ABSTRACT

Objective To evaluate the operation and review the clinical effectiveness of arthroscopic tenodesis through double-needles positioning approach to treat proximal lesions of Biceps tendon.Methods From January 2010 to January 2013,55 patients (25 men,30 women) with the mean age of 52.4 (range,37-65) years old who underwent arthroscopic tenodesis through double-needles positioning portal to treat proximal lesions of Biceps tendon were retrospectively analyzed.Shoulder pain of all the patients occurred in pre-operation and aggravated at the time of abduction shoulder joint,which affected the normal life for reasons of weakness.Diagnosis of magnetic resonance imaging (MRI) was proximal lesions of Biceps tendon,which was failed to respond to conservative management of six months.All patients underwent biceps tenodesis under arthroscopy with fixation of two suture anchors through bone,and removed tendon stump finally.All the portals of operation and observation of tendon fixation used double-needles positioning portal.We recorded the general condition of shoulder as the level of pain,sphere of activity,active forward flexion and intensity of adduction in pre-operation,3 months,6 months,12 months and 18 months after operation with American Shoulder and Elbow Surgeons (ASES),shoulder function score of Constant-Murley (Constant) and University of California,Los Angeles (UCLA).Then all data were analyzed statistically.Results All patients were operated successfully and got the mean follow-up of 20 months (range,18-24).The result of MRI showed well healing of tendon without rupture.The shoulder function had basically recovered.In pre-operation,ASES,constant and UCLA scores was 10.22±3.02,35.89±7.25,8.53±2.07 respectively.In 18 months after operation,the scores were 32.07± 1.26,89.75±4.07,31.87±2.07 respectively.The outcomes demonstrated that all scores in 18 months after operation had significantly improved,compared to pre-operation.Conclusion The technique of arthroscopic tenodesis through double-needles positioning approach to treat proximal lesions of Biceps tendon is reliable and simple,and can achieve satisfactory clinical outcomes.
