Expert assessment and treatment of knee arthritis

The surfaces of the knee joint are covered with cartilage, a smooth, flexible material that allows the bone surfaces to move easily over one another.  If this cartilage becomes damaged, as a result of the degenerative changes associated with ageing, traumatic injury or disease, the resultant friction and rubbing in the joint causes the bone destruction associated with arthritis. 

Mr Auld offers expert assessment of arthritic symptoms such as knee pain and swelling.  In many cases he is able to manage the condition non-surgically using treatments such as  physiotherapy, painkillers and other medication, cortisone injections and advice on lifestyle changes.  In cases where these types of treatment fail to have an impact, or the joint is very badly damaged affecting day-to-day activities, he may recommend replacement of part, or all, of the knee joint with an artificial implant.

Knee replacement surgery in Northamptonshire

Knee replacement surgery, also known as arthroplasty, is now a routine operation in the UK, with more than 70,000 being carried out each year, mostly in people over 65.  A specialist in knee replacement surgery, Mr Auld is able to offer a range of procedures and implants depending on the nature of the damage to the joint:

Total knee replacement surgery

Total knee replacement (TKR) involves replacing the whole of the knee joint.  The worn ends of the thigh bone and the shin bone are cut away and the end of the thigh bone is replaced with a curved piece of metal and the end of the shin bone is replaced with a flat metal plate.  The implant is fixed in place with a special 'cement' that encourages the remaining bone to fuse with the components of the implant.  A plastic spacer between the metal surfaces reduces the friction in the joint.  Most commonly performed in cases of severe osteoarthritis, a TKR can bring relief from pain for up to 20 years.

Partial knee replacement surgery

Partial knee replacement (PKR) or unicompartmental knee replacement is a procedure to replace a localised area of damage in the knee joint.  Suitable for around 25% of people with knee arthritis, it is a less invasive operation compared to TKR, involving a smaller incision and less bone removal.   In some cases it may also result in a better range of movement compared to TKR.

Kneecap replacement

Where only the kneecap has been affected by arthritis, it may be resurfaced in a procedure known as patellofemoral replacement.  Involving less major surgery than TKR, kneecap replacement surgery preserves the unaffected areas of the knee joint.
