Arthroscopic Supraspinatus Tendon Reconstruction Using Fascia Lata Autograft Augmentation for Type B and C Musculotendinous Junction Tears

Type B and C musculotendinous junction tears present unique surgical challenges because of poor tissue integrity. We describe an arthroscopic technique-the supraspinatus tendon reinforcement reconstruction technique-that combines autologous fascia lata grafting with remnant tendon augmentation. This biologically optimized approach achieves anatomic restoration through 3 key principles: intramuscular fascia lata passage to enhance medial integration, lateral bridging reinforcement fixation to improve load distribution, and scapular spine anchoring for structural stability. By preserving native kinematics while augmenting repair integrity, this reproducible method may reduce retear rates in type B and C musculotendinous junction tears, offering a viable alternative to traditional reconstructions.
