Efficacy Analysis Of Arthroscopic Tenodesis And Comparison Of Two Different Techniques: Detach Or Not Detach The Long Head Of Biceps Tendon

Objective:The purpose of this study is to evaluate operative technique and clinical results of arthroscopic biceps tenodesis for the long head of biceps tendon tendinitis, and we also compared the clinical effect of whether detach proximal tendon or not.Methods:From October 2013 to June 2015, Shanghai No.6 People’s Hospital received orthopaedic diagnosis for biceps tendinitis patients at a total of 40 cases of patients. Those patients were randomly divided into two groups:A group( resection proximal tendon after tenodesis) of 9 males and11 females, age:55.15±7.38; B group(preserve the proximal tendon after tenodesis) of 10 males and10 females, age:53.55±6.19. The main symptoms of patients were shoulder pain which aggravated during abduction. Diagnosis of magnetic resonance imaging(MRI) shows becips tendinitis.All patients were failed to respond to conservative management for about 6 months. All patients were treated by arthroscopic biceps tenodesis with sutureanchor and outer-row anchor through bone. In A group,the long head of biceps tendon has been detached after tenodesis.In B group,the long head of biceps tendon were kept after tenodesis. We’ve used American shoulder and elbow surgeons(ASES),Constant‐Murley shoulder score and the University of California at LosAngeles(UCLA)shoulder score to evaluate the patient’s shoulder pain, function and range of motion at regular follow-up of 3,6,12 months after operation. And also have reviewed the MRI to evaluate the tendon fixation.Results:Postoperative follow-up was carried out for 12 to 20 months(with an average of 14 months).The result of MRI showed well healing of tendon,except one patient in group A,whose fixation failed after 3 monthsof operation. Preoperative ASES score was17.85±4.00, Constant score was 43.05±9.39, UCLA score was 17.00±3.13.The 12 months postoperative score was respectively 33.65±2.23, 87.50±3.14 and 31.60±1.31; In group B,the preoperative ASES score was15.65±6.05,In group B, the preoperative ASES score was 15.65±6.05,Constant score was 39.80±11.21, UCLA score was 16.05±2.48.The 12 months postoperative score was respectively 34.70±2.47,85.20±5.02 and 31.75±2.40; The postoperative functional scores were significantly increased, and there were significant statistical differences(P < 0.05). In the comparison of the treatment effect between two groups respectively at 3 months and 6 months after the operation, Group B score was higher thanA group in UCLA(P < 0.05). In the last follow-up, all the scores have not shown significant difference(P > 0.05).Conclusion:1. For arthroscopic biceps tenodesis with double anchor, a satisfactory efficacy of minimizes trauma and good functional recovery could be received after the treatment of biceps tendinitis.2.Whether resection proximal tendon or not after arthroscopic tenodesis has no significant difference in efficacy.
