The amount of time it will take for you to get back onto your feet really depends on how bad the injury is as well as how long you have been experiencing the problem. . In general, you can expect to be back in shape and healthy again in four-to-six weeks after a knee injury. If you have surgery or a more serious sprain, then it will take longer for your recovery and healing process. The most important part is of course to work at your own pace. If you slack off, then you can easily become discouraged and give up; but if you push yourself, then you will see much better results.
Knee rehab is generally a short-term process that is necessary for any injury but must be followed through with a physical therapist in order to see the best results and return to normal life. This can be difficult for many people to navigate, especially because knee injuries are quite common and there are a number of different techniques and treatments that physical therapists can use on patients, each having its own advantages as well as disadvantages. Remember to visit a qualified physical therapist like one from a physical therapy clinic in order to get your knee rehab started.
