The aim of this prospective follow-up study was to determine if gait measurements and/or clinical measurements could detect differences in treatment outcome between two surgical interventions in patients with knee osteoarthritis (OA). The patients were followed for 5 years after surgery. Forty patients, 55-70 years of age, with unilateral knee OA were included. The patients were treated either with a high tibial osteotomy (HTO) (n=18) or a unicompartmental knee arthroplasty (UKA) (n=22). Clinical outcome measures were the British Orthopaedic Association (BOA) score, pain during walking, passive range of knee motion (PROM) and patients' subjective opinion. The gait variables were free walking speed, step frequency, step length and single and double-stance phase for each leg. The patients were examined before surgery and 3 months, 1 year and 5 years after surgery. The time-distance variables of gait could detect differences in treatment outcome, 3 months after surgery, while the clinical outcome measures, as given here, could not detect any differences between the two groups of patients. Measurements of free walking speed could be recommended for clinical evaluation, after surgical interventions, in patients with knee OA.
这项前瞻性随访研究的目的是确定步态测量和/或临床测量能否检测出膝关节骨关节炎（OA）患者两种手术干预治疗效果的差异。患者术后随访5年。纳入了40例年龄在55至70岁之间的单侧膝关节OA患者。这些患者接受了高位胫骨截骨术（HTO）（n = 18）或单髁膝关节置换术（UKA）（n = 22）治疗。临床结局指标包括英国骨科协会（BOA）评分、行走时的疼痛、膝关节被动活动范围（PROM）以及患者的主观意见。步态变量包括自由行走速度、步频、步长以及每条腿的单支撑和双支撑阶段。在手术前以及术后3个月、1年和5年对患者进行检查。步态的时间-距离变量能够在术后3个月检测出治疗效果的差异，而此处给出的临床结局指标未能检测出两组患者之间的任何差异。对于膝关节OA患者，术后临床评估可推荐测量自由行走速度。
