Depressed tibial plateau fractures in 13 patients were treated under arthroscopic control. In 3 patients, bone autograft was used; in the remaining 10, hydroxyapatite (HAP) grafts were used. The depression of the articular surface was managed by elevation of the subchondral plate through a small window. Assisted by fluoroscopy, we corrected and performed the grafting under arthroscopic control. Follow-up periods averaged 5 years 6 months for the autograft and 18 months for the HAP grafts. At the conclusion of the follow-up period, x-ray radiographs and computed tomography (CT) scan showed no evidence of arthrosis and knee motion was normal. There were no significant differences between the two groups. The interporous spaces showed new bone formation on closed biopsy 6 months postoperatively.
13例胫骨平台凹陷骨折患者在关节镜控制下接受治疗。其中3例使用自体骨移植；其余10例使用羟基磷灰石（HAP）移植。通过一个小窗口抬起软骨下骨板来处理关节面的凹陷。在荧光透视辅助下，我们在关节镜控制下进行矫正和移植。自体骨移植组的随访期平均为5年6个月，HAP移植组为18个月。随访期结束时，X线平片和计算机断层扫描（CT）显示无关节病迹象，膝关节活动正常。两组之间无显著差异。术后6个月的闭合活检显示骨小梁间隙有新骨形成。
