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°.

16 Αυγ 2023 · Knee flexion is the degree to which you can bend your knee. Knowing your knee flexion limit can help you to assess your range of motion, which may be helpful if you're recovering from an injury or surgery.
3 Νοε 2023 · There are four main movements that the knee joint permits: Extension – produced by the quadriceps femoris, which inserts into the tibial tuberosity. Flexion – produced by the hamstrings, gracilis, sartorius and popliteus. Lateral rotation – produced by the biceps femoris.
2 ημέρες πριν · As the knee is a synovial hinge joint, its function is to permit the flexion and extension of the lower leg relative to the thigh. The range of motion of the knee is limited by the anatomy of the bones and ligaments, but allows around 120 degrees of flexion.
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]
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.
Horizontal (latitude) lines on the femoral articular surfaces represent various anatomical areas of the femoral articular cartilage, at full extension of the knee, 45, 90 and 120° of flexion of the knee, with reference to the anterior tibial articular margin.
