Introduction
Choosing the right type of hip replacement is a critical step in helping patients regain mobility and improve their quality of life. Two widely used surgical options—hemiarthroplasty and total hip replacement —each have their benefits and potential drawbacks. In this article, we’ll clearly compare these procedures, looking at how personal factors like age, lifestyle, and overall health can affect outcomes. The goal is to provide up-to-date, evidence-based information to help both patients and clinicians make confident, personalised choices.
Understanding the Procedures and Their Purpose
Hip replacement surgery is most often advised for conditions such as osteoarthritis or fractures near the top of the thigh bone (the femoral neck) that cause pain and restrict movement. Hemiarthroplasty replaces only the ball-shaped head of the femur, leaving the hip socket intact. Total hip replacement , on the other hand, replaces both the femoral head and the hip socket, fully reconstructing the joint.
Traditionally, hemiarthroplasty was recommended for older adults with lower activity levels due to its simpler and shorter surgery. With advances in surgical methods and materials, however, total hip replacement has become more reliable and suitable for a wider range of patients. The choice between these two procedures is increasingly guided by an individual’s specific needs and health profile.
How Do Patient Outcomes Compare?
To assess which procedure is right for each person, it’s essential to consider recovery time , pain relief, restoration of mobility, risk of complications, and long-term joint performance. Studies have shown that total hip replacement often provides better pain relief and a greater range of motion, making it ideal for younger or more active individuals. While the initial recovery may be slightly longer, many patients find the lasting improvement in joint function worth the investment.
Hemiarthroplasty, meanwhile, typically involves a shorter procedure and lower immediate surgical risk, which is important for elderly patients or those with significant medical concerns. However, because the socket is left in place, there’s a risk that it may wear out over time, sometimes leading to the need for additional surgery. Functional outcomes with hemiarthroplasty can be slightly lower than with total hip replacement , but the risk of hip dislocation is generally less.
Interestingly, results from a large study of nearly 1,500 patients found no significant difference in the number of follow-up surgeries or in mortality rates between the two procedures. Over two years, both groups experienced similar improvements in function and quality of life. This underscores that matching the surgical approach with individual patient factors—such as age, activity level, bone health , and overall wellbeing—is key to achieving the best outcome.
Surgical Insights and Considerations
From a surgical standpoint, hemiarthroplasty is often less invasive since it only involves replacing the femoral head . This reduced invasiveness can make it safer for patients who might not tolerate a longer or more complex operation. Total hip replacement , which replaces the entire joint, is more technically demanding and may carry a slightly higher risk of certain surgical complications, such as hip dislocation.
However, improvements in implant technology and surgical technique are making both procedures more effective and durable. Ultimately, the skill and experience of the surgical team are crucial in minimising risks and maximising the benefits of hip replacement . For some patients, the more comprehensive repair provided by total hip replacement may offer better long-term outcomes, but these advantages must be carefully weighed against each individual’s medical situation and personal preferences.
Conclusion
In the end, choosing between hemiarthroplasty and total hip replacement should be a personalised decision, taking into account each patient’s age, activity level, bone health, and overall risk factors. Total hip replacement tends to offer better long-term function and mobility, especially for active patients, while hemiarthroplasty remains a proven and safer option for those with higher surgical risks or lower activity demands. As surgical techniques and materials continue to advance, hip replacement care is becoming more tailored and effective than ever. By focusing on individual needs and up-to-date evidence, patients and clinicians can work together to achieve the best possible outcomes.

Frequently Asked Questions
Hemiarthroplasty involves replacing only the femoral head, whereas total hip replacement replaces both the femoral head and socket. Prof Lee and MSK Doctors will assess which procedure best matches your individual needs and lifestyle for optimal recovery.
Active, younger patients often gain better mobility and pain relief with total hip replacement. At MSK Doctors, Prof Lee uses advanced techniques to personalise surgery, aiming for the best possible joint function based on each person’s activity level and health.
Prof Lee at MSK Doctors provides extensive experience in hip replacements, utilising cutting-edge technology and evidence-based practice. Patients benefit from tailored care and highly specialised surgical skills, helping to reduce risks and optimise recovery outcomes.
Total hip replacement may involve a longer initial recovery, but offers greater long-term mobility for active patients. Hemiarthroplasty allows faster surgery, suiting those with higher surgical risks. Prof Lee personalises surgical recommendations, considering your long-term wellbeing and specific needs.
