Understanding the Knee Joint

The knee joint is one of the body’s largest and most complex joints. It connects the thigh bone (femur) to the shin bone (tibia) and includes the kneecap (patella). 

The joint is supported by ligaments, tendons, and muscles, while articular cartilage covers the ends of the bones, allowing smooth movement. When this cartilage wears down, the knee becomes stiff and painful, leading to conditions like osteoarthritis of the knee.

What is Arthritis in the Knee?

Knee arthritis is a condition that causes inflammation, stiffness, and pain in the knee joint. The most common type is knee osteoarthritis, which results from cartilage degeneration over time. Rheumatoid arthritis, an autoimmune disorder, can also affect the knee, leading to swelling and damage to the joint lining. In some cases, past injuries or genetic factors contribute to developing knee arthritis.

Causes of Knee Arthritis

There are several factors that contribute to arthritis knee pain, including:

  • Aging and natural cartilage wear
  • Previous knee injuries
  • Excess weight putting stress on the joint
  • Genetic predisposition
  • Autoimmune conditions like rheumatoid arthritis

Symptoms of Knee Arthritis

Knee arthritis symptoms often develop gradually and worsen over time. These may include:

  • Persistent knee pain that worsens with activity
  • Swelling and stiffness, especially in the morning
  • Decreased range of motion
  • Cracking or grinding noises in the joint
  • Weakness or instability in the knee

How is Knee Arthritis Diagnosed?

A specialist will diagnose knee arthritis through a physical examination to assess joint movement, swelling, and tenderness. 

Imaging tests, such as X-rays or MRIs, help evaluate the extent of cartilage damage and rule out other conditions. 

Blood tests may be used to detect inflammatory arthritis, such as rheumatoid arthritis.

Treatment Options for Knee Arthritis

Treating knee arthritis involves a combination of non-surgical and surgical options, depending on the severity of the condition.

Non-Surgical Treatments

Many patients find relief through conservative treatments, including:

  • Physical therapy to strengthen muscles and improve flexibility
  • Anti-inflammatory medications to reduce pain and swelling
  • Corticosteroid injections for temporary relief
  • Wearing supportive braces or using assistive devices
  • Lifestyle modifications, such as weight management and choosing low-impact exercise over high-impact.

Surgical Treatments

If conservative treatments fail to provide relief, surgical options may be considered:

  • ArthroscopyA minimally invasive procedure to remove damaged cartilage
  • Partial knee replacement – Replaces only the damaged part of the joint
  • Total knee replacement – Replaces the entire knee joint with an artificial implant

Prognosis and Long-Term Outlook

The long-term outlook for knee arthritis depends on the severity of joint damage and how well treatment is followed. While osteoarthritis of the knee is a progressive condition, early intervention can help slow its progression and improve mobility. With proper care, including physical therapy and lifestyle adjustments, many patients successfully manage their symptoms and maintain an active lifestyle.
