Posterior tibial tendon dysfunction (PTTD) is a common pathology of the foot and ankle. Numerous techniques are available to reconstruct the flatfoot. Fusions and tendon transfers are popular methods; however, a wide range of complications have been associated with these procedures. The objective of the present study was to demonstrate the outcomes of reconstructive surgery for flatfoot correction without tendon transfer or arthrodesis. We performed a retrospective study of 43 patients and 56 feet who had undergone flatfoot reconstructive surgery from November 2011 to June 2016, with a mean follow-up period of 60 weeks (range 12 to 60 months)...

The primary human ankle plantarflexors, soleus (SO), medial gastrocnemius (MG) and lateral gastrocnemius (LG), are typically regarded as synergists and play a critical role in running. However, due to differences in muscle-tendon architecture and joint articulation, the muscle fascicles and tendinous tissue of the plantarflexors may exhibit differences in their behaviour and interactions during running. We combined in-vivo dynamic ultrasound measurements with inverse dynamics analyses to identify and explain differences in muscle fascicle, muscle-tendon unit (MTU) and tendinous tissue (SEE) behaviour of the primary ankle plantarflexors across a range of steady-state running speeds...

BACKGROUND: Tibialis posterior (TP) tendon transfer is an effective treatment for foot drop. Currently, standard practice is to immobilize the ankle in a cast for 6 weeks nonweightbearing, risking postoperative stiffness. To assess whether early active dorsiflexion and protected weightbearing could be safe, the current study assessed tendon displacement under cyclic loading and load to failure, comparing the Pulvertaft weave (PW) to interference screw fixation (ISF) in a cadaveric foot model...

BACKGROUND: Simultaneous motion of the knee and ankle joints is required for many activities including gait. We aimed to evaluate the influence of surgery involving tendons around the knee on ankle motion during gait in the sagittal plane in cerebral palsy patients. METHODS: We included data from 55 limbs in 34 patients with spastic cerebral palsy. Patients were followed up after undergoing only distal hamstring lengthening with or without additional rectus femoris transfer...

BACKGROUND: Tibialis posterior tendon transfer is performed when loss of dorsiflexion has to be compensated. We evaluated the circumtibial (CT), above-retinaculum transmembranous (TMAR), and under-retinaculum transmembranous (TMUR) transfer gliding resistance and foot kinematics in a cadaveric foot model during ankle range of motion (ROM). METHODS: Eight cadaveric foot-ankle distal tibia specimens were dissected free of soft tissues on the proximal end, applying an equivalent force to 50% of the stance phase to every tendon, except for the Achilles tendon...

BACKGROUND: Tibialis anterior tendon ruptures are rare and can cause significant dysfunction. Often, conservative measures are prescribed because of the morbidity of a tendon transfer as an operative solution. We present a novel reconstruction technique using hamstring autograft, which may obviate the need for local tendon transfer and long-term bracing. METHODS: Patients who underwent tibialis anterior reconstruction with hamstring autograft between 2011 and 2015 were screened for inclusion...

BACKGROUND: Repairs of chronic Achilles tendon ruptures are technically challenging due to large defects after scar excision. Multiple techniques for repair have been proposed but little consensus on best practice established. This study aims to compare flexor hallucis longus (FHL) transfers versus turndown flaps augmented by FHL transfers. METHODS: Between 2005 and 2015, 49 unilateral repairs of chronic Achilles tendon ruptures were performed. We retrospectively compared the outcomes of 20 patients who underwent FHL transfer with 19 patients who underwent turndown flaps augmented with FHL transfer before surgery and at three time points after surgery (three, six and twelve months)...

CASE: A 47-year-old Caucasian woman spontaneously developed an isolated anterior compartment pressure of >100 mm Hg in the left leg. Despite fasciotomies, the musculature was nonviable and required debridement. Following Achilles tendon lengthening, a posterior tibial tendon (PTT) to anterior tibial tendon (ATT) transfer was supplemented with a flexor digitorum longus tendon transfer to the remaining PTT in order to prevent a flatfoot deformity while restoring active dorsiflexion. CONCLUSION: Preservation of the tendinous portion of the ATT during debridement allowed for transfer of the PTT to the ATT using a modified Pulvertaft transfer...

BACKGROUND: Chronic Achilles tendon ruptures can lead to reduced power of plantar flexion in the ankle with impaired gait ability. The open 1- or 2-incision technique for flexor hallucis longus transfer has proven good functional outcome but has the disadvantage of relatively extensive surgery performed at a vulnerable location. To reduce the risk of soft tissue problems, the flexor hallucis longus transfer can be performed endoscopically. MATERIAL AND METHOD: An endoscopic technique for flexor hallucis longus transfer is presented together with the experiences from the first six patients operated with this method...

BACKGROUND: Restoration of the lateral ankle after distal fibulectomy is a difficult reconstructive procedure. Many surgical techniques have been proposed. This report shows another fibular reconstructive option with promising outcome. CASE PRESENTATION: We report the case of a 30-year-old woman who presented with a solitary mass located in the lateral aspect of the ankle. The mass had grown rapidly for 2 months and caused increasing pain. Physical examination showed a 3...

BACKGROUND: Posterior tibial tendinopathy is a challenging foot condition resulting in pes planus, which is difficult to diagnose in the early stage. Prior to the deformity, abnormal internal load transfer and soft tissue attenuation are anticipated. The objective of this study was to investigate the internal load transfer and strain of the ligaments with posterior tibial tendinopathy, and the implications to pes planus and other deformities. METHODS: A three-dimensional finite element model of the foot and ankle was reconstructed from magnetic resonance images of a 28-year-old normal female...

Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms...

Subtalar joint arthroereisis (SJA) has been introduced to control the hyperpronation in cases of flatfoot. The objective of this study is to evaluate the biomechanical consequence of SJA to restore the internal stress and load transfer to the intact state from the attenuated biomechanical condition induced by posterior tibial tendon dysfunction (PTTD). A three-dimensional finite element model of the foot and ankle complex was constructed based on clinical images of a healthy female (age 28 years, height 165 cm, body mass 54 kg)...

In anterior transfer of the tibialis posterior tendon, the tendon was harvested using two incisions, the first at its attachment point on the navicular bone and second on the medial side of the leg above the medial malleolus. To provide the maximum tendon length, the second incision needs to be as proximal as possible but injury to the muscle origin must be avoided. The purpose of this study is to establish the location of the second incision that yields the greatest tendon length. Forty-five unpaired embalmed cadaveric legs were dissected...

BACKGROUND: Fibular hemimelia is a congenital disorder that is characterized by the absence of the fibula that could be either partial or complete. Successful management aims to restore normal weight bearing and normal limb length. The introduction of the Ilizarov method of limb lengthening has provided an attractive alternative to amputation. During lengthening, the tight posterolateral soft-tissue structures, the thick fibrous fibular band, and the shortened Achilles tendon become tighter and transfer a valgus force to the talus and calcaneus, further aggravating the deformity...
