Final answer:
Jason likely suffered from myorrhexis, which is the rupture of a muscle, as Dr. Borra had to perform a myorrhaphy, a surgical procedure to repair a torn muscle.
Step-by-step explanation:
Dr. Borra performed a myorrhaphy, which is a surgical procedure to suture or repair a torn muscle. Based on this information, Jason is most likely suffering from a muscle disorder known as myorrhexis. Myorrhexis is the term used for a torn or ruptured muscle, which aligns with the need for myorrhaphy. Muscle disorders like adhesion, myolysis, and atrophy indicate different conditions: adhesion refers to abnormal fibrous tissue preventing normal muscle movement, myolysis is the breakdown or dissolution of muscle tissue, and atrophy is the wasting away or decrease in size of muscle tissue due to lack of use or disease.
