»: Both unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) allow for compartment-specific intervention on an arthritic knee joint that preserves bone stock and native soft tissue compared to a total knee arthroplasty (TKA). Both operations give a more natural feeling with native proprioception compared with a TKA.
»: HTO is better suited in patients who are younger (<55 years-of-age), have a body mass index (BMI) <30 kg/m2, high activity requirements, mechanical malalignment, asymmetric varus, isolated anterior cruciate ligament insufficiency, need for multiplanar correction, and a preference for joint preserving interventions. Recent data suggest that age (>55 years-of-age) should not solely contraindicate a HTO.
»: UKA may be chosen in patients who are older (>55 years-of-age), low activity requirements, have a BMI <40 kg/m2, severe osteoarthritis with significant joint space narrowing, acceptable coronal alignment, symmetric varus, and patient preference for arthroplasty.
»: 单髁膝关节置换术（UKA）和胫骨高位截骨术（HTO）都可以针对关节炎膝关节进行特定部位的干预，与全膝关节置换术（TKA）相比，保留了骨量和原生软组织。与 TKA 相比，这两种手术都具有更自然的本体感觉。
»: HTO 更适合年龄较小（<55 岁）、体重指数（BMI）<30 kg/m2、活动要求高、机械对线不良、不对称性内翻、单纯前交叉韧带功能不全、需要多平面矫正以及对关节保留干预有偏好的患者。最近的数据表明，年龄（>55 岁）不应单独成为 HTO 的禁忌症。
»: UKA 可用于年龄较大（>55 岁）、活动要求低、BMI<40 kg/m2、严重关节炎伴明显关节间隙狭窄、冠状面对线可接受、对称性内翻以及患者对关节置换有偏好的患者。
