Summary
Total knee replacement without patellar resurfacing significantly improves knee function and pain scores. Postoperative knee pain relief is not dependent on the severity of patellar degeneration.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee replacement (TKR) is a common procedure for end-stage knee osteoarthritis.
- Patellar resurfacing is a debated component of TKR, with varying outcomes reported.
Purpose of the Study:
- To evaluate the long-term outcomes of total knee replacement performed without patellar resurfacing.
- To determine if the severity of preoperative patellar degeneration impacts postoperative knee pain.
Main Methods:
- A retrospective study of 111 patients who underwent TKR without patellar resurfacing.
- Follow-up ranged from 48.8 to 108.2 months (average 78.2 months).
- Knee Society Clinical Rating System (KS-CRS) was used for evaluation.
Main Results:
- Preoperative mean knee score (34.3) and function score (42.2) improved significantly postoperatively to 91.1 and 89.6, respectively.
- No significant difference in preoperative or postoperative knee pain scores was found across mild, moderate, or severe patellar degeneration groups (p=0.83 and p=0.39).
- None of the patients required secondary patellar resurfacing for pain relief.
Conclusions:
- Total knee replacement without patellar resurfacing yields favorable long-term functional outcomes and pain relief.
- The severity of patellar degeneration does not appear to influence postoperative knee pain in TKR performed without patellar resurfacing.
- Patellar resurfacing may not be necessary for achieving satisfactory pain relief in TKR patients.
