Defining the Issue:
Why discuss or consider Joint Resurfacing for the
Degenerative Knee
• 2 main scenarios where
this is relevant
1. Younger patients in

is not an attractive

2. “Middle Age” or
“Boomer” patients
wanting to maintain
high levels of function
Intro to Joint Resurfacing

• Variety of Etiologies
• Variety of Options
• Focus of this ICL is on
degenerative lesions
• Degenerative lesions MUCH more
common than focal defects
• Goal is to make sense of
evaluating and treating an array of
degenerative pathology while
incorporating some new treatment
paradigms
