Comparison of effect of arthroscopic meniscoplasty and rehabilitation training in the treatment of middle-aged degenerative medial meniscus tear
Objective To compare and analyze the clinical effect of arthroscopic meniscoplasty and rehabilitation therapy on middle-aged patients with simple degenerative medial meniscus tear.Methods Retrospectively analyzed 90 middle-aged patients with medial meniscus tear admitted to Department of Orthopaedic Surgery in Beijing Tiantan Hospital,Capital Medical University from January 2017 to January 2020.According to the different treatment methods selected by the patients,48 patients were divided into meniscus repair group and 42 patients were rehabilitated treatment group.The general condition,KOOS,and knee imaging evaluation(KL)were collected before surgery,3 months and 2 years after surgery,and the clinical effects of the two groups were compared.Results There were no differences in age,sex and body mass index between meniscus repair group and rehabilitation treatment group.There was no difference between the preoperative KOOS score(36.61±7.14 VS 36.7±11.59).The KOOS score(64.3±14.39)in the meniscus group was significantly higher than that in the rehabilitation treatment group(44.65±1.66)3 months after surgery(P<0.05).There was no difference in KOOS score between the meniscus repair group and rehabilitation group(71.2±14.37 VS 72.7±12.15)2 years after surgery.The progress of knee osteoarthritis was significantly obvious in meniscus repair group(3 cases in KL grade 0,24 cases in grade 1,21 cases in grade 2 before surgery;0 cases in grade 0,12 cases in grade 1 and 36 cases in grade 2 in 2 years after surgery)than that in the rehabilitation treatment group(4 cases in grade 0,18 cases in grade 1 and 20 cases in grade 2 before treatment;0 cases in grade 0,16 cases in grade 1 and 26 cases in grade 2 in 2 years after treatment).Conclusion Compared with rehabilitation treatment,meniscus repair can significantly improve the clinical symptoms and knee function,especially pain and daily living ability in the early stage.There is no significant difference in the mid-term clinical follow-up.Meniscus repair accelerates the progression of knee osteoarthritis.Compared with rehabilitation therapy,arthroscopic meniscus repair has no obvious advantage in the treatment of degenerative medial meniscus tear and should be taken with caution.
