Abstract：Objective To assess the impact of sports medicine-based quantitative exercises for patients with arthroscopic surgery for meniscus injuries.Methods Ninety-six patients with meniscus injuries admitted to our department from Jan.2021 to Dec.2023 were prospectively selected for this study.Among them,there were 56 males and 40 females aged 27-68(mean 47.7)years.Seventy-two cases involved the right knee,and 24 the left knee,with 60 lateral and 36 medial meniscus injuries.All patients received arthroscopic treatment.Using a random number table,patients were randomly divided into quantitative exercises group and control group(routine rehabilita-tion exercises)with 48 cases in each group.Patients in the quantitative exercises group were initially graded as ex-cellent,good,fair and poor based on the Lysholm knee score and individualized strength of exercise plans were ar-ranged for each subgroup.The Lysholm knee score,MOS 36-item short form health survey(SF-36),and clinical outcomes were compared between the two groups.Results After 12 weeks of exercises,the Lysholm knee score was significantly higher in the quantitative exercises group than in the control group(80.02±8.94 vs.62.50±7.12,P<0.05).Additionally,the SF-36 scores were also much better in the quantitative exercises group,for all subitems of physical role(78.56±7.13 vs.74.24±6.21),physical function(80.13±6.37 vs.73.46±6.22),emotional role(79.89±8.26 vs.75.83±7.35),daily activities(82.46±7.35 vs.70.12±6.36),mental health(76.29±7.25 vs.68.45±6.29),general health(79.45±7.68 vs.72.15±6.72),social function(79.21±7.75 vs.69.05±6.46)and bodily pain(78.32±7.31 vs.64.70±6.24),all P<0.05.Moreover,the total effective rate was significantly higher in the quantitative exercises group(91.7%vs.75.0%,P<0.05).Conclusion Sports medicine-based quantitative exercises can greatly improve the knee function,quality of life,and clinical efficacy of meniscus injury patients after arthroscopic surgery.
