Knee Replacement Surgery

Knee replacement surgery is increasing exponentially, much more than other joint operations.

knee replacementThe most common age for women to have this operation is in their mid- 60s and it is similar for men but age can range from the 30s to the early 90s, Mr Edwards (Orthopaedic surgeon) states, and carrying extra weight can be a big cause.  Carrying extra weight gives a higher incidence of developing osteoarthritis.   However, genetic influences and trauma can also be reasons why people need knee replacement operations.  Knee replacement surgery is slightly more prevalent in women, he says.  That’s because there is a slightly higher predisposition in women to what we call primary arthritis, but it affects both males and females.

With knee replacement operation there is post – operative physiotherapy involved and usually it is quite painful, but there are few restrictions.  The success rate with knee replacements is approximately 85-90%.  A lot is down to the patient, you have to put the work into the rehab.


Patients are usually in hospital for 2-6 days when having a knee replacement operation. Patients are up and walking the day after the operation and walking up and down stairs before they leave hospital.  Following exercise instructions at home after the operation is really important.  Rehabilitation after the operation usually involves:

– using two crutches for two to four weeks

– concentrating on range of movement exercises at the knee to restore the knee function.

– strengthening exercises for the muscles around the knee joint, especially the quads muscle.

– balance work to progress safe walking.

– progressing to using a single crutch for two to four weeks.

– driving is not allowed for six weeks.

– farmers are allowed to ‘tip around’ on the farm eight weeks after the operation.

– tractor driving may be possible after eight to ten weeks.

– full farming duties may be resumed after twelve weeks.
