One-stage reconstruction of soft tissue and Achilles tendon defects using a composite free anterolateral thigh flap with vascularized fascia lata: clinical experience and functional assessment

The combined loss of the Achilles tendon with overlying soft tissue is a reconstructive challenge. To achieve acceptable rehabilitation, such patients need skin coverage including functional repair of the Achilles tendon. This article presents four such patients who were treated successfully by means of an anterolateral thigh (ALT) composite flap with vascularized fascia lata. The size of the ALT flaps ranged from 10 to 16 cm in length and 6 to 9 cm in width. All flaps included vascularized fascia lata, which was rolled to serve as vascularized tendon graft (range 8 x 6 cm to 10 x 8 cm) for reconstruction of the Achilles tendon defect. Flap success rate was 100%. All patients could walk and climb stairs without support; however, mild difficulty when running was reported. Functional outcome of the recipient ankle and donor thigh morbidity were investigated by using a kinetic dynamometer comparing reconstructed sides with the healthy contralateral limbs. This assessment was performed in two patients at 2 years postoperatively. In the reconstructed ankles, isokinetic concentric measurements of dorsiflexion and plantar flexion showed a deficit of 30% and 40%, respectively. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed a 10% to 25% deficit. However, there were no difficulties in daily ambulating. In summary, the free composite ALT flap with vascularized fascia lata provides an alternative option for Achilles tendon reconstruction in complex defects.     

Reconstruction of Achilles tendon using vascularised fascia lata with free lateral thigh flap

A case of Achilles tendon reconstruction using free vascularised fascia lata joined to a lateral thigh flap is reported. This is a simple one-stage reconstruction and a sufficiently strong tendon can be obtained.     

Reconstruction of the Achilles tendon and overlying soft tissue using antero-lateral thigh free flap.

Reconstruction of combined loss of the Achilles tendon and overlying soft tissue was performed using an antero-lateral thigh free flap in three patients. The cutaneous portion is used to cover the open wound, and a piece of fascia lata is utilised to replace the missing segment of the Achilles tendon. The skin defect ranged from 5 x 2.5 to 7 x 5 cm, and the tendon loss measured from 3.5 to 5.5 cm in length. All of the patients showed satisfactory functional results with a follow-up period from 3 to 9 months. The advantages of the procedure are that: it is a single-staged operation; it promotes rapid healing of the tendo Achilles since the tendon substitute is well vascularised; it is adaptable to a wide range of defect sizes and shapes; it can be performed in the supine position without the need for postural change; and it can restore good contour and causes minimal morbidity at the donor site.     

Reconstruction of soft tissue defects including the Achilles tendon with free neurovascular tensor fascia lata flap and fascia lata. Case report

The combined loss of the Achilles tendon and the overlying soft tissue in the young ambulant patient with expectations of a normal life is a challenge. These patients need not only skin coverage but also dynamic, functioning repair. Two cases of major defects after tumour resection are presented. In each case the tendon was reconstructed using the remaining gastrocnemius aponeurosis reinforced with fascia lata. This was covered by a free tensor fascia lata (TFL) flap. In one of the cases the flap was transferred as a neurovascular free flap.     

Reconstruction of combined defects of the Achilles tendon and the overlying soft tissue with a fascia lata graft and a free fasciocutaneous lateral arm flap

A new approach to reconstruction of the Achilles tendon and overlying soft tissue is presented. A fascia lata graft is used to reconstruct the tendon and is enwrapped by the fascia that is included in a fasciocutaneous lateral arm flap. Five patients were treated with this technique; three of them after surgical Achilles tendon repair, rerupture, and consecutive infection, one after a full-thickness burn with loss of the tendon and one with a history of ochronosis and necrosis of the whole tendon and overlying soft tissue. There were no anastomotic complications and all flaps healed primarily. Functional evaluation with the Cybex II dynamometer was done at least 49 months after reconstruction. A good functional and cosmetic result was obtained in all patients and donor site morbidity was acceptable. These results are well within the results of other surgical treatment options reported in the literature.     

