Arthroscopy
- Early stage
sports injuries
Partial Knee Arthroplasty
- Early to mid-
stage
- steoarthritis
Total Knee Arthroplasty
- Late-stage
- steoarthritis
SLIDE 27
Total Knee Replacement
- Considered the Gold Standard for advanced OA of the knee
- Proven long term survivorship 90% out 15 years
- One of the most successful procedures in orthopedic medicine
Limitations
- Highly invasive
- Requires extensive rehabilitation
- May remove healthy cartilage and tissue
- Duke University study survey reports 88-92% of women and
men respectively decline hip and knee total arthroplasty when
- ffered*
SLIDE 28
Partial Knee Replacement
- Only targets diseased portion of the knee
- Smaller incision than total knee surgery1
Limitations
- Optimal implant positioning and alignment has historically been
challenging
- Requires extensive rehabilitation
- Less than 52,000 partial knee procedures in the U.S. in 2009,
compared to over 600,000 total knee procedures.2

- An overcorrection in valgus is
associated with an increased risk
- f degenerative changes in the
- pposite compartment**
- Severe under correction in varus is
associated with increased wear in the tibial component and recurrence of the deformity which was indicative of polyethylene wear**
