straight

11
Q

Needle shape used for placing suture under the lateral fabella for lateral stabilization of an ACL rupture?

A

J needle

12
Q

What’s the relationship b/w suture size and tensile strength?

A

larger size= inc TS

13
Q

If there’s pathology present in a tissue, would absorbable or non-absorbable suture be more appropriate?

A

non-absorbable

[slower healing tissue, want a longer lasting suture]

A

dec tissue drag,

inc pliability

19
