Varus and Valgus Knees in Children Kamal Ibrahim, M.D., FRCS(C), MA centered at the knee, Often accompanied by internal tibial torsion, which may accentuate Lateral thrust of the knee on walking due to varus instability X-ray: Standing AP of lower extremities from hip to ankle (knees forward): Orthopedics; OBJECTIVE: To investigate the impact of knee varus and valgus in varying degrees on the alignment in lower extremities of patients who received the total knee arthroplasty (TKA). PATIENTS AND METHODS: We retrospectively analyzed the condition of varus and valgus deformity in full-length X-ray films of double lower extremities in weight-bearing position of 120 patients before and Impact of Valgus vs Varus Mechanical Axis Seventy-one patients underwent full-length standing x-rays and knee-specific BMD measurements using dual-energy-x-ray important targets for further biomechanical studies to determine potential differences in dynamic loading of the knee between valgus and varus patients and The association of knee OA onset and malalignment is weaker (varus OR 2.1, P < 0.05; valgus OR 2.5, P < 0.05) [16, 17]. It is important that LE alignment is measured accurately, so that interventions can be prescribed appropriately, and research studies which include LE alignment can be compared to one another. deformity at the knee in approximate proportion to the percentage of the way that deformity is located toward the knee. Example 1 (Figure 4.1-A): A 10° varus deformity 80% of the way from the hip to the knee, or 20% of the way above the knee, would impart an approximately 8° varus deformity at the knee, which would be 100% on the femoral side. It is determined by the distal part being more medial or lateral than it should be. Whenever the distal part is more lateral, it is called valgus. Whenever the distal part is more medial, it is called varus. Therefore, when the apex of a joint points medially, the deformity, if any, would be called valgus, as the distal part points laterally. Learn about the characteristics of valgus and varus knee alignments, which are commonly called being knock-kneed and bow-legged, respectively. the x-ray beam centered at the knee. Knee alignment in the frontal plane (varus/valgus position) was measured as the angle (in degrees) formed from the intersecting femoral and tibial mechanical axes (Figure 1). The femoral axis was defined as a line drawn from the center of the femoral head to the center of the femoral intercondylar notch. The Women are more likely than men to have lateral OA. OA can routinely be diagnosed and confirmed by a series of X-rays of your knee. A weight-bearing X-ray will typically show that the joint space on one side of the knee has narrowed or is fully collapsed. Wearing an OA knee brace can help maintain normal leg alignment and reduce joint compression. Of the 261 knees in the analysis sample, 99 knees were varus (38%), 81 knees were valgus (31%), and 81 knees were neutral (31%) (Table 1). The distribution of varus ranged from 2° to 19° varus with 27% of varus knees greater than 5° varus.
