8. Multiple Ligament Knee Injuries
⢠Non-operative vs. operative treatment
⢠Early vs. delayed surgery
⢠Early vs. delayed rehabilitation
Controversies for Treatment:
9. Multiple Ligament Knee Injuries
⢠Multiple studies consistently demonstrate
operative treatment is superior to non-operative
treatment
â More likely to return to work and sports
â Higher patient-reported outcomes
â Lower rates of PTOA
Non-Operative vs Operative Treatment:
10. Timing of Surgery
10
⢠Some advocate for early surgical intervention within 3
to 6 weeks:
â Tissue planes more easily identified
â Tissue quality sufficient to hold sutures for repair
â Less retraction of tissues, such as tendon
⢠Others advocate for delayed surgery to decrease
surgical risks:
â Compartment syndrome due to extravasation of fluid during
surgery
â Post-operative arthrofibrosis
11. Timing of Surgery
11
â Early (0-3 weeks)
ď¤Hamstring/ITB Avulsion
ď¤Nerve injury?
ď¤Locked knee, bucket handle, etc
â Delayed (3+ weeks)
ď¤Reconstruction
ď¤Fracture (+/- ORIF)
ď¤Prefer to get full motion back first
12. A Multicenter Randomized Clinical is
Needed to Provide Level 1 Evidence
for the Timing of Surgery & Post-
operative Rehabilitation for Treatment
of MLKIs
