Eight-Year Follow-Up Using a Fresh Osteochondral Allograft for a Femoral Head Chondroblastoma in a 17-Year-Old Patient

Table 1

Reported techniques and outcomes for femoral head chondroblastoma.

Technique	Outcome
Curettage alone
(i) Trapdoor procedure [12]; (ii) Modified trapdoor procedure [13]; (iii) Surgical dislocation [11]	(i) Removal of the lesion; (ii) Risk of impingement between the edges of the surgical defect and the labrum; (iii) Articular surface destruction; (iv) Earlier hip osteoarthritis [8, 9, 24]
Allograft following curettage
(i) Fresh osteochondral allografts [9, 14–16]; (ii) Frozen grafts allografts [17–20]; (iii) Fibular vascularized allograft [21]	(i) Restoration of the articular surface; (ii) Higher risk of infection and potential immunologic reaction [17–20]; (iii) Limited data available using those techniques
Radiofrequency ablation [22, 23]	Efficiency only described in small lesions
Arthroplasty [8, 9, 24]	Total joint replacement

Recurrence rate as high as 20%, this making it imperative to do an aggressive curettage [3].
