Diagnostic Arthroscopy…… If there is Lateral Joint Disease
not a candidate for partial knee replacement.

Narcotics
  The biggest challenge to outpatient surgery is pain control!
  Do not start out in the narcotic hole
  An occasional Vicoden or Darvocet is ok but be careful with
patients on pain medications

Consider…
Helps to have a pain doctor partner
  Pain Patches
  Triplicate analgesics
20
Antibiotics
  2 Gram Ancef 30 minutes prior
  2 Gram Ancef on discharge
  Consider 1 gram Vancomycin pre and post op
21
Home Health
  Home health and a cpm machine are good ideas with a pre-op
and night of surgery visit.
  Interesting enough it is difficult to get this service with nonMedicare patients and is not an absolute necessity
22
Equipment
 
 
 
 
23
Power tools
Larger Retractors
Cement Mixing
C-Arm
Procedure
  Do early in the day
  Takes approximately 90 minutes
  Inject local in the Posterior Compartment before cementing
implants
24
Recovery Room
 
 
 
 
25
Ice
Antibiotics
Pain meds (Oxycontin)
Crutches or Walker
Follow Up
  Home health is a plus but not necessary
  CPM helps stiffness and in most patients reduce pain and
improve function
  Explain to patient and family to try and stay ahead of the pain
  Follow up in clinic in 2-3 days
  Prefer out patient therapy
26
Results
  Crutches 2 weeks
  Most activities 4 weeks
  Athletics gradual return over about 12 weeks
27
Hurdles
  Making the diagnosis; although I think outpatient total knee
replacement is a viable cost
  Insurance Approval….
28
Comment
  Outpatient Joint Replacement is s viable cost effective
alternative to hospital based surgery
