Knee Osteoarthritis

Osteoarthritis of the knee is a common condition that mostly affects adults over age 50, although it can strike at any age. The condition is marked by the wearing away of cartilage, the protective cushion that prevents your bones from making contact with one another as you move. In the later stages of knee OA, reduced lubrication from synovial fluid contributes to further degeneration of the joint.

Because osteoarthritis tends to affect older people, it was once assumed to be an inevitable consequence of aging, brought on by wear and tear over time. However, recent clinical evidence shows that osteoarthritis is both preventable and reversible. Moreover, new research indicates that the pain associated with osteoarthritis is not directly caused by lost cartilage, but by sympathetic nerves that sprout in damaged synovial tissue and the skin covering the arthritic joint.

Knee Osteoarthritis Symptoms

Osteoarthritis is a progressive disease that worsens gradually over time. In the early stages, you may experience no symptoms at all. As the disease progresses, symptoms become more noticeable, and may become debilitating in the later stages.

Symptoms of knee OA include:

  • Pain during physical activity
  • Pain that is more intense first thing in the morning, or following prolonged inactivity
  • Inflammation and redness, with the joint feeling warm to the touch
  • Tenderness
  • Knee locking or buckling
  • Popping or crackling in the joint
  • Stiffness and reduced range of motion
  • Reduced joint space when viewed on imaging results

Knee Osteoarthritis Diagnosis

Initial diagnosis of knee OA is based on symptoms and medical history, followed by a physical exam. Your doctor may also order diagnostic tests, such as x-rays or blood tests.

At NYDNR, we use high-resolution diagnostic ultrasonography to view the knee joint in motion, in real time. Coupled with patient feedback during the procedure, real-time ultrasound gives us a vivid image of the nature and severity of your knee OA.

Knee Osteoarthritis Treatment

There are a number of treatments available to address knee OA, each with its benefits and limitations. However, it is universally agreed that regular exercise is key to preventing, stopping and reversing knee OA.

Popular treatment options include:

  • Physical therapy exercises and stretches to strengthen and balance the structures supporting the knee
  • Weight loss to reduce joint loading
  • NSAIDs and topical analgesics to reduce pain and inflammation
  • Wraps and braces to provide additional joint support

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
