Objective In contrast to posterior tibial tendon lesions, dislocations of the posterior tibial tendon are thought to be ‘extremely rare’. Diagnostic criteria for this condition have not yet been established.

Methods A systematic literature review revealed 61 published cases with posterior tibial tendon dislocation in 36 reports, including eight (12 patients) in French and five (7 patients) in German. We add one more case, which was complicated by a longitudinal tibial tendon tear and a lateral talar dome osteochondral lesion. Fifty-nine cases were descriptively analysed regarding initial injury, subjective symptoms, clinical presentation and findings on different imaging modalities. Treatment and outcome were additionally evaluated.

Results 58.5% of the initial injuries were induced by sport. Initially most cases were misdiagnosed (53.1%). 35.6% of the patients felt a recurrent snapping phenomenon at the medial ankle. Physical examination exhibited a cord-like structure over the medial malleolus in 58.6%, and a posterior tibial tendon (sub)luxation could be provocated in 54.2%. MRI, ultrasound and plain radiography (medial malleolar chip fracture) detected specific findings in 75.0%, 66.7% and 14.7%, respectively. Surgery was done in 83.1% of the patients using varying techniques. The authors judged the treatment result as excellent or asymptomatic in 80%, as good in 12% and as fair or moderate in 8% of the patients.

Conclusions Posterior tibial tendon dislocation occurs more frequently than was previously thought. Misdiagnosis can be avoided, if the surgeon is aware of the condition and combines findings from history, physical investigation and imaging modalities.

Posterior Tibial Tendon Dislocation: a Case Report
Stefania Zannoni et al
JFAS; September 21, 2021

Isolated posterior tibial tendon dislocation is a rare condition. Diagnosis can be challenging, especially in the acute clinical setting. Predisposing factors include shallow posterior tibial tendon groove and tear of the flexor retinaculum. We report the case of traumatic subluxation of the posterior tibial tendon, illustrating imaging findings and surgical technique. Posterior tibial tendon dislocation was detected using dynamic ultrasound, while magnetic resonance was essential for a comprehensive evaluation that included underlying predisposing anatomic abnormalities and associated pathologic conditions. Conservative treatment is often unsuccessful thus surgical approach was needed. Under ampliscopic guidance, a bone tunnel was created behind the retromalleolar groove. The PTT was located into the new groove and the retinaculum was re-attached and tightened by anchors and absorbable sutures at the anterior margin of the sulcus. At 12-months follow-up the patient did not complain any residual pain and he was able to perform normal daily activities without any limitations and with no further tendon dislocations.
