CME OnDemand: 2022 AOFAS Annual Meeting-Functional outcomes of early weight bearing after modified Kidner procedure

Pdf Summary

The study aimed to evaluate the outcomes of patients who underwent the Kidner procedure with standard weight bearing (WB) compared to early WB. The Kidner procedure involves excision of an accessory navicular, a supernumerary bone within the posterior tibial tendon, and potentially relocating the tendon. Early WB is a newer trend in foot and ankle surgery. <br />The study included 34 patients with a mean final follow-up of 18 weeks. The control group (n=17) had standard WB at 6 weeks postoperative, while the study group (n=17) had early WB at 2 weeks postoperative. The groups were matched for similar age and surgical dates. <br /><br />The results showed that early WB did not increase complications compared to standard WB. The control group had four complications, including weakness in the posterior tibial tendon, stiffness and pain, and a deep vein thrombosis. The study group had only one complication of chronic flatfoot with posterior tibial tendonitis, which was treated with immobilization in a CAM boot and physical therapy. There were no cases of postoperative rupture or failure of the tendon repair in either group. <br /><br />The study suggests that early WB after the Kidner procedure may be protective against complications associated with prolonged immobilization, such as weakness, stiffness, and deep vein thrombosis. It supports the trend of early WB in foot and ankle surgery. <br /><br />It is important to note that this was a retrospective, comparative study with a relatively small sample size. Further research is necessary to validate these findings.
