Sexual dimorphism and racial diversity render bone –implant mismatch inevitable after off-the-shelf total knee arthroplasty: a systematic review and meta-analysis

ConclusionAnthropometric studies reported considerable sexual dimorphism and racial diversity of femoral geometric ratios. Since a surgeon generally only uses one or a few TKA brands, bone –implant mismatch remains unavoidable in a large proportion of knees. These findings support the drive towards personalized medicine, and accurate bone–implant fit may only be achievable through customisation of implants, though the clinical benefits of custom TKA remain to be confirmed.Level of evidenceIV.
