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...

PURPOSE: The purpose of the study was to evaluate the effect of concurrent arthroscopic osteochondral lesion (OCL) treatment and lateral ankle ligament repair on the outcome of chronic lateral ankle instability. It was hypothesized that the arthroscopic OCL treatment might have some negative effect on the outcome of chronic lateral ankle instability (CLAI) by compromising the rehabilitation program. METHODS: Ankle arthroscopy and anatomic lateral ankle ligament repair with suture anchors were performed for 70 patients with CLAI between 2010 and 2012...

INTRODUCTION: The spring ligament (SL) is increasingly recognised as the major structure that fails in acquired adult flatfoot deformity (AAFD). This is the first study that demonstrates integrity of repair of the SL. PATIENTS AND METHODS: Six pairs of fresh frozen cadavers were setup in a standardised fashion with ankle in plantargrade (mean age 59 years, BMI 25). A 25N lateral force was applied to the medial metatarsal head using an algometer. Lateral displacement of the foot was measured with SL intact, sectioned, following FibreWire(®) repair, then Arthrex InternalBrace (IB) reconstruction, then with selective sectioning of each limb of the IB reconstruction...

OBJECTIVES: Injury to the lateral ligament complex of the ankle is one of the most common sports-related injury. Usually lateral ankle evolves with excellent clinical recovery with non surgical treatment, however, near about 30% develop a lateral chronic instability sequela. Several open and arthroscopic surgical techniques have been described to treat this medical condition. MATERIAL AND METHODS: Of the 22 patients who were treated; 18 males and 4 females, and aged from 17-42 years (mean 28 years)...

The ball-and-socket ankle joint is a rare deformity characterized by the loss of concavity in the trochlear surface of the talus with rounding of the articular surfaces of the distal fibula and tibia. Frequently, tarsal coalitions, fibular hypoplasia, and shortening of the limb accompany this deformity. To date, no data have been reported on surgical treatment of lateral ankle joint instability and peroneal tendon dislocation concomitant with a ball-and-socket ankle joint. In the present study, we report the case of a 43-year-old male patient with right lateral ankle joint instability and peroneal tendon dislocation in a ball-and-socket ankle joint, with accompanying tarsal coalition...

BACKGROUND: One-third of individuals who sustain an acute lateral ankle ligament sprain suffer significant disability due to pain, functional instability, mechanical instability or recurrent sprain after recovery plateaus at 1 to 5 years post injury. The identification of early prognostic factors associated with poor recovery may provide an opportunity for early-targeted intervention and improve outcome. METHODS: We performed a comprehensive search of AMED, EMBASE, Psych Info, CINAHL, SportDiscus, PubMed, CENTRAL, PEDro, OpenGrey, abstracts and conference proceedings from inception to September 2016...

BACKGROUND: The arthroscopic modified Broström operation (MBO) has been frequently used to treat chronic lateral ankle instability (CLAI). However, no reports comparing the clinical outcomes between patients with or without generalized ligamentous laxity (laxity or no laxity, respectively) currently exist. The purpose of this study was to compare the clinical outcomes of the 2 groups with CLAI. METHODS: Between January 2013 and November 2015, arthroscopic MBO was performed on 99 patients with CLAI...

BACKGROUND: Although the peroneal muscles are known to be the major dynamic lateral stabilizers of the ankle, little information is available regarding the change in muscle strength and relation with the outcomes after lateral ligament repair surgery. The purpose of this study was to identify the effects of peroneal strength on the validated functional outcome measures after the modified Broström procedure (MBP) for chronic ankle instability. METHODS: Forty-one patients (41 ankles) who underwent MBP using suture anchors were eligible and followed up to 2 years postoperatively...

BACKGROUND: To assist with visualization, orthopaedic surgeons often apply ankle distraction during arthroscopic procedures. The study aimed to investigate whether ankle distraction suppresses fibular motion in cadaveric specimens with an unstable syndesmotic injury. METHODS: Fourteen fresh-frozen above knee specimens underwent arthroscopic assessment with 1) intact ligaments, 2) after sectioning of the anterior inferior tibiofibular ligament, the interosseous ligament, and the posterior inferior tibiofibular ligament, and 3) after sectioning of the deep and superficial deltoid ligament...

PURPOSE: When the anterior fascicle of the deltoid ligament is injured in patients with chronic ankle instability, the diagnosis of rotational ankle instability is supported. The aim of this study was to report the results of an all-arthroscopic technique to concomitantly repair the lateral collateral and deltoid ligaments to treat patients with rotational ankle instability. METHODS: Thirteen patients [12 men and 1 woman, median age 32 (15-54) years] with rotational ankle instability were treated by arthroscopic means after failing non-operative management...

BACKGROUND: Clinical evidence has shown that percutaneous ankle fracture fixation using an intramedullary fibular nail results in good outcomes at 1 year and reduces postoperative wound complications in patients with vulnerable soft tissues. Confirmatory biomechanical evidence of its strength when used to secure a supination external rotation (SER) IV (AO/OTA 44B-type) fracture, compared with traditional plates and screws, is currently lacking. METHODS: Twenty cadaveric lower limbs (10 cadavers) had a SER IV injury surgically created...

BACKGROUND: Although smoking is known to be harmful to the musculoskeletal system, no studies have investigated its effects on the outcomes of ankle ligament surgery. We determined the effects of smoking on the clinical and radiological outcomes of lateral ankle ligament reconstruction using tendon allografts according to smoking status. METHODS: From among 105 patients with chronic ankle instability who were treated with anatomical reconstruction of the anterior talofibular ligament and the calcaneofibular ligament using semitendinosus tendon allografts and bio-tenodesis screws, 70 ankles, from 23 smokers and 47 non-smokers, were analyzed...

BACKGROUND: Appropriate management of ankle syndesmotic instability is needed to prevent the development of complications. Previous biomechanical studies have evaluated movement of the fibula after screw or suture button fixations with different results, most likely being caused by variations in experimental setups that did not mirror the in vivo clinical setting. This study aimed to arthroscopically compare in a cadaveric model the stability of syndesmotic fixation with either a suture button or syndesmotic screw...

REVIEW
F Molinier, J Benoist, F Colin, J Padiolleau, S Guillo, J Stone, T Bauer
Antero-lateral ankle impingement syndrome (ALAIS) is a well-established clinical entity that is a common consequence of ankle sprains. Injury to the anterior talo-fibular ligament plays a key role in the genesis of ALAIS. Arthroscopic antero-lateral synovectomy is the standard of care. However, this treatment approach may deserve to be challenged, as it does not include any procedure on the ligaments, despite the presence in some patients of lateral rotational micro-instability of the ankle, without objective laxity...

While it is well known that ankle sprains are one of the most common injuries in the United States, predictive factors regarding failure of conservative treatment are not well known. There are many biomechanical and epidemiological factors that play a role in recurrence and failure of conservative treatment, but most cases are able to be treated with immobilization and/or rest, ice, elevation, physical therapy, and bracing. We propose that one important risk factor is often overlooked simply due to the fact that a vast majority of these cases resolve without the need for surgery...