One-stage reconstruction of large midline abdominal wall defects using a composite free anterolateral thigh flap with vascularized fascia lata

OBJECTIVE: Large midline abdominal wall defects are continuously a challenge for reconstructive surgeons. Adequate skin coverage and fascia repair of the abdominal wall is necessary for achieving acceptable results. The purpose of this paper is to present a new approach to abdominal wall reconstruction using a free vascularized composite anterolateral thigh (ALT) flap with fascia lata. METHODS: Seven patients with large full-thickness abdominal wall defects were successfully reconstructed by means of a composite ALT flap combined with vascularized fascia lata. The size of the skin islands ranged from 20 to 32 cm in length and 10 to 22 cm in width, and the vascularized fascia lata sheath measured 14 to 28 cm and 8 to 18 cm, respectively. Functional outcome of the abdominal wall strength and donor thigh morbidity were investigated by using a Cybex kinetic dynamometer. RESULTS: All flaps survived. No postoperative ventral hernia occurred except for one mild inguinal incision hernia. Subjectively there were no significant donor site problems. Objective assessment was performed in 4 patients 2 years postoperatively. In the reconstructed abdomen, isokinetic concentric and eccentric measurements of extension/flexion ratios of the abdominal wall strength showed no apparent decrease compared with other references. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed an averaged deficit of 30% as compared with the contralateral legs. However, no difficulties in daily ambulating were reported by the patients. CONCLUSION: The free composite ALT myocutaneous flap with vascularized fascia lata provides an alternative option for a stable repair in complex abdominal wall defects.

Single stage functional reconstruction of both peroneal tendons and overlying skin with an anterolateral thigh flap and vascularized fascia lata: A case report

Reconstruction of complex soft tissue defects in the distal lower leg remains challenging, since anatomical constraints limit the local options available in this area. In this report, we present a case of single stage functional reconstruction of both peroneal tendons and overlying skin with an anterolateral thigh flap and vascularized fascia lata. A 55‐year‐old patient underwent wide excision of a synovial sarcoma in the distal lower leg, which resulted in a complex defect including the peroneus longus and brevis tendons (10 cm), and the overlying skin (14 × 8 cm). Functional reconstruction was achieved in a single stage with a composite anterolateral thigh flap with vascularized fascia lata of similar dimensions to those of the defect. The fascia lata component of the flap was longitudinally split in two segments. Each of them was rolled up, and that way, two separate vascularized neotendons were created. The neotendons bridged the gap of peroneal tendons, whereas the skin paddle of the flap provided stable soft tissue coverage to the reconstructed tendons. Flap pedicle was anastomosed to the anterior tibial vessels. Early and late postoperative periods were uneventful. Follow up at 1 year postoperatively showed excellent neotendon incorporation, as well as a very good functional and aesthetic outcome. The use of the method described may be a useful alternative in single stage functional reconstruction of composite defects comprising two or even more tendons and the overlying skin.

Quadriceps tendon reconstruction using a fascia lata included in a reverse‐flow anterolateral thigh flap

Quadriceps tendon re‐rupture after surgical repair is an overall estimated 2% complication. We report a case of reconstruction in a large tendon and soft tissue defect using a reverse‐flow anterolateral thigh (ALT) perforator flap including fascia lata in a 75‐year‐old man presented with septic necrosis of a reconstructed quadriceps tendon. A reverse‐flow ALT flap was transferred to the knee defect; the fascia lata was sutured to the residual tendon. Post‐operative flap congestion and infection were successfully treated with debridement and conservative treatment. One year after surgery, the patient was able to fully and actively extend the knee, with an acceptable aesthetic appearance. The reverse‐flow anterolateral thigh flap including fascia lata may be a good option for coverage of soft‐tissue defects around the knee and contemporary quadriceps tendon reconstruction, particularly in case of septic tendon necrosis, where the use of non‐vascularised tissues is contraindicated.
