BACKGROUND Arthrofibrosis, occurring in 3%-4% of patients following total knee arthroplasty (TKA), is a challenging condition for which there is no defined cause. The hypothesis for this study was that disregulated production of reactive oxygen species (ROS) and nitrogen species (RNS) mediates matrix protein and DNA modifications, which result in excessive fibroblastic proliferation. RESULTS ...

PURPOSE The purpose was to review the literature on the outcomes of elbow arthroscopy and to make evidence-based recommendations for or against elbow arthroscopy for the treatment of various conditions. Our hypothesis was that the evidence would support the use of elbow arthroscopy in the management of common elbow conditions. METHODS A literature search was performed by use of the PubMed dat...

OBJECTIVE To report functional outcome in Posterior Cruciate Ligament (PCL) tibial avulsion fractures treated with open reduction and internal fixation through Burks and Schaffer approach. The patient specific functional outcome measures like IKDC grading together with objective grading with stress radiographs have rarely been used -to assess PCL tibial avulsion fractures. MATERIAL AND METHOD...

let, MD, FRCS(C) ind Ankle Center 'leveland Avenue Suite 100 imbus, OH 43231 Considerable attention has been given to the subtalar joint as an area of injury and pathology.--^ 27 Subtalar injuries frequently occur in combination with other injuries, especially sprains of the lateral ankle ligaments. Because lateral ankle sprains rank as the most common source of time-loss injury in sports, it f...

A patient with a history of total knee arthroplasty and 5 subsequent revisions presented with pain. His preoperative construct consisted of a revision implant with porous in-growth stem extensions. He was indicated for revision surgery for a painful implant with progressive arthrofibrosis. The surgery proceeded uneventfully until we were unable to loosen the proximal portion of the ingrown femo...

No data on the results of total knee arthroplasty (TKA) in patients with fibromyalgia have been published. The purposes of this study were to review a cohort of patients with fibromyalgia undergoing TKA to determine the level of postoperative pain and satisfaction with the surgery, the incidence of postoperative surgical complications, and revision rates and their relationship to TKA design. On...

BACKGROUND Subsequent surgeries have a profound effect on patient satisfaction and outcome after primary anterior cruciate ligament reconstruction (ACLR). There have been no prospective studies to date describing the rate and predictors (surgical and patient variables) of all subsequent knee surgeries at short-term and midterm follow-up along with analyses of surgical and patient variables that...

OBJECTIVE To determine and compare failure, re-operation, and complication rates of all generations and techniques of autologous chondrocyte implantation (ACI). METHODS A systematic review of multiple medical databases was performed according to PRISMA guidelines. Levels I-IV evidence were included. Generations of ACI and complications after ACI were explicitly defined. All subject and defect...
