Total Hip Replacement
Total hip replacement involves replacing the damaged parts of the hip joint with metal and plastic components, significantly reducing pain and improving function for patients with severe arthritis or joint damage.

The surgery itself is painless due to anaesthesia, but post-operative pain and discomfort are expected. Pain management and physiotherapy are crucial parts of recovery.
Total hip replacement is very effective for severe hip conditions. Most patients experience significant pain relief and improved function, allowing them to return to their daily activities.
A total hip replacement is designed to provide long-term relief from pain and restore mobility, often lasting for many years. Modern implants are made from durable materials such as titanium, ceramic, or highly cross-linked polyethylene, which are engineered to withstand daily activities. On average, studies show that more than 90% of hip replacements continue to function well after 15 to 20 years. Many patients enjoy excellent outcomes for even longer, particularly when they follow their surgeon’s post-operative advice and maintain an active yet low-impact lifestyle. Factors that influence longevity include age, weight, activity level, and bone quality. Younger patients who are more physically active may experience greater wear over time, potentially shortening the lifespan of the implant. However, advances in surgical techniques and implant design have improved durability significantly, meaning most patients can expect their artificial hip to last for decades. Regular follow-up appointments help monitor the condition of the replacement and detect any early signs of wear or loosening. Maintaining good general health, avoiding smoking, and keeping a healthy body weight can further extend the life of the prosthesis. For many individuals, a well-performed hip replacement provides lasting comfort, stability, and improved quality of life.
Recovery following a total hip replacement is a gradual process that varies depending on the individual’s age, overall health, and pre-surgery mobility. In the hospital, patients usually begin moving within a day of surgery with the assistance of physiotherapists. Early movement is encouraged to reduce stiffness and improve circulation. Most patients use a walking aid such as a frame or crutches for several weeks. Pain and swelling are normal during the initial phase, but these typically improve with medication, rest, and gentle exercises. The first six weeks are critical for regaining strength and range of motion. Physiotherapy focuses on restoring balance, coordination, and confidence in walking. By three months, many patients can walk independently and perform most daily activities. Full recovery can take six months to a year, depending on fitness and dedication to rehabilitation. Patients are advised to avoid high-impact sports but can safely enjoy low-impact activities such as swimming, cycling, or walking. It is also important to follow all postoperative instructions, including wound care and attendance at follow-up appointments. Recovery requires patience and persistence, but with proper guidance and rehabilitation, most individuals return to an active and pain-free lifestyle.
The goal of total hip replacement is to restore comfort, stability, and improved range of motion. Many patients experience a significant improvement in flexibility compared to their preoperative state, especially if arthritis or injury previously caused stiffness. However, regaining a completely full range of motion like that of a natural, healthy hip may not always be possible. The final outcome depends on several factors, including the degree of joint damage before surgery, muscle strength, scar tissue formation, and adherence to rehabilitation exercises. During recovery, physiotherapy plays a vital role in improving mobility through targeted stretching and strengthening routines. Most patients can comfortably bend their hip to sit, tie shoes, or walk up stairs without pain. Activities such as crossing legs or deep squatting may be limited to protect the implant and prevent dislocation. Patients who stay active and maintain flexibility often achieve better long-term function. Surgeons aim to position the implant in a way that maximises movement while maintaining joint stability. Although some limitations remain, most people find that their new hip allows them to perform daily tasks with ease and engage in many recreational activities without restriction or discomfort.
A second surgery, known as a revision hip replacement, is sometimes required if the original implant wears out, loosens, or becomes infected. Fortunately, with modern techniques and materials, the need for revision has decreased considerably. Most hip replacements last 15 to 20 years or longer, meaning many patients never require another operation. Younger, more active individuals may eventually need revision surgery later in life due to natural wear and tear. Other reasons for revision include dislocation, fracture around the implant, or persistent pain. Regular follow-up appointments help detect early changes before symptoms worsen. When revision surgery is needed, it tends to be more complex than the first operation and requires careful planning. However, outcomes are generally very good, and many patients regain stable, comfortable function. The best way to reduce the likelihood of needing a second operation is to maintain a healthy lifestyle, avoid high-impact activities that stress the joint, and promptly report any unusual symptoms such as pain, swelling, or instability. Advances in implant technology and surgical precision continue to extend the lifespan of hip replacements, reducing the chances of requiring another procedure in the future.
