There are other knee ligaments injuries but the most common injury associated with instability at the knee is ACL injury (Chaudhari, 2008). Perhaps this is because of the fact that ACL injury presents quite a number of ways through which it can suffer tears. Research has shown that the most common ACL injury occurs when the knee is bent exceedingly to the or to the sides more than it is used. Such scenarios are highly likely to occur amongst sports persons during trainings when they engage in activities aimed at making them flexible. In other instances, ACL injury may also occur when there is a direct pressure exerted on the thigh at a time when a person is standing on one leg (Tiidus, 2008).
Studies have also revealed that ACL injury may also occur when a victim makes abrupt stop from a significantly highly speed, or attempts to make a sudden turn to the side while on a significantly high-speed motion. In all the above instances, one may observe that they all tend to exert pressure to the sides or on the ligaments at the back of the leg as had been noted. It is not a straightaway guarantee that any of such movements will result in ACL injury, but that they put a person at a highly risk of suffering from ACL injury. Therefore, there is a need to advise persons that take part in physical activities quite often on how what precautions to take during active periods of activities (Chaudhari et al., 2008).
However, many physiotherapists and health professions have researched and proposed various ways for recovery and rehabilitation for detected cases of ACL injury. The thesis statement of this research shall be: Appropriate response to ACL injury should be case specific rather than universal approach for recovery and rehabilitation. This research shall assess various cases and analyze each depending on its magnitude.
