  1. ^MT = meniscal tear
  2. * SD values at baseline and 6-month follow-up for APM and PT groups estimated using method proposed by Wan et al. [43]
  3. SDd for the difference in KOOS scores for each treatment was estimated using the following equation: \( {SD}_d=\sqrt{\delta_{BL}^2+{\delta}_{6\ months}^2} \)
  4. ** SD estimated from 95% CI where \( {SD}_d=\frac{\left(\sqrt{n}\ast half- width\ of\ 95\% CI\right)}{1.96} \)
  5. *** Only SD (δBL) at baseline given, therefore, the SDd for the difference in VAS scale (0–100) was estimated by the following equation: \( {SD}_d=\sqrt{2{\delta}_{BL}} \)
  6. **** SD given at baseline and follow-up; SDd for difference in KOOS scores for each treatment estimated using the following equation: \( {SD}_d=\sqrt{\delta_{BL}^2+{\delta}_{12\ months}^2} \)
