Introduction to total hip replacement also known as hip arthroplasty 

Total hip replacement, also known as total hip arthroplasty, is a surgical procedure in which the damaged or worn-out hip joint is replaced with an artificial joint (prosthesis) made of metal, ceramic, or plastic components.
The surgery aims to alleviate pain, improve mobility, and restore function in patients with hip joint disorders such as coxarthritis and coxarthrosis. This article will provide an informative overview of total hip replacement, including its indications, benefits, and risks, while highlighting the differences between coxarthritis and coxarthrosis.

Coxarthritis vs. Coxarthrosis: Understanding the Differences

Arthritis is an inflammatory condition involving one or more joints throughout the body that causes pain, swelling, and warmth in the affected areas. In contrast, arthrosis is a non-inflammatory degenerative condition associated with aging. Two common medical conditions affecting the hip joint are coxarthritis and coxarthrosis.

  1. Coxarthritis: This term refers to inflammation of the hip joint, which can be caused by various factors. The most common causes of coxarthritis are autoimmune diseases like rheumatoid arthritis, infections, and trauma. Symptoms of coxarthritis include pain, swelling, warmth, and stiffness in the hip joint, which may lead to a reduced range of motion.
  2. Coxarthrosis: Coxarthrosis is a degenerative joint disease caused by the progressive wear and tear of the hip joint's cartilage. The wearing down of cartilage results in pain, stiffness, and reduced range of motion. The primary causes of coxarthrosis are age-related wear and tear, obesity, genetic predisposition, previous injuries or fractures, and joint abnormalities.

Indications for Total Hip Replacement

Total hip replacement may be recommended for patients with coxarthritis or coxarthrosis in cases where conservative treatments, such as medication, physical therapy, or walking aids, have failed to provide adequate pain relief and functional improvement. Typical indications for the surgery include:

  1. Severe pain: Persistent and debilitating hip pain that significantly impairs daily activities and quality of life.
  2. Reduced mobility and function: Significant limitation in daily activities, such as walking, climbing stairs, or getting in and out of chairs, due to hip joint stiffness and pain.
  3. Advanced disease: Severe joint damage or deformity caused by coxarthritis or coxarthrosis that has not responded to conservative treatments.


Benefits and Risks of Total Hip Replacement

Benefits of total hip replacement surgery generally include:

  1. Pain relief: Most patients experience significant pain relief after surgery, leading to improved quality of life.
  2. Improved mobility and function: Total hip replacement can help restore normal hip joint function, enabling patients to regain their ability to perform daily activities more comfortably.
  3. Enhanced joint stability: Replacing the damaged joint with a prosthetic one can help provide increased stability and support.

Total hip replacement risks

However, like any surgical procedure, total hip replacement also carries some risks, which may include:

  1. Infection: Although rare, infections can occur after surgery and may require additional treatment or surgery.
  2. Blood clots: Blood clots can form in the leg veins after surgery, potentially leading to life-threatening complications if they travel to the lungs.
  3. Dislocation: The artificial hip joint can sometimes dislocate, requiring further intervention.
  4. Loosening of the implant: Over time, the artificial joint may loosen, which might necessitate additional surgery.
  5. Nerve injury: Nerves around the hip joint can be damaged during surgery, potentially causing numbness or weakness in the affected area.
