Normal knee range of motion, aka knee ROM, is typically 0-135 degrees. Learn about knee ROM needed for daily activities, what limits knee ROM and how to improve it.
Range of Motion Normal Values. Each joint has a normal ROM range of values, while each person has a different amount of ability to achieve it. Below are generally accepted values for a normal ROM for some individual joints as measured in degrees: Table 1. Typical Joint Ranges [1]
30 Οκτ 2023 · The degree of possible knee flexion depends on the position of the hip joint and whether the movement is active or passive. When the hip is flexed, a maximum degree of flexion of 140° is achievable in the knee joint, whereas an extended hip allows for only 120°.
13 Ιουν 2016 · Flexion of the knee is now assessed. If the knee cannot be flexed more than 30 degrees to 40 degrees, we perform a quadriceps release rather than a V-Y turndown or tibial tubercle osteotomy. A V-Y turndown devascularizes the extensor mechanism, and adjusting the final length of the quadriceps mechanism is difficult.
At 60-90 degrees of knee flexion, the patella has maximum contact with the intercondylar groove (1/3 of the posterior surface area of the patella). At 135 degrees of knee flexion, the patella contacts the femur with its superior pole and rests below the intercondylar groove.
5 Δεκ 2016 · The tibiofemoral (knee) joint allows 2 degrees of freedom, flexion and extension, and internal and external rotation. Flexion and extension occur in the sagittal plane about a medial-lateral axis of rotation.
The main movement of the knee is flexion - extension. For that matter, the knee acts as a hinge joint, whereby the articular surfaces of the femur roll and glide over the tibial surface. During flexion and extension, tibia and patella act as one structure in relation to the femur . [5]
