Tendon injuries primarily affect muscle strength because tendons connect muscles to bones, allowing for movement and stability of the joints. When a tendon is injured, it can weaken the muscle's ability to contract effectively, which directly impacts muscle strength. The capacity of the muscle to produce force and support movements is compromised.

In contrast, the other options like bone integrity, joint flexibility, and ligament stability may experience secondary effects due to the muscle's compromised function but are not the primary focus of tendon injuries. Bone integrity mainly concerns the health of the bone structure itself, joint flexibility deals with the range of motion within a joint, and ligament stability pertains to the connections between bones at a joint. Tendon injuries disrupt the ability of the muscle to function optimally, leading to decreased muscle strength as the primary consequence.
