BACKGROUND: The current study was performed to correlate anatomical parameters related to trochlear dysplasia, tibial tuberosity position, and patella alta with in vivo patellar tracking for subjects with recurrent patellar instability. METHODS: Eight subjects with recurrent patellar instability that failed conservative treatment were evaluated using computational reconstruction of in vivo knee motion. Computational models were created from dynamic CT scans of the knee during extension against gravity...

COMPARATIVE STUDY
Dhananjaya Sabat, Atul Jain, Vinod Kumar
PURPOSE: To retrospectively compare the clinical outcomes of displaced tibial-side posterior cruciate ligament (PCL) avulsion fractures treated with open reduction and screw fixation versus arthroscopic suture fixation. METHODS: From 2005 to 2013, all displaced PCL tibial-side avulsion fractures treated surgically-initially by an open posterior approach and later by arthroscopic-assisted suture fixation-were retrospectively reviewed. The cases with radiographic evidence of greater than 3 mm of displacement and/or grade II or III laxity on the posterior drawer test were included in the study group...

BACKGROUND: The treatment of anterior cruciate ligament (ACL) rupture complicated with posterior lateral meniscus root (PLMR) tears remains controversial. The goal of this study was to evaluate clinical outcomes of PLMR tear refixation versus left untreated at the time of reconstruction. MATERIAL/METHODS: From August 2001 to January 2012, 31 patients who undergone repair of PLMR tears were evaluated and compared with a matched control group with untreated PLMR tears...

CONTEXT: The extent of knee extensor and flexor weakness after disruption of knee ligaments affects a rehabilitation output and functional recovery and may give prognostic information on a possible risk of development of knee osteoarthritis. OBJECTIVE: The hypothesis tested was whether patients with a multiple-ligament tear would have larger abnormalities in strength of the knee extensors and flexors than patients with an isolated-ligament rupture. DESIGN: Cross-sectional study, level III...

PURPOSE: Most individuals with an isolated posterior cruciate ligament (PCL) injury do not complain of disability even if posterior instability is objectively revealed by a static physical examination, such as the posterior drawer test. This suggests it is insufficient to only evaluate posterior instability under static conditions. Therefore, we have investigated the effect of isolated PCL injury on the detailed kinematics of the knee in a dynamic environment such as during gait. METHODS: Eight unilateral PCL-deficient males and eight healthy control volunteers participated in this study...

The integrity of posterior cruciate ligament (PCL) is essential for the normal kinematics of the knee. Injury to the PCL has adverse consequences, with worsening of functional performance and an increased risk to develop osteoarthritis. Conservative treatment is sometimes adopted, not only because it is an acceptable option for selected patients but also due to the lack of consensus in the orthopedic literature regarding the best surgical method. Hereby we describe a simplified technique for onlay PCL reconstruction pointing out possible advantages if compared with the traditional transtibial or inlay techniques...

This article discusses athletic injuries of the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and posterolateral corner. Best evidence to date validates that conservative management of ACL ruptures is a reasonable strategy. Current data also seem to advocate nonoperative management of PCL injuries. All isolated MCL injuries, regardless of grade, are usually treated with a brief period of immobilization and symptomatic management. Although the surgical literature often advocates surgical treatment of posterolateral corner injuries, there have been no randomized trials substantiating that these injuries are best treated surgically...

BACKGROUND: Ligaments and cartilage contact contribute to the mechanical constraints in the knee joints. However, the precise influence of these structural components on joint movement, especially when the joint constraints are computed using inverse dynamics solutions, is not clear. METHODS: We present a mechanical characterization of the connections between the infinitesimal twist of the tibia and the femur due to restraining forces in the specific tissue components that are engaged and responsible for such motion...

Injury to the ACL or PCL of the knee most commonly involves a tear of the collagenous fibers of the ligament. Less frequently, a cruciate ligament injury involves an avulsion fracture at the origin or insertion of the ligament, usually from the insertion site on the tibial surface. Avulsion fractures of the cruciate ligaments are important, as they can be identified on radiographs, allowing a specific diagnosis. Although more common in children, when they occur in adults, they are more commonly associated with other injuries...

BACKGROUND: Injuries of the posterior cruciate ligament (PCL) of the knee frequently occur in automobile accidents and sports injuries, although they are less frequent overall than injuries of the anterior cruciate ligament (ACL). Some patients show significant symptoms and subsequent articular deterioration, while others are essentially asymptomatic, maintaining habitual function. Management of PCL injuries remains controversial and prognosis can vary widely. Interventions extend from non-operative (conservative) procedures to reconstruction of the PCL, in the hope that the surgical procedure may have a positive effect in the reduction/prevention of future osteoarthritic changes in the knee...

Surgical treatment of PCL tears is often indicated after conservative management failure and it is known to be challenging with unpredictable outcomes. This study aims to describe and to evaluate the outcome of an arthroscopic PCL anterolateral bundle reconstruction using a quadriceps tendon autograft. Our hypothesis is that knee stability and function can be restored using this technique allowing patients to resume their pre-injury level of activity. Between 2005 and 2008, 21 consecutive patients underwent an isolated PCL reconstruction and were evaluated after a mean follow-up of 29 months (range 12-48)...

BACKGROUND: Dislocation following total knee arthroplasty (TKA) is the worst form of instability. The incidence is from 0.15 to 0.5%. We report six cases of TKA dislocation and analyze the patterns of dislocation and the factors related to each of them. MATERIALS AND METHODS: Six patients with dislocation of knee following TKA are reported. The causes for the dislocations were an imbalance of the flexion gap (n=4), an inadequate selection of implants (n=1), malrotation of components (n=1) leading to incompetence of the extensor mechanism, or rupture of the medial collateral ligament (MCC)...
