Purpose
To evaluate femoral head-neck bone regrowth and patient-reported outcomes (PROs) in skeletally immature patients after arthroscopic femoroplasty with minimum 2-year follow-up.
Methods
Eleven hips (10 patients, mean age 14.7 years) with open femoral head physes underwent femoroplasty from 2008 to 2013. PROs (mHHS, NAHS, HOS-SSS, VAS) and radiographs were collected preoperatively, 2 weeks, and minimum 2 years post-op. Alpha angles measured to assess bone morphology changes.
Key Findings
Significant decrease in alpha angle from 61.8° pre-op to 40.7° at 2+ years post-op; no bony regrowth observed. PROs improved significantly: mHHS (58.5 to 79.8), NAHS (56.8 to 87.1), HOS-SSS (34.3 to 78.3), VAS (7.5 to 1.3). Mean satisfaction 8.7/10. One revision arthroscopy (9%) required; no complications.
Conclusions
Arthroscopic femoroplasty in skeletally immature adolescents did not result in femoral head-neck bony regrowth and led to favorable outcomes with high patient satisfaction and no complications.
What Does This Mean For Patients
Young patients undergoing arthroscopic femoroplasty can expect lasting improvement without bone regrowth causing recurrent impingement, making this a safe and effective treatment option.
