Anterior cruciate ligament (ACL) surgery replaces the damaged ligament with a new ligament called a graft. In most cases, the graft is a tendon taken from your own knee or hamstring. In some cases, the graft comes from a donor.
You will feel tired for several days. Your knee will be swollen, and you may have numbness around the cut (incision) on your knee. Your ankle and shin may be bruised or swollen. You can put ice on the area to reduce swelling. Most of this will go away in a few days. You should soon start seeing improvement in your knee.
You may be able to return to most of your regular activities within a few weeks. But it will be several months before you have complete use of your knee. It may take as long as 6 months to a year before your knee is ready for hard physical work or certain sports. Surgery can help. But even after surgery, your knee may not be as strong as it was before the injury. You will need to build your strength and the motion of your joint with rehabilitation (rehab) exercises.
How soon you can return to sports or exercise depends on how well you follow your rehab program and how well your knee heals. Your doctor or physiotherapist will give you an idea of when you can return to these activities. Most people can jog in about 4 months and run or cycle in about 4 to 6 months. You may need to wear a knee brace when you play sports.
