Alpine Skiing With total knee ArthroPlasty (ASWAP): clinical and radiographic outcomes

The aim of the study was to assess the effect of a recreational alpine skiing intervention on implant‐related factors, such as loosening and wear, in patients with total knee arthoplasty (TKA). A group of 16 TKA patients were examined 2.3 ± 0.1 years after skiing about 80 days over three seasons inclusive of a ski intervention of 2–3 times per week (25.5 days) over a 12‐week period. Mean follow‐up period was 5.1 ± 1 years after surgery. All patients had excellent clinical and radiological outcomes. The average flexion was 120–130°, the average Oxford Knee Score increased from 15 points pre‐operatively to 47.4 points post‐operatively. An average Tegner activity level of 5.5 was assessed, indicating a very high post‐operative activity level. No radiolucencies or osteolyses were observed in any of the radiographs. One patient sustained a meniscal tear in the contralateral knee. Recreational alpine skiing on intermediate terrain at moderate speed can be recommended after TKA. Analysis of mid‐term follow‐up has not shown any negative effect on the implant loosening or additional polyethylene wear.
