Improving Clinical Outcomes: Hightibialosteotomy Plate Placement Combined with Arthroscopic Surgery.

ABSTRACT

Objective: Our study aimed to investigate the clinical efficacy of hightibialosteotomy (HTO) posterior plate placement combined with arthroscopic surgery for degenerative injury of the posterior horn of the medial meniscus with poor force lines in the lower extremity, improve joint function or relieve pain. Methods: The case data of 98 patients with osteoarthritis of the knee admitted to the Department of Orthopedics in our hospital from January 2019 to January 2023 were selected for retrospective analysis. The patients were divided into 54 patients, each in the study group and the comparison group according to the different treatment regimens. The study group received hightibialosteotomy plate placement combined with arthroscopic surgery, while the comparison group underwent hightibialosteotomy plate placement alone. The differences in knee scores, knee Lysholm scores, Lysholm scores, Healthcare Security and Safety (HSS) scores, Tegner scores, Visual Analog Scale (VAS), lower extremity force lines, femorotibial angles, and tibial plateau were counted and compared between the two groups. Results: HSS knee function scores, Lysholm scores, and VAS scores of the study group were statistically significant compared with those of the comparison group at the final follow-up of patients, and the postoperative clinical outcomes improved significantly (P < .05). The differences in Hip-Knee-Ankle(HKA) angle andMedial-Pateral Tibial Angle (MPTA) of patients in the study group were statistically significant compared with the comparison group, and the increase in HKA (12.31±2.13)°, MPTA (11.84±2.32)° and lower limb force line was significantly improved (P < .05). Preoperatively, there was no statistically significant comparison between the visual analog scores of the knee joint in the study group and the comparison group. After surgery, the difference between the two groups was statistically significant (P < .05). The relative position of the mechanical axis of the lower limb through the tibial plateau, the femorotibial angle, and the posterior tibial plateau angle increased in patients after surgery, and the differences were statistically significant when compared with the preoperative period (P < .05). Both the tibial posterior displacement distance and the lateral knee gap opening were reduced compared with the preoperative period, and the differences were statistically significant (P < .05). Conclusion: Hightibialosteotomy after plate placement combined with arthroscopic surgery has better clinical efficacy in the early stage and can effectively treat the degenerative injury of the posterior horn of the medial meniscus with poor force lines in the lower limb, improve the joint function, and relieve the symptoms of patients.
