...it is important to consider its relatedness to sports and activity an individual may participate in. Therefore, the inclusion of single-leg hops in functional tests improves the representation of physical demands an individual may experience in sports such as football. These protocols are more suitable to highlighting the instability of the injured limb, opposed to how other joints compensate (ref). Ref despite ACLr individuals with no signs of knee instability returning to sport, they still altered movements to protect the weakened limb. The concluding kinetic data highlighted ankle extensor muscles contributed greater than the ankle extensor muscles of an uninjured individual. Moreover, those still yet to return to sport, displayed a reduction in the range of motion about the knee joint, suggesting ACL remains stiffer throughout obtuse flexion and extension angles.

- Locomotion is the ability to move from one place to another. We use locomotion every day without even thinking about what we are doing. For most of us, walking is the main method of locomotion, it requires balance and could even be described as controlled falling. Taking just one step uses 200 muscles throughout the entire body and walking uses all the joints and muscles of the lower limb. "It is characterized by an ‘inverted pendulum‘motion, the body vaults over the non-moving limb."(The Functional Anatomy of Walking – Positive Health Online.) When humans walk, it usually consists of a repeated gait cycle.... [tags: Knee, Foot, Extension, Flexion]

- When an athlete catches the sound of their knee crack and pop, they better prepare themselves for a long journey. The Center for Injury and Policy (CIRP), from Science Daily, reports that, “Knees are the most accident prone part of the body in high school athletes.” Knee injuries are very common; in fact, they are responsible for 45% of the injuries that occur in high school athletics across America. Knee injuries are well known to not just those in the medical field, but also to athletes. Injuries to the knee are caused by many factors, and what happens after the injury has taken place is what’s most concerning (Science Daily).... [tags: Osteoarthritis, knee crack and pop]

- A total knee arthroplasty is indicated for an effective way to treat late stage arthritis in the knee. According to Trojani et alˡ two thirds of the patients who have a total knee arthroplasty (TKA) have the degenerative disease in both knees. Twenty percent of those patients will have to have surgery on the other knee within two years of having the first surgery.ˡ When the disease affects both knees the patient only benefits when both knees joints are replaced. With the appropriate patient, an orthopaedic surgeon may elect to do a simultaneous bilateral total knee arthroplasty where the patient undergoes a total knee replacement on both knees at the same time....
