Patella Infera:
-
Subluxation of the Patella:
- Discussion:
- patella alta refers to an abnormally high patella in relation to femur;
- may result in
Subluxation and dislocation of patella;
- Associated Conditions:
-
dislocation or subluxation of the patella;
- abnormal trochlea;
- hypoplasia of the vastus medialis
- Radiographs:
- position of patella can best be determined on the
Lateral Radiograph
w/ the knee flexed at 30 deg;
-
Insall's Ratio:
- length of patella ligament =
diagonal length of patella;
- variations of more than 20% are considered abnormal;
-
Blackburne Method:
- Treatment:
- lateral retinacular release is a poor choice in this condition
