Seventeen @entity1 with strictly unilateral medial knee @entity571 that justified surgical treatment constituted the study group. No @entity1 had any symptoms from the hip or @entity3681 or from the other knee. Eight @entity1 were operated with high tibial osteotomy and nine were operated with unicompartmental prosthetic replacement (Brigham model). The forces and the external moment about the hip, knee, and @entity3681 of the involved and uninvolved leg were calculated before and 1 year after corrective surgery and compared to the external moment in 10 normal controls. Clinical examinations was performed and the hip-knee-ankle angle in the involved leg was determined from whole-leg weightbearing radiographs before and 1 year after surgery. The external moments about the hip, knee, and @entity3681 and the knee moment arms at mid-stance in the frontal plane during gait were determined with a Kistler force plate and a videorecording system. All @entity1 improved clinically after surgery. The mean hip-knee-ankle angle changed from 11 degrees of varus to 0 degrees. In the uninvolved leg the mid-stance adduction moments about the hip and knee joints were significantly increased compared to normal subjects in the control group before surgery, but reduced to a normal level 1 year after surgery. This reduction was mainly due to a significant reduction of the medially directed force. The moments about the @entity3681 were not found to be changed by the @entity85 or by the corrective surgery. RELEVANCE: This study demonstrates that a @entity893 in the @entity3331 is accompanied by increased load about the uninvolved hip and knee joint. One might expect a more rapid progression of @entity179 as a consequence of such increased load. The reduced load after surgical correction of leg alignment might be beneficial to @entity1 with @entity571 of their hip and knee joints.

Surgical correction of leg alignment in unilateral knee XXXX reduces the load on the hip and knee joint bilaterally.
