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.

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]
A flexion deformity of the knee is the inability to fully straighten or extend the knee, also known as flexion contracture. Normal active range of motion (AROM) of the knee is 0° extension and 140° flexion.
10 Ιουν 2021 · during normal motion, the contact point between the femur and the medial tibial plateau is relatively stationary (the medial pivot point of the knee). the contact point between the femur and the lateral tibial plateau moves progressively posterior as the knee flexes.
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.
It is made up of extension (the ability to straighten your leg) and flexion, the ability to bend your leg. When we put the two together we get your range of motion. Ideally, this should be from 0º extension (completely straight leg) to 130º, a fully flexed leg. Some prostheses stop a little short of 130, and that is okay.
Free. Metrics. Dr. Mark Pagnano, the Guest Editor of the Proceedings of The Knee Society, has suggested we republish Jacob Kulowski's account of correcting knee flexion contractures using a turnbuckle cast. This account is an excellent example of the best clinical research reporting of the time (1932).
