Tendon Coverage

Typically, massive rotator cuff tears have stiff and retracted tendon with poor muscle quality, in such cases orthopaedic surgeons are confronted with big challenging to restore the cuff to its native footprint. Furthermore, even with some restoration of the footprint, it is related with a high re-tear rate due to less tension free repair and less tendon coverage. In this tough circumstance, the partial repair has yielded satisfactory outcomes at relatively short follow-up by re-creating the transverse force couple of the rotator cuff. Through this partial repair, the massive rotator cuff tear can be converted to the "functional rotator cuff tear" and provide improvement in pain and functional outcomes in patient's shoulder.

Massive Cuff Tear

Background: Complete repair in massive rotator cuff tear may not be possible, allowing for only partial repair. However, the effect of partial repair on glenohumeral biomechanics has not been evaluated. Therefore, the purpose of this study was to compare the rotational range of motion (ROM), glenohumeral kinematics, and gap formation at the repaired tendon edge following massive cuff tear and repair according to the degree of repair completion. Hypothesis: Posterior fixation will restore the altered biomechanics of massive rotator cuff tear. Study Design: Controlled laboratory study. Methods: Eight cadaveric shoulders were tested at 0°, 30°, and 60° of abduction in the scapular plane. Muscle loading was applied based on physiological muscle cross-sectional area ratios. Maximum internal (MaxIR) and external rotations (MaxER) were measured. Humeral head apex (HHA) position and gap formation at the repaired tendon edge were measured using a MicroScribe from MaxIR to MaxER in 30° increments. Testing was performed for intact, massive cuff tear, complete repair, and 4 types of partial repair. A repeated-measures analysis of variance was used to determine significant differences. Results: Massive tear significantly increased ROM and shifted HHA superiorly in MaxIR at all abduction angles ( P < .05). The complete repair restored ROM to intact ( P < .05), while all partial repairs did not. Abnormal HHA elevation due to massive tear was restored by all repairs ( P < .05). Release of the anterior single row alone and release of the marginal convergence significantly increased gap formation at the anterior tendon edge ( P < .05). Conclusion: This study emphasizes the importance of anterior fixation in massive cuff tear to restore rotational range of motion and decrease gap formation at the repaired tendon edge and of posterior fixation to restore abnormal glenohumeral kinematics due to massive cuff tear. Clinical Relevance: If complete repair of massive cuff tear is not possible, posterior cuff (infraspinatus) repair is necessary to restore abnormal glenohumeral kinematics, and margin convergence anteriorly is recommended to decrease gap formation of the repaired tendon edge, which may provide a better biomechanical environment for healing.

Superior Capsule Reconstruction

Background. The hypothesis of the study was that knowledge about the mechanical properties of biological tissues will help surgeons to choose a transplant. Аim: to determine the optimal type of graft, based on the assessment of the mechanical properties of three types of grafts used for the superior capsule reconstruction of the shoulder joint with massive rotator cuff tear. Methods. In the experimental work, 3 types of biological tissues were studied: allografts fascia lata and dura mater, DX Reinforcement Matrix, Arthrex. The experiment was divided into two parts. In the first part, the mechanical strength at rupture of the samples was evaluated and compared, in the second for resistance to the applied vertical stitch. The type of tests performed included uniaxial stretching. Results. Fascia lata allograft has the maximum tensile strength, and the dura mater allograft has the minimum. All three materials showed a good value of elongation before fracture. The largest value of the maximum force during eruption was recorded for DX Reinforcement Matrix and was 33.5 N. The minimum value was recorded in the fascia lata allograft and is almost 10 N. Conclusion. Fascia lata allograft and DX Reinforcement Matrix, Arthrex have optimal mechanical characteristics and can be recommended as grafts for the superior capsule reconstruction of the shoulder joint with massive rotator cuff tear
