This case serves to add to the literature of the rare instances where open reduction of an acute patella dislocation is required, in this instance, for what was likely an incarcerated fracture and a chondral
Radiographs cannot detect early chondral
"In our study, the largest of skeletally immature patients to evaluate independent risk factors, a delay in treatment of more than 12 weeks had about a four-fold increase in irreparable medial meniscus tears, an 11-fold increase in lateral compartment chondral
injuries and a three-fold increase in patellotrochlear injuries," said Ganley.
Shelbourne's experience involving nearly 2,800 ACL reconstructions in a recent 12-year period, he identified chondral
defects in 23% of patients with an acute ACL tear and 54% of those undergoing surgery for chronic ACL laxity.
For instance, the dECM hydrogels, gelling at 37[degrees]C, could be easily used in microfluidic models to better mimic the chondral
environment and to provide the cells with an instructive cell niche, representing a significant step forward in the development of biomimetic chondral
Upon further examination, we discovered an ACL tear, an intra-articular loose body, and a grade IV chondral
lesion on the medial femoral condyle measuring approximately 20 mm x 20 mm (Figure 4).
This publication, with the title 'A customised femoral resurfacing metal implant for focal chondral
lesions - radiostereometric analysis and subjective outcome of the first ten patients' by StAaAaAeANlman, A., SkAaAaAeA ldenb O., Martinez-Carranza, N., HAaAaAeA gstrAaAaAeA m, M.
The articular surfaces were well preserved without any evidence of chondral
collapse or osteoarthritis.
These lesions are described as chondral
(limited to the cartilage surface) or osteo- chondral
(extending beyond the calcified cartilage layer into the subchondral bone).
Partial meniscectomy or trimming of unstable segments for meniscal tears and shaving, abrading and microfracture were done for patients with chondral
lesions according to its grading.
Sensitivity for diagnosing chondral
lesions of the knee has been reported as being considerably lower (45%-69%).
Fourteen patients were excluded: 6 because they did not actually have a medial meniscal tear, one because he also had a lateral meniscus tear, 3 due to a major chondral
flap, 2 who had already undergone meniscal repair, and 2 due to an osteochondral microfracture.
