Anatomic acromioclavicular and Coracoclavicular ligament reconstruction with allograft is effective for the management of non-acute acromioclavicular dislocations.

Objective: to analyze the short-term outcomes of an anatomical technique that reconstructs both the acromioclavicular and coracoclavicular ligaments with the help of a tendon allograft for the management of non-acute acromioclavicular dislocations.

Methods: this is a prospective longitudinal study of a case series of subjects with symptomatic non-acute (>3 weeks) acromioclavicular dislocations surgically managed with an anatomical reconstruction of both the acromioclavicular and coracoclavicular ligaments using tibial tendon allografts. Outcomes were assessed with simple standardized radiographs and with the Constant-Murley, American Shoulder and Elbow Surgeons (ASES)-shoulder and Quick-DASH (Disabilities of the Arm, Shoulder and Hand) scales; also, the acromioclavicular joint stability and the scapulothoracic kinematics were assessed.

Augmentation of a Transosseous-Equivalent Repair in Posterosuperior Nonacute Rotator Cuff Tears With a Bioinductive Collagen Implant Decreases the Retear Rate at 1 Year: A Randomized Controlled Trial.

Purpose: To determine whether the addition of a bioinductive collagen implant (BCI) over a transosseous equivalent (TOE) repair of medium-to-large posterosuperior rotator cuff tears improves the healing rate determined by magnetic resonance imaging (MRI) at 12-month follow-up.

Methods: A Level I randomized controlled trial was performed in 124 subjects with isolated, symptomatic, reparable, full-thickness, medium-to-large posterosuperior nonacute rotator cuff tears, with fatty infiltration ≤2. These were randomized to 2 groups in which an arthroscopic posterosuperior rotator cuff tear TOE repair was performed alone (Control group) or with BCI applied over the TOE repair (BCI group).
