Patient question

I was told I need PCL surgery after my accident, but I read most PCL tears heal. Why me?

Dr. Pablo GelberOrthopaedic Knee Surgeon

Quick answer

Most isolated PCL tears heal with a brace and rehabilitation, but surgery is usually advised when the PCL tear comes with injury to the posterolateral corner or other ligaments, when bone has pulled off with the ligament, or when a complete tear leaves the knee unstable. Dr. Pablo Gelber explains the reasoning at Aman Hospital in Doha.

Why accidents are different

Road traffic and motorcycle accidents in Qatar often involve far more force than a sports fall. That energy rarely stops at one ligament. The posterolateral corner, the group of structures on the outer back side of the knee, is commonly injured together with the PCL, and these structures heal poorly on their own when badly torn.

When both are injured, treating only the PCL with a brace tends to leave the knee loose and rotating abnormally, which also puts any later PCL repair at risk.

Common reasons surgery is recommended

  • PCL tear combined with a posterolateral corner, medial ligament or ACL injury
  • A bony avulsion, where the PCL has pulled off a fragment of bone that can be fixed back
  • A complete grade III tear with large backward movement in an active person
  • Persistent instability or pain after a good period of rehabilitation
  • A knee dislocation, where several ligaments are torn at once

Why timing matters

For combined injuries, outer corner structures are often more easily addressed within the first few weeks, when tissue is easier to identify and repair. That is why your surgeon may move faster than you expected. Other injuries from the accident, wound healing and swelling are taken into account in setting the date.

Questions to ask at your consultation

Ask which structures are torn, what would happen with non-surgical treatment, whether everything will be done in one operation, and what the brace and rehabilitation plan will look like. If you are unsure, a second opinion is reasonable. Dr. Gelber reviews the MRI with you and explains why each part of the operation is suggested.

Frequently asked questions

Can I try a brace first and decide later?

For an isolated PCL tear, often yes. For combined injuries, delaying can make later reconstruction more complex, so the risks and benefits of waiting are discussed individually.

Will I need more than one operation?

Many combined injuries are reconstructed in one operation. Occasionally a staged approach is chosen because of swelling, wounds or other injuries from the accident.
