Knee replacement, also known as knee arthroplasty or total knee replacement, is a surgical procedure aimed at addressing knee damage caused by arthritis. Metal and plastic components are utilized to cover the ends of the bones forming the knee joint, including the kneecap. This surgery is commonly advised for individuals experiencing severe arthritis or substantial knee injuries.
The knee joint can be affected by various types of arthritis. Osteoarthritis, a degenerative condition typically seen in middle-aged and older adults, results in the breakdown of joint cartilage and adjacent bone in the knees. Rheumatoid arthritis, characterized by inflammation of the synovial membrane and excessive synovial fluid, can lead to pain and stiffness. Traumatic arthritis, stemming from knee injuries, can cause cartilage damage.
The primary objective of knee replacement surgery is to address the damaged portions of the knee joint and alleviate knee pain that has not responded to other treatments.
Conditions that may necessitate knee replacement surgery include:
- Osteoarthritis
- Rheumatoid arthritis
- Post-traumatic arthritis
- Knee deformities
- Osteonecrosis or avascular necrosis
- Swelling or inflammation that does not decrease
Before undergoing knee replacement surgery, individuals may experience a range of signs and symptoms related to their knee condition, such as:
- Chronic Knee Pain
- Stiffness
- Swelling
- Reduced Range of Motion
- Instability
- Difficulty Walking
- Limited Functionality
Before undergoing total knee replacement (TKR) surgery, several diagnostic tests may be conducted to assess the extent of knee damage and to determine the appropriateness of surgery. These tests may include:
- Physical Examination
- X-rays
- MRI (Magnetic Resonance Imaging)
- Blood Tests: Blood tests may be performed to rule out underlying medical conditions that could affect surgery or recovery, such as infections or autoimmune diseases.
- Joint Aspiration (Arthrocentesis)
- Bone Scans
Post-knee replacement surgery, patients typically spend a few days in the hospital for monitoring and initial rehabilitation.
Pain management is crucial, with medications and physical therapy starting early to improve knee strength and mobility. Assistive devices like walkers may be needed initially, gradually phased out as mobility improves. Wound care and follow-up appointments ensure proper healing and monitor progress.
Long-term rehabilitation continues to optimize knee function and mobility, usually leading to significant improvement in pain and quality of life.
Perform knee-strengthening exercises that increase your muscle strength and mobility.
Try to Keep your wound clean and dry to prevent infection.
