Summary
Deciding whether to resurface the patella during total knee arthroplasty (TKA) is complex. Current evidence is limited, with potential benefits and risks for patellar resurfacing needing further research for optimal patient selection.
Area of Science:
- Orthopaedic Surgery
- Biomedical Engineering
Background:
- Patellar resurfacing during total knee arthroplasty (TKA) is debated, with no consensus on optimal outcomes.
- Potential benefits include avoiding anterior knee pain and reoperations, but risks include implant loosening, fracture, and instability.
Purpose of the Study:
- To review current literature on patellar resurfacing in TKA.
- To evaluate evidence for and against the procedure.
- To identify patient and surgical factors influencing outcomes and decision-making.
Main Methods:
- Literature review of studies on patellar resurfacing in TKA.
- Analysis of factors such as weight, BMI, chondromalacia, and alignment.
- Assessment of surgical decision-making guidelines.
Main Results:
- Evidence for and against patellar resurfacing is presented.
- Patient-specific and surgical factors may influence functional outcomes.
- Clear guidelines for surgical decision-making are currently lacking.
Conclusions:
- Further research is needed to determine the most appropriate candidates for patellar resurfacing.
- Individualized patient assessment is crucial for surgical decision-making in TKA.
- Optimizing outcomes requires a better understanding of factors influencing patellar resurfacing success.
