Study on the influence of inflatable tourniquet on postoperative rehabilitation of meniscoplasty and suture surgery under arthroscopy / 中国医学装备

ABSTRACT

Objective:To investigate the influence of using tourniquet on the postoperative pain,the muscle injury,the meniscal healing and the rehabilitation of meniscus function after surgery of meniscus suture and repair under arthroscopy.Methods:A total of 144 patients who underwent surgery of suture and repair for meniscus of knee joint in hospital were selected and they were divided into tourniquet group(81 cases)and non-tourniquet group(63 cases)according to whether used tourniquet.Postoperative muscle injury was assessed according to postoperative serum creatine kinase(CK),and postoperative pain was assessed by using visual analogue scale(VAS).The international k nee documentation committee(IKDC)scoring system,Lysholm knee joint score and Tegner knee joint score system were used to assess the rehabilitation effect of the function of knee joint of patient after surgery,and the clinical healing after the surgery of meniscus suture was evaluated according to Barrett standard.Results:There were no significant differences in CK levels between the two groups before surgery,2 days and 8 days after surgery,and at the last follow-up(t=1.667,t=-2.143,t=-4.461,t=-6.380,P>0.05),respectively.There were no significant differences in VAS scores between the two groups before surgery,2 days and 8 days after surgery,and at the last follow-up(Z=-1.121,Z=-1.364,Z=0.745,Z=-0.894,P>0.05),respectively.There were no significant differences in IKDC scores and Lysholm scores before and after surgery between the two groups(tIKDC=-1.680,t=0.533,tLysholm=-3.162,t=-2.543,P>0.05),respectively.There were no significant differences in Tegner score before and after operation between the two groups(Z=-0.803,Z=-0.370,P>0.05),respectively.There was no significant difference in the healing rate of meniscus after surgery between the two groups(Z=-0.247,P>0.05).Conclusion:The use of tourniquet in the surgery of meniscus suture under arthroscopy would not cause muscle injury,and would not aggravate pain,and does not affect healing rate and rehabilitation of meniscus function of patients.
