Modified suture-bridge technique to prevent a marginal dog-ear deformity improves structural integrity after rotator cuff repair.
The arthroscopic suture-bridge technique has proved to provide biomechanically firm fixation of the torn rotator cuff to the tuberosity by increasing the footprint contact area and pressure. However, a marginal dog-ear deformity is encountered not infrequently when this technique is used, impeding full restoration of the torn cuff. ⋯ A modified suture-bridge technique to prevent a marginal dog-ear deformity provided better structural outcomes than a conventional suture-bridge technique for medium-sized to massive rotator cuff tears. This technique may ultimately provide better functional outcomes by decreasing the retear rate.

Few surgeons use a contralateral patellar tendon autograft for primary anterior cruciate ligament (ACL) reconstruction because of concern for donor site morbidity. ⋯ After ACL reconstruction with contralateral patellar tendon graft, patients can achieve strength symmetry between legs after surgery without experiencing adverse subjective symptoms after graft harvest. Furthermore, strength return can be superior with a contralateral graft than with an ipsilateral graft.

Rotational knee stability provided by the anterior cruciate ligament (ACL) in the pivot-shift phenomena involves analysis of more complex robotic testing profiles and resulting tibiofemoral compartment kinematics and subluxations. ⋯ Surgeons should be cautious in interpreting conclusions on ACL function and graft reconstructions without knowing the resulting tibiofemoral subluxations or loading conditions that may limit maximum anterior tibial femoral subluxations.
