Arthroscopic Biceps Tenodesis Using Interference Screw Fixation in the Bicipital Groove.

Arthroscopic repair of the long head of the biceps (LHB) is performed to treat various biceps pathologies yet the choice between tenotomy or tenodesis remains controversial. Although tenotomy is simpler and quicker, tenodesis results in fewer complications, and there are several techniques available using various fixation devices and sites. This Technical Note describes an all-arthroscopic, suprapectoral tenodesis technique using a bioresorbable interference screw, without motorized devices to create the humeral tunnel in the bicipital groove. The LHB tendon is detached from its glenoid insertion using an arthroscopic cutting instrument or electrocautery. Two portals are created 50 mm distal to the acromioclavicular joint and at 15 mm on either side of the bicipital groove. The arthroscope is introduced through the distal lateral portal till it makes contact with the humerus. The LHB is fastened within its groove using a grasper, reinforced, and then fixed in the humeral tunnel using an interference screw. The present technique is safe, simple, and reproducible. It requires 2 portals in addition to the standard posterior portal and the intra-articular working portal. It minimizes iatrogenic intra-articular damage and thereby limits possible complications. It also limits the intra-articular operative time compared with SLAP repairs.
