PCL stress radiographs are obtained to objectively determine the amount of increased posterior tibial translation in a patient that may have a possible PCL tear preoperatively and also to determine the postoperative surgical outcomes. PCL stress radiographs can objectively measure the amount of increased posterior tibial translation on the injured knee compared to […]

The posterior cruciate ligament (PCL) is the largest intra-articular ligament in the knee and is the primary stabilizer to posterior tibial translation. Historically, the PCL’s functional dynamics […]
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 […]
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. […]
The diagnosis of incomplete acute and chronic posterior cruciate ligament (PCL) tears can be challenging with conventional magnetic resonance (MR) imaging, particularly for injuries in which the ligament appears continuous as occurs with chronic PCL tears that have scarred in continuity. Quantitative mapping from MR imaging may provide additional useful diagnostic information in these […]
A flattened posterior tibial slope may cause excessive unwanted stress on the posterior cruciate ligament (PCL) reconstruction graft and place patients at risk for PCL reconstruction graft failure. To date, there is a paucity of biomechanical studies evaluating the effect of posterior tibial slope on the loading properties of single-bundle (SB) and double-bundle (DB) […]
Recent clinical studies identified sagittal plane posterior tibial slope as a risk factor for increased postoperative lax- ity after single-bundle posterior cruciate ligament reconstruction (PCLR).
To retrospectively compare the degree of posterior tibial slope and its effect on posterior tibial translation (PTT) after double-bundle (DB) PCLR. Our null hypothesis was […]
Recent biomechanical studies have identified sagittal plane posterior tibial slope as a potential risk factor for pos- terior cruciate ligament (PCL) injury because of its effects on the kinematics of the native and surgically treated knee. However, the literature lacks clinical correlation between primary PCL injuries and decreased posterior […]
The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography […]
Purpose: To determine the epidemiology by player position, examination, imaging findings, and associated injuries of posterior cruciate ligament (PCL) injuries in players participating in the National Football League (NFL) Combine.
Methods: All PCL injuries identified at the NFL Combine (2009-2015) were reviewed. Data were obtained from the database organized by […]
