Actual Enrollment : 25 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)

Arm Intervention/treatment
No Intervention: 1
Patient will receive post-surgical standard of care treatment with standard Physical therapy and NSAIDs.
Experimental: 2
Patients will be treated with the Standard of Care physical therapy and NSAIDs as well as a Knee Extension Dynasplint that includes tension chambers.
Device: Knee Extension Dynasplint
Dynamic Splinting utilizes the protocols of Low-Load, Prolonged-Duration Stretch (LLPS) with calibrated, adjustable tension to increase the Total End Range Time (TERT) to reduce contracture. The Knee Extension Dynasplint for the Experimental group will have tension chambers delivering therapeutic treatment from the device.

Primary Outcome Measures :
  1. Change in Maximal Acitive Range of Mothion in knee extension [ Time Frame: 9 weeks ]
