Risk factors for the postoperative effect of symptomatic discoid lateral meniscus after arthroscopy / 中国骨伤

ABSTRACT

OBJECTIVE@#To explore the influencing factors of the postoperative effect of arthroscopic treatment of symptomatic discoid lateral meniscus (DLM).@*METHODS@#From September 2008 to September 2015, patients with symptomatic DLM treated by arthroscopic surgery were retrospectively analyzed. The knee function was evaluated by Lysholm scoring system. According to the scoring results, it was divided into excellent (≥90 points), good (80 to 89 points), fair (70 to 79 points) and poor (<70 points). Sixteen research factors were collected, namely gender, operation age, body mass index, work intensity, symptom duration, history of knee injury, involved knee side, DLM classification, DLM injury type, DLM injury site, medial meniscus injury, knee cartilage injury site and degree, Kellgren-Lawrence (K-L) classification, operation method, and latest follow-up time. According to the data type, Kruskall-Wallis rank sum test or @*RESULTS@#According to the inclusion and exclusion criteria, 502 patients were included. Lysholm functional grade at the latest follow-up was higher than that before operation (@*CONCLUSION@#Arthroscopy is a safe and effective method for the treatment of symptomatic DLM. The gender, body mass index, work intensity, age of operation, duration of symptoms and degree of knee cartilage injury are independent influencing factors for the postoperative efficacy of symptomatic DLM.
