Patella resurfacing during total knee arthroplasty is cost-effective and has lower re-operation rates compared to non-resurfacing

Abstract Background The decision to resurface the patella as part of total knee arthroplasty may be influenced by surgeon’s preference, education, training, tradition and geographic location. Advocates for non-resurfacing or selectively resurfacing claim no difference in patient reported outcomes, that is associated with increased risks such extensor mechanism injury malalignment, problems design component technical issues intraoperatively. Aims To critically examine factors should considered addition outcomes process arthroplasty. Method A comprehensive literature search was conducted identify influence making specific outcome measures surgical risks, quality life, procedure cost, re-operation rate, implant design, surgeons learning curve fate remaining cartilage native patellae. Results Patient-reported are equivocal non-resurfacing. Critical analysis available suggests complications historic, which now lower improved technique. Routine cost-effective long term (potential saving £104 per case) has rates revision (absolute risk reduction 4%). Finally, judgment selective prone errors. Conclusion Patella had similar patient-reported outcomes. However, a rate compared
