To evaluate the clinical outcomes of an arthroscopic 'L' medial release (ALMR) procedure for the treatment of medial compartment knee osteoarthritis (MCKOA).
Between January 2012 and December 2013, 372 patients with MCKOA of Kellgren's radiographic grade I-III were diagnosed. Among them, 252 patients with MCKOA received ALMR performed by a single surgeon. The other 120 patients received supportive treatment and were regarded as the control group. The Knee Society Score (KSS) at baseline and 2 years, and the subjective visual analogue scale (VAS) at baseline and 1st, 2nd, 6th, 12th, and 24th months were used for outcome studies.
There were 286 patients available for follow-up for more than 2 years and the mean follow-up period was 28 months. There were 202 patients with unilateral MCKOA in the ALMR group and 84 in the control group. The mean subjective VAS showed a statistically significant improvement after 6 months, and then remained relatively stable between the 6th and 24th month. The mean KSS for pain and function improved statistically at 2 years of follow-up.
This ALMR appears to be an effective and safe treatment for mild and moderate MCKOA.
评估关节镜下“L”形内侧松解术（ALMR）治疗膝关节内侧间室骨关节炎（MCKOA）的临床疗效。
2012年1月至2013年12月期间，诊断出372例Kellgren放射学分级为I - III级的MCKOA患者。其中，252例MCKOA患者接受了由单一外科医生实施的ALMR手术。另外120例患者接受支持性治疗，被视为对照组。采用基线及2年时的膝关节协会评分（KSS），以及基线、第1、2、6、12和24个月时的主观视觉模拟量表（VAS）进行疗效研究。
有286例患者获得了超过2年的随访，平均随访期为28个月。ALMR组有202例单侧MCKOA患者，对照组有84例。平均主观VAS在6个月后显示出统计学上的显著改善，然后在第6至24个月之间保持相对稳定。随访2年时，疼痛和功能的平均KSS在统计学上有所改善。
这种ALMR似乎是治疗轻中度MCKOA的一种有效且安全的方法。
