The knee loses its ability to transmit and distribute load and absorb mechanical shock. Persistent and significant swelling and stiffness in the knee. The knee may be not be fully mobile; there may be the sensation of knee locking or buckling in the knee. The full knee may be in full motion after tear of meniscus.
The bones of the knee are the femur, patella, tibia, and fibula. The fibula is on the lateral side of the knee and the patella has little effect on the medial side of the knee. The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau.
The medial collateral ligament (MCL), also called the superficial medial collateral ligament (sMCL) or tibial collateral ligament (TCL), [1] is one of the major ligaments of the knee. It is on the medial (inner) side of the knee joint and occurs in humans and other primates. Its primary function is to resist valgus (inward bending) forces on ...
Knee pain is more common among people working in the cold than in those in normal temperature. [21] Cold-induced knee pain may also be due to tenosynovitis of the tendons around the knee, in which cold exposure has a specific role, either as a causative or a contributing factor. [21]
Patellar tendinitis is an overuse injury from repetitive overloading or repetitive stress of the patellar tendon of the knee leading to microtears and inflammation that do not have time to heal before the next use. Patellar tendonitis is common in athletes who participate in activities that include a lot of jumping, changing directions, or running.
Treatment of the unhappy triad usually requires surgery. An ACL surgery is common and the meniscus can be treated during the surgery as well. The MCL is rehabilitated through time and immobilization. Physical therapy after the surgery and the use of a knee brace help speed up the healing process. A typical surgery for a blown knee includes:
The popliteus tendon's main attachment is on the femur at the proximal portion of the popliteus sulcus. As the tendon runs posteriorly and distally behind the knee, it gives off 3 fascicles that attach to and stabilize the lateral meniscus. The popliteus tendon provides static and dynamic stabilization to the knee during posterolateral rotation.
These two ligaments function to limit sideways movement of the knee. [2] The cruciate ligaments form an "X" inside the knee joint with the anterior cruciate ligament running from the front of the tibia to the back of the femur, and the posterior cruciate ligament running from the back of the
