Knee problems

[Sally & Frank Shanley,and Megan]

Megan has a problem and we thought maybe others may have insight.　 She is four, very active and yesterday while playing ball started limping, holding up her left rear leg.　 We took her to the vet who said she "probably" had a cruciate ligament rupture that requires surgery at the cost of about 1500- yikes!　 Has anyone had any experience with this type of injury?

[Linda, Webber and Seda]

Good wishes for a successful recovery.  Bless her little heart.
