Patient question
Is multi-ligament knee surgery done in one operation or in stages?
Dr. Pablo GelberOrthopaedic Knee Surgeon
Quick answer
Both approaches are used. Many multi-ligament injuries are reconstructed in a single operation once swelling settles, often within the first few weeks, while others are staged, repairing the collateral side early and the cruciates later. The choice depends on the injury, the skin, any artery repair and knee motion, explains Dr. Pablo Gelber, surgeon at Aman Hospital in Doha.
What decides the timing
- Whether there was an artery injury, which must be repaired first and allowed to heal
- The state of the skin and swelling, as operating through swollen or damaged skin raises the risk of wound problems
- Which ligaments are torn and where, since collateral and posterolateral structures torn off bone are ideally repaired early
- Associated fractures, nerve injuries or injuries elsewhere in the body
- How well the knee is moving, because stiffness is a major risk after this surgery
Single-stage reconstruction
In a single operation, the cruciate ligaments are reconstructed arthroscopically and the collateral or posterolateral structures are repaired or reconstructed through open incisions. The advantage is one anaesthetic and one rehabilitation pathway. It suits patients whose knee has settled, whose tissues are healthy and whose surgery can be done within a reasonable time after injury.
Staged surgery
Staging spreads the work over two or more operations. A typical example is early repair of the outer-side structures, followed weeks to months later by ACL or PCL reconstruction once motion has returned. Very unstable knees, or those with artery repair, may first be held in an external frame. Revision cases with previous tunnels sometimes need bone grafting before reconstruction.
How the plan is made at Aman Hospital
Dr. Gelber reviews the emergency records, imaging and examination findings, then explains the proposed sequence, the grafts to be used and the expected rehabilitation. The aim is a stable knee with good motion, achieved in the safest order for that particular injury.
Frequently asked questions
What grafts are used?
Grafts may be your own tendons, donor tendons or a combination. Because several ligaments are rebuilt, donor grafts are often considered to avoid taking too much tissue from one leg. The options are discussed before surgery.
Is it ever too late to operate?
Chronic multi-ligament instability can still be reconstructed months or years later, though early repair options are lost and alignment correction may be needed first.
