A 41-year-old member asked:

Can you tell me are knees that naturally hyperextend more prone to injury (acl tears, mensical tears, patellar dislocations)?

Yes: Knee hyper extension is usually due contractures of the hamstring muscles, the calf muscles, or both. When these muscle groups are tight the knee hyperextends and the ankle doesn't dorsiflex enough. These two mechanical issues put a person at greater risk of both knee and ankle injuries.

Are knees that naturally hyperextend more prone to injury (acl tears, mensical tears, patellar dislocations)? I'm really worried.

Yes.: Generally speaking, yes, hyperextending knees create more knee joint laxity, and the more laxity there is, the more prone you are to all those things you mentioned. Stay fit and keep your lower extremities strong. It's the best thing to do to prevent injury.
