Many adults struggle with routine aches and pains as they age. While osteoarthritis is the most common cause of knee pain, there are other forms of arthritis that also affect the knee, such as rheumatoid arthritis and psoriatic arthritis. Fortunately, several treatments are available to mitigate symptoms and help patients enjoy a higher quality of life without invasive joint surgery. With offices in Oregon, Washington, and Arizona, the team at Reflex Knee Specialists offers comprehensive knee evaluations to identify the underlying conditions that cause knee arthritis. Here, we briefly summarize the different types of arthritis that affect the knee joints. Rheumatoid ArthritisRheumatoid arthritis (RA) is an autoimmune disorder that primarily affects joints. While the cause is unknown, the risk of developing RA increases with age. Rates are higher among women than men. This form of arthritis most commonly affects the hands and wrists, but may also involve the knee.Patients with RA often have symptom flare-ups followed by periods of remission. Symptoms include:Joint stiffness and swellingPain that’s worse after intensive exercise or periods of restClicking, locking, or grinding sensation in the jointsJoint weakness and fatigueThere is no cure for RA, but there are effective treatments that can slow the progression of the disease. Patients with RA may take medications including corticosteroids, nonsteroidal anti-inflammatory drugs, and biologics that suppress the body’s immune response. OsteoarthritisOsteoarthritis (OA) is the most common form of arthritis and usually affects people with a prior knee injury (e.g. ACL or meniscal tear) and adults over age 45. Characterized by chronic inflammation, the OA process results in cartilage breakdown and dysfunctional biomechanics. Signs and symptoms of OA include joint stiffness and swelling, as well as pain that gets worse with exercise or activity.Although there is no cure for osteoarthritis, there are several treatments that can minimize the symptoms without surgery. These include:Platelet-rich plasma (PRP) treatment Viscosupplementation Ozone joint therapy Physical therapy Knee bracingSupplements, nutrition, and lifestyle changes can also help improve joint health. Psoriatic ArthritisThis form of arthritis develops alongside psoriasis, a chronic disorder that causes patches of red, scaly, irritated skin. While anyone can get psoriatic arthritis, it is most common among adults between ages 30 and 50. The National Psoriasis Foundation reports that psoriatic arthritis often develops about 10 years after the onset of psoriasis itself.Patients with psoriatic arthritis may experience symptoms that include:Joint pain and stiffnessRedness and swelling in the hands and feetPitted or crumbling nail bedsLower back painWhile there isn’t a cure for psoriatic arthritis, certain medications can help ease symptoms. These include:CorticosteroidsNonsteroidal anti-inflammatory medicines (NSAIDs)BiologicsPhysical therapy can also help ease pain and improve a patient’s range of motion. Crystal-induced ArthritisCalcium pyrophosphate dihydrate crystal deposition disease (CPPD) is a form of arthritis that mostly affects older adults. CPPD is caused by calcium crystals that develop in joint cartilage and synovial fluid. It’s not clear why these crystals form, but they can cause symptoms including joint pain, swelling, and stiffness. The joints may be red or warm to the touch.This type of crystal-induced arthritis is also known as pseudogout because the symptoms are similar to gout, another crystal-induced arthritis that is caused by urate crystals in the joint fluid. CPPD most often affects the knees and wrists; gout typically affects the big toe and/or knee joints. A sample of synovial fluid may be analyzed to confirm a diagnosis of CPPD.Treatments for crystal-induced arthritis include anti-inflammatory drugs and corticosteroids. Patients with gout and elevated serum levels of uric acid may be put on a medication to lower urate levels (Allopurinol). Joint injection treatments may offer pain relief and help reduce swelling.
