The primary issue was damage to the syndesmotic ligament which is within the region beow defined as Interosseous membrane.
- The secondary issue was hairline fracture of the small bone (
fibula).
- No surgery was required specific to the hairline fracture.
The old school repair included putting screws throught he small bone (
fibula) to hold it together with large bone (
tibia) while the ligament healed.
- Then a 2nd surgery was required to remove the screws.
- The 2 bones must have some amount of indepentent movement; therefore, they can't be permanantly screwed together.
The newer tightrope surgery uses a rope like material to hold the 2 bones together while the ligament heals.
- The primary advantage is that a 2nd surgery is not required. The "rope" can remain forever.
The average recovery time is 2 months.
- Tua Tagovailoa had the tightrope surgurical procedure and returned to play in 28 days.
The minimum recovery time for ACL surgery is 9 months.
- i.e. Pollard's injury has a far shorter recovery time than an ACL tear like Gallup had.
