Patient-Reported Outcomes Following Medial Patellofemoral Reconstruction With Peroneus Longus Allografts Demonstrate Good Results.

Purpose: To evaluate the recurrent dislocation risk and patient-reported outcomes of peroneus longus allograft tissue for medial patellofemoral ligament (MPFL) reconstruction.

Methods: Patients who underwent MPFL reconstruction with peroneus longus allograft at an academic center between 2008 and 2016 were identified. Record review and patient contact were used to identify any cases of recurrent patellar dislocation and collect patient-reported outcomes scores (Knee injury and Osteoarthritis Outcome Score [KOOS], Norwich Patellar Instability score, Marx activity scale).

Medial patellofemoral ligament reconstruction with allograft versus autograft tissue results in similar recurrent dislocation risk and patient-reported outcomes.

Purpose: To determine the rate of recurrent dislocation and patellar instability following medial patellofemoral ligament (MPFL) reconstruction with allograft or autograft tissue and compare patient-reported outcomes for patients undergoing allograft and autograft MPFL reconstruction.

Methods: One hundred and fifteen MPFL reconstructions (78 allograft, 37 autograft) without concurrent bony procedures performed between 2008 and 2014 by four sports medicine fellowship-trained orthopedic surgeons at our center were identified. Patient demographics and surgical data were identified by chart review.

Immune modulation with primed mesenchymal stem cells delivered via biodegradable scaffold to repair an Achilles tendon segmental defect.

Tendon healing is a complex coordinated series of events resulting in protracted recovery, limited regeneration, and scar formation. Mesenchymal stem cell (MSC) therapy has shown promise as a new technology to enhance soft tissue and bone healing. A challenge with MSC therapy involves the ability to consistently control the inflammatory response and subsequent healing.
