The Knee Glide features a convenient carrying handle and weighs just three pounds, making it easy to transport. It can be attached to the wall for added stability during use. Ligaments are bands of strong tissue that connect bone to bone. The knee has 4 major ligaments that connect the femur to the tibia:

There are two menisci in the space between the femoral and tibial condyles. They are crescent-shaped lamellae, each with anterior and posterior horn, and are triangular in cross-section. The surface of each meniscus is concave superiorly, providing a congruous surface to the femoral condyles and is flat inferiorly to accompany the relatively flat tibial plateau. [5] The horns of the medial meniscus are further apart and meniscus appears ‘C’ shaped, than those of the lateral one where meniscus appears more ‘O’ shaped. This is due to the increased size of the medial meniscus, which unfortunately leaves a large exposed area that in turn can be prone to injury. Medial rotation, as discussed earlier, occurs when the knee is in the last stage of extension, with some also occurring when the knee is flexed. It is primarily produced by the actions of popliteus, semimembranosus and semitendinosus, which are assisted by sartorius and gracilis. Lateral rotation is produced by biceps femoris and also occurs when the knee is flexed. A continuous passive motion (CPM) machine is initiated immediately following surgery. (e.g.: passive stretch, heel slide, and flexion exercise to evaluate own range of motion )

Thank you for sending me a complimentary Ortho-Glide for use following my total knee replacement. You will be pleased to know that I have found it excellent for carrying out my knee flexion exercises and can fully recommend it. Camanho G, Viegas A, Bitar A, Demange M, Hernandez A.

Innervation

The Knee Glide has a convenient carrying handle and weighs just 3 pounds, for easy transport. It can also be attached to the wall for added stability during use. Already after the first week of bed rest, patients are allowed to resume normal daily activities. Full weight bearing with the immobilizer is encouraged and crutches are only used for support or balance until the patient is comfortable walking without them. When the patient can demonstrate good leg control via good quadriceps activation and straight leg raises, the leg immobilizer is discontinued. In some cases, damage to the common peroneal nerve can lead to foot drop. [9] [42] Transverse ligament: connects the menisci anteriorly extending from the anterior margin of the lateral meniscus to the anterior horn of the medial meniscus. Its exact role is uncertain but it is thought that this ligaments stabilizes the menisci during knee movements and decrease tension generated in the longitudinal circumferential fibres. The patient with patellar instability will usually describe symptoms such as though the knee is slipping, giving way or giving out. Instability does not have to be the result of a macrotraumatic patellar dislocation or injury and is oftentimes subtle and microtraumatic in nature.

There are two ways to develop patellofemoral instability by dislocation of the patella. It can develop after a traumatic dislocation of the kneecap in which the medial kneecap-stabilisers are stretched or ruptured, which eventually can result in recurrent dislocations of the patella. The other way is caused by anatomical anomaly of the knee joint. Shelbourne, K. D., & Carr, D. R. Combined anterior and posterior cruciate and medial collateral ligament injury: nonsurgical and delayed surgical treatment. Instructional course lectures. 2003; 52: 413-418.During movement of the knee from flexion to extension, the femoral condyles roll and glide posteriorly over the tibial plateaus owing to their greater articular surface area. The posterior gliding motion is important because without it, the femur would simply roll off the tibia before full extension is complete. Additionally, as the articular surface of the lateral femoral condyle is less than its medial counterpart, the posterior gliding of the medial condyle during the last degrees of extension results in medial rotation of the femur on the tibia. Athletes must be guided in the process to return to the level prior to injury or even higher. To succeed specific exercises have to be integrated into the rehabilitation program. Not only the quadriceps muscle but also the pelvic stabilizers and the lateral trunk muscles have to regain force and dynamic stability.
