Abstract:
Objective:To investigate the clinical effects of arthroscopic double locking suture combined with single-row suture fixation in the treatment of posterior root tear of the medial meniscus.Methods:A retrospective study was conducted to analyze the clinical data of the patients who had been treated for posterior root tear of the medial meniscus by arthroscopic double locking suture combined with single-row suture fixation from January 2018 to December 2021 at Department of Bone and Joint Surgery, The First Hospital of Wuhan. There were 11 males and 23 females with an age of (55.6±4.0) years. Lysholm subjective function score and Tegner motor function score were used to evaluate the knee function, the Kellgren Lawrence grading of the weight-bearing X-ray film of the affected limb was used to evaluate the osteoarthritis of the affected knee, and MRI was used to evaluate the medial meniscus exostosis.Results:All patients were followed up for 28.0 (26.0, 33.3) months. Their Lysholm subjective function score [90.0 (89.0, 91.0) points] at the last follow-up was significantly higher than the preoperative one [57.5 (55.0, 60.0) points], and their Tegner motor function score at the last follow-up [6.0 (6.0, 6.0) points] significantly better than the preoperative one [4.0 (3.8, 4.0) points] ( P<0.05). The Kellgren Lawrence grading resulted in grade 1 in 8 cases, grade 2 in 24 cases, grade 3 in 2 cases at the last follow-up, comparing with grade 0 in 2 cases, grade 1 in 9 cases, and grade 2 in 23 cases before operation. The medial meniscus exostosis was grade 1 in 8 cases and grade 2 in 26 cases at the last follow-up, comparing with 5 cases of grade 1 and 29 cases of grade 2 before operation. The above comparisons showed no significant difference between the last follow-up and preoperation ( P > 0.05). Conclusion:For patients with posterior root tear of the medial meniscus, arthroscopic double locking suture combined with single-row suture fixation can improve significantly their knee joint function, but can hardly improve their medial meniscus exostosis.
