Patella alta and chondromalacia.
The Insall-Salvati method of determining the position of the patella by radiography was employed in fifty-one patients with chondromalacia patellae that had been proved at arthrotomy. There was no definite relationship between chondromalacia patellae and patella alta. There was, however, a highly significant statistical difference between the ratio of the length of the patella to that of the pa...
متن کاملTrochlear contact pressures after anteromedialization of the tibial tubercle.
BACKGROUND Anteromedialization is recommended for cartilage restoration of patellofemoral defects, with the presumption that it decreases contact pressures across the trochlea. No study has evaluated pressures on the trochlear side of the patellofemoral joint after anteromedialization of the tibial tubercle. HYPOTHESIS Anteromedialization of the tibial tubercle decreases contact pressure acro...
متن کاملPatellar instability.
Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus. Nonoperative treatment includes physical therapy, focusing on strength...
متن کاملMedial Patellofemoral Ligament Reconstruction Reduces Radiographic Measures of Patella Alta in Adults
Background Patellar height has long been considered a risk factor for patellofemoral instability. However, recent pediatric literature demonstrated a reduction in patellar height measurements following medial patellofemoral ligament (MPFL) reconstruction. Purpose To assess the mean change in patellar height and the percentage of skeletally mature patients with patellar height ratios reduced t...
