Review Meta Analysis
Favourable rotational alignment outcomes in PSI knee arthroplasty: A Level 1 systematic review and meta-analysis.
Implant malposition in total knee arthroplasty (TKA) often results in unsatisfactory outcomes. Rotational malalignment leads to impaired patellar tracking, stability and joint biomechanics. Patient-specific instrumentation aims to improve three-dimensional implant positioning while reducing overall costs of instrumentation. ⋯ 1.
