Purpose
To determine if the cam lesion recurs after femoral neck osteoplasty for femoroacetabular impingement (FAI) and assess patient outcomes at two years.
Methods
A prospective study of 47 patients who underwent hip arthroscopy with femoral neck osteoplasty. Alpha angle and femoral offset were measured preoperatively, 2 weeks postoperatively, and at 2 years. Patient-reported outcome scores were also collected.
Key Findings
- Alpha angle significantly decreased after surgery and remained stable at two years, indicating no cam regrowth.
- Femoral offset increased postoperatively and remained stable.
- Patient outcomes improved significantly at 3 months and were maintained or further improved at two years.
Conclusion
No evidence of cam lesion regrowth was observed two years after surgery, and patient outcomes improved and were sustained.
What This Means for Patients
Patients undergoing cam osteoplasty can expect durable correction of the deformity without recurrence, along with lasting improvement in symptoms and function.
