Laxity vs instabilityLaxity vs instability

Laxity — clinical sign of the amount of Laxity — clinical sign of the amount of “give” within a joint; identified by stress “give” within a joint; identified by stress testingtesting

Instability — joint’s inability to function Instability — joint’s inability to function under the stresses of function activityunder the stresses of function activity
