Knee replacement surgery is one of the specialised surgeries. For better results, after this procedure certain things patient must follow religiously.
We can divide it in four categories: 

1. Preoperative - Some changes at home like arrangement of commode/western toilet is must. If western toilet is not available then fold-able commode chair can be arranged. Also ,during immediate post operative period patient needs walker followed by  stick support for walking. So do arrange these things prior you get admitted for surgery. Medicines like clopitab /ecosprin must be stopped before one week of surgery or as per advised by your surgeon/physician .

2. During admission and post operative period - Follow all instructions given by your doctor. Do exercise and physiotherapy as per schedule. Eat lots of water and keep yourself hydrated. Take soft diet and small feeds after 3-4 hrs. If you are diabetic then keep a watch on sugar levels. If you have fever then immediately contact your surgeon and follow their guidelines.

3.Post operative at home - Physiotherapy exercises are important during post operative period to regain strength of thigh muscle. Also they help you to become independent from support of the walker. It trains you to climb chair and perform all your day to day activity at your own. Three months of physiotherapy after surgery not only makes you independent but help to regain maximum range of movement of your new joint.

4.Follow up - Regular follow up with surgeon every month for first 6 months and then every year is mandatory. Excessive activity ,over-activity, jogging ,trekking, must be avoided after surgery. Swimming cycling can be started with instructions of your surgeon. Walking is good exercise and that is more than enough for all the patients of this age group. Sitting cross-leg and squatting must be avoided. Patients with high flexion joints can sit cross leg  with consent of their surgeon.
