Return to physical activities after arthroscopic rotator cuff repair: a systematic review and meta-analysis.

Background: Rotator cuff tear is one of the most common disorders in orthopedic surgery. When conservative treatment fails, arthroscopic rotator cuff repair has become the most common procedure to achieve a functional shoulder.

Hypothesis/purpose: The articles on return to activities following arthroscopic rotator cuff repair have not been collectively analyzed and investigated.

Functional outcome of implant-free bone-patellar tendon autograft versus hamstring autograft in arthroscopic anterior cruciate ligament reconstruction: A prospective study.

Introduction: The use of implant in anterior cruciate ligament (ACL) reconstruction has been associated with several drawbacks including graft injury, implant osteolysis, implant migration and soft tissue irritation. Implant-free ACL reconstruction surgery offers additional benefits of cost-effective, improved graft incorporation and ease of revision surgery. Our study aimed to compare the functional outcome of ACL reconstruction by using bone-patellar tendon autograft with press-fit fixation technique and hamstring autografts with implant.

Intra-articular Recombinant Human Growth Hormone Injection Compared with Hyaluronic Acid and Placebo for an Osteoarthritis Model of New Zealand Rabbits.

Purpose: Up to now, there is no feasible solution for stopping or reversing the degenerative process of osteoarthritis (OA). Our study evaluated the effect of intra-articular injection of growth hormone (GH) in OA-induced rabbit knees compared to hyaluronic acid (HA) and placebo.

Materials And Methods: A total of 21 male, skeletally mature, New Zealand rabbits received an intra-articular type II collagenase injection for OA induction.
