Background: Patient-Reported Outcomes Measurement Information System (PROMIS) scores can quantify symptomsand limitations after upper extremity surgery. Our objective was to determine how these scores compare amongstpatients with trapeziometacarpal osteoarthritis treated either nonoperatively or operatively.Methods: In this retrospective comparative study, we compared PROMIS s...

PREFACE 3 Preface It is indeed a pleasure to present our report of research activities 2001-2002. We thank you for your interest and your support during the last two years. We hope that this information is of use to you and look forward to continuing what has become excellent cooperation. Biomechanical analysis of biodegradable interbody fusion cages augmented with Poly(propylene glycol-co-fuma...

background: rupture of anterior cruciate ligament (acl) would cause instability and disability and if left untreated. reconstruction is performed by different techniques including patellar bone graft, as the strongest device. application of brace after acl reconstructions has revealed doubtful results.   methods: one hundred acl ruptured patients randomized into two groups were reconstructed wi...

  Background: Despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. Hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring ten...

Background This study aimed to compare stability, functional outcome, and second-look arthroscopic findings after anterior cruciate ligament reconstruction between remnant-preserving tibialis tendon allograft and remnant-sacrificing hamstring tendon autograft. Methods We matched two groups (remnant-preserving tibialis tendon allograft group and hamstring tendon autograft group) in terms of de...

background anterior cruciate ligament (acl) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. in cases with minor injuries, conservative treatments suffice. but, in cases with acl tear, surgery by different methods and autografts are indicated. the most prevalent method for acl reconstruction is the use of hamstring tendo...

This article presents a case of a large inferior patellar osteophyte, which developed after patellar tendon autograft anterior cruciate ligament (ACL) reconstruction. This extensive osteophyte formed a neo-articulation with the tibial plateau and contributed to arthrofibrosis, patellar baja, and patellar pain. This is an extremely unusual complication following patellar tendon harvesting for AC...

The multiple-ligament injured knee is a complex problem in orthopaedic surgery. Most dislocated knees involve tears of the anterior and posterior cruciate ligaments (ACL/PCL) and at least 1 collateral ligament complex. Careful assessment of the extremity vascular status is essential because of the possibility of arterial and/or venous compromise. These complex injuries require a systematic appr...

BACKGROUND Successful anterior cruciate ligament reconstruction with use of soft-tissue grafts requires healing between tendon and bone. Little is known about the effect of mechanical load on the cellular and molecular cascade of tendon-to-bone healing. Understanding these mechanical influences has critical implications for postoperative rehabilitation following anterior cruciate ligament recon...

Chronic medial knee instability is frequently due to a combination of superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) insufficiency. We present a new technique for simultaneous anatomical reconstruction of sMCL and POL, using an anterior tibialis tendon allograft with three reconstruction tunnels.
