The purpose of this study was to provide comprehensive long-term data about sports activity levels in patients following total knee arthroplasty (TKA) and to determine the impact of pre-operative function, pain and specific performed sports on the results. 236 patients who have undergone TKA for severe osteoarthritis of the knee were asked to provide specific information regarding exercised types of sports before surgery and after at least 10 years following TKA. Pre- and postoperative function and pain were evaluated by the use of Tegner-, WOMAC- and VAS Score. After a mean of 14.9 years, a significant improvement regarding pain and function was observed. Pre-operative Tegner- and WOMAC scores revealed significant positive correlations with the post-operative Tegner-Score. Accordingly, a high percentage of patients (70.9%) stayed actively involved in sports. Nevertheless, the number of performing patients has decreased according to the sports impact. 71.3% continued practising low-impact-, 43.7% intermediate-impact sports whereas only 16.4% kept performing high impact sports. We conclude that TKA is highly effective in long-time pain reduction as well as improvement of function. Additionally, we found considerable sports activities preserved in the investigated series. However, sports activities in particular, seem to decrease according to the impact of sports.
本研究的目的是提供全膝关节置换术（TKA）患者运动活动水平的全面长期数据，并确定术前功能、疼痛和特定运动对结果的影响。236例因重度膝关节骨关节炎接受TKA手术的患者被要求提供有关术前以及TKA术后至少10年所进行的运动类型的具体信息。使用Tegner评分、WOMAC评分和视觉模拟评分（VAS）评估术前和术后的功能及疼痛情况。平均14.9年后，观察到疼痛和功能有显著改善。术前Tegner评分和WOMAC评分与术后Tegner评分呈显著正相关。相应地，高比例患者（70.9%）仍积极参与运动。然而，根据运动的影响，参与运动的患者数量有所减少。71.3%的患者继续进行低强度运动，43.7%的患者进行中等强度运动，而只有16.4%的患者继续进行高强度运动。我们得出结论，TKA在长期减轻疼痛以及改善功能方面非常有效。此外，我们发现在所研究的系列中仍保留了相当多的体育活动。然而，特别是体育活动似乎会根据运动的影响而减少。
