Achilles tendon ruptures are sometimes easily missed, or the patient simply does not feel a great impact and does not seek medical attention at all, and by the time it is discovered the best time for surgery is missed. The result is a defect or stiffening of the tendon, and the heel cannot be lifted normally on one foot, and is even prone to repeated strains, sprains, and pain. A number of patients have used transplantation of someone else’s tendon to repair it, but some of them end up having rejection reactions, resulting in the eventual loss of a relatively expensive tendon. In fact, in my personal experience, most patients with old ruptures in general can apply their own tissue for repair with minimal trauma and quick recovery, rejection is no longer present, and the chance of infection is very small. Most importantly, it is usually possible to obtain a largely complete restoration of bouncing function. Of course, the timing of the surgery and a good individualized preoperative evaluation will have the most important impact on the outcome. The surgeon can develop the most reasonable surgical plan based on the patient’s specific disruption and scarification, and the patient can often get the maximum good outcome at the minimum cost. However, there is also a fairly important correlation between full recovery and the post-operative rehabilitation plan and process. Careful rehabilitation, reasonable calf muscle strength exercises and gradual physical activity in accordance with medical advice is generally required to maximize the best functional recovery. But back to what was said earlier, even if the Achilles tendon is old and ruptured, do not be too anxious, as it is usually possible to obtain a largely complete functional recovery with reasonable surgery to help you return to the normal or near normal life you used to lead.
