The sulcus angle and malalignment of the extensor mechanism of the knee.
Anterior knee pain due to dysplasia of the extensor mechanism is common. We have studied 137 knees (103 patients) in order to identify a rapid and reproducible radiological feature which would indicate the need for further analysis. Overall, 67 knees (49%) had at least one radiological abnormality; 70 (51%) were considered normal. There were five cases of Dejour type-3 dysplasia of the femoral ...
متن کاملImaging of postoperative knee extensor mechanism.
Disorders of the anterior knee are common and include patellofemoral syndrome, patella instability, patella fracture, and patellar and quadriceps tendon ruptures. Depending on the operative procedure performed, the post-operative imaging appearance of these knees may be confusing. It is crucial for the radiologist to be familiar with the procedures performed in order to recognize the postoperat...
متن کاملExtensor mechanism allograft in total knee arthroplasty
OBJECTIVE To analyze the experience with allograft transplantation of the extensor mechanism in total knee arthroplasty and compare results with the international experience. METHODS We retrospectively evaluated three cases of extensor mechanism allograft after total knee arthroplasty performed in our hospital with the aid of one of the few tissue banks in Brazil and attempt to establish whet...
متن کاملThe Moment Arm of the Knee Extensor Mechanism
The moment arm (MA) of the knee extensor mechanism has been reported by a number of researchers, although it has been defined and measured differently in these studies. The aims of this study were: (1) to quantify the MA of the knee-extensor mechanism, which is represented by the MA of the patellar tendon at the knee; and (2) to show that the MA of the patellar tendon is related to the size of ...
متن کاملReconstruction of the extensor mechanism after major knee resection.
In periarticular knee resections, the relative lack of soft tissue coverage and need to reattach the extensor mechanism after en bloc resection of the tibial tuberosity with the tumor specimen complicate reconstructions and decrease postoperative function and stability of the knee joint. Distal femoral reconstructions are less problematic; muscular attachments are relatively few, neurovascular ...
