The results after one year or longer were evaluated in 76 patients with extra-articular reconstruction for functionally disabling anterior instability of the knee joint. The reconstruction was performed by a modification of the Ellison procedure for treatment of anterolateral rotatory instability. The various superimposed components of knee instability were managed by a variety of methods. Postoperatively,objective stability correlated well with subjective improvement. Patients with 2+ or greater anterior instability preoperatively had disappointing results in both subjective symptoms and objective signs. although extra-articular reconstruction may be sufficient for lesser grades of functionally disabling instability, knees with grade 2-3+ instability may require direct anterior cruciate ligament reconstruction in addition to the extra-articular surgical procedure.
对76例因膝关节功能性失能性前向不稳而进行关节外重建的患者进行了一年或更长时间后的结果评估。重建采用改良的埃里森手术治疗前外侧旋转不稳。膝关节不稳的各种叠加成分采用多种方法处理。术后，客观稳定性与主观改善情况相关性良好。术前存在2+或更严重前向不稳的患者在主观症状和客观体征方面的结果都不尽人意。尽管关节外重建对于较轻程度的功能性失能性不稳可能足够，但对于2-3+级不稳的膝关节，除关节外手术外，可能还需要直接进行前交叉韧带重建。
