The signs of knee arthritis include swelling, stiffness and pain when walking and sitting, according to the American Academy of Orthopaedic Surgeons. Patients with knee arthritis typically experience an increase in pain throughout the day, and in some cases, when changes in the weather occurs, reports Heathline.
Three types of knee arthritis include osteoarthritis, post-traumatic arthritis and rheumatoid arthritis, explains Healthline. Patients with osteoarthritis typically experience pain that continues to worsen over time, while patients with post-traumatic arthritis, which is caused by an injury, may not experience pain until years after the injury heals, states the AAOS. Patients with rheumatoid arthritis experience fatigue, along with a warming sensation around the knee, claims WebMD.
Additional signs of these types of knee arthritis include knee buckling, grinding sounds, limited range of movement and deformities of the knee, according to Heathline.
To diagnose knee arthritis, patients typically undergo tests such as x-rays, MRI, CT scan or blood tests, reports the AAOS. Non-surgical treatment options for osteoarthritis and post-traumatic arthritis include physical therapy, over-the-counter pain medications and cortisone injections. Surgical treatment options include cartilage grafting, arthroscopy or a total or partial knee replacement, states the AAOS.
Non-surgical treatment options for patients with rheumatoid arthritis include prescription medications such as disease-modifying anti-rheumatic and nonsteroidal anti-inflammatory drugs, according to WebMD. Surgical treatment options include synovectomy or a total or partial knee replacement.
