Summary
Arthroscopic lateral release using electrosurgery effectively treated recurrent patellar instability, reducing pain and improving function. This minimally invasive technique offers results comparable to open surgery with fewer complications.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
Background:
- Recurrent patellar subluxation and dislocation significantly impact patient function.
- Traditional open extensor realignment procedures carry inherent risks.
Observation:
- A review of 39 patients (45 knees) undergoing arthroscopic lateral release with electrosurgery was conducted.
- Follow-up averaged 28 months, assessing outcomes like pain, swelling, and functional ability.
Findings:
- Significant improvements in swelling, instability, and pain were noted post-procedure.
- 85.5% of knees showed improvement or excellent outcomes, though dislocators had poorer results.
- The complication rate was low at 4.4%, with no postoperative hemathroses.
Implications:
- Arthroscopic lateral release with electrosurgery is a viable alternative to open procedures for patellar instability.
- The technique demonstrates comparable efficacy and a favorable safety profile.
- This method is well-documented for managing patellar instability.
