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.

Return to Work (Restrictions / Accommodations)


Individuals whose jobs require prolonged standing may need temporary reassignment to sedentary duties. Some individuals may be instructed to wear a protective brace to facilitate healing. Limitations on how much weight may be borne by the affected leg will restrict walking and climbing and may necessitate the use of crutches, a walker, or cane. If assistive devices are prescribed, relocation to an accessible area of the workplace may be required, along with additional safety precautions. Individuals should avoid squatting, crawling, or kneeling. They may need frequent rest periods that allow for elevation of the lower leg. Other activities that need to be avoided include jumping, twisting, heavy lifting, pushing, or lunging. Company policy on medication usage should be reviewed to determine if pain medication use is compatible with job safety and function. Individuals whose injuries do not require surgical repair or reconstruction may nonetheless need time off from work to undergo extensive physical therapy to regain function. If an individual does require surgery, squatting, kneeling and crawling may need to be limited permanently.
