Adipose cellular injection in the treatment of an intrasubstance Achilles tendon defect: a case report.

Our patient presented with a 1-year history of right sided Achilles tendon pain and weakness due to partial intrasubstance tear. The injury was refractory to conservative treatment, leading to a trial injection of microfragmented adipose tissue. Progressive healing and improved function were documented on physical exam and sonographically at subsequent follow-up appointments.
