What is valgus of the knee?
Valgus knee deformity is defined as a tibio-femoral angle of greater than 10°. Typically, the deformity is the result of changes to both the bony and soft-tissue components around the knee.
How do you measure knee valgus?
Draw a line connecting the center of the knee to the center of the ankle. 5. Measure the angle between the 2 lines. A measurement of 0°/180° implies no deformity; otherwise, the observed angle is the angle of varus or valgus present (valgus if foot is lateral, varus if foot is medial).
What causes valgus alignment?
It happens when your tibia, the larger bone in your shin, turns inward instead of aligning with your femur, the large bone in your thigh. This causes your knees to turn outward. The opposite of varus knee is valgus knee, which makes some people knock-kneed.
Why do knees get valgus?
Knee valgus results from a combination of femoral and tibial motions, which can be influenced by the joints proximal and distal to the knee, including the trunk, hip, and ankle. Lack of femoral control can result in excessive adduction and internal rotation, which can stress the ACL.
What is normal knee valgus angle?
The knee valgus angle was defined as the angle enclosed by the distal femoral anatomical axis (line AB) and the femoral mechanical axis (line AC). The average (mean±SD) of knee valgus angle for the 128 femurs was 6.20°±1.20° (range, 3.05° to 10.64°).
How do I strengthen my valgus knee?
Resistance band squats and hip bridges, and Side Lying Clams are good strengthening and activation exercises to prevent valgus knee collapse, as they operate in a deeper flexed position – where the collapse tends to happen, so are more specific.
What causes excessive knee valgus?
Because excessive knee valgus (MKD and 3D) is most likely caused by a combination of hip- and ankle-muscle imbalances, comprehensive strategies that focus on the joints proximal and distal to the knee should be investigated to determine if knee alignment can be corrected during functional tasks.
What is total knee arthroplasty (TKA)?

What is the evolution of total knee replacement (TKR)?
Evolution of TKR (cont) Frank Gunston (1971), developed a metal on plastic knee replacement. John Insall (1973), designed what has become the prototype for current total knee replacements.
When should TKR be done?
TKR should be done before things get out of hand and the patient experiences a severe decrease in ROM, deformity, contracture, joint instability or muscle atrophy 32. Evaluation Of Patient Before Surgery • A Complete Medical History • Thorough Physical Examination • Laboratory Work-up • Anesthesia Assessment 34
What are the causes of TKR?
It occurs in abduction adduction, internal and external rotation and obviously the flexion and extension The most common conditions that can lead to TKR are osteoarthritis which may be primary and secodary and the rheumatoid arthritis. Arthritic conditions can be classified as non inflammatory and inflammatory types.
