Knee Replacement

Total Knee Replacement with West Sussex Orthopaedics

Knee replacement has now overtaken hip replacement as the most commonly performed joint replacement in the UK, with 98500 primary procedures performed in England and Wales in 2015. The damaged knee is replaced with an artificial joint, which usually improves pain and mobility.


Most knee replacements will last a lifetime but occasionally they can wear out or loosen, particularly in young or active patients. This may require revision surgery to replace the old components. Revision surgery may be considerably more complicated than primary surgery so the decision to undergo knee replacement (and joint replacement in general) should be carefully considered.


Mr da Assunção has subspecialty and fellowship training in primary and revision knee replacement surgery and only uses implants with a proven track record and good published long term outcomes. Mr da Assunção will discuss the pros and cons of surgery carefully with every patient and treatment decisions will always be tailored to the individual.


Total knee replacement is major surgery and complications can occur. Detailed information about the advantages and disadvantages of surgery are available in the Patient Information booklet for Total Knee Replacement.
