The importance of the posterolateral corner (PLC) with respect to knee stability, particularly in the setting of anterior cruciate ligament (ACL) deficiency, has become more apparent in recent years. The purposes of this article are to review the current concepts of PLC injuries and to address their role in the ACL-deficient and […]

Satisfactory outcomes have been reported after all-inside meniscus ramp repair with combined anterior cruciate ligament reconstruction (ACLR). […]
Increased posterior tibial slope and posterior medial meniscus root tears increase the force experienced by the anterior cruciate ligament (ACL) and predispose patients to higher rates of primary ACL injury or ACL graft failure after an ACL reconstruction (ACLR). However, the interplay among sagittal plane tibial slope, medial meniscus […]
Medial patellofemoral ligament (MPFL) reconstruction is the treatment of choice for recurrent patellofemoral instability. Although attention to MPFL reconstruction in the orthopaedic literature has increased dramatically in recent years, there is no clear consensus on surgical technique, graft option, or method of fixation. Nevertheless, most studies have shown improved pain scores and low rates […]
Combined posterior cruciate ligament (PCL) and medial collateral ligament (MCL) injuries represent a complex
pathology that requires a thorough clinical and radiographic examination to diagnose and identify all injured structures.
Anatomic reconstruction of the injured ligaments is recommended, including double-bundle PCL reconstruction and
superficial MCL augmentation. In the setting of this complex reconstruction, several technical aspects require […]
Anterolateral rotational instability may persist after anterior cruciate ligament (ACL) reconstruction for a variety of reasons including damage to lateral or posterolateral structures, injury to the meniscus, disruption of anterolateral soft tissue structures, or increased tibial slope. In the setting of revision or primary ACL reconstruction with persistent anterolateral laxity, despite repair or reconstruction […]
Medial meniscal root tears are often disabling injuries that can occur in isolation during low-velocity, deep
knee flexion maneuvers in middle-aged patients. The most common meniscal root tear pattern is a radial tear near the
root attachment (type II). Root tears are often associated with meniscal extrusion, identified on magnetic resonance
imaging. Relocation of the meniscal root […]
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 […]
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. […]
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).
Ten fresh-frozen cadaveric knees were tested in 6 knee conditions (1: intact; 2: ACL torn and bucket-handle […]
