Tendon Transfer versus Allograft Reconstruction in Progressive Collapsing Foot Deformity

Area of Science:

• Orthopedic surgery
• Foot and ankle reconstruction
• Biomaterials in surgery

Background:

• The posterior tibial tendon (PTT) is crucial for maintaining the medial longitudinal arch of the foot.
• Posterior tibial tendon dysfunction (PTFD) leads to arch collapse and foot deformities.
• Current surgical reconstructions aim to restore arch height and foot function.

Purpose of the Study:

• To evaluate the rising trend of allograft reconstruction for the posterior tibial tendon (PTT).
• To compare allograft reconstruction with the established flexor digitorum longus (FDL) tendon transfer.
• To highlight the evolving surgical strategies for posterior tibial tendon dysfunction (PTFD).

Main Methods:

• Review of current literature on PTT reconstruction techniques.
• Analysis of trends in the adoption of allograft versus autograft (FDL) procedures.
• Discussion of the biomechanical principles and outcomes associated with each method.

Main Results:

• The flexor digitorum longus (FDL) transfer has been the traditional gold standard for PTT reconstruction.
• Allograft reconstruction of the PTT is demonstrating increasing popularity in recent surgical practice.
• This shift suggests a potential re-evaluation of reconstruction options for PTFD.

Conclusions:

• Allograft reconstruction represents a growing alternative for PTT reconstruction.
• The choice between allograft and FDL transfer depends on various surgical and patient factors.
• Further research is warranted to fully elucidate the long-term efficacy of allograft PTT reconstruction.
