Final answer:
When rehabilitating the knee complex muscles, it is generally recommended that the quadriceps and hamstrings should be relatively equal in strength to maintain balance and prevent muscle imbalances.
Step-by-step explanation:
When rehabilitating the knee complex muscles, it is important to consider the strength goals of the quadriceps compared to the hamstrings. The quadriceps and hamstrings are two sets of muscles that work together to move the legs back and forth. However, they have different functions: the quadriceps extend the knee, while the hamstrings flex the knee. In order to maintain balance and prevent muscle imbalances, it is generally recommended that the quadriceps and hamstrings should be relatively equal in strength.
