FAQs for Knee Replacement
These are some commony asked questions for Knee replacement surgeries

Can I return to playing sports after my total knee replacement ? You can return to playing low-impact sports. This means sports that don’t put high stresses on your knee. These include golf, bowling, cycling or swimming. 

When will I experience the full benefit from surgery ? Although you will experience relief of your pre-operative pain quite soon after the operation, the return of full function can take much longer. After three months, you will probably have regained some of the strength in the muscles around the knee, and range of movement will be improving. However, it may take up to 18 months to feel the full benefits. 

When will I be able to drive ? You are able to drive 6 weeks after the operation, providing there have been no problems in your rehabilitation. If you have an automatic car, and have had a left knee replacement, you could return to driving once the wound is healed, which is usually around 2 weeks post op. 

How long will my joint replacement last ? Research shows at 10 years 97% of knees are functioning satisfactorily this reduces to 95% at 15 years and 70% at 20 years. 

When will I be able to fly? You are able to fly no sooner than three months after your operation. Your risk of having a DVT (clot in the calf) is still high within this time period. 

Will I set off the alarm at the airport ? The prosthesis is made of titanium and cobalt chrome and, in theory, shouldn’t set off the alarms. If the alarm does go off, then the scar on your knee will help confirm that you have had knee surgery. If you are worried then you could ask your consultant for a letter to confirm you have had a joint replacement. 

Is it normal for my knee to make a noise when I move it ? Yes. This is the metal and plastic components moving over each other.

Can I kneel after my knee replacement ? A third of patients find this is difficult and painful to do following this type of surgery. Kneeling on hard surfaces is not recommended but special kneeling mats can sometimes help. 

Will any further surgery be required ? On a few occasions, some patients may find their knee is very stiff even though they have tried hard to get it to bend. Your surgeon may then recommend a manipulation. This involves going back to theatre and being put to sleep again. The knee is then bent as far as it will go and you return to the ward. Your knee is then placed on a machine, which keeps the knee bending. There is no wound to heal like with the initial operation, but it is still hard work for you to maintain the movement that has been gained. Eventually, the knee replacement can wear out and another (revision) knee replacement may be needed. 

Will I be pain free ? The majority of patients may well be pain free and no longer need painkillers. About a third of patients will have some pain, but it should be much less than the pain they had before the operation.
