The condition causes degenerative changes in the joint. Because of its widespread nature, tricompartmental osteoarthritis may be more severe than other forms of osteoarthritis.
In this article, we take an in-depth look at tricompartmental osteoarthritis, including the symptoms, causes, diagnosis, and treatment for this painful condition.
What is tricompartmental osteoarthritis?
Osteoarthritis, or osteoarthrosis, is the most common condition that affects the joints. According to the Arthritis Foundation, osteoarthritis affects approximately 27 million people in the United States alone.
The condition most commonly affects the knees and is also referred to as wear-and-tear arthritis, as it occurs due to the cartilage in the joints breaking down over time.
This wear-and-tear process is referred to as degenerative changes, and it leads to symptoms that include stiffness, pain, and joint effusion or an increased amount of fluid in the joint.
Four bones meet at the knee. The tibia and fibula connect from below the joint. The femur connects from above, and the patella or kneecap sits just atop the femur and the connecting cartilage.
The meeting of these bones creates the three compartments in the knee:
- patellofemoral compartment, where the kneecap and femur meet
- medial femorotibial compartment, or the inside of the knee
- lateral femorotibial compartment, or the outside of the knee
Osteoarthritis can occur in any of these compartments, but tricompartmental osteoarthritis happens when all three compartments of the knee are affected.
Tricompartmental osteoarthritis is often considered to be worse than other forms of osteoarthritis, as the entire area of the knee is affected and loss of cartilage or the synovium or joint lining may be more widespread.
To correctly diagnose tricompartmental osteoarthritis, a doctor may first ask questions and perform a physical exam.
Osteoarthritis involves knee pain and several other symptoms, so doctors may ask if the person has symptoms such as:
- cracking or popping in the knee
- grating feeling whenever the knee is moved
- stiffness in the knees in the morning or after periods of sitting or resting
- tenderness and swelling in the area
- feeling as if the joints are colder than normal
Doctors will often use imaging tests, such as X-rays, to confirm the diagnosis. They will look for any signs of cartilage that has worn away or extra bony growths where the cartilage should be. Osteoarthritis may be more challenging to diagnose in its early stages but easier in later stages.
If there is still any doubt, doctors may recommend a soft tissue scan, using an MRI scanner, to thoroughly check the ligaments, cartilage, and synovium.
There is currently no cure for osteoarthritis because cartilage cannot be replaced once it has eroded.
The optimal treatment for tricompartmental osteoarthritis varies based on the severity of the condition. Treatment usually involves managing symptoms, preventing progression of the disorder, or surgery.
The following treatments can help with the symptoms of osteoarthritis:
- Ice and heat. Pain and swelling in the knee may respond well to ice and heat packs at different times of the day. Elevation may also reduce swelling around the knee.
- Pain relievers. Over-the-counter (OTC) anti-inflammatories and painkillers can reduce pain and swelling in many cases. Prescription medications and COX-2 inhibitors may help if OTC versions are not effective.
- Corticosteroid injections. A doctor can inject corticosteroids directly into the knee to relieve pain and inflammation if other medications have not worked.
- Lifestyle changes. A person can reduce stress on their knee by avoiding high-impact exercises, and replacing these with low-impact ones, for example, swimming or cycling. Low impact exercise may strengthen the areas around the joint to reduce impact on the joint itself.
- Medical devices. Using medical devices can help to reduce pressure in the joints. These can include canes for walking, wearing shock-absorbing shoes or wedge insoles, or using a sleeve or brace to stabilize the knee.
- Injection to the knee. A doctor can administer an injection, a form of hyalagan, into the knee to improve symptoms.
- Surgery. In well-advanced cases or ones that do not respond to other treatments, surgery may be recommended. It is usually reserved for people who cannot function due to osteoarthritis, as surgery on the knee can be complicated.
If a doctor recommends surgery for tricompartmental osteoarthritis, this often involves a total knee replacement or total knee arthroplasty. In this surgery, doctors replace the damaged bone and joint with a plastic and metal joint.
It can take several months to recover from total knee arthroplasty. Regular physical therapy sessions will help strengthen the legs and allow a person to walk normally again.
Osteoarthritis is a common chronic degenerative condition, currently without a complete cure. Tricompartmental osteoarthritis symptoms affect the entire knee and may be more widespread.
Managing these symptoms may help in many cases, and maintaining a healthy lifestyle may also slow the progression of the disorder. Surgery can help restore function in the affected knee if other interventions do not work.
