Functional outcomes of patient-specific instrumentation versus conventional instrumentation for unicompartmental knee replacement: A systematic review and meta-analysis.
BACKGROUND Patient-specific instrumentation (PSI) has been introduced in unicompartmental knee arthroplasty (UKA) to improve implant positioning and potentially post-operative function. However, its clinical advantage over conventional instrumentation (cUKA) remains uncertain. This study aimed to evaluate current evide...
