[Supramalleolar, subtractive valgus osteotomy of the tibia in the management of ankle joint degeneration with varus deformity].

Objective: The aim of supramalleolar osteotomy of the tibia in the management of varus deformity of the upper ankle joint is to shift load bearing away from the severely degenerated medial part of the joint to the lateral part and thus restore physiological alignment of the hindfoot and a plantigrade foot. The intention is to reduce pain and to postpone the need for total endoprosthesis or arthrodesis.

Indications: Painful degeneration of the ankle joint with varus deformity that has proven resistant to conservative treatment, i.

Cementless CUT femoral neck prosthesis: increased rate of aseptic loosening after 5 years.

Background: Bone-saving hip arthroplasty techniques, which facilitate revision, are gaining importance as the number of hip replacements in younger patients increases.

Patients And Methods: 123 CUT femoral neck prostheses (ESKA Implants, Lübeck, Germany) were implanted in 113 patients (average age 53 years) between 1999 and 2002. After a mean follow-up of 5 (3-7) years, we determined the state of 120 prostheses; 3 patients could not be located.

Evaluation of arthroscopic articular cartilage biopsy for osteoarthritis of the knee.

PURPOSE: Arthroscopic evaluation of the articular surface by visualization and palpation has proved to be unreliable; therefore, we investigated arthroscopically procured biopsy specimens and conventional sections by using the same histopathomorphologic techniques and compared the results for possible differences. METHODS: Cartilage biopsy specimens of 1.7 mm in diameter and conventional cartilage sections (pieces of 8 x 2 mm) were removed from the lateral femoral condyle of 53 osteoarthritis patients undergoing total knee arthroplasty.
