Joint replacement surgery is one of the most successful operations performed today. For many people, replacing a worn hip, knee or shoulder dramatically reduces pain and restores mobility. However, around 10–20% of people continue to experience persistent pain after joint replacement surgery. This can be confusing and distressing, particularly when X-rays show that the new joint is in the correct position and everything appears to have healed well. At Wye Sanctuary, we understand that persistent pain after joint replacement is a recognised medical condition. Understanding why it happens is the first step towards finding the right treatment.
Everyone experiences pain after surgery. This is a normal part of healing and usually improves over weeks or months. When pain continues for more than three months after surgery, after normal healing has taken place, it is known as persistent post-surgical pain. This does not automatically mean that something has gone wrong with your operation.
One of the most important things to understand is that pain does not always come from the artificial joint itself. Modern joint replacements are designed to last many years and are extremely reliable. Sometimes the joint is functioning perfectly, but pain is arising from the surrounding muscles, nerves or nervous system.
There is rarely one single explanation. Persistent pain is often caused by several factors working together.
Persistent nervous system sensitisation
Living with arthritis before surgery often means your nervous system has been processing pain for months or years. Although the damaged joint has been replaced, the nervous system can remain overprotective, continuing to produce pain even after healing has occurred.
Muscles and soft tissues
Major surgery affects muscles, tendons and ligaments surrounding the joint. Weakness, stiffness and altered movement patterns can all contribute to ongoing discomfort long after the operation itself has healed.
Nerve pain
Small nerves can occasionally become irritated or damaged during surgery. Burning pain, electric shock sensations, tingling, numbness or increased sensitivity around the scar may need different treatments from arthritis pain.
Scar sensitivity
Scars usually settle over time, but occasionally they remain unusually sensitive. Even clothing or light touch may become uncomfortable. Simple desensitisation techniques can often improve these symptoms.
Other joints and pain conditions
Replacing one painful joint can change the way you move, placing extra stress on the opposite hip or knee, lower back, feet or pelvic muscles. Fibromyalgia, chronic low back pain, peripheral neuropathy, tendon problems and bursitis may also continue after a successful joint replacement.
Could something be wrong with the replacement?
Occasionally, yes. Your orthopaedic surgeon will consider infection, loosening, instability, fracture, implant wear or malalignment. These problems are uncommon but important to identify because they may require specific treatment.
Assessment usually begins with a careful history and examination. Depending on your symptoms, investigations may include X-rays, CT scan, MRI scan for some joints, blood tests, ultrasound, bone scan, or joint aspiration if infection is suspected. The aim is first to exclude treatable mechanical problems before considering other causes of persistent pain.
Treatment depends entirely on what is causing the pain. It may include targeted rehabilitation to improve strength, movement and confidence; medication review, particularly where nerve pain is suspected; injection treatments into surrounding tendons, bursae or nearby joints; lifestyle medicine including sleep, activity, weight management and stress reduction; psychological support for fear, frustration and reduced confidence; and medical cannabis for carefully selected patients with chronic pain that has not responded to conventional treatments.
Yes. Many people continue to improve for 12–18 months after joint replacement surgery. Even when pain has persisted for longer than expected, understanding the cause allows treatment to be tailored more effectively. The goal is not simply to reduce pain, but to improve confidence, movement and overall quality of life.
Seek prompt medical assessment if you develop increasing redness around the joint, fever, wound discharge, sudden inability to bear weight, new deformity, severe swelling or rapidly worsening pain. These symptoms could indicate complications that require urgent assessment.
Persistent pain after joint replacement is rarely explained by one factor alone. Our approach is to look beyond the X-ray and understand how surgery, healing, muscles, nerves, sleep, lifestyle and the nervous system may all be contributing to your symptoms. Working alongside your orthopaedic surgeon, physiotherapist and GP where appropriate, we aim to identify the factors driving your pain and develop a personalised treatment plan that helps you regain confidence and improve your quality of life.
“One of the most difficult things for patients is hearing that their new joint ‘looks perfect’ while they continue to live with pain. It’s easy to feel dismissed or to wonder whether anyone believes you. Persistent pain after joint replacement is a recognised condition, and it deserves careful assessment. My role is to look beyond the implant itself and understand all the factors that may be contributing to your symptoms. By identifying these factors and working together on a personalised treatment plan, we can often help reduce pain, restore confidence and improve your quality of life.”
