Total knee arthroplasty following medial opening wedge tibial osteotomy: technical issues early clinical radiological results.

Medial opening wedge high tibial osteotomy is a popular treatment option for medial compartment osteoarthritis of the knee. One of the proposed advantages is easier conversion to a total knee replacement compared to lateral closing wedge osteotomies, although there are few studies to support this. We reviewed the technical considerations in 36 knees in which conversion of a medial opening wedge osteotomy to total knee arthroplasty was performed, and contrasted these to previously reported studies of knee arthroplasty after closing lateral wedge or dome osteotomies.

Ten-year results of an inset biconvex patella prosthesis in primary knee arthroplasty.

Unlabelled: The inset biconvex patella component is an alternative form of patella resurfacing in knee arthroplasty. We retrospectively reviewed 433 patients in whom 521 patella prostheses were implanted before April 1997 to determine survivorship, factors associated with failure of the implant, incidence of anterior knee pain, and factors that may be associated with the latter. We had clinical results for 204 surviving patients (242 knees) without failure of their implants with a minimum 10-year followup (mean, 11.

The cemented inset biconvex patella in revision knee arthroplasty.

Evaluation of a cemented biconvex inset patellar component used in revision knee arthroplasty at minimum five year follow-up was undertaken. Of the initial cohort of 89 knees in 85 patients, two patellar implants were revised for aseptic loosening following a transverse fracture of the patella associated with avascular necrosis. A further four implants were judged radiographically loose.

Acromioclavicular reconstructions with hamstring tendon grafts: a comparative biomechanical study.

The surgical treatment of chronic acromioclavicular injuries remains controversial. There is increasing use of autogenous tendon grafts to perform these reconstructions. This study examined the mechanical properties of differing configurations of these grafts.

Fractional lengthening of forearm extensors for resistant lateral epicondylitis.

Background: This study presents the surgical technique of fractional lengthening of extensor carpi radialis brevis, extensor digitorum communis and the superficial head of supinator, for chronic lateral epicondylitis. The anatomical basis for this surgical approach is reviewed. The results of surgical treatment in a consecutive series of patients with severe chronic lateral epicondylitis are reviewed.
