Tissue Specific Considerations

Tissue Involved	Rehabilitation Modifications
ACL	No modifications to rehabilitation
PCL	Protect posterior translation of the femur for 6 weeks - Anterior tibial glide with knee flexion - Avoid gravity causing posterior glide
	Protected Hamstrings Contractions: - Weeks 0 to 8 – No active hamstring contractions  Passive flexion ROM with support to the posterior tibia x 6 wks - Weeks 8 to 12 – Active hamstrings contractions without external resistance  Based on absence of active posterior drawer with hamstring activation  Active hamstring exercises (heel slides, prone knee flexion, WB flexion)  Gentle hamstring stretching - Weeks 12+ - Resisted hamstring contractions allowed  Based on absence of active posterior drawer with hamstring activation
PLC	Extension ROM limited to 0o (no hyperextension)
	Protect posterior translation of the femur for 6 weeks - Anterior tibial glide with knee flexion - Avoid gravity causing posterior glide
	Avoid excessive varus forces on knee joint
	Hamstring restrictions same as PCL
MCL	ROM exercises with foot internally rotated
	Avoid excessive valgus forces on knee joint
Meniscus Body Repair	Brace locked in extension for 4 weeks for ambulation, WBAT
	Avoid unilateral WB flexion (any range) & bilateral WB flexion beyond 30o for 4 wks
	NWB flexion ROM to 90o for 4 weeks
Meniscus Root Repair	NWB x 4 weeks
	Protected Hamstrings Contractions: - Weeks 0 to 6 – No active hamstring contractions  Passive flexion ROM with support to the posterior tibia x 6 wks - Weeks 6 to 12 – Active hamstrings contractions without external resistance  Based on absence of posterior pain at the repair site with hamstring activation   Active hamstring exercises (heel slides, prone knee flexion, WB flexion) - Weeks 12+ - Resisted hamstring contractions allowed  Based on absence of posterior pain at the repair site with hamstring activation
