Background
The potential for bony regrowth after femoroplasty in skeletally immature patients is a concern. This study evaluates radiographic and clinical outcomes in adolescent patients.
Methods
11 hips (10 patients, mean age 14.7 years) with open physes underwent arthroscopic femoroplasty. Alpha angles measured pre-op, at 2 weeks, and at minimum 2 years. Clinical outcomes via mHHS, NAHS, HOS-SSS, VAS.
Key Findings
- No bony regrowth observed over 2 years.
- Alpha angle reduced from 61.8° to 40.7°.
- Significant improvements in all PROs and VAS scores.
- One patient required revision; no complications reported.
Conclusions
Arthroscopic femoroplasty in adolescents with open growth plates does not result in bony regrowth and offers significant symptom relief and functional improvement.
What Does This Mean for Providers?
- Arthroscopic femoroplasty is safe and effective in carefully selected skeletally immature patients.
- Concerns about bony regrowth may be overstated in this population.
- Close follow-up remains essential, but this technique can be a valid alternative to delay or avoid open procedures.
