Technical tips: Reconstruction of deep and superficial deltoid ligaments by peroneus longus tendon in stage 4 posterior tibial tendon dysfunction

The deltoid ligament is composed of the superficial and deep layers. Disruption of the deltoid ligament can occur in rotational ankle fracture, chronic ankle instability, or stage 4 posterior tibial tendon dysfunction. Correcting valgus tilt at the time of flatfoot reconstruction in case of stage 4 posterior tibial tendon dysfunction may prevent future collapse and the need for ankle arthrodesis or possibly ankle arthroplasty. We describe a technique of reconstruction of both the superficial and deep deltoid ligaments by peroneus longus tendon.

Reconstruction of the lateral ankle ligaments using a split peroneus brevis tendon graft

Thirty-one consecutive ankles in 30 patients with chronic lateral ankle instability were reconstructed using a split peroneus brevis tendon graft. All patients had pain and instability despite adequate treatment and a rehabilitation program. Six patients had clinical and radiographic evidence of associated subtalar laxity. Four patients (four ankles) had prior Brostrom ligament reconstructions. The average time from the initial injury or treatment to surgery was 23 months. At a mean follow-up of 44 months (range, 24-64 months), the functional results included excellent in 20 ankles, good in 9, fair in 1, and poor in 1. Ankle stability, which did not deteriorate with time, was achieved in 30 of 31 ankles. This procedure is simple, safe, and reliable with a 94% good to excellent clinical result and 97% mechanical stability. It is an excellent reconstruction choice for those individuals with high demand ankles, with a longstanding ankle instability with or without subtalar instability, and for failed primary reconstruction.

Stabilization of medial longitudinal foot arch by peroneus longus transfer

The mechanical integrity of the medial longitudinal arch depends on the dynamic support of muscles and the static support of ligaments. Although the posterior tibial tendon is the main dynamic stabilizer of the arch, the static structures provide the most support especially while the person is standing. After rupture of the posterior tibial tendon, the spring ligament may be compromised under increased stress and leads to talar derotation and peritalar subluxation. Surgical repair of the spring ligament has become an important adjunct to treating posterior tibial tendon abnormalities. A technique of peroneus longus transfer to augment the static stabilizers of the medial column is described in this article.

Anatomical reconstruction of the lateral ligaments using Gracillis tendon in chronic ankle instability; a new technique

Background

Many surgical technique have been described to assess the outcome of anatomical reconstruction of the lateral ligaments using Gracillis tendon. This technique aims to restore the stability of the ankle by reconstruction of the talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) using the Gracillis tendon.

Methods

From January 2004 to February 2008; inclusive, 16 patients; 11 male and 5 female, underwent an anatomic reconstruction of the lateral ankle ligament for chronic ankle instability. Their ages ranged from 18 to 29 giving a mean age of 25 years. Patients were then subjected to radiologic and clinical assessments for a period of at least 33.5 months. For pain scoring the Americans Orthopaedic Foot and Ankle Society (AOFAS) scores were used; whilst subjective symptom was evaluated using the Olerud and Molander ankle scoring system.

Results

All patients returned for the final evaluation and subjective excellent or good results were recorded on self-assessment, pain scores, AOFAS and Karissons scores. Additionally Olerud and Molander ankle scoring was also done. During the final follow-up, the mean post-operative AOFAS score was 96 (range 80–100), the Visual analog score was 6 (range 0–4), Karissons score was 94.7 (range 80–100) and last but not least Olerud and Molander score was 87.5 (range 70–100). It was noted that the ankle range of motion was not affected by lateral ankle reconstruction. The talar tilt was reduced from a mean of 12–4° (p < 0.0001) and the anterior drawer was reduced from a mean of 11–4 mm (p < 0.001) by the ankle ligament reconstruction.

Conclusion

Anatomical reconstruction of the lateral ligaments of chronic ankle instability using Gracillis tendon graft resulted in successful results, excellent ankle stability, significant reduction in pain and negligible loss of ankle and hind foot motion.     

