69
What are the three stages of progression of RA?
Progresses in three stages:
1. Swelling of the lining causes warmth, pain
stiffness, and redness around the joint
2. Rapid division and growth of cells or pannus
which causes synovium to thicken
3. Inflamed cells release enzymes that may digest
bone and cartilage often causing deformity,
increased pain and loss of joint mobility

working

and custom ‘jigs’ are made for a more precise fit
• Unilateral knee/partial knee
– Need to have ligaments intact
• Protocols vary by institution some are more
aggressive than others

to rehab (typically a SAR)
