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.

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.

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.
