Runners Knee

Whether your knee is clicking, locking, or popping, these are all indications that something is not quite right. In some cases, popping may be an indication of a ligament injury such as an anterior cruciate ligament , posterior cruciate ligament , or medial collateral ligament tear.

  • Pain that persists while walking
  • The knee abruptly giving out, causing you to fall and feel unstable while walking
  • Swelling within 24 hours after the initial injury

What Is The Knee Joint And Why Is It Vulnerable

The knee is the largest joint in the human body, and by its structure and functionality, it is also extremely vulnerable and susceptible to injuries and other problems that can cause pain in them. The knee is the joint that connects the bones of the upper part of the leg to the bones of the lower part of the legs. In more technical words, the knees are made up of two types of joints, which are the tibiofemoral joint and the patellofemoral joint. The tibiofemoral joint connects the tibia with the femur, and the patellofemoral joint connects the patella with the femur. These joints are a type of modified hinge joint which implies that the joining surfaces are shaped with each other in such a way that there will be movement in only one plane.

The knee joint can permit flexion movement , extension, and internal and external rotation to some extent. The knees have a range of motions they carry the whole weight of the body, they are constantly under stress, there is a production of torque from the twisting motions of the two bones, etc. All these points act as predisposing factors which can cause sharp and sudden pain in the knees.

Is The Sound That My Knee Makes Bad

Gout Knee Pain

As we reviewed in a popular post about the sounds that our knees make, we discussed that the majority of these sounds are not mechanical or dangerous! That means that you are probably not bone on bone or grinding away the insides of your knee when you bend it. Yes, these sounds can be annoying or even embarrassing, but they are rarely dangerous. The most common cause of this grinding sensation or sound is actually due to inflammation of the tissues inside the knee. You do not need cortisone or lubricating injections to treat these sounds or sensations.

Tendinopathy And Muscle Complex Injuries

Tendon injuries are associated with repetitive mechanical stresses that cause degenerative lesions. Hamstrings, gastrocnemius, and popliteus tendon typically cause posterior knee pain.

The hamstrings are frequently injured in sports that require sprinting. Semimembranosus tendinopathy usually presents as an aching pain localized to the posteromedial knee with tenderness on palpation inferior to the joint. Some of the possible risk factors for hamstring injury include body mechanics, flexibility, balance, hamstring strength, improper warm-up, fatigue, specific activities, running techniques, and psychosocial factors.

The gastrocnemius muscles superficial location and action across the knee and ankle make it susceptible to injury. Pain in the gastrocnemius occurs during knee flexion with resistance and during calf raises.

The popliteus muscle can also be a significant source of posterior knee pain. Both the muscular and tendinous aspects of the popliteus can be injured. Injuries to the popliteus may promote injuries to other structures in the postero-lateral complex and to ligaments of the knee. The mechanism of injury is thought to occur from direct stretch or when overused to maintain posterolateral stability. Guha et al. suggested that a stable knee with posterolateral pain and hemarthrosis on exam indicates a rupture of the popliteus tendon.
