Knee Arthritis
Arthritis of the Knee | Joints. Pain, swelling, and stiffness
Arthritis, characterized by inflammation in one or more joints, manifests with primary symptoms of pain, swelling, and stiffness. This condition can impact any joint in the body but is notably prevalent in the knee.
Living with knee arthritis can pose challenges in performing daily activities like walking or climbing stairs, becoming a significant cause of work-related disruptions and a substantial disability for many individuals.
The two most common forms of arthritis are osteoarthritis and rheumatoid arthritis, with over 100 different variations identified. While arthritis is typically associated with adults, certain forms can affect children.
While a definitive cure for arthritis remains elusive, numerous treatment options exist to help manage pain effectively and enable individuals to maintain an active lifestyle.
Knee Anatomy Overview:
Your knee, the largest and most robust joint in your body, comprises three main components: the lower end of the femur (thighbone), the upper end of the tibia (shinbone), and the patella (kneecap). The crucial junctions where these bones meet are covered with articular cartilage—a sleek, lubricating substance that safeguards and cushions the bones during knee movements.
Adding to the knee’s structural integrity, two wedge-shaped pieces of cartilage known as meniscus act as efficient “shock absorbers” between the thighbone and shinbone. These resilient and flexible components play a vital role in cushioning the joint and maintaining its stability.
Surrounding the knee joint is the synovial membrane, a thin lining responsible for releasing a lubricating fluid. This fluid serves to enhance cartilage function by minimizing friction, contributing to the smooth and pain-free operation of the knee.

Arthritis Types and Their Impact on the Knee:
Several primary types of arthritis, namely osteoarthritis, rheumatoid arthritis, and posttraumatic arthritis, can significantly affect the knee.
1.Osteoarthritis:
The most prevalent form of arthritis in the knee is osteoarthritis, a degenerative condition categorized by wear-and-tear. Typically affecting individuals aged 50 and above, it can also manifest in younger people.
Osteoarthritis initiates the gradual breakdown of cartilage in the knee joint. Over time, the diminishing cartilage becomes frayed and rough, reducing the protective space between bones. This progression can lead to bone-on-bone contact, resulting in the formation of painful bone spurs.
Rheumatoid Arthritis and Posttraumatic Arthritis:
Rheumatoid Arthritis:
Rheumatoid arthritis, a chronic condition affecting multiple joints, including the knees, is characterized by its symmetrical impact on corresponding joints on both sides of the body.This autoimmune disease triggers inflammation in the synovial membrane covering the knee joint, resulting in pain and stiffness. The immune system, in this case, attacks its own tissues, causing damage to normal structures like cartilage and ligaments while softening the bone.
- Posttraumatic Arthritis:
Developing after a knee injury, posttraumatic arthritis can arise from various traumas, such as a broken bone affecting the joint surface or injuries like meniscal tears and ligament damage. These injuries may lead to joint instability and increased wear over time, eventually culminating in arthritis.

Symptoms
A knee joint affected by arthritis may be painful and inflamed. Generally, the pain develops gradually over time, although sudden onset is also possible. There are other symptoms, as well:
- The joint may become stiff and swollen, making it difficult to bend and straighten the knee.
- Pain and swelling may be worse in the morning, or after sitting or resting.
- Vigorous activity may cause pain to flare up.
- Loose fragments of cartilage and other tissue can interfere with the smooth motion of joints. The knee may lock or stick during movement. It may creak, click, snap, or make a grinding noise (crepitus).
- Pain may cause a feeling of weakness or buckling in the knee.
- Many people with arthritis note increased joint pain with changes in the weather.
Surgical Treatment:
If arthritis-related pain significantly impairs your daily life and nonsurgical methods prove ineffective, your doctor may recommend surgical intervention. It’s crucial to be aware that, like any surgery, knee procedures entail risks and potential complications. Your doctor will thoroughly discuss these aspects with you prior to the operation.
Arthroscopy: Arthroscopy involves the use of small incisions and thin instruments for both diagnosis and treatment of joint issues. While not commonly used for knee arthritis, arthroscopic surgery may be suggested when osteoarthritis coincides with a degenerative meniscal tear.
Cartilage Grafting (Cartilage Restoration): For younger patients with limited cartilage damage, normal cartilage tissue can be sourced from another part of the knee or a tissue bank to fill gaps in the articular cartilage.
Synovectomy: In cases of rheumatoid arthritis, a synovectomy may be performed to remove the damaged joint lining, alleviating pain and reducing swelling.
Osteotomy: Knee osteotomy involves cutting and reshaping either the tibia (shinbone) or femur (thighbone) to alleviate pressure on the knee joint. This procedure is suitable for early-stage osteoarthritis affecting one side of the knee, providing pain relief and enhancing joint function.
Total Knee Replacement or Partial (Unicompartmental) Knee Replacement (Arthroplasty): In this comprehensive approach, damaged cartilage and bone are removed, and new metal or plastic joint surfaces are positioned to restore knee function.

Recovery
Post-Surgery Recovery and Rehabilitation:
Following knee arthritis surgery, a crucial phase of recovery ensues, and its duration and rehabilitation specifics hinge on the surgical procedure undertaken.
Your healthcare provider might suggest engaging in physical therapy, a key component for recovering knee strength and reinstating a full range of motion. Depending on the nature of your surgery, temporary use of a knee brace, crutches, or a cane may be recommended.
