[Peroneal nerve palsy after total knee arthroplasty under continuous epidural anaesthesia].

Background: Peroneal nerve palsy is a rare but distressing complication of total knee arthroplasty (TKA). After introducing a standardised intraoperative and postoperative epidural anaesthesia protocol under otherwise unchanged perioperative management, we noted a sudden cumulation of peroneal nerve palsies after TKA.

Patients And Methods: In this retrospective study we checked the patients' histories for well-known risk factors for nerve lesions after TKA as well as for those risk factors controversially discussed in the literature.

Ten-year results of uncemented hip stems for failed intertrochanteric osteotomy.

Introduction: Inferior survival of cemented total hip arthroplasty has been reported after previous femoral osteotomy. The purpose of this study was to evaluate the long-term survival of uncemented stems after femoral osteotomy.

Materials And Methods: Forty-eight hips in 45 patients had undergone conversion THA for a failed intertrochanteric osteotomy of the hip after a mean of 12 years (2-33 years).

Long-term fate of uncemented, threaded acetabular components with smooth surface treatment: minimum 10-year follow-up of two different designs.

Introduction: In the 1970s and 1980s, uncemented, threaded acetabular components with smooth surface treatment were widely used in continental Europe for arthroplasty of the hip to overcome the high rate of aseptic loosening in cemented hip arthroplasty in young patients. There were several reports on short- and intermediate-term results, but information on survival in the longer term is not available at present.

Materials And Methods: In a consecutive series of 320 patients, 348 threaded cups with smooth surface treatment (221 Mecring and 127 Weill) had been implanted in combination with one type of uncemented stem.

High prevalence of hip arthrosis in former elite javelin throwers and high jumpers: 41 athletes examined more than 10 years after retirement from competitive sports.

We studied the occurrence of hip arthrosis in 19 former elite javelin throwers and 22 former elite high jumpers 10 years or more after their retirement from competitive sports. Any restriction in the activities of daily living was assessed with an ADL-questionnaire. We compared the radiographic findings with male, age- and body mass index-matched controls (non-athletes).
