Total knee arthroplasty (TKA) without soft tissue balance can create a balanced knee to a mechanical axis of near neutral with bone cuts, and remove osteophytes thoroughly. In this study, the authors present detailed steps for performing TKA. The attached video demonstrates the TKA procedure. The patient is a 77-year-old man who had suffered from knee pain for 12 years. Physical examination showed the Apley test to be positive and that the range of motion (ROM) decreased. An X-ray filmed at the positive lateral of the knee joint and the double lower extremity revealed a progression of degenerative osteoarthritis with genu varum. The key point of no soft tissue release is to make a rectangular extensional space by osteotomy. In addition, the osteophytes, especially syndesmophytes, should be removed thoroughly. As a result, the ligaments can achieve ideal length and the flexion contracture can also be remedied. Moreover, in surgeries without soft tissue release, bone mass and normal tissue are retained. Patients are satisfied to the surgery not only with less blood loss, anterior knee pain and DVT, but also faster rehabilitation. In summary, TKA without soft tissue balance is an efficient procedure for patients with knee osteoarthritis which can result in good prognosis.
不进行软组织平衡的全膝关节置换术(TKA)可通过截骨使膝关节在机械轴上接近中立位达到平衡,并彻底清除骨赘。在本研究中,作者介绍了进行TKA的详细步骤。所附视频展示了TKA手术过程。患者为一名77岁男性,膝关节疼痛12年。体格检查显示阿普利试验阳性,活动范围(ROM)减小。膝关节正侧位X线片及双下肢X线片显示退行性骨关节炎伴膝内翻进展。不进行软组织松解的关键在于通过截骨形成一个矩形伸展空间。此外,应彻底清除骨赘,尤其是韧带骨赘。这样,韧带可达到理想长度,屈曲挛缩也可得到纠正。而且,在不进行软组织松解的手术中,骨量和正常组织得以保留。患者对该手术满意,不仅失血少、无前膝疼痛和深静脉血栓形成,而且康复更快。总之,不进行软组织平衡的TKA对膝关节骨关节炎患者是一种有效的手术方法,可带来良好预后。
