Repair of Achilles tendon rupture using autologous semitendinosus graft in a kidney transplant recipient

Biologically Enhanced Hamstring Tendon Transfer for Treatment of Acute Rupture of Posterior Tibialis Tendon in an Athlete: Case Report

We report the case of a 32-year-old basketball player who presented with an acute flatfoot deformity after performing a unipodal power jump. Rupture of the posterior tibial tendon within the foot was diagnosed and then treated by hamstring tendon transfer combined with application of autologous biologic preparations. The functional outcome at 18 months was good. To our knowledge, this is the first reported case of posterior tibial tendon rupture treated by hamstring tendon transfer.

Hamstring Autograft for Foot and Ankle Applications

BACKGROUND

Hamstring tendon autografts may be used for foot and ankle surgeries, although reports on their effectiveness and morbidity in the foot and ankle literature are limited. We studied a cohort of patients who underwent hamstring harvest for foot and ankle applications, hypothesizing that morbidity to the knee would be limited.

METHODS

We studied a cohort of patients who underwent hamstring autograft for foot or ankle applications by a fellowship-trained sports and foot and ankle surgeon since 2011. Thirty-seven patients underwent isokinetic strength testing using a dynamometer an average of 38 months postoperatively. The average patient age was 45 ± 16 (range, 18-78) years, and 54% were women. Peak flexion and extension torque as well as flexion and extension torque at 30, 70, and 90 degrees of flexion were collected at 2 different testing speeds, 180 and 300 degrees/s. t tests were used for all comparisons.

RESULTS

At follow-up, 32 patients (86%) reported no pain at the harvest site; the remaining 5 patients reported mild to moderate symptoms. No patients were dissatisfied, and all would recommend the surgery to someone else. Flexion strength at higher degrees of flexion was significantly lower compared with extension strength as well as compared with flexion strength at lower degrees of flexion, when testing was performed at lower speed ( P < 0.05).

CONCLUSIONS

When used for foot and ankle surgery, hamstring autografts resulted in high patient satisfaction with minimal donor site morbidity. While knee flexion strength was decreased at higher degrees of flexion, this finding did not appear to be clinically significant.

Reconstruction of chronic Achilles tendon rupture using the semitendinosus tendon: a case report

Achilles tendon rupture is a common trauma requiring surgical management. For chronic Achilles tendon rupture in particular, reconstructive surgery is desirable and several methods have been described. Here we present a case of chronic Achilles tendon rupture reconstructed using the semitendinosus tendon because of the difficulty in pulling down the proximal stump to reach the distal stump and due to an insufficient margin for hooking a suture to the distal stump. Postoperatively, the patient had a fully functional tendon and resumed his normal activities of daily living. Using this surgical technique, we expect favorable outcomes in cases of Achilles tendon rupture.
