Initial experience with the oxford unicompartmental knee arthroplasty.

Our initial experience with mobile bearing medial compartment unicompartmental arthroplasty (UKA) is presented to highlight lessons that have been learned to avoid short-term failures. Consecutive cases of the Oxford medial UKA performed between February 2001 and April 2006 were reviewed to derive those cases that were revised to total knee arthroplasty (TKA). There were 545 patients available with mean age and body mass index of 65.

The effect of the wafer procedure on pressure in the distal radioulnar joint.

Purpose: To investigate the effect of the wafer procedure on pressure within the distal radioulnar joint.

Methods: The effect of increasing transverse distal ulnar head resection with preservation of the ulnar styloid was evaluated in 4 fresh frozen cadaver arms. Specimens were tested in neutral rotation.
