Tibialis posterior tendinopathy, though not as commonly discussed as other musculoskeletal issues, plays a crucial role in maintaining the stability and functionality of the foot. This condition involves irritation of the tibialis posterior tendon, which runs along the inside of the ankle and foot. As this tendon is responsible for supporting the arch of the foot and controlling its movement during walking, any disruption can lead to significant discomfort and hinder daily activities.

One of the primary causes of tibialis posterior tendinopathy is overuse, often seen in individuals who engage in repetitive activities or sports that strain the tendon. Factors such as age, biomechanics, and lifestyle factors can also contribute to its development. Recognising the symptoms, which may include pain, swelling, and difficulty walking, is crucial for early intervention.

Treatment typically involves a combination of load management, physical therapy, and orthotic devices to support the foot's arch. Early detection and exercise therapy key to preventing the progression of this condition.
