Abstract
The purpose of this study was to evaluate serial changes in magnetic resonance imaging (MRI) and clinical outcomes after reconstruction of achilles tendon rerupture after primary repair in athletes with the use of the reversed free tendon flap made from the gastrocnemius muscle a minimum 2 years postoperatively.
From October 2010 to September 2020, 46 patients underwent achilles tendon reconstruction using the reversed free tendon flap made from the gastrocnemius muscle and 20 athlete patients (11 women and 9 men) with average age of 29.5 at time of surgery who were followed up more than 2 years were evaluated by MRI (1.5T-proton density-weighted images) at 3, 6 and 12 months after surgery.
The average time from the primary surgery was 28 weeks (range: 13 to 51 weeks).
The MRI evaluation focused on single intensity of the achilles tendon by sagittal images. To quantitatively determine normalized single intensity of achilles tendon, the single/noise quotient (SNQ) was calculated. Circular 4.0mm (12.6mm2) regions of interest were evaluated and each measurement was performed three times and the averages was recorded.
Clinical examination was performed on the same day when the MRI examination was performed, including subjective functional examinations (The Achilles tendon Total Rupture Score (ATRS) ).
The mean SNQ value of the reconstructed tendon became well stabilized by 1 year. After surgery, no patient had a significant functional deficit and all patients had a satisfactory recovery of function and were able to return to sports.There were no postoperative infections, skin losses, or re-ruptures. The mean ATRS score increased from 41.25 ± 13.21 preoperatively to 95.05 ± 4.11 at final follow-up (P < 0.05).
Reconstruction with the use of the Reversed free tendon flap made from the gastrocnemius muscle is a reasonable option for treatment of Achilles tendon rerupture after primary repair.
