Summary
Radiofrequency capsular shrinkage shows poor results for voluntary shoulder instability, especially in patients with prior surgery. Repeat procedures may improve outcomes in some cases.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
Background:
- Voluntary shoulder instability often persists despite physiotherapy.
- Involuntary instability remains a challenge in managing shoulder joint laxity.
Purpose of the Study:
- To evaluate the efficacy of radiofrequency capsular shrinkage for treating voluntary shoulder instability.
- To assess outcomes based on prior surgical history and the potential for repeat procedures.
Main Methods:
- Prospective study of 13 consecutive shoulders treated with radiofrequency capsular shrinkage.
- Follow-up averaged 45 months, with results assessed using the Rowe rating system.
Main Results:
- Overall poor results (69.2%) according to the Rowe system.
- All patients with previous stabilization surgery experienced recurrent instability.
- Repeat capsular shrinkage improved outcomes in 50% of eligible cases (2 out of 4).
Conclusions:
- Radiofrequency capsular shrinkage yields poor outcomes for voluntary shoulder instability.
- Repeat procedures may offer some benefit, but it is not recommended for patients with prior stabilization surgery.
