My mother needs to have knee replacement surgery. Would she be in a lot of pain afterwards?

Knee replacement is a major surgery, and discomfort is involved during the rehabilitation process. The patient should be prepared to manage the discomfort and to achieve the rehab goals under the guidance of their surgeon. Multimodal pain management protocols have dramatically improved pain after knee replacement surgery so that patients can walk day of surgery and be home the day after surgery, or even the same day as surgery in some cases.

My mother's hips are paining ever since she had the hip joint replacement surgery. Will this be permanent?

That is an unexpected result, and repeat evaluation, or second opinion would be warranted to make sure there is not a treatable cause of her continued pain. Workup would involve READ MORE
That is an unexpected result, and repeat evaluation, or second opinion would be warranted to make sure there is not a treatable cause of her continued pain. Workup would involve repeat xrays, possible lab work, physical exam. Evaluation sooner rather than later would be recommended to avoid it becoming a permanent problem.

How is a knee cap replacement surgery done?

If you are referring to partial knee cap replacement, it is resurfacing of the kneecap, and placing a metal groove for it to glide in when the knee bends. It is only "part" of READ MORE
If you are referring to partial knee cap replacement, it is resurfacing of the kneecap, and placing a metal groove for it to glide in when the knee bends. It is only "part" of a total knee replacement, with a much faster recovery and does not prohibit a total knee replacement later if necessary. I perform a high volume of these procedures because in the right person they can do very well. A 40 minute procedure and home same day.

My mother underwent a joint replacement surgery. How long will the recovery take?

Recovery from joint replacement can vary, depending on the physical health of the patient coming in to surgery. Typically, patients will get better and stronger for up to a year READ MORE

Partial knee replacement is addressing only one of the 3 compartments of the knee. In the properly selected patient, the results can be excellent. In some literature, even better than total knee replacement. However, the procedure is dependent on patient selection, and surgeon expertise. Otherwise, total knee replacement works very well also. Partial knee replacements can be converted to total knee replacement later, if necessary, but the goal is that it remains the one and only procedure, if at all possible.
