Existing evidence on whether marathon running contributes to hip and knee arthritis is inconclusive. Our aim was to describe hip and knee health in active marathon runners, including the prevalence of pain, arthritis, and arthroplasty, and associated risk factors.

More procedures are being completed on an outpatient basis at freestanding ambulatory surgery centers. The purpose of our study was to determine the safety and rate of adverse events in outpatient hand and upper-extremity surgical procedures.

The use of cementless acetabular components in total hip arthroplasty has gained popularity over the past decade. Most total hip arthroplasties being performed in North America currently use cementless acetabular components. The objective of this systematic review and meta-analysis was to compare the survivorship and revision rate of cemented and cementless acetabular components utilized in total hip arthroplasty.

Glenoid component malposition for anatomic shoulder replacement may result in complications. The purpose of this study was to define the efficacy of a new surgical method to place the glenoid component.

Concepts: Medicine, Effectiveness


Much of the difficulty in understanding acetabular fracture patterns is due to the complex three-dimensional relationship of the acetabulum to the greater pelvis. We hypothesized that combining three-dimensional “hands-on” anatomic models with two-dimensional informational teaching sheets would improve the ability of orthopaedic residents to accurately classify acetabular fracture patterns and aid in preoperative surgical approach selection.

Untreated ulnar collateral ligament (UCL) injury of the thumb metacarpophalangeal joint (MCPJ) can lead to long-term pain and functional limitations.Detection of a UCL injury involves sequential examination of true and accessory ligaments and comparison with the uninjured side.Acute partial UCL injuries can be successfully treated nonoperatively.Acute complete or displaced UCL injuries can be successfully treated with operative repair.In cases of chronic UCL injury, treatment options include static and dynamic reconstructions.If painful arthrosis is present with chronic UCL instability, salvage may be performed with MCPJ fusion.

Despite meticulous hemostasis, persistent postoperative drain output following posterior cervical spine procedures often necessitates a prolonged length of hospital stay. We sought to determine if thrombin-soaked absorbable gelatin compressed sponge can decrease postoperative drain output and the length of hospital stay after multilevel posterior cervical spine surgery.

An avulsion of the posterior root attachment of the lateral meniscus or a radial tear close to the root attachment can lead to degenerative knee arthritis. Although the biomechanical effects of comparable injuries involving the medial meniscus have been studied, we are aware of no such study involving the lateral meniscus. We hypothesized that in situ pull-out suture repair of lateral meniscus root avulsions and of complete radial tears 3 and 6 mm from the root attachment would increase the contact area and decrease mean and peak tibiofemoral contact pressures, at all knee flexion angles, relative to the corresponding avulsion or tear condition.

Degloving injuries of the foot with involvement of the heel and sole occur relatively rarely but pose an extreme challenge to the reconstructive surgeon due to the unique anatomy of the foot. Very limited studies are available regarding the outcomes of reattachment of the degloved skin as a full-thickness graft.

We asked whether cementless total hip arthroplasties that made use of alumina-on-highly cross-linked polyethylene bearings would improve hip score and functional activity and reduce the prevalence of polyethylene wear, osteolysis, and aseptic loosening.
