Although total knee replacement is an excellent treatment of end-stage osteoarthritis of the knee in the older (>65 years) population, many patients with less severe disease are significantly impacted by their symptoms and have failed to respond to less invasive treatment alternatives. For this group, there are several less invasive surgical alternatives, including arthroscopic meniscectomy, grafting of symptomatic areas of bone marrow lesions, unloading osteotomy, and unicompartmental knee replacement. Current total knee arthroplasty designs can be expected to survive 20 years or more in the older, less active population. New materials may extend that survivorship.
虽然全膝关节置换术是治疗老年（>65 岁）人群膝关节晚期骨关节炎的一种极好方法，但许多病情较轻的患者其症状受到严重影响，且对非侵入性治疗选择没有反应。对于这一组患者，有几种非侵入性的手术选择，包括关节镜下半月板切除术、有症状的骨髓病变区域的移植物、减压截骨术和单髁膝关节置换术。目前的全膝关节置换设计预计在年龄较大、活动量较小的人群中可以使用 20 年或更长时间。新材料可能会延长其使用寿命。
