Surgery treatment of Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture patients under arthroscope: A report of 7 cases and literature review / 吉林大学学报(医学版)

ABSTRACT

Objective: To observe the efficacy of Endobutton combined with the suture in the treatment of Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture, and to explore the characteristics and treatment methods of Meyers-Mckeever-Zaricnyj type IV fracture. Methods: The clinical data of seven patients with Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture were collected; the literature review was performed, and the surgical treatment methods, key points of operation and precautions of the patients were analyzed. Results: After arthroscopic debridement, 3 kinds of main fractures were found anterior cruciate ligament connected fragment (ACLCF), anterior horn of lateral meniscus connected fragment (ALMCF), and posterior-medial cartilage connected fragment (PMCCF). The PMCCF was first fixed after pre-reduction from back to front and from deep to shallow orders, then the ALMCF and ACLCF were fixed, avoiding the secondary displacement and bone cutting. The follow-up periods of 7 patients were 6-12 months, with an average followed-up period of 7 months. The front drawer test (-), Lachman test (-); the average Lysholm score of patients before operation was less than that in the last follow-up period (P<0. 05). The knee joint stability of patients was good, and the knee joint had no movement disorder and infection. Conclusion: The intra-operative reduction order is crucial during the operation of Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture. Perfect fixation can be achieved by using Endobutton combined with suture.
