  • 「A total of 180 patients with osteoarthritis of the knee were randomly assigned to receive arthroscopic débridement, arthroscopic lavage, or placebo surgery. Patients in the placebo group received skin incisions and underwent a simulated débridement without insertion of the arthroscope. Patients and assessors of outcome were blinded to the treatment-group assignment.」
  • 「At no point did either of the intervention groups report less pain or better function than the placebo group.」
  • 「mean (+/-SD) scores on the Knee-Specific Pain Scale (range, 0 to 100, with higher scores indicating more severe pain) were similar in the placebo, lavage, and débridement groups: 48.9+/-21.9, 54.8+/-19.8, and 51.7+/-22.4, respectively, at one year」
  • 背景句「Many patients report symptomatic relief after undergoing arthroscopy of the knee for osteoarthritis」，对应收益栏末句「很多人术后确实觉得好了」。

  • 「patients with moderate-to-severe osteoarthritis of the knee. Patients were randomly assigned to surgical lavage and arthroscopic débridement together with optimized physical and medical therapy or to treatment with physical and medical therapy alone.」
  • 「Of the 92 patients assigned to surgery … Of the 86 patients assigned to control treatment」→ 共 178 人。
  • 「WOMAC score (range, 0 to 2400; higher scores indicate more severe symptoms)」「After 2 years, the mean (+/-SD) WOMAC score for the surgery group was 874+/-624, as compared with 897+/-583 for the control group (absolute difference … -23+/-605; 95% confidence interval [CI], -208 to 161; P=0.22 …)」
  • 摘要未写国别，正文不写国家（Moseley 2002 同理）。

  • 「randomized, double-blind, sham-controlled trial in 146 patients 35 to 65 years of age who had knee symptoms consistent with a degenerative medial meniscus tear and no knee osteoarthritis」
  • 「there were no significant between-group differences in the change from baseline to 12 months in any primary outcome」
  • 「score for knee pain after exercise, 3.1 and 3.3 points, respectively (between-group difference, -0.1; 95% CI, -0.9 to 0.7)」，量表「rated on a scale from 0 to 10」。

  • 「The search identified nine trials assessing the benefits of knee arthroscopic surgery in middle aged and older patients」
  • 「interventions including arthroscopy showed a small benefit of 3-5 mm for pain at three and six months but not later up to 24 months. No significant benefit on physical function was found (effect size 0.09, -0.05 to 0.24).」（3–5 mm 指 0–100 mm 视觉评分，正文写成「0 到 100 分」）
  • 「Harms included symptomatic deep venous thrombosis (4.13 (95% confidence interval 1.78 to 9.60) events per 1000 procedures), pulmonary embolism, infection, and death.」

https://doi.org/10.1136/bmj.j1982，全文 https://europepmc.org/article/PMC/PMC5426368

  • 「We make a strong recommendation against the use of arthroscopy in nearly all patients with degenerative knee disease」
  • 适用人群：「knee pain, particularly if they are >35 years old, with or without: Imaging evidence of osteoarthritis Meniscus tears Locking, clicking, or other mechanical symptoms except persistent objective locked knee Acute or subacute onset of symptoms」
  • 机械症状的例外：「the evidence applies to patients with any severity of mechanical symptoms, with the only possible exception being those who are objectively unable to fully extend their knee (that is, a true locked knee).」
  • 外伤与年轻人：「The term degenerative knee disease does not include patients having recent debut of their symptoms after a major knee trauma with acute onset of joint swelling (such as haemarthrosis)」；「We did not consider young patients with sports related injuries or patients with major trauma in any age.」
  • 恢复期：「It takes between two and six weeks to recover from arthroscopy」
  • 换关节：「Knee replacement is the only definitive therapy, but it is reserved for patients with severe disease after non-operative management has been unsuccessful.」
  • 人群标签写 35岁，依据上面「>35 years old」。

  • 「140 adults, mean age 49.5 years (range 35.7-59.9), with degenerative medial meniscal tear」「12 week supervised exercise therapy alone or arthroscopic partial meniscectomy alone」
  • 「No clinically relevant difference was found between the two groups in change in KOOS4 at two years (0.9 points, 95% confidence interval -4.3 to 6.1; P=0.72). At three months, muscle strength had improved in the exercise group (P≤0.004).」

  • 「High-quality evidence from 44 trials (3537 participants) indicates that exercise reduced pain … Pain was estimated at 44 points on a 0 to 100-point scale … exercise reduced pain by an equivalent of 12 points (95% CI 10 to 15 points).」
  • 「These studies indicated sustainability of treatment effect for pain (SMD -0.24 …), with an equivalent reduction of 6 (3 to 9) points」（停练后两到六个月）

  • 「Participants were 454 overweight and obese older community-dwelling adults (age ≥55 years with body mass index of 27-41) with pain and radiographic knee OA.」
  • 「Mean weight loss for diet + exercise participants was 10.6 kg (11.4%)」

等级与量级

  • 证据等级 A：三项随机试验（两项假手术对照）、一篇荟萃、一篇 GRADE 指南，替代做法有 Cochrane 高质量证据。标「争议」是因为国内 2018 年版指南对带机械症状的人仍持肯定态度，Thorlund 也看到 3 到 6 个月的小好处。
  • 收益量级「中」，口径金钱：凭判断。国内膝关节镜手术费用没找到官方公布数字，不能按金额阈值机械套。省下的是手术费、2 到 6 周恢复期，并避开血栓（约千分之四）等少见害处。
  • 同轮把本节第 5 条（氨糖）备注末句的「见第 2 节」改成「见本节第 33 条（关节镜清理）」：第 2 节里没有讲膝关节的条目，原指路落空。
