Pain Under Buttock After Hip Replacement

Hip replacement surgery is a common procedure that aims to alleviate pain and improve mobility for individuals with severe hip joint deterioration. While the surgery offers promising outcomes, post-operative complications can arise, often causing discomfort and hindering the recovery process. Among these complications, individuals may experience pain under buttock after hip replacement surgery. 

This specific pain, located in the area where the buttock meets the thigh, can be both perplexing and distressing for patients. Understanding the causes and factors contributing to this pain is crucial for effective diagnosis and treatment.

In this article, we will explore the possible reasons behind the pain under the buttock after hip replacement, discuss diagnostic approaches, and highlight potential treatment options for relief and improved post-operative recovery.

Understanding Hip Replacement Surgery

Hip replacement surgery, a commonly performed procedure, aims to alleviate pain and improve mobility in individuals with severe hip joint deterioration. 

This surgical intervention involves the removal of the damaged or diseased parts of the hip joint and replacing them with artificial components. 

By restoring joint function, hip replacement surgery can significantly enhance a person’s quality of life.

The surgical procedure:

The surgeon removes the damaged portions of the hip joint, including the femoral head (the ball-shaped part) and the damaged socket (acetabulum). 

These are replaced with prosthetic components, typically made of metal, plastic, or ceramic materials, designed to replicate the natural hip joint.

Goals and benefits:

The primary goal of hip replacement surgery is to reduce pain, increase mobility, and restore joint function. 

By replacing the damaged hip joint, individuals can experience significant pain relief, allowing them to perform daily activities more comfortably.

 Additionally, improved joint function can enhance overall physical activity, leading to better overall health and well-being.

Common Complications After Hip Replacement

Hip replacement surgery, while generally safe and effective, can sometimes be associated with certain complications during the recovery period. 

It is important for patients to be aware of these potential issues to recognize and address them promptly. The following are common complications that can occur after hip replacement surgery:


Infections can occur in the surgical site or in the deeper tissues surrounding the hip joint. Symptoms may include fever, increased pain, swelling, redness, or drainage from the incision. Infections require immediate medical attention to prevent further complications.

Deep Vein Thrombosis (DVT):

DVT is the formation of blood clots in the deep veins, typically in the lower leg or thigh. Symptoms include swelling, pain, warmth, or redness in the affected leg. 

If a clot breaks free and travels to the lungs, it can cause a potentially life-threatening condition called pulmonary embolism. Blood thinners and early mobility after surgery help reduces the risk of DVT.

A dislocation occurs when the artificial hip joint becomes displaced from its normal position. This can cause severe pain and immobility. 

It is more likely to happen within the first few months after surgery. Precautions such as avoiding certain movements and using assistive devices can help prevent dislocation.

Implant Loosening:

Over time, the artificial components of the hip joint may loosen, causing pain, instability, and reduced function. 

This complication is more common in older implants or when the patient engages in high-impact activities. Revision surgery may be required to replace the loosened components.

Nerve Injury:

Nerves around the hip joint can be damaged during surgery, leading to numbness, tingling, weakness, or pain. 

Most nerve injuries improve over time, but in some cases, surgical intervention or specialized treatments may be necessary.

Leg Length Discrepancy:

In some instances, the length of the leg may be slightly altered after hip replacement surgery, resulting in a noticeable difference in leg length. 

This can cause gait abnormalities or discomfort. Customized shoe inserts or, in rare cases, revision surgery may be recommended to address this issue.
