Computerized matching of autologous femoral grafts for the treatment of medial talar osteochondral defects.

Background: Cored autologous graft from the distal ipsilateral femur has been used to fill osteochondral defects in the talus. There are no studies that compare the articular morphology of potential donor sites on the distal femur with recipient sites on the talus.

Methods: Using coronal MRI of the talus and distal femur of five matched cadaver, computer reconstructions of the articular surfaces were prepared.

Three-dimensional shape of the dysplastic femur: implications for THR.

This study evaluates the three-dimensional anatomy of the femur with congenital dysplasia of the hip (CDH) in comparison with healthy controls. Computed tomographic scans were obtained from 207 women (154 with dysplasia; 54 healthy controls) with an average age of 51.6 years (range, 18-82 years).

Functional bracing for distal radioulnar joint instability.

Symptomatic chronic distal radioulnar joint (DRUJ) instability can be a challenging disorder to treat surgically. This study used a cadaver model to assess the effect of functional forearm bracing on DRUJ instability. The specimen upper extremities were mounted on a platform and the DRUJ was destabilized sequentially.

A biomechanical analysis of meniscal repair techniques.

Background: Various methods are available for repair of meniscal tears: a biodegradable meniscal implant without sutures (Biofix meniscus arrow), a suture anchor device (T-fix), and horizontal and vertical mattress sutures.

Hypothesis: There is no difference in repair strength or mode of failure among the techniques compared.

Study Design: Controlled laboratory study.
