Open-wedge high tibial osteotomy (OW-HTO) is an effective surgical intervention for medial-compartment knee osteoarthritis. However, the osteotomized gap might be a disadvantage in OW-HTO because it can cause problems such as delayed bone union or loss of correction. These issues can be minimized by using autologous bone graft in the osteotomized gap, which is known to be the fastest and most clinically satisfactory gap filler. The primary mechanical stability of the osteotomy site in OW-HTO is essential for early weight bearing after surgery. Therefore, we introduce the combination of a cylindrical autologous bone grafting technique and a metallic block insertion for faster bone union and better primary stability of the site in OW-HTO. We expect that the described procedure will enable early postoperative weight bearing and, thereby, allow an early return to normal function.
开放楔形高位胫骨截骨术（OW-HTO）是治疗膝关节内侧间室骨关节炎的一种有效手术干预方法。然而，截骨间隙在OW-HTO中可能是一个不利因素，因为它可能导致诸如骨愈合延迟或矫正丢失等问题。通过在截骨间隙使用自体骨移植可以将这些问题降至最低，自体骨移植是已知最快且临床上最令人满意的间隙填充材料。OW-HTO中截骨部位的初始机械稳定性对于术后早期负重至关重要。因此，我们介绍一种圆柱形自体骨移植技术与金属块植入相结合的方法，以实现OW-HTO中更快的骨愈合和更好的截骨部位初始稳定性。我们期望所描述的手术方法能够实现术后早期负重，从而使患者早日恢复正常功能。
