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.
