AB  - BACKGROUND: Total knee arthroplasty (TKA) is effective in relieving pain and 
      improving function in patients with end-stage knee osteoarthritis. Both medial 
      stabilized total knee arthroplasty (MS-TKA) and posterior stabilized total knee 
      arthroplasty (PS-TKA) can achieve satisfactory clinical results, but comparisons 
      between MS-TKA and PS-TKA have yielded contradictory conclusions. This systematic 
      review and meta-analysis were performed to investigate the differences in 
      clinical and patient-reported outcomes (PROMs) between MS-TKA and PS-TKA. 
      METHODS: In December 2020, systematic searches of the following databases were 
      undertaken: Pubmed, Embase, Cochrane Library, Clinical Trials.gov. Studies with 
      PROMs comparing MS-TKA to PS-TKA were included. Meta-analysis was conducted for 
      range of motion (ROM), Knee Society Score (KSS), Knee Society Functional Score 
      (KFS), Forgotten Joint Score (FJS), Western Ontario and McMaster Universities 
      Osteoarthritis Index (WOMAC), and Oxford Knee Score (OKS). RESULTS: There were 17 
      studies included in this review, 13 studies used for quantitative analysis, and 4 
      studies used for qualitative synthesis. Meta-analysis concluded that the WOMAC 
      mean difference (MD) for MS-TKA was 1.55 higher than for PS-TKA (MD = -1.55; 
      95 %CI = -2.45 to -0.64, P = 0.0008); however, this difference was less than the 
      minimum clinically important difference (MCID) value of 15. Assessment using the 
      OKS determined that the MD for PS-TKA was 0.58 higher than for MS-TKA (MD = 0.58; 
      95 %CI = 0.25 to 0.91, P = 0.0006); again, this MD was less than the MCID value 
      of 5. There were no significant differences between MS-TKA and PS-TKA when 
      assessed by ROM (P = 0.23), KSS (P = 0.13), KFS (P = 0.61), or FJS (P = 0.22). 
      CONCLUSION: Derived from numerous sources, utilizing a multitude of validated 
      functional and patient-reported outcome assessment tools, there was no clinically 
      evident advantage of MS-TKA compared to PS-TKA. REGISTRATION: The registration 
      number on PROSPERO is CRD42021228555.
