Case Study: Intercollegiate Football Running Back with
Traumatic Knee Dislocation and Multiple Ligament Injury
Ron Courson, ATC, PT, NRAEMT, CSCS
Senior Associate Athletic Director – Sports Medicine

Athens, GA
Objectives
• Review mechanism of injury and
on-field clinical findings with knee dislocation
• Discuss emergency care
considerations
• Review role of diagnostic testing
with knee dislocation
• Review surgical considerations with multiple-ligament injury
• Discuss coordination of pre- and
post-op rehabilitation and use of
novel techniques within rehabilitation
Traumatic Knee Dislocations
• Traumatic knee dislocations
leading to multiple ligament injury are relatively uncommon
but not rare injuries
• These injuries demand prompt
and appropriate attention
• Knee dislocations represent one of the few true orthopedic
emergencies due to potential
limb-threatening nature
• Post-operative management must be carefully coordinated
with early ROM to restore
functional motion without compromising knee stability
Mechanism of Injury
Initial Exam
• NV check (serial exams)
• Stabilize extremity
• Thorough exam
• Appropriate supporting studies
Work up• Xrays
• MRI
• CT scan

Selective Arteriography (CTA)
Serial Physical Exam (6, 24, 48hrs)
Equal pulses
• ABI <0.9
• Expanding hematoma
• Hx dysvascular foot
• 90% positive predictive value
• 100% negative predictive value
– Stannard 2004
Surgical Plan
• Multiple surgeons
• Multiple injuries
• Multiple scenarios
• Multiple options
Plan
• Scope, I & D
• Open Lateral repair +/-reconstrxn
• Scope repair PCL, MMT’s
Case Study• Post-Operative Diagnosis:
– PCL tear
– Posterior lateral corner tear
– LCL tear
– Biceps femoris tear
– Medial mensicus tear both anterior and
posterior horns
• Procedure:
– Arthroscopically assisted PCL repair
– Medial meniscus repairs anterior and
posterior with debridement
– Open LCL, posterolateral corner and biceps femoris repairs with peronealnerve neurolysis and allograft figure-of-
eight posterolateral corner reconstruction

Bony Preparation Fibular-Based PLC Recon
Arthroscopic
Portion
• Proximal PCL Repair
• Ant and Post horn MMR
Immediate Postop
• “Controlled Arthrofibrosis”
• Hinged knee brace locked in
full extension for 1st 2 wks
Rehab Program Considerations• Problem-solving approach
– physiologic healing constraints
– pain
– swelling
– ROM restrictions
– muscle atrophy
– decreased
balance/proprioception
– DVT/PE prophylaxis
– deconditioning/weight loss
Rehab Program Considerations
• Is rehabilitation program:
– evidence based ?
– communicated with all parties
?
– challenging/fun ?
• Does rehabilitation:
– avoid redundancy ?
– vary rehab activities ?
– utilize all available resources ?
• Is progression based upon:
– physiologic healing
constraints ?
– achieving rehab goals ?
– MD direction ?

Acute Rehab Phase
• NWB x 6 weeks
• Dynamic PCL brace
• locked in full extension x 2 weeks
• Pain/Swelling control
• DVT/PE prophylaxis:
• Xarelto
• VenoPro
• ROM:
• started prone PROM at 2 weeks
• started CPM with posterior strap
on proximal tibia to prevent sag
• opened brace at 2 weeks with 0-90 degree motion restrictions
Acute Rehab Phase• PRE:
• quad sets/SLR isometrics
• active assisted with ESC
• biofeedback
• no isolated active hamstring PRE x 4 months
Intermediate Rehab Phase
• 6 weeks post-op
– deep-water running in pool
– KAATSU blood flow restriction therapy
• 7 weeks post-op
– Flexinator (knee ROM)

– full weight-bearing
Intermediate Rehab Phase
• 8 weeks post-op:
– CKC exercise progression
• squat variations
• step-up variations
• leg press (single and
double)
• lunges
– Gait training
• hurdle stepping
– forward, back, side
– Basic balance/proprioception
Intermediate Rehab Phase
• 10 weeks postop:
– Eccentron eccentric quadriceps training with emphasis on both strength development and force control
Intermediate Rehab Phase
• 12 weeks post-op:
– OKC knee extensions
– running on underwater treadmill
