Introduction/Purpose:
Use of hamstring tendon (gracilis and/or semitendinosus) autografts with limited morbidity and positive outcomes has been well reported in knee ligament reconstructions as well as in foot and ankle applications including chronic Achilles rupture or Achilles tendinosis augmentations. Advantages of hamstring autograft reconstruction when compared to alternative procedures such as local tendon transfers, synthetic grafts, or allografts are better healing and reduced morbidity within the foot and ankle. In this study, we examined the effect of Achilles tendon reconstruction using hamstring autografts on strength and functional outcomes. We hypothesized patients would experience positive outcomes following repair evidenced by significant outcome score improvements and limited ankle plantarflexor and knee flexor strength deficits when compared to patients’ contralateral side and dorsiflexion and extension strength respectively.
Methods:
Patients who underwent Achilles repair with a hamstring autograft by a fellowship-trained sports medicine and foot and ankle surgeon since 2011 were evaluated for inclusion. Patients younger than 18 or with history of contralateral lower extremity pathology were excluded. Thirty-one potential participants were identified. Patients, average age 38 ± 10.9, had strength testing at an average of 19 months post-operatively (range 15-28 months). Isokinetic testing was completed with a Biodex dynamometer under supervision of a physical therapist blinded to surgical side. Peak plantarflexion and dorsiflexion torque and toque at 30 degrees of plantarflexion were measured at speeds of 60 and 120 degrees/sec. Peak flexion and extension torque and torque at 30, 70, and 90 degrees of flexion were measured at speeds of 180 and 300 degrees/sec. Pre- and post-operative FAOS scores were reviewed retrospectively. Comparisons were completed using Student’s T-tests.
Results:
All patients except one have reported being very satisfied or satisfied with their surgery. The remaining patient reported being neither satisfied nor dissatisfied. One case reported pain at the harvest site. No additional surgeries were required and all patients would recommend their surgery to someone else. The only significant difference (p |
