Patella Baja or Patella Inferna is a low lying Patella (Kneecap) with respect to the Femoral Trochlea or groove. It may be either congenital (from birth) or acquired (after Total Knee Replacement Surgery)
Congenital: From birth
Acquired: After Total Knee Replacement
Patella Baja is also called Patella Infera.
Patella Baja may lead to considerable pain, as the Patella impinges against the Tibia when the Knee bends and arthritic changes can occur at the back of the Patella.
