Biological reconstruction of varus deformity in primary total knee replacement using bone graft and description of a new technique

We describe a new technique for correcting large tibial defect by using bone graft, where the uncontained defects were converted to contained defects using bone graft and the contained defect was impacted with cancellous bone. Between 2006 and 2010, 48 cases of primary total knee arthroplasty were reconstructed using autologous bone graft. Of 48 cases, five cases had large tibial defect and were treated with the new technique. Collapse was seen in one knee at 5 months postoperative. The rest of the patients showed improvement in total knee score and limb alignment.We now use this technique to treat large tibial defect during total knee replacement.摘 要脛骨周圍骨缺損可見於膝關節骨關節炎的患者。 在全膝關節置換時必須糾正這些缺陷，以確保假體組件的正確放置和對線。我們描述了一種使用骨移植來糾正大的脛骨缺損的新技術，其中使用骨移植將未包含的缺陷轉換為包含的缺陷，使用鬆質骨衝擊填充包含的缺損。 2006年至2010年間，採用自體骨移植重建48例初次全膝關節置換。 48例中有5例發生大面積脛骨缺損，並採用新技術治療。 術後5個月有一膝關節倒塌。 其餘患者的膝關節評分和肢體對線均有所改善。 我們現在使用這種技術來治療全膝關節置換術中的大的脛骨缺損。
