Aim: To evaluate the functional outcome of surgical displacement of a congenital knee dislocation with or without arthrogryposis in the 6-month age group.

Methods: This Descriptive study conducted at Orthopedics Department in the Bolan Medical Complex Quetta. Group A includes patients with type III congenital dislocation of the knee (total dislocation), isolated dislocation of the knee joint for more than 6 months, dislocation of the hip and knee and clubfoot. People with paralysis disorders and unable to sit due to weakened muscle function were excluded from the study. Open reduction of the knee joint with a midline dorsal incision and plasty of the quadriceps V-Y quadriceps. Displaced knees were stabilized with the Plaster of Paris at 70 ° knee flexion for 5-6 weeks using the Ferris and Aichron defined knee function scoring system.

Results: In group B, 6 patients (12 knees) had recurrent stiffness with poor results, 5 patients (10 knees) had moderate and no good or excellent. Results in group A (knee dislocation with or without dislocation of the hip and clubfoot) were good or excellent in 22 patients (36 knees), moderate in 4 patients (7 knees) and severe with relapse of stiffness in 1 patient (7 knees).

Conclusions: The results of the surgery were excellent in isolated congenital knee dislocations and satisfactory in knee dislocations caused by clubfoot and hip dislocations. The outcome was less promising for arthrogryposis (amyoplasia) and older walking age groups.

Key words: arthrogryposis, congenital, dislocation, isolated, knee.
