PURPOSE: The objective of this study was to determine the responses of normal meniscus to collagenase activity. It was hypothesized that meniscal explants exposed to collagenase would significantly increase release of pro-inflammatory cytokines and degradative enzymes, in a dose-dependent manner, compared to control.

OBJECTIVE: To determine a relationship between morphometric measurements (MM) and meniscal dimensions (MD) in the dog.
STUDY DESIGN: Cadaveric study.
ANIMALS: Eighteen mixed-breed canine cadavers (22.35 ± 4.06 kg); 36 each of medial and lateral menisci.
The aim of this in-vitro study was to investigate the response of articular cartilage to frictional load when sliding against a metal implant, and identify potential mechanisms of damage to articular cartilage in a metal-on-cartilage pairing.

Articular cartilage damage and osteoarthritis (OA) are common orthopedic diseases in both humans and dogs. Once damaged, the articular cartilage seldom undergoes spontaneous repair because of its avascular, aneural, and alymphatic state, and the damage progresses to a chronic and painful situation. Dogs have distinctive characteristics compared to other laboratory animal species in that they share an OA pathology with humans.
