determined the effects of a knee extension constraint brace on knee flexion angle, peak posterior ground reaction force, and movement speed in(More)
