The treatment of most medical conditions is complex and now involves such specialised techniques and equipment that diagnosis and treatment (surgical or non-operative) requires Medically Qualified Consultant Specialists of the highest calibre, with the best possible training. Our Consultant Specialists are nationally and internationally recognised in their individual fields at the highest levels for their extensive academic achievements. It is our belief that research and academic success are core to the ability to understand, lead and drive modern surgical services of the highest quality.
Specialist orthopaedic surgical procedures offered by our Consultants include:-
- knee arthroscopy
- hip arthroscopy
- knee replacements
- hip replacements
- revision surgery
The procedure of total hip replacement (THR) has been practiced for many years now, with excellent reported results. Modern hip replacements should be expected to last many many years, with in excess of 95% of the hips that we put in lasting more than 10 years.
THR involves removing the arthritic bone around a hip and replacing the joint with a new artificial bearing. The hip is a ball and socket joint, with the ball being at the top of the thigh bone (femur) and the socket (acetabulum) being in the side of the pelvis.

With a traditional hip replacement, the ball of bone (the femoral head) is cut away, and a metal stem is fixed inside the bone of the top of the femur. The metal is fixed into the bone with a special bone ‘cement’, made of an artificial substance called polymethylmethacrylate, which sets solid. A metal ball is then placed onto the top of the metal stem. The bone of the socket in the pelvis is then scraped out (reamed), and a polyethylene cup is cemented into the pelvis. The metal ball is then located into the new plastic cup, giving a good strong artificial ball and socket joint.
The results of hip replacements are generally excellent, with in excess of 95% of hip replacements still in place and working well after 10 years.
However, the operation itself should not be underestimated. It requires either a general or a spinal anaesthetic, and the surgery itself can last 1½ hours. Patients can, not infrequently, require blood transfusions after the surgery, due to the blood loss that inevitably occurs during the procedure. Patients are generally kept in hospital for something in the region of 5 – 10 days postoperatively, depending on their general fitness.
Different Types of Hip Replacement
Most traditional THRs use a special type of bone cement to fix the prostheses into the bone of the femur and the pelvis. However, there are many THRs available now that do not rely on cement, and which instead are press-fit into the bone. They are normally textured and/or coated with chemicals (hydroxyapetite) that encourage the bone to grow onto the surface of the prosthesis.
Some companies have developed hip replacements with harder bearing surfaces, such as ceramics or metal-on-metal. These each have their potential merits and potential problems. In the past there have been some concerns with the use of ceramic balls and sockets, where there were cases where the ceramics were too brittle and therefore cracked and broke. Modern ceramics, however, are more reliable and the wear rate with a ceramic-on-ceramic hip can be as much as 1000 times less than is seen in a traditional metal-on-plastic hip.
Northwood Sports Orthopaedics prides itself on the quality of its Specialists, the quality of the service provided to patients, and the quality of its results and outcomes. We provide an entirely patient-centred service from Specialists who have the deepest commitment to their patients.
