| Objective: To investigate the postoperative medium-long term efficacy of meniscus allograft transplantation(MAT)and the clinical results of patients’ return to sports(RTS).Methods: 146 patients who underwent MAT surgery from the Sport Medicine of Peking University Hospital from January 2007 to June 2018 were enrolled in this retrospective study.At least two years of clinical follow-ups was conducted.Visual Analog Scores(VAS)and Knee Outcome Injury and Osteoarthritis Score(KOOS)were adopted for preoperative assessment and final follow-up.Preinjury,preoperative evaluation,and the last follow-up were also performed by using Tegner Activity Score.Surgical satisfaction rate and related outcomes(time of RTS,type of sports and reasons for non-RTS and decreased level of sports)were recorded during follow-up.Besides,analyses of factors on return to sports is performed.Results: 103 patients were followed up for an average of 5.70 ± 2.72 years(2-11.5 years),with a follow-up rate of 70.55% and the mean surgical age of of 32.36 ±7.63 years.The patient’s surgical satisfaction rate was 79.6%(82/103).The last follow-up VAS score,KOOS-symptoms,KOOS-pain,KOOS-activities of daily living,KOOS-sports,and KOOS-quality of life scores of the patients were statistically improvement higher than that before surgery(P < 0.001).The Tegner activity scores of the patients at the last follow-up was statistically higher than that before surgery(p > 0.001),whereas lower than that before the injury(p < 0.001).Ninety-two patients participated in sports regularly(more than 2 times/week on average,more than 30 minutes/time)within one year before injury,60.87%(56/92)of patients returned to sports,and the average time to return to sports was 13.98±3.17 months after surgery,of which 39.29%(22/56)returned to the pre-injury sports level and 60.71%(34/56)did not reach the pre-injury level.A total of 36 patients did not return to sports.The principal reasons included worry about secondary injury 55.56%(20/36),no expectation of sports 16.67%(6/36),knee discomfort 27.78%(10/36).And most reasons for the decline in sports level included worry about secondary injury 41.18%(14/34),low sports expectations17.65%(6/34),knee discomfort after sports 23.53%(8/34),and the recommendations of physician for reducing sports intensity 17.65 %(6/34).More than one reason maybe exist.The age variable(p=0.044)may affect the return to sports in the univariate analysis results of this study.Conclusions: The medium-long term efficacy following MAT are satisfactory,which could effectively relieve the knee joint symptoms of patients and improve the activities of daily living and quality of life.60.87% of patients could return to sports and maintain at least one sport,mostly cycling or running.The sports level was significantly higher than before the surgery whereas lower than before the injury.Factors affecting the patients’ sports-returning may be multiple,but the main reason for no sports-returning and the decline of sports levels was the fear of secondary injury. |
