Studies

STRAVIX Cryopreserved Umbilical Tissue in tendon repair16, 17


Ruptured Achilles tendons16

Study overview

  • Retrospective, single-center analysis of four patients (average age 59) with acute partial or complete Achilles tendon injuries surgically treated with STRAVIX Tissue
  • Four patients (average age 60) from the same institution with similar degrees of Achilles tendon rupture and similar surgical procedures without treatment with STRAVIX Tissue were used as a control group for comparison
  • STRAVIX Tissue and control patient histories include diabetes, hypertension, cancer, hypercholesterolemia, osteoporosis, rheumatoid arthritis and smoking

Procedure

  • End-to-end repair, autograft repair or cadaveric tendon graft for structural repair of rupture
  • Repair augmented with STRAVIX Tissue sutured over the tendon ends with absorbable sutures (not performed on control patients)
  • Non-weight bearing postoperative for 4-6 weeks

Results

When Achilles tendon repair was augmented with STRAVIX Tissue, patients returned to pre-injury activities sooner

Time to return to normal shoe gear (mean): 6.25 weeks for STRAVIX Tissue versus 11.5 weeks for control

All STRAVIX Tissue-treated patients:

  • Maintained durable skin closure
  • Returned to pre-injury activity levels without loss of function


Ruptured peroneus brevis, Achilles and posterior tibial tendons17

Study overview

  • Retrospective, single-center study on STRAVIX Tissue as an adjunct surgical wrap in the repair of ruptured tendons in five patients (average age 41)
  • Ruptured tendons included two peroneus brevis tendons, two Achilles tendons and one posterior tibial tendon
  • All patients had failed six months of conservative therapy

Procedure

  • End-to-end structural repair of the tendon rupture
  • STRAVIX Tissue wrapped circumferentially around the tendon and secured with absorbable sutures
  • Second piece of STRAVIX Tissue laid along incision site before skin closure
  • Non-weight bearing postoperative for three weeks

Results

Time to return to normal shoe gear (mean): 5.6 weeks
