Summary
Selective knee denervation effectively treats persistent knee pain in 86% of patients when other treatments fail. This procedure significantly improves pain scores and function, offering a viable option for intractable knee conditions.
Area of Science:
- Orthopedic Surgery
- Pain Management
- Regenerative Medicine
Background:
- Persistent knee pain significantly impacts quality of life.
- Traditional treatments often fail for complex knee pain cases.
- Exclusion of structural, infectious, or inflammatory etiologies is crucial.
Purpose of the Study:
- To evaluate the efficacy of selective knee denervation for intractable knee pain.
- To assess patient satisfaction and functional improvement following the procedure.
- To determine the role of selective nerve blocks in patient selection.
Main Methods:
- Retrospective analysis of 70 patients undergoing selective knee denervation.
- Systematic exclusion of other pain sources (e.g., aseptic loosening, arthrosis).
- Successful selective nerve block confirmed prior to denervation.
Main Results:
- 86% of patients reported satisfaction with the denervation procedure.
- Significant improvement in Knee Society scores (mean 51 to 82).
- 70% of patients achieved final Knee Society objective scores above 80.
Conclusions:
- Selective knee denervation is a safe and effective treatment for intractable knee pain.
- The procedure is indicated when conventional methods are exhausted and structural causes are ruled out.
- Successful selective nerve block is a key predictor for positive outcomes.
