We present the operative technique and clinical results of concomitant reconstruction of the medial collateral ligament (MCL) and the posterior oblique ligament for medial instability of the knee using autogenous semitendinosus tendon with preservation of the tibial attachment. The semitendinosus tendon graft between the screw on the medial epicondyle and the tibial attachment of the graft was ...

Understanding disease of the Cranial Cruciate Ligament The CCL is one of the most important stabilizers of the knee. It prevents hyperextension, limits internal rotation, and prevents the tibia (shin bone) from sliding forward each time the leg bears weight. When the CCL is damaged, the result is an unstable knee. This instability results in pain and inflammation. Over time, debilitating arthri...

Patellar instability is a common finding in patients with below-knee amputation and yet management options are not commonly described in the literature. We describe the first reported case of a medial patellofemoral ligament reconstruction using allograft in a patient with a below-knee amputation. Clinical outcome at two-year follow-up remains very good.

Background: Patellar instability can cause pain and disability. A finite element model of a healthy human knee was performed to analyze the role quadriceps medial retinaculum imbalance in patellar instability. Methods: The created by matching magnetic resonance computed tomography images normal adult patient’s knee. Muscle force intensities were calculated static optimization, considering lower...

Pathologic genu recurvatum is defined by knee hyperextension in excess of 15 degrees and is usually asymmetric. This is a rare disease that can be related to bony, soft tissue or a combination of both. Patients with genu recurvatum commonly present with anterior knee pain, knee instability, ambulation difficulty on uneven ground, and patellofemoral instability. Anterior opening wedge osteotomy ...

And the importance of the conservative treatment...

BACKGROUND Revision total knee arthroplasty (TKA) poses unique challenges compared with primary TKA such as bone loss, deformity, and ligament instability. Modular component options allow flexibility to deal with these complexities. The purpose of this study was to evaluate midterm outcomes for revision TKA using a modular revision knee system with complete interchangeability and multiple optio...

We report an extremely rare case of both recurrent lateral patella dislocation and medial patellofemoral instability, following prior operations to correct patella maltracking. Manual translation of the patella revealed medial and lateral instability with a positive apprehension sign. 3-D computer modelling of kinematics based on MRI data demonstrated that the patella deviated laterally at full...

Introduction Osteoarthritis (OA), also known as degenerative joint disease is the most common form of arthritis and a leading cause of disability worldwide. Osteoarthritis of the knee is one of the five leading cause of physical disability in non-institutionalized elderly men and women. OA knee, along with osteoarthritis of the hip affects the ability to walk and climb stairs more than any othe...
