Partial Articular Resurfacing Secondary to Pediatric Hip Chondroblastoma Curettage with a 5-YearFollow-Up: A Case Report.

CASE: This report describes a case of pediatric femoral head chondroblastoma, which was initially treated by minimally invasive curettage. At the 18-month follow-up, a subsequent osteochondral defect occurred, which was treated with a partial articular resurfacing system. At 5.5 years follow-up, he was symptom-free with minor degenerative x-ray changes. CONCLUSION: We describe a technique of focal anatomic hip resurfacing using the HemiCAP system in a pediatric chondroblastoma patient who presented with an osteochondral defect after primary curettage. This approach yielded good short-term to midterm results and is a potential alternative to total hip arthroplasty in young patients.
