Diagnosis: posterior tibial tendon dysfunction.
Operations performed:
- Secondary reconstruction of the left posterior tibial tendon.
- Flexor digitorum longus tendon transfter.
- Intraoperative fluoroscopy.
The original incision was extended to fully expose the posterior tibial tendon. The posterior tibial tendon sheath as opened and an extensive straw-colored fluid was drained from the tendon sheath. There were obvious signs of tendinosis. The anterior portion of the tendon was severely thickened and tendinotic, and this was excised from its attachment into the navicular. The more plantar portion of the tendon appeared to be more intact with healthier looking fibers, but about 60% of the tendon width had to be resected. The remaining tendon was tubularized and prepared for a flexor digitorum longus tendon transfer. The repair was good with no signs of weakness of the repair.
Postoperative plan:
Non-weightbearning for full 6 weeks, in fiberglass cast. At 6 weeks, switch to a CamWalker book and begin PT.
