Part of the advantage of using the 3-D model is that the material was similar to bone, so I could determine whether I had to make certain cuts or adjust the angle to shape the trochlea the way I wanted.
The acquired condition can result from trauma or inflammation in the region of the trochlea.
CT scanning is helpful to indicate the size of the donor site and its extension into the trochlea.
These lesions were drilled in 49 medial femoral condyle lesions, 9 lateral femoral condyle lesions, 7 trochlea lesions, and 9 patella lesions.
In full extension, the patella and trochlea are disengaged, and the primary stabilizing forces are from the medial ligaments.
It originates directly from the caudolateral surface of the tarsometatarsus with the belly extending almost to the base of trochlea IV.
Identification of the carpometacarpus as Ichthyornis is based on the shape of the trochlea of the proximal end.
The bony anatomy of the distal femur and trochlea play a significant role in the stability of the patella and act as a static restraint to medial and lateral translation.
Davidson and colleagues reported on 10 patients (out of a cohort of 67) who underwent second-look arthroscopy with biopsy of both graft and host cartilage, histological analysis, and MRI at a mean of 40 months following the index osteochondral allografting procedure on the femoral condyles or trochlea.
In separate podium presentations, surgeons described the five-year results of the first 100 patients treated with Carticel to repair damaged cartilage on the thigh-bone part of the knee; the potential of Carticel in treating injuries to the trochlea, a specific area of the femur beneath the knee cap; and the results of Carticel compared with so-called marrow stimulation techniques, an alternative treatment for some cartilage injuries.
Changes in the femoral design often necessitate increased bone resection from the posterior condyles or the trochlea, which become problematic in smaller femora.
3) Moreover, the lateral portion of the patella is usually fully in contact with the lateral wall of the trochlea while the medial aspect of the patella appears to have little if any contact with the medial wall.
