Background. Cartilage lesions in chronic lateral ligament deficiency are common with the incidence rates mentioned in the previous literature up to 30%. However, other intra-articular pathologies in the unstable ankle have received little attention. Anterolateral impingement associated with synovitis and scarring is a less recognised feature in the treatment of chronic instability. The aim of our study was to ascertain the incidence of chondral and anterolateral impingement lesions in the symptomatic lateral ligament complex deficiency. Methods. We performed a retrospective study of all consecutive patients who underwent modified Brostrom repair for symptomatic recurrent instability of the ankle. All patients underwent a MRI scan prior to surgery. Arthroscopy was performed in all the patients before lateral ligament reconstruction. Seventy seven patients with 78 ankles were included in the study. Patients who had previous ankle surgery or inflammatory arthropathy were excluded. Data was obtained from clinical and radiological records. Arthroscopic findings were recorded in detail during the surgery. Results. The mean age was 29.8 years (Range 18.2 – 58 yrs). There were 44 females and 34 males in the study. The incidence of chondral lesions were 11.5% (9 out of 78 ankles). The commonest site for chondral defect was the anteromedial talar dome. The incidence of anterolateral impingement which required arthroscopic debridement was 48.7% (38 ankles). A further 10 ankles revealed non-specific synovitis and scarring which was debrided. The sensitivity and specificity of the MRI scans in the assessment of chondral lesions is 91% and 100%. Conclusion. The incidence of chondral lesions in chronic ankle instability is lower than previously published literature. However, soft tissue impingement lesions have a much higher incidence and require debridement. Arthroscopic examination and debridement of impingement prior to lateral ligament reconstruction of the ankle is quintessential in the management of chronic anterolateral instability

The diagnosis of Osteochondral Chondral Lesion of the talar dome is ever more regularly made. Though algorithms of management have emerged by recognising the position, size and the most reliable treatment options, the problem of the failed or relapsed case has only been considered in limited publications. When considering the failed case a variety of possibilities have to be considered. The characteristics of the patient have to be considered. The nature of the original presentation and the history of the present as opposed to the past compliant are worth noting. Patients who have no history of trauma do seem to have a different natural history and response to treatment. The young and the old may well respond differently. Factors preventing recovery from surgery such as ongoing instability of the ankle or hindfoot deformity creating on going abnormal pressures on the joint surface should be looked for. The possibility that the surgery undertreated or missed the full nature of the lesion has to be considered. The possibility of an untreated further pathology should be reviewed. The severity of the original lesion and it's likely response to treatment should be considered. Larger cystic lesions would be more likely to have a poorer outcome. Ultimately if there are persistent symptoms and evidence of ongoing unresolved pathology on the joint surface alternative techniques to resurface the joint should be considered

Aims

The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications.

Aims

The aims of this study were to evaluate the morphology of the ankle in patients with an osteochondral lesion of the talus using 3D CT, and to investigate factors that predispose to this condition.

We investigated the clinical and radiological outcome after unilateral fracture of the lateral process of the talus in 23 snowboarders with a mean follow-up of 3.5 years (12 to 76 months). In this consecutive cohort study both operative and non-operative cases were considered.

The mean American Orthopaedic Foot and Ankle Society hindfoot score was 94 (82 to 100). The non-operative group of seven with a minimally-displaced fracture scored higher (98 points) than the operative group of 16 with displaced or unstable fractures (93 points). In 88% of operative cases, significant concomitant hindfoot injuries were found at operation. All but eight (35%) patients (six operative and two non-operative) regained their pre-injury level of sporting activity. Subtalar osteoarthritis was present in nine (45%) of the 20 patients available for radiological review, including one late-diagnosed non-operative case and eight operative cases with associated injuries or fracture comminution.

The outcome after fracture of the lateral process of the talus in snowboarders is favourable provided an early diagnosis is made and adequate treatment, which is related to the degree of displacement and associated injuries, is undertaken.

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration.

In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

There are few reports of the surgical treatment for late stage Freiburg’s disease with flattening of the metatarsal head and osteoarthritis. We describe the results of the surgical treatment of ten consecutive patients with advanced stage Freiburg’s disease (Smillie’s stage V), using a technique that has not been published previously.