Peroneus longus tendon rupture: A case report

BACKGROUND Peroneal tendinopathies are an under-diagnosed and potentially under-treated pathology. If left untreated it can be a cause of chronic lateral hindfoot pain. Its diagnosis is challenging owing to its low incidence and vague clinical presentation.CASE SUMMARY We share a case of a patient who experienced a chronic lateral ankle pain exacerbated after alighting from a bus. This patient came to our attention only after failing conservative management on two separate occasions. Plain radiographs and magnetic resonance imaging revealed rupture of the peroneus longus tendon(PLT). Findings were confirmed intra-operatively and tenodesis of the PLT to the peroneus brevis was performed. Patient was kept non-weight-bear with his foot everted and in plantarflexion before being converted to an offloading boot at two weeks. Patient was started on a progressive rehabilitation programme at six weeks and was able to return to work shortly after with excellent outcomes.CONCLUSION We aim to share our experience in managing this patient and propose some pointers guided by available literature to avoid missing this commonly overlooked pathology.     

Surgical reconstruction for chronic lateral instability of the ankle

We have treated 56 patients (56 ankles) for symptomatic chronic lateral ankle instability by the surgical reconstruction procedure. The operation included lateral shift of the entire lateral capsule-ligament complex, suture to anterior border of fibula, and reinforcement by an elevated periosteal flap of distal fibula. These patients were reviewed at a mean period of 3.1 years (range, 9 months to 5 years) after the operation. There were 29 males and 27 females with an average age of 29 years (range, 16-49 years). The clinical results were graded according to the AOFAS Ankle-Hindfoot scales. There were 35 patients who were excellent (above 90 points), 16 who were good (between 76 and 90 points), 4 who were fair (between 60 and 75 points), and 1 who was poor (below 60 points). The excellent and good results amounted to 91.1% (51/56). Therefore, we concluded that symptomatic chronic lateral ankle instability could be successfully managed with this easy and effective surgical reconstruction method.     

Delayed reconstruction of lateral complex structures of the ankle

Lateral ankle instability is one of the most common and well-recognized conditions presenting to foot and ankle surgeons. It may exist as an isolated entity or in conjunction with other concomitant pathology, making it important to appropriately diagnose and identify other conditions that may need to be addressed as part of treatment. These associated conditions may be a source of chronic pain, even when the instability has been appropriately treated, or may lead to failure of treatment by predisposing the patient to ankle inversion injuries. The primary goal of this editorial is to provide a brief summary of the common techniques used in the delayed reconstruction of lateral ankle ligamentous injuries and present a method we have successfully employed for over 15 years. We will also briefly discuss the diagnosis and treatment of the more common associated conditions, which are important to identify to achieve satisfactory results for the patient. We present the outcomes of 250 consecutive reconstructions performed over the last 10 years and describe our operative technique for addressing lateral ankle ligamentous injuries.

MRI appearance of the lateral fibulotalocalcaneal ligament complex injury in the patients with chronic lateral ankle instability

BackgroundThe anterior talofibular ligament (ATFL) comprises the superior and inferior fascicles. The inferior fascicle is connected to the calcaneofibular ligament, and forms “lateral fibulotalocalcaneal ligament (LFTCL) complex”. This study aimed to evaluate the feasibility of diagnosing LFTCL complex injuries in patients with chronic lateral ankle instability (CLAI).MethodsForty-eight ankles (35 with CLAI and 13 without CLAI) underwent arthroscopic surgery, and preoperative magnetic resonance imaging (MRI) was conducted with 0.8 mm- thick axial and oblique slices. The diagnostic accuracy of injuries to the superior fascicle and LFTCL complex was evaluated by two observers.ResultsThe sensitivity and specificity of the LFTCL complex injury were 94.7% and 92.3% for observer 1 and 84.2% and 84.6% for observer 2, respectively.ConclusionsMRI with 0.8 mm slices could detect LFTCL complex injury in patients with CLAI. Diagnosing the LFTCL complex injury on MRI will improve outcomes of an arthroscopic isolated ATFL repair.
