Patellar Fresh Osteochondral Allograft Transplantation
Abstract
Chondral defects of the patellofemoral joint remain a difficult-to-treat pathology with limited long-term results. Currently available techniques to treat large or unipolar chondral defects of the patella include autologous chondrocyte implantation and osteochondral allograft transplantation. Despite the recent advances in orthobiologic adjuncts, there is no single gold-standard surgical approach to this difficult-to-treat pathology in […]
Editorial Commentary: Arthroscopic Outcomes Are Equal to Open Popliteus Tendon Reconstructions, but Do Not Forget That the Goal Is a Stable Posterior Cruciate Ligament Reconstruction
Abstract:
Arthroscopic popliteus tendon reconstructions were found to be equally as efficacious as open popliteus reconstructions in restoring external rotation stability. However, when the procedure was combined with a posterior cruciate ligament (PCL) reconstruction, the PCL reconstruction still had increases of 4 to 5 mm of posterior tibial translation in side-to-side differences on posterior stress radiographs. […]
Influence of Medial Meniscus Bucket-Handle Repair in Setting of Anterior Cruciate Ligament Reconstruction on Tibiofemoral Contact Mechanics: A Biomechanical Study
Purpose:
To compare the impact of an inside-out repair versus meniscectomy of a medial meniscus bucket-handle tear in restoring native contact areas and pressures across the tibial plateaus in the setting of an anterior cruciate ligament (ACL) reconstruction (ACLR).
Methods:
Ten fresh-frozen cadaveric knees were tested in 6 knee conditions (1: intact; 2: ACL torn and bucket-handle […]
Single-Stage Multiple-Ligament Knee Reconstructions for Sports-Related Injuries: Outcomes in 194 Patients
Background:
Outcomes after sports-related multiple-ligament knee reconstructions are limited.
Purpose:
To evaluate outcomes after single-stage surgical treatment of sports-related multiple-ligament knee injuries and to compare outcomes after anterior cruciate ligament (ACL)–based and posterior cruciate ligament (PCL)–based multiple-ligament knee reconstructions.
Study Design:
Case series; Level of evidence, 4.
Methods:
Skeletally mature patients with at least 2 major knee ligaments torn during a […]
Clinical Outcomes of Inside-Out Meniscal Repair According to Anatomic Zone of the Meniscal Tear
Background:
There is significant discrepancy in the reported vascularity within the meniscus, and a progressively diminishing blood supply may indicate a differential healing capacity of tears that is dependent on the affected meniscal zone.
Purpose:
To examine the outcomes after inside-out meniscal repair in all 3 meniscal vascularity zones.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
Patients were included […]
Characterization of Growth Factors, Cytokines, and Chemokines in Bone Marrow Concentrate and Platelet-Rich Plasma: A Prospective Analysis
Background:
Platelet-rich plasma (PRP) and bone marrow concentrate (BMC) are orthobiologic therapies with numerous growth factors and other bioactive molecules. Before the clinical utility of PRP and BMC is optimized as a combined therapy or monotherapy, an improved understanding of the components and respective concentrations is necessary.
Purpose:
To prospectively measure and compare anabolic, anti-inflammatory, and proinflammatory […]
Lateral Posterior Tibial Slope in Male and Female Athletes Sustaining Contact Versus Noncontact Anterior Cruciate Ligament Tears
Background
Lateral posterior tibial slope (PTS) has been identified as a risk factor for primary anterior cruciate ligament (ACL) tears.
Purpose/Hypothesis
The purpose was to prospectively determine if there was a difference in lateral PTS between male and female athletes sustaining contact ACL tears as compared with a group of sex-, age-, […]

LaPrade discusses Blood Flow Therapy (BFR) in ACL Reconstruction Patients
Blood Flow Restriction (BFR) stimulates hypertrophy, increasing the size of muscle cells by reproducing the same kind of environment that’s naturally present when you participate in a high-intensity workout. “The muscle cells can be tricked into believing that they need to hypertrophy due to the extra environmental […]
