The Achilles tendon connects the calf muscles to the heel bone and is the main structure that allows you to push off when walking, running, jumping, and changing direction. When it ruptures, people often describe a sudden snap or being “kicked” in the back of the ankle, followed by weakness and difficulty walking.
Surgery is commonly recommended for complete ruptures, particularly in physically active people, as it lowers the risk of re-rupture and helps restore strength more predictably.
Healing and Rehab Timelines
These are estimates. Everyone heals differently based on age, general health, activity level, and how the rehab is progressed.
First 2 weeks
The leg is usually immobilised in a cast or boot. Weight-bearing is often limited or avoided. Swelling, stiffness, and pain are expected.
Weeks 2 to 6
Gradual introduction of partial weight-bearing in a walking boot. Early controlled ankle movement may begin under guidance. The tendon is still vulnerable at this stage.
Weeks 6 to 12
Progression to full weight-bearing usually begins. The boot is slowly phased out. Strength work for the calf starts gently. Walking becomes more comfortable, but the tendon is not yet strong.
3 to 6 months
Strength, balance, and control continue to improve. Many people can return to normal daily activities and light gym work. Jogging may be introduced later in this phase for some patients.
6 to 12 months
Return to higher-impact sport, sprinting, and jumping is usually considered in this window. Full confidence and strength often take close to a year to return.
Even after the tendon has physically healed, the calf muscle often feels smaller, weaker, and slower to respond. Stiffness in the ankle is common. Swelling at the end of the day can persist for months. These are all normal parts of recovery and don’t mean the surgery has failed.
The tendon heals faster than the strength returns. Feeling “normal” does not mean the tendon is ready for high-speed sport. Rushing rehab is one of the biggest risk factors for long-term weakness or re-rupture. Confidence usually lags behind physical healing, especially in athletes.
