Is the lateral femoral condyle weight-bearing?

Is the lateral femoral condyle weight-bearing?

Most cases of osteochondral injury occur in the anterior region, which is the non-weight-bearing portion of the lateral femoral condyle. We describe two patients with osteochondral injury of the weight-bearing surface of the lateral femoral condyle associated with lateral dislocation of the patella.

Is the medial femoral condyle weight-bearing?

OD occurs in the joint cartilage and physis of long bones, as well as in the talus. The medial femoral condyle is the most commonly affected site. OD of the weight-bearing, inferocentral portion of medial femoral condyle is an uncommon, but still challenging issue in knee surgery.

What is the lateral femoral condyle?

There are two femoral condyles. The medial femoral condyle is located on the inside part of the knee whereas the lateral femoral condyle, which is bigger, is located on the outside part of the knee.

What is the function of the lateral femoral condyle?

The larger lateral femoral condyle provides a bony buttress that helps provide lateral patellar stability. The trochlear groove is shallower proximally than distally, indicating that bony stability is compromised as the patella moves superiorly during terminal knee extension.

What is the lateral condyle of the knee?

The lateral condyle is one of the two projections on the lower extremity of the femur. The other one is the medial condyle. The lateral condyle is the more prominent and is broader both in its front-to-back and transverse diameters.

Does a femoral condyle fracture require surgery?

Discussion. Femoral medial condyle fracture is a rare fracture. As with any articular injury, anatomical restoration of the joint surface must be obtained, then lag screw fixation is required.

What is osteochondral defect lateral femoral condyle?

An osteochondral defect, also commonly known as osteochondritis dissecans, of the knee refers to a damage or injury to the smooth articular cartilage surrounding the knee joint and the bone underneath the cartilage.

Where is the lateral condyle?

The lateral condyle is the lateral portion of the upper extremity of tibia. Upper surface of right tibia. (Anterior is at top.) It serves as the insertion for the biceps femoris muscle (small slip).

How long does it take for a fractured femoral condyle to heal?

This normally takes between 6 to 8 weeks but can be up to 14 weeks. During this time, weight-bearing through the injured side can be gradually increased from non-weight-bearing to toe-touch weight bearing to partial weight-bearing, as pain allows.

How do you treat a femoral condyle fracture?

Femoral medial condyle fracture is a rare fracture. As with any articular injury, anatomical restoration of the joint surface must be obtained, then lag screw fixation is required. In fractures with a vertical fracture line, a buttress plate is necessary to counteract the vertical shear forces.

What is a femoral condyle defect?

A chondral defect refers to damage to the articular cartilage located at the end of bones. Specific to the knee joint, damage can occur at the distal end of the femur (thigh bone), the proximal tibia (lower leg bone), or the posterior aspect of the patella (knee cap).

What do 2A and 2B images of the femoral condyle show?

The sagittal (2a) and coronal (2b) images reveal a focal, fluid signal-intensity abnormality (arrows) extending through the articular cartilage of the lateral femoral condyle. Full-thickness cartilage defect at the posterior weight-bearing surface of the lateral femoral condyle.

Is there a cartilage defect in the lateral femoral condyle (Arrow)?

In (8a), the corresponding coronal image, the cartilage defect within the lateral femoral condyle (arrow) is confirmed, though it is less conspicuous. (9a) A fat-suppressed fast spin-echo proton density weighted coronal image reveals an ill-defined cartilage defect (arrow) along the weight-bearing surface of the lateral femoral condyle.

Can fluid-sensitive axial imaging be used to diagnose femoral condylar cartilage defects?

Although radiologists usually rely upon the sagittal and coronal imaging planes for diagnosis of femoral condylar cartilage defects, we have found that fluid-sensitive axial images can actually be quite useful in the detection and characterization of cartilage defects.

What causes fluid in the axial plane of the femoral-tibial joint?

In patients with intact articular cartilage at the femoral-tibial joint, the congruent cartilage surfaces allow only minimal amounts of fluid to collect within the joint itself. In patients with cartilage defects at the joint, fluid typically fills the defect, creating a localized fluid collection that is often visible en face in the axial plane.
