Summary
Total hip arthroplasty (THA) and total knee arthroplasty (TKA) improve function, but THA shows better short-term outcomes. Patients reported higher satisfaction and willingness for repeat surgery after THA compared to TKA.
Area of Science:
- Orthopedic surgery
- Arthroplasty outcomes
- Patient-reported outcomes
Background:
- Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common procedures for pain relief and functional improvement.
- Controversy exists regarding whether THA or TKA yields superior patient outcomes.
Purpose of the Study:
- To compare patient outcomes between primary THA and TKA.
- To evaluate willingness for re-operation, WOMAC score changes, expectation fulfillment, and satisfaction levels.
Main Methods:
- Level II prognostic study comparing primary THA and TKA patients.
- Data collected on willingness to have surgery again, WOMAC change scores, expectation fulfillment, and satisfaction.
Main Results:
- Patients undergoing THA reported higher willingness for re-operation (96% vs. 89%) and greater satisfaction (89% vs. 81%) compared to TKA.
- THA group showed greater WOMAC score improvement and more frequently met expectations (78% vs. 70%).
- Higher satisfaction with pain reduction during activities and daily function performance was noted in THA patients.
Conclusions:
- Primary THA demonstrates superior short-term outcomes compared to primary TKA.
- THA may offer greater patient satisfaction and functional recovery in the short term post-surgery.
