Tendon transfer in foot drop: a systematic review
Stella Stevoska et al
Arch Orthop Trauma Surg. 2021 Sep 15

Introduction: Foot drop is a disorder that impairs walking and leads to tripping and falling. Tendon transfer (e.g., tibialis posterior tendon) is a typical secondary procedure in foot drop treatment. The purpose of this systematic review was to identify the most common tendon transfer techniques for treating foot drop and to analyze the reported functional outcomes. Furthermore, it was of interest if the type of surgical technique affects the functional outcome.

Methods: A PubMed and MEDLINE literature search was performed according to PRISMA guidelines. The search terms used were ("tendon transfer" OR "tendon transposition") AND ("foot drop" OR "peroneal neuropathies"). Any study published before January 2020 was considered for inclusion. No case reports or reviews were included. Common outcome measures (Stanmore score, AOFAS, FAAM, AFO use, patient satisfaction and active ankle dorsiflexion) were evaluated. The quality of the included studies was assessed using the Coleman Methodology Score.

Results: Of the 125 reviewed publications, 37 met the inclusion criteria. 42 cohorts were analyzed. The frequently reported tendon transfer technique was the tibialis posterior tendon transfer through the interosseus membrane. The most used fixation technique was tendon on tendon fixation; however in recent years, a tendon to bone fixation has gained popularity. There was an increase in Stanmore scores and AOFAS postoperatively and a decrease of AFO use postoperatively observed.

Conclusions: Due to various outcome measures and lack of preoperative assessment in the included studies, a meta-analysis of the pooled results was not possible. Nevertheless, the findings of this study show that tendon transfer increases mobility and self-independency leading to patient satisfaction. The choice of the surgical technique does not affect the outcome. A prospective collection of patient data and standardized outcome measures will be important to further analyze the efficacy of tendon transfer techniques.

Microsurgical Reconstruction for Reanimation of Foot Dorsiflexion in Children
Luke C E Allen , Grainne Bourke
Plast Reconstr Surg Glob Open. 2022 Mar 29;10(3)

Foot drop is a debilitating condition, which causes physical disability and psychological challenges associated with difficulties walking. We report the indications, novel technique, and successful outcomes of two children (three limbs) who underwent free functional gracilis muscle transfers coaptated to the common peroneal nerve to reanimate active foot dorsiflexion and correct foot drop secondary to loss of the anterior compartment.

Management strategies for the painless foot drop: a systematic review of the literature
S Waseem et al
Eur Spine J. 2023 Feb 26

Purpose: Foot drop can uncommonly be a painless presenting symptom of degenerative spinal disorders. This systematic review aimed to summarise the literature on the management and outcomes of patients with a painless foot drop.

Methods: We performed a systematic review of PubMed, EMBASE and Medline according to PRISMA guidelines. All studies published after 1980 in English referring to adult patients with a painless foot drop were included. Exclusion criteria included opinion based reports, review articles and articles in which foot drop was not caused by degenerative pathology of the thoracolumbar spine.

Results: Of 62 included patients, 30 (48.4%) were male with an average age of 48.7 years (range 27-84). The mean duration of symptoms was 69.0 days (1-700). 98.8% were managed operatively. 46 (74.2%) patients had symptomatic improvement, with 41 (66.1%) having a post-intervention MRC power grading of 3 or above. Patients with a pre-procedure MRC 0 had a higher median increase in MRC post-procedure than those with MRC > 0. Of two studies comparing painful and painless symptoms, painless foot drop patients were less likely to recover to MRC equal to or over 3 than those with painful symptoms OR 0.31 (95% CI 0.04-2.65).

Conclusion: This systematic review and meta-analysis demonstrates a role for surgery in facilitating the neurological recovery of patients with a painless foot drop. Large randomised controlled studies are required to characterise the role of operative intervention in these patients and compare outcomes between patients with painless and painful foot drop.
