– See: – Bursae of the knee: – Pigmented Villonodular synovitis – Discussion: – synovial cavity is deepest layer of joint capsule & it often has several embryological invaginations called plica that persist into adult life; – these may cuase anterior knee symptoms, – although synovium membrane is attached all around, above to articular margins … Read more
Discussion a monarticular synovial proliferative disease which is characterized by the metaplastic conversion of cartilagenous tissue to ossified loose bodies; cartilagenous or osteocartilaginous metaplasia takes place w/in the synovial membrane of joints, bursae, or tendon sheaths; seen most often in middle-aged men; pts report pain and limitation of motion; location over one-half of cases occur … Read more
– Discussion: – synovial plica are folds of embryonic remnants of synovial membrane which, in fetus, divide knee is divided into medial, lateral, & patellar compartments; – although these membranes normally degenerate by the second trimester, (allowing knee to become one cavity), incomplete membrane degeneration will lead to the formation of plica – Medial (Shelf) Plica … Read more

Discussion is preferred by many for use in older children and adolescents; skeletal traction is applied w/ Steinman pin inserted thru distal femur; see: insertion technique knee should be flexed 30 deg to relax the hamstrings; deformity: w/ mid shaft frx, there is tendency is toward posterior angulation; to restore the normal anterior bowing of … Read more
