A more laterally displaced patella was associated with increased lateral joint space narrowing; odds ratios were 1.00, 2.16, 4.22, and 8.26 (p for linear trend < 0.0001).
Pressure in the medial and lateral joint compartment was recorded using pressure-sensitive films.
Through these 2 portals, the dorsal capsule is released and the medial and lateral joint gutters can be cleared up.
There was a significant amount of improvement in patients with a minor loss of medial and lateral joint space in all outcome measures.
The adductor hallucis tendon is released, a lateral joint longitudinal capsulotomy is performed, and a second midline incision is made.
Furthermore, for both techniques, the amount of external rotation was significantly less when compared with the intact knee (the lateral joint was slightly overconstrained).
A second wire is placed in the lateral joint fragment using the same procedure, and now both the anterior and posterior fragments are held.
The osteotomy line is drawn on the proximal tibia, aiming for a point on the lateral metaphysis approximately 1 2 cm from the lateral joint line.
Synovium was harvested from the cranial, caudal, medial and lateral joint capsule, fixed in 10 % formalin, sectioned and stained with Hematoxylin and Eosin.
It is advised that a bone bridge of approximately 10 mm be maintained on the lateral side and that the lateral extent of the osteotomy be closer to the lateral cortex than to the lateral joint line.
If varus deformity is not present, they suggested that the patient should undergo soft tissue reconstruction; if this deformity is present, it is important to evaluate if a lateral joint line opening is associated.