Total hip replacement surgery typically takes between one and two hours, although this can vary depending on the surgical approach, the patient’s anatomy, and whether the procedure is straightforward or more complex. The operation is performed under general or spinal anaesthesia, ensuring the patient is comfortable throughout. The surgeon begins by making an incision to access the hip joint, then removes the damaged bone and cartilage before placing the new prosthetic components. Precision is essential to ensure correct alignment and secure fixation of the implant, which helps restore smooth, stable movement. In some cases, minimally invasive or anterior approaches can slightly reduce surgical time and aid faster recovery, but safety and accuracy remain the top priorities. After the procedure, the patient is taken to the recovery area for monitoring as the anaesthetic wears off. The total time in the operating theatre, including preparation and closure, may be slightly longer than the surgical portion itself. Despite its technical complexity, hip replacement is a routine operation for experienced orthopaedic surgeons, and modern advancements have made it safer and more efficient than ever before.
The recovery process after a total hip replacement involves several stages and focuses on restoring strength, flexibility, and confidence in movement. Initially, patients spend a few days in hospital, where they receive pain relief and are encouraged to begin walking with support soon after surgery. Early mobilisation helps prevent complications such as blood clots and stiffness. Physiotherapists guide patients through gentle exercises designed to improve circulation and rebuild muscle control. Once home, continuing a prescribed rehabilitation program is crucial. Over the first six weeks, the emphasis is on gradually increasing walking distance and performing strengthening exercises. Swelling and fatigue are normal during this time but improve steadily. By three months, most individuals regain independence and can return to many regular activities, including light work or driving. Ongoing physiotherapy may continue for up to a year to maximise recovery and ensure optimal hip function. Maintaining a healthy weight, avoiding smoking, and following the surgeon’s advice help achieve the best long-term results. The recovery process requires patience and commitment, but most patients experience lasting improvements in comfort, mobility, and overall quality of life.
Like any major surgical procedure, total hip replacement carries some risks, although serious complications are uncommon. Potential risks include infection, blood clots, dislocation, leg length difference, nerve or blood vessel injury, and implant loosening over time. Infections can occur around the incision or deeper near the prosthesis, requiring medical treatment or, in rare cases, further surgery. Blood clots in the legs are minimised through early mobilisation, medication, and compression devices. Dislocation risk is reduced by careful implant positioning and following movement precautions after surgery. Some patients may notice a slight difference in leg length, which usually resolves with time or shoe adjustments. Modern surgical techniques and improved implant design have significantly reduced complication rates. Preoperative assessment helps identify and manage factors such as diabetes, obesity, or heart conditions that may increase risk. Surgeons and medical teams take great care to maintain sterile conditions and use advanced technology to ensure safe, accurate placement of implants. While no operation is entirely risk-free, the benefits of pain relief, improved mobility, and restored independence usually far outweigh the potential complications when performed by an experienced orthopaedic surgeon.
Most modern hip replacements are designed to last 15 to 20 years or more, and many continue functioning well beyond that timeframe. Longevity depends on several factors, including the type of implant, surgical accuracy, patient age, body weight, and activity level. Newer materials such as ceramic-on-ceramic or highly cross-linked polyethylene have greatly improved wear resistance, reducing the rate of deterioration. Gentle, low-impact activities like walking, swimming, or cycling place minimal stress on the artificial joint and help it last longer. Conversely, high-impact sports or heavy lifting may accelerate wear. Regular follow-up with an orthopaedic surgeon allows early detection of any loosening or wear before it causes discomfort. Maintaining a healthy lifestyle also supports the durability of the implant. Many patients who undergo surgery in their 60s find their hip replacement continues to function well for the rest of their lives. While eventual wear is possible, revision surgery can restore function if needed. Overall, total hip replacement remains one of the most successful operations in modern medicine, offering long-term relief from pain and allowing people to stay active and independent for many years.
