Abstract

Grade II chronic tibialis posterior tendon dysfunction (PTTD) poses a reconstructive challenge to the orthopaedic surgeon. Aim of this retrospective study is to report the clinical and radiographical results of a case series of 63 patients (102 ft) affected by grade II PTTD who underwent tailored surgical treatment at 10-year mean follow-up.
MATERIALS AND METHODS:
Sixty-three patients (102 ft) were available for clinical and radiological evaluation and were retrospectively reviewed at a mean follow-up of 125.1 ± 14.9 months. Tibialis posterior (PTT) treatment was based on the pathological anatomy of the degenerated tendon. PTT repair was performed in 53 cases. Flexor digitorum longus transfer was performed in the remaining 49. Associated procedures were represented by medial displacement calcaneal osteotomy (MDCO) and lateral column lengthening (LCL) depending on the main clinical feature of the foot (hindfoot valgus and forefoot abduction, respectively). Patients' evaluation included AOFAS score and radiographic examination with measure of lateral talus-first metatarsal angle (LTFMA) and talo-navicular coverage angle (TNCA).
RESULTS WE OBSERVED FOUR FAILURES:
AOFAS hindfoot score was 89 ± 10 points at final follow-up. Eighty-six per cent of the patients declared to be satisfied or satisfied with minor reservations. An overall statistical significant decrease was observed in both LTFMA and TNCA values. A better TNCA correction was observed in case of associated LCL with respect to MDCO.
DISCUSSION:
Tailored PTT treatment associated with MDCO or LCL seems provide long-term pain relief and satisfactory function in the treatment of stage II posterior tibial tendon dysfunction.
