Understanding Knee Pain
What is knee pain?
Knee pain refers to any discomfort or soreness in or around the knee joint. This symptom can result from a variety of factors, including injuries, underlying medical conditions, or mechanical dysfunctions. When doctors refer to “knee pain,” they are indicating a symptom that can stem from multiple sources, impacting the joint’s overall function.
Common symptoms of knee pain
Typical signs of knee pain include stiffness, swelling, and a feeling of instability or weakness in the joint. Patients may find it challenging to bend or straighten their knee, and they might hear clicking or popping sounds during movement. Additionally, knee pain can stem from dysfunction in the lower leg or issues within the lumbo/pelvic/hip complex, affecting how forces are transmitted through the knee.
For patellar tendinopathy (jumper’s knee) or chronic patellofemoral pain, shockwave therapy can accelerate recovery by promoting tendon healing and reducing inflammation.
Causes of Knee Pain
Several factors can contribute to the development of knee pain:
Overuse injuries
Participating in sports or engaging in repetitive activities can lead to overuse injuries, causing inflammation of the knee structures, such as tendons and ligaments, resulting in pain and discomfort.
Arthritis and age-related changes
As individuals age, the cartilage in the knee joint may wear down, leading to conditions like osteoarthritis. This degenerative disease, as detailed by UK government health resources, can cause pain, swelling, and decreased mobility due to the breakdown of cushioning in the joint.
Trauma and accidents
Falls or injuries, such as ligament tears or fractures, can lead to acute knee pain. These injuries often require immediate medical attention to prevent long-term complications.
Postural and biomechanical issues
Poor posture or improper movement patterns can place excess stress on the knee joint, leading to pain during physical activities. Additionally, knee pain can result from lower leg dysfunction or issues within the lumbo/pelvic/hip complex, which can alter the mechanics of the knee. In many cases, patients may also benefit from hip and groin pain treatment to restore balance and improve biomechanics.
