ReviewTiming of tourniquet release in knee arthroplasty. Meta-analysis of randomized, controlled trials.
Some surgeons release the tourniquet before closing the wound to secure hemostasis during knee arthroplasty. We examined whether early tourniquet release could reduce the perioperative blood loss and whether not releasing the tourniquet until after wound closure would increase the risk of early postoperative complications. ⋯ Therapeutic Level II.

Fresh stored allografts for the treatment of osteochondral defects of the knee.
Osteochondral allograft reconstruction of articular cartilage defects is a well-established cartilage repair strategy. Currently, fresh osteochondral allograft tissue is commercially available to clinicians approximately thirty days following graft harvest. Little clinical information is available on the outcome of patients who have been treated with fresh allografts stored for several weeks or more. The purpose of this study was to prospectively analyze the clinical outcome and graft morphology of patients who received fresh, hypothermically stored, allograft tissue for the treatment of symptomatic chondral and osteochondral defects of the knee. ⋯ Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

Loss of pin fixation in displaced supracondylar humeral fractures in children: causes and prevention.
Although the results are generally good following pin fixation of supracondylar humeral fractures in children, occasionally there is postoperative displacement. The purposes of the present study were to identify the causes leading to loss of fixation after pin fixation and to present methods for prevention. ⋯ Therapeutic Level III. See Instructions to Authors for a complete description of levels of evidence.

Projections of primary and revision hip and knee arthroplasty in the United States from 2005 to 2030.
Over the past decade, there has been an increase in the number of revision total hip and knee arthroplasties performed in the United States. The purpose of this study was to formulate projections for the number of primary and revision total hip and knee arthroplasties that will be performed in the United States through 2030. ⋯ These large projected increases in demand for total hip and knee arthroplasties provide a quantitative basis for future policy decisions related to the numbers of orthopaedic surgeons needed to perform these procedures and the deployment of appropriate resources to serve this need.
