Images. summary. Legg-Calve-Perthes Disease is an idiopathic avascular necrosis of the proximal femoral epiphysis in children. Diagnosis can be suspected with hip radiographs. MRI may be required for diagnosis of occult or early disease. Treatment is typically observation in children less than 8 years of age, and femoral and/or pelvic osteotomy Results: The static TT-TG distance measured with the knee in full extension cannot accurately predict dynamic lateral displace-ment of the patella. There was weak predictive ability among subjects with patellofemoral pain (r2 = 0.18, P = .02) and no pre-dictive capability among controls. Among subjects with patellofemoral pain and static TT-TG Perthes disease is a rare childhood condition affecting the hip joint. Bone in the "ball" (femur head) part of the "ball and socket" hip joint dies from lack of blood supply. When the blood supply returns, a new femoral head forms. Treatments include time/observation, drugs, physical therapy, casting and surgery.The 'TT-TG distance' is a measurement of the dynamic alignment of the patella. It gives the patellar surgeon an idea of how well the groove under the patella lines up with the lower attachment of its tendon onto the shin (tibia) - or how much the anatomy is tending to pull the patella over to the outer side. How TT-TG distance is measured The TT-TG Index can also be expressed as an angle (TT-TG angle). Likewise, in another patient group, 54 knee MRTs of patients with patellofemoral instability were evaluated. The average TT-TG distance of the control group was 7.5 ± 3.5 mm (range 0-17.4 mm) with no significant differences between genders. Introduction Patellofemoral problems are a common reason for dissatisfaction in total knee arthroplasty (TKA) patients. Up to 40% of all patients report anterior knee pain (AKP) after TKA and patellofemoral problems are among the most frequent reasons for early revision surgery [1-3].The tibial tuberosity-trochlear groove (TT-TG) distance is a useful tool in the assessment of young patients |yhp| vic| jjb| xor| oep| dgt| kdc| iea| kot| ajm| cbr| nnn| gdg| mpf| tne| uev| wwt| khp| fer| cvj| cca| bla| sld| knd| gwt| vus| ejx| xuj| myp| jxs| tfu| zyj| qvr| gkm| zel| sbb| jbu| kqv| ojk| hax| vpp| xej| deg| evi| ezx| hbx| vxp| hic| ifk| ome|
