Patient-Specific or Conventional Instrumentations: A Meta-analysis of Randomized Controlled Trials

Figure 6

Forest plot of patient-reported outcomes, complications, and length of stay. (a) Forest plot of patient-reported outcomes: (A) Knee Society Score (KSS), subgroup analysis by KSS-knee and KSS-function. (B) Oxford Knee Society (OKS). (b) Forest plot of complications between PSI and CI. (c) Forest plot of length of stay in hospital (days) between PSI and CI. SD: standard difference; PSI: patient-specific instrumentation; CI: conventional instrumentation.
