Massive rotator cuff tear treated with a synthetic patch: a case report 16 years after surgery.

Massive rotator cuff tears usually cannot be repaired due to tendon atrophy and marked retraction, as well as muscles fatty degeneration. There are several options for surgical treatment: open or arthroscopic debridement with or without subacromial decompression, arthroscopic isolated biceps tenotomy, partial tendon repair, use of synthetic or biologic patches, tendon transfers, hemiarthroplasty, reverse arthroplasty, and arthrodesis. In this article, we will discuss a particular case of massive rotator cuff tear treated with Marlex mesh. The patient was clinically, radiologically, and MRI checked 16 years after the surgical implant. The active function of shoulder had preserved very well, the Constant score was 76. The X-rays showed a limited progression of osteoarthritis without further cranial migration of the humeral head. At MR cartilage preservation was appreciated, the patch being in good position and the teres minor being smaller than average but it was nonetheless present. This case report can highlight the usefulness of patches in patients with irreparable rotator cuff lesion both for the immediate benefit in terms of pain, strength, movement, and in perspective allowing for the preservation of anatomical structures that might avoid the need for a prosthetic implant over the years.
