Factors Influencing Duration

Factors influencing length of disability depend on the nature of the derangement, fitness level and age of the individual, intervention requirements, adherence to a rehabilitation program, proper rest interval, job requirements, the development of complications, and the presence of comorbid conditions or prior injury to the knee. Any task that stresses an already compromised knee will prolong and exacerbate the problem.
