A locked knee in extension: a complication of a degenerate knee with patella alta.
نویسندگان
چکیده
We present a case of superior dislocation of the patella trapped by interlocked osteophytes. Unlike previous reports, in which the mechanism resulted from a blow to the inferior pole, it is postulated that increased load on the extensor mechanism, combined with patella alta and patellofemoral osteophytes, caused locking of the knee in extension.

Influence of patella alta on knee extensor mechanics.
The purpose of this study was to compare the knee extensor mechanics in persons with and without patella alta. Thirteen subjects with patella alta and 14 subjects with normal patellar position participated in the study. Sagittal and axial MR images of the knee were acquired at 0 degrees , 20 degrees , 40 degrees , and 60 degrees of knee flexion. Measurements of actual moment arm, patellar ligam...

Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...

Figure 1. Lateral knee radiograph showing patella alta. A 68-year-old male presented to the emergency department with anterior right knee pain after falling at home and directly hitting his patella on the stepladder edge while he was going upstairs. Physical examination revealed infrapatellar region painful swelling and impaired knee extension. Knee radiographs showed no fracture; however, the ...
متن کاملBilateral recurrent discloation of the patella associated with below knee amputation: A case report
BACKGROUND Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. CASE PRESENTATION A 25 year old male patient with bilateral below k...
متن کاملIs there a biomechanical explanation for anterior knee pain in patients with patella alta?: influence of patellar height on patellofemoral contact force, contact area and contact pressure.
The purpose of this study was to test the hypothesis that patella alta leads to a less favourable situation in terms of patellofemoral contact force, contact area and contact pressure than the normal patellar position, and thereby gives rise to anterior knee pain. A dynamic knee simulator system based on the Oxford rig and allowing six degrees of freedom was adapted in order to simulate and rec...
