In medicine, Clarke's test (also known as the Osmond-Clarke test or patellar grind test) is a component of knee examination which may be used to test for patellofemoral pain syndrome, chondromalacia patellae, patellofemoral arthritis, or anterior knee pain. It is not a standard part of the knee examination but is used to diagnose anterior knee ...
Valgus stress test can be performed with the examined knee in 25 degrees flexion to determine the integrity of the medial collateral ligament. Similarly, varus stress test can be performed to access the integrity of the lateral collateral ligament. The degree of collateral ligament sprain can also be assessed during the valgus and varus tests.
The questions on the WOMAC are a subset of the questions of the Hip disability and osteoarthritis outcome score (HOOS). [4] Thus, a HOOS survey may also be used to determine a WOMAC score. A WOMAC test takes about 12 minutes, but is also available in a short form, (although this has not been as extensively tested as the full version).
A blood test could help predict knee osteoarthritis at least eight years before the signs of the disease show up on X-rays, a new study indicates. Blood test may be able to detect osteoarthritis 8 ...
Osteoarthritis is the most common form of arthritis, affecting about 237 million people or 3.3% of the world's population as of 2015. [4] [12] It becomes more common as people age. [1] Among those over 60 years old, about 10% of males and 18% of females are affected. [2] Osteoarthritis is the cause of about 2% of years lived with disability. [12]
The patellofemoral glide, tilt, and grind tests (Clarke's sign), when performed, can provide strong evidence for PFPS. [3] [19] Lastly, lateral instability can be assessed via the patellar apprehension test, which is deemed positive when there is pain or discomfort associated with lateral translation of the patella.
Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage.. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage.
This constitutes a positive Thomas test. [2] Sometimes, with a very flexible patient, the Thomas test will be normal despite a psoas dysfunction being present. However, in the patient with a normal hip joint, a positive test is a good indicator of psoas hypertonicity. [2] Other signs from the Thomas test:
