Articular Cartilage Defects of Knee - Knee & Sports - Orthobullets
2024年12月6日 · Articular cartilage defects of the knee comprise of a spectrum of disease entities from single, focal defects to advanced degenerative disease of articular (hyaline) cartilage. Diagnosis generally requires an MRI to accurately assess the location of specific defects.
Articular Cartilage Lesions of the Knee - Physiopedia
Most articular cartilage defects are caused by trauma, which can either be one single impact injury or repeated micro trauma. A specific group of cartilage damage is "Osteochondritis dissecans", where a well-demarcated small area of cartilage and underlying bone loses its blood supply, dies and eventually fragments and separates into the joint.
The evaluation and management of cartilage lesions affecting the ...
Left untreated, cartilage defects affecting the patella or trochlea alter the normal distribution of weight-bearing forces and may predispose patients to the development of osteoarthritis [1].
Cartilage defects of the femoral trochlea | Knee Surgery, Sports ...
2009年4月28日 · The diagnosis of trochlear cartilage defects is difficult and limited by several factors, including vague symptomatology, confounding pathology in ipsilateral knee structures, and inability to directly palpate the femoral groove.
Chondral Injuries Of The Knee - OrthoPaedia
Patellar dislocation can cause cartilage damage either as the bone goes out of place or when it is reduced (returns to the trochlea). Defects can also be found incidentally on MRI or arthroscopy. If there is no history of acute trauma, the pain usually is described as dull and aching.
Cartilage defects of the femoral trochlea - PubMed
Despite improvements in the ability to detect articular cartilage defects of the trochlea, determining the significance of these lesions remains difficult. Physical examination and history taking remain the best way to estimate the clinical impact of these lesions.
Trochlear Dysplasia | Knee Pain | Minnesota
When the trochlea is flat, or even possibly has a convex or dome shape, it is known as trochlear dysplasia which usually is referred to as an unstable kneecap. In these circumstances, the trochlea is not shaped normally, and the patella does not have the normal bony constraints to provide stability.
Treatment of full thickness cartilage defects in human knees with ...
Our study demonstrated that ACT of the knee provides an excellent treatment for full thickness cartilage defects with outstanding clinical and radiological outcomes. KEYWORDS: Articular Cartilage, Full Thickness Cartilage Defect, Autologus Chondrocyte Transplantation, Knee.
Arthroscopic Treatment of Patellar and Trochlear Cartilage …
Seventeen patients aged 18 to 55 years with symptomatic full-thickness cartilage lesions on either patella or trochlea were treated with matrix autologous chondrocyte implantation (MACI) or microfracture (MF). Both procedures combined with unloading/realigning techniques. Clinical assessment and T2-mapping were evaluated at 48-months.
The trochlear cleft: the “black line” of the trochlear trough
Objective: The “cartilage black line sign” is a recently described T2 dark cartilage lesion that we have identified appearing as a cleft in the trochlear trough. The purpose of our study was to define the MR imaging characteristics of a trochlear cleft, determine its incidence, and correlate the MR findings with arthroscopy.
