What is Hip Osteoarthritis?

Hip osteoarthritis is a type of arthritis that affects the hip joint. It is a chronic condition that develops over time due to wear and tear on the joint. The hip joint is a ball-and-socket joint, made of the femur head (ball) and the acetabulum (socket). The hip joint is designed to provide stability and support to the body, as well as to allow for a wide range of motion.


When hip osteoarthritis occurs, the cartilage that covers the ends of the bones in the hip joint begins to break down. This causes the bones to rub against each other, leading to pain, stiffness, and reduced mobility. As the condition progresses, the bones may also develop bone spurs, which can further damage the joint.

Symptoms Of Arthritis In Hips

The symptoms of hip osteoarthritis can vary from person to person, but some of the most common symptoms include:


Pain in the hip joint, which may be felt in the groin, thigh, or buttocks


Stiffness in the hip joint, especially after sitting or lying down for a long period of time. Stiffness affects both flexion and extension as well as rotation of the hip joint.

Reduced range of motion

Reduced range of motion in the hip joint, making it difficult to perform everyday activities such as walking or climbing stairs. This leads to reduced quality of life.

Grinding or clicking sensation

A grinding or clicking sensation in the hip joint.


Swelling or tenderness around the hip joint

Diagnosing Hip Osteoarthritis

If you are experiencing symptoms of hip osteoarthritis, your doctor may perform a physical exam to assess your range of motion and detect any areas of tenderness or swelling around the hip joint. Your doctor may also order imaging tests such as X-rays or MRI scans to get a better look at the hip joint and assess the extent of the damage.

Non-Surgical Treatment Options For Hip Osteoarthritis

The choice of treatment will depend on the severity of the condition and the individual patient’s needs and preferences.
Your hip osteoarthritis specialist may recommend non-surgical treatments such as:

  • Lifestyle changes, such as losing weight or modifying activities to reduce stress on the hip joint
  • Physical therapy can help improve the range of motion and reduce pain and stiffness in the hip joint. Physical therapy also strengthens the hip muscles especially the hip abductors and buttock muscles which provides dynamic stability to the hip joint.
  • Medications, such as pain relievers or anti-inflammatory drugs, help manage pain and inflammation
  • Injections of corticosteroids or hyaluronic acid into the hip joint to reduce pain and inflammation

Surgical Treatment Options For Hip Osteoarthritis

If non-surgical treatments are not effective in managing hip osteoarthritis, your doctor may recommend surgery. Some of the surgical options for hip osteoarthritis include:

  • Hip resurfacing surgery, which involves replacing the damaged surface of the hip joint with a metal implant. This is less commonly performed now.
  • Osteotomy, which involves reshaping the bones in the hip joint to improve alignment and reduce stress on the joint
  • Hip replacement surgery, which involves replacing the entire hip joint with an artificial joint. This is made of biocompatible materials such as meta alloys, polyethylene and or ceramics.

Hip Replacement Surgery

Hip replacement surgery is a common procedure for severe hip osteoarthritis. During the surgery, the damaged hip joint is removed and replaced with an artificial joint made of metal alloys, plastic (polyethylene), or ceramic.

The procedure typically takes two to three hours, and patients typically stay for 1 to 2 days in the hospital to recover before discharge with enhance recovery protocols.

Hip replacement surgery is performed when sufficient conservative management has failed to alleviate symptoms and quality of life is adversely affected by the painful and stiff arthritic hip joint.

Hip replacement surgery is generally a very rewarding surgery with a high success rate in the appropriate patient. A successful and well executed hip replacement alleviates pain, improves mobility and grants a better quality of life.

When is the Best Time for Hip Replacement Surgery?

  • According to a study published in the Bone & Joint Journal, the best time for hip replacement surgery is when your hip osteoarthritis symptoms have reached a point where they significantly impact your daily life, and conservative treatments such as physical therapy and pain medication no longer provide relief. Delaying surgery beyond this point can lead to further joint damage, muscle weakness, and increased risk of complications.
  • The New England Journal of Medicine revealed that patients who underwent hip replacement surgery earlier in the progression of their hip osteoarthritis experienced better long-term outcomes. Improved mobility, reduced pain, and a lower likelihood of needing additional surgeries are some of the benefits of timely intervention.
  • The American Academy of Orthopaedic Surgeons recommends scheduling your procedure when you’re in good overall health and have a strong support system in place.

The best time for hip replacement surgery is when your symptoms become debilitating and non-surgical treatments are no longer effective. Prioritizing early intervention and ensuring a conducive environment for recovery are key factors in maximizing the benefits of this life-changing procedure. Consult with a qualified orthopaedic surgeon to learn more about your options.

Understanding The Causes Of Hip Osteoarthritis

There are several factors that can contribute to the development of hip osteoarthritis. One of the most common causes is simply aging. As we get older, the cartilage in our joints begins to wear down, which can lead to the development of osteoarthritis. Other factors that can contribute to hip osteoarthritis include genetics, obesity, previous injuries or surgeries, and certain medical conditions such as rheumatoid arthritis and avascular necrosis.

Recovery After Hip Replacement Surgery

Full recovery after hip replacement surgery can take several weeks, depending on the individual patient’s condition and the extent of the surgery. During the recovery period, patients will need to follow a rehabilitation program to regain strength and mobility in the hip joint. This may include physical therapy, exercises, and other measures to manage pain and inflammation.
