BACKGROUND The palmaris longus tendon is frequently used as a tendon graft or ligament replacement. In rare instances the median nerve has been inadvertently harvested instead of the palmaris longus for use as a tendon. METHODS Nineteen cases in which the median nerve had been mistakenly harvested instead of the palmaris longus tendon were collected from members of the American Society for Su...

BACKGROUND Zone 2 flexor tendon injuries still represent a challenging problem to hand surgeons despite the well developed surgical techniques and suture materials. Meticulous surgical repair with atraumatic handling of the severed tendon stumps and minimal damage to the tendon sheath are particularly important to prevent postoperative adhesions and ruptures in this area.In zone 2 flexor tendon...

BACKGROUND Anatomic double-bundle reconstruction has been thought to better simulate the anterior cruciate ligament anatomy. It is, however, a technically challenging procedure, associated with longer operation time and higher cost. HYPOTHESIS Double-bundle anterior cruciate ligament reconstruction using a single femoral and tibial tunnel can closely reproduce intact knee kinematics. STUDY ...

Acute simultaneous rupture of the anterior cruciate ligament (ACL) and patellar tendon is a rare injury. We present a case report of a 32-year-old male patient with ruptured ACL and ipsilateral patellar tendon rupture sustained while playing baseball. Surgery was performed on the patellar tendon and the ACL simultaneously. The clinical and radiological outcomes of the treatment were successful....

Introduction Rectus femoris is a spindle shaped muscle forming part of the quadriceps muscle group in the anterior compartment of the thigh. Traditionally, it is described as having two heads which arise as a straight tendon from the anterior inferior iliac spine and a reflected tendon from the ilium just above the acetabulum. Recent studies have shown that the anatomy of the muscle is more com...

Complications of patellar-tendon allograft for anterior cruciate ligament (ACL) reconstruction in ACL-deficient patients have focused on disease transmission, strength, survivorship, technique, and processing to decrease antigenicity. Little has been described in regard to intrinsic complications of patellar-tendon allograft. This article discusses our experience with a damaged patellar-tendon ...

Anterior cruciate ligament reconstruction with patellar tendon allograft tissue is a common orthopedic procedure. It is unknown what effect, if any, the donor age has on clinical outcomes. Biomechanical studies have shown the strength of cadaveric patellar tendon to be independent of age, but no clinical studies have evaluated patient outcomes related to this variable. The purpose of this study...

A mesenchymal stem cell (MSC)-seeded collagen gel under static or dynamic tension is a well-established model to study the potential of MSCs in regenerating a tendon- or ligament-like tissue. Using this model, upregulation of fibrillar collagen mRNA expression and protein production has been demonstrated in response to cyclic tensile mechanical stimulation. However, the mechanisms driving MSC t...

Of eithty-six patients with collateral ligament instability of the metacarpophalangeal joint of the thumb, sixty-six (77 per cent) had ulnar and twenty (23 per cent) had radial instability, while in addition twenty-four had fractures and twenty-nine had volar subluxation of the proximal phalanx. Of the sixty-nine patients operated on, sixty-five had an abnormality of the ulnar or radial collate...

Medial patellofemoral instability is a rare, disabling condition that is often associated with the wrong indication for lateral retinacular release or overcorrection with medializing tibial tubercle osteotomy. It is an even less common complication after total knee arthroplasty (TKA). The lateral patellofemoral ligament is an important lateral stabilizer of the patella against medial subluxatio...
