Abstract

The anterior cruciate ligament (ACL) of the knee is an intra‐articular ligament that fails to heal after primary repair. The medial collateral ligament (MCL) of the knee is an extra‐articular ligament that heals uneventfully in the majority of cases. Why these two ligaments have such different responses to injury remains unclear. In this article, we address two hypotheses: first, that the histologic response to injury is different in intra‐articular and extra‐articular ligaments, and second, that the response of the intra‐articular ligaments can be altered by placing a collagen–platelet‐rich plasma (collagen‐PRP) hydrogel in the wound site. Wounds were created in extra‐articular ligaments (MCL and/or patellar ligament) and an intra‐articular ligament (ACL) in canine knees, and the histologic response to injury evaluated at 3 days (n = 3), 7 days (n = 4), 3 weeks (n = 5), and 6 weeks (n = 5). In the 3‐week (n = 5) and 6‐week (n = 5) animals, bilateral central wounds were made in the ACLs and the wounds in one knee of each animal treated with a collagen‐PRP hydrogel while the contralateral side was untreated. Extra‐articular ligament wounds had greater filling of the wound site and increased presence in the wound site of fibrinogen, fibronectin, PDGF‐A, TGF‐β1, FGF‐2, and von Willebrand's factor when compared to intra‐articular ligament wounds. Treatment of the intra‐articular wound with a collagen‐PRP hydrogel resulted in increased filling of the wound site with repair tissue that had similar profiles of growth factor and protein expression to the extra‐articular ligament wounds. The use of a collagen‐PRP scaffold can ameliorate histologic differences noted between healing extra‐articular ligamentous wounds and nonhealing intra‐articular ligamentous wounds. This study supports the hypothesis that premature scaffold failure may play a key role in the normally expected failure of the ACL to heal after injury. Published by Wiley Periodicals, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
