Clinical Outcomes Of Different Technique For Treatment Of Grade? Bursal-side Partial-thickness Rotator Cuff Tears

Objective: This paper purposed on discussing and evaluating the effect of arthroscopic debridement or arthroscopic repair for treatment of Grade ? bursal-side partial-thickness rotator cuff tears.Methods: 30 cases of Ellman grade ?rotator cuff were retrospective analyzed from January 2016 to June 2017.According to the preoperative conversation and arthroscopic exploration,12 patients underwent debridement and 18 underwent repair.At the time before the operation and 6 months 12 months 24months after the surgery,the visual analog scale(VAS),American shoulder and elbow surgeons scores(ASES),the Constant shoulder score(CSS),University of California at Los Angeles scores(CULA)were used to evaluate and analyze the pain and activity function.Postoperative cuff integrity was determined with MRI following Sugaya's classification.Results: All the 30 patients were followed up for 24 months.Debridement group :VAS scores were improved from(7.25±1.42)before the operation to(2.33±0.49),(0.91±1.08)and(0.50±0.80)at the follow-up 6 months,12 months and 24 months;ASES scores were improved from(30.52±7.76)before the operation to(69.88±4.58)(81.65±7.82)and(87.74±4.59)at the follow-up 6 months,12 months and 24 months;UCLA scores were improved from(12.00±1.60)before the operation to(25.17±1.99)(30.50±1.45)and(32.33±1.15)at the follow-up 6 months,12 months and 24 months;CSS scores were improved from(41.00±9.54)before the operation to(68.17±4.84)(83.25±6.05)and(88.58±2.94);at the follow-up 6 months,12 months and 24 months.Repair group: VAS scores were improved from(7.11±1.32)before the operation to(3.66±1.53)(1.28±0.83)and(0.28±0.46)at the follow-up 6 months,12 months and 24 months;ASES scores were improved from(29.78±10.68)before the operation to(54.50±13.68)(82.10±8.12)and(91.18±3.71)at the follow-up 6 months,12 months and 24 months;UCLA scores were improved from(11.11±1.81)before the operation to(19.44±5.39)(29.33±1.85)and(32.61±1.46)at the follow-up 6 months,12 months and 24 months;CSS scores were improved from(34.94±10.72)before the operation to(53.67±9.26)(81.22±5.95)and(91.00±2.59);at the follow-up 6 months,12 months and 24 months.The differences of the 6 months and 24 months after the operation were significant between the two groups(P<0.05).No significant differences regarding the grade were noted for both surgical techniques at 24 months after the operation.There are significant differences between the pre-operation and after operation in the same group(P<0.05).The retear rates on follow-up MRI were significantly different between the two groups(P<0.05).Conclusion: Arthroscopic debridement or arthroscopic repair technique in the treatment of Grade?bursal-side partial-thickness rotator cuff tears can achieve satisfactory results.The improvement of pain and the recovery of function of the patients in the arthroscopic debridement method were slightly better than that in the repair technique method.The repair group functional score and MRI assessment was slightly better than the debridement group in 24 months after the operation.The treatment of Grade ? bursal-side partialthickness rotator cuff tears advise to arthroscopic repair.
