Meniscal Function
Medial and lateral are NOT alike!!
Attachments AP slide on tibia
during ROM (LM) Tear patterns are
different
Meniscal Blood Supply
Arnoczky, et al.
Lateral Compartment
Young athlete Huge problem Synovitis Arthrosis

Medial Compartment
Young athlete Huge problem?
Not always Synovitis?
Not always Arthrosis?
Not always
No-Brainers – Do Not Repair
Complex tears Avascular flaps Avascular radial Degenerative soft tears Older patient (45 or 50+) Arthrosis in same compartment

NFL Case Example:28 y/o WO – ACL+ BHMMT
NFL Case Example
Weigh desire to repair vs. technical feasibility and potential for long-term success
Keep in mind that you didn’t hurt the player
Don’t feel guilty for PMM Failed MMR – more likely to
impact career of ANY athlete (Generally more arthrosis)

No-Brainers – Do Repair
Longitudinal peripheral tears Young patients Asso. Ligament surgery LM acute root avulsion w/ ACLT Really young kid – much more
aggressive – better healing, bigger problem long-term
Double longitudinal; big flaps; radial

Controversial Calls
Much higher failure rate Need good counselling w/ family Need good technique Imperative to avoid iatrogenic injury
(20 years of damage in 20 min) No matter what you do – future
surgery is likely (what type?) Really young + LMT = Push the limits
Dilemma
Most LM tears in athletes always lead to arthrosis - no matter what we do!
Repairs take the athlete out of sport for 3-4 months minimum
Arthrosis is often worse after failed MR than after PM
Instrumentation & implants are not benign - risk of iatrogenic chondral injury

Learn to be versatile with your MR techniques
Be aggressive with LMR in young pts Don’t feel guilty if you need to do a
partial mensicectomy Involve the patient in the decision Do no harm w/ your techniques!
