Lateral Patellar Compression Syndrome - Knee & Sports ...
2021年5月29日 · Lateral patellar compression syndrome is the improper tracking of the patella in the trochlear groove generally caused by a tight lateral retinaculum. Diagnosis is made clinically with pain with compression of the patella and moderate lateral facet tenderness and sunrise knee radiographs will often show patellar tilt in the lateral direction.
Patella (Kneecap): Anatomy and Function - Cleveland Clinic
The patella’s medial facet (the side closer to the inside of your body) articulates (moves) with your femur’s medial condyle. The lateral facet (the side closer to the outside of your body) moves with your femur’s lateral condyle.
Diagnosis and Treatment of Lateral Patellar Compression ...
Lateral patellar compression in flexion must be confirmed by clinical examination. Focal tenderness is present at the inferomedial patella and/or the anteromedial joint line. There is no effusion or crepitus, and the patella is stable in both flexion and extension.
The Patella - Surface Anatomy - Functions - Dislocation ...
2023年1月3日 · Lateral facet – articulates with the lateral condyle of the femur. Anterior and posterior surfaces of the patella. The patella has two main functions: Leg extension – Enhances the leverage that the quadriceps tendon can exert on …
Patellofemoral Joint - Physiopedia
The Lateral Patellofemoral Ligament (LPFL) - is an important lateral stabilizer of the patella against medial subluxation or dislocation. Some authors describe the lateral patellofemoral ligament as a palpable thickening of the joint capsule between the patella and femoral epicondyle.
Anatomy, Bony Pelvis and Lower Limb, Knee Patella
2023年10月27日 · Initially, during flexion, the patella's lateral facet is the first surface to make contact with the uppermost part of the lateral femoral condyle. However, when flexed by 30°, the contact surface distributes equally on either side of the patella and femoral condyles.
BIOMECHANICS AND PATHOMECHANICS OF THE PATELLOFEMORAL JOINT
As with the patella, the lateral facet of the femur is larger and extends more proximally to provide a bony buttress to improve patellar stability. A sulcus angle can be identified with radiograph (skyline view) that measures the angle between the lateral and medial femoral condyle (Figure 4).
Patella - Physiopedia
It presents above a smooth, oval, articular area, divided into two facets by a vertical ridge; the ridge corresponds to the groove on the patellar surface of the femur, and the facets to the medial and lateral parts of the same surface; the lateral facet is the broader and deeper.
Arthroscopic Patellar Lateral Facetectomy - PMC
We recommend an arthroscopic lateral patellar facetectomy because the joint can be dynamically assessed, treated, and re-evaluated intraoperatively to ensure that normal bony contact has been restored.
lateral facet of the patella becomes compressed over the lateral femoral condyle. At 90 of flexion, the patella is tight over the lateral femur and not congruent with the trochlea (Fig 2). Pressure produces a concave shape to the lateral facet. These findings cannot be seen from the anterolateral or superomedial arthroscopic portal. Surgical ...
