Objective: To investigate the role of double-plane high tibial osteotomy in the repair of Posterolateral Complex (PLC) damage with bad lower limb force line.

Methods: A total of 56 cases of patients with PLC injuries who were admitted to our hospital from February 2015 to November 2016 were divided into the study group (n=28) and the control group (n=28) using the random distribution method. The patients in the study group underwent double-plane high tibial osteotomy, whereas the patients in the control group underwent the conventional conservative treatment method. The relative position of the mechanical axis of the lower limb passing through the tibia, the tibial caster angle, the tibial retroposition distance, and the lateral interval opening degree of the patients were compared 1 year postoperative. The postoperative joint function was evaluated using the Lysholm scoring system.

Results: The relative position of the mechanical axis of the lower limb passing through the tibia and the tibial caster angle recovery of the patients in the study group were higher than those of the patients in the control group. By contrast, the tibial retroposition distance and the lateral interval opening degree of the patients in the study group were lower than those of the patients in the control group, and the difference was statistically significant (P<0.05). The Lysholm score of the patients in the study group was significantly higher than that of the patients in the control group, and the difference was statistically significant (χ2=4.9088, P=0.0267).

Conclusion: PLC damage of the knee joint with bad lower limb force line was treated with double-plane high tibial osteotomy. The postoperative effect was satisfactory, and knee function recovery was better compared with that of conventional treatment. Such results are worth popularizing.
