Summary
This study found no clinical benefit of patellar resurfacing during total knee replacement (TKR). Outcomes for TKR with or without patellar resurfacing were similar in osteoarthritic knees.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Osteoarthritis commonly affects the knee joint, necessitating surgical intervention like total knee replacement (TKR).
- Patellar resurfacing is a debated component of TKR, with unclear benefits for clinical outcomes.
Purpose of the Study:
- To compare the clinical outcomes of total knee replacement (TKR) with and without patellar resurfacing.
- To evaluate the impact of patellar resurfacing on anterior knee pain and functional improvement.
Main Methods:
- A prospective, randomized study involving 142 patients (181 osteoarthritic knees) undergoing TKR with the Profix system.
- Annual blinded evaluations by an independent observer using validated scales (knee pain, Knee Society system) and specific functional tests.
Main Results:
- No significant difference in overall clinical outcomes between TKR with and without patellar resurfacing.
- Anterior knee pain occurred in 30.1% of knees with resurfacing versus 20.9% without (p=0.183).
- No patellofemoral joint-related revisions were required in either group.
Conclusions:
- Patellar resurfacing does not offer a demonstrable clinical advantage in TKR for osteoarthritis.
- Further investigation may be warranted for specific patient subgroups experiencing anterior knee pain post-TKR.
