Introduction. Anterior ankle arthroscopy currently provides the best chance of restricting local anatomy damage during ankle surgery. The anterior working area (AWA) of the ankle is restricted by the Dorsalis Pedis Artery (DPA) and the extensor muscle tendons when the procedure is conducted both in dorsiflexion and plantarflexion. During surgery, iatrogenic damage to the DPA can lead to the formation of a pseudoaneurysm, which can be difficult to identify intraoperatively. Our study investigates whether dorsiflexion or plantarflexion provides variability in the movement of the DPA to determine the positions at which anterior ankle arthroscopy provides the greatest anterior working area (AWA) without causing vascular damage. The current study expects the distance of the DPA from the inferior border of the medial malleolus (IBMM) (ankle joint) to be greater on ankle dorsiflexion than in ankle plantarflexion. Materials and Methods. Twelve cadaver ankles embalmed with a mixture of phenol and glycerol, allowing greater motion, were dissected to access the DPA. The ankles, while in a distracted position (in accordance with common surgical practice), were forced into dorsiflexion from a plantarflexion position at 5° intervals. The distance between the IBMM and the DPA was measured at the 5° intervals. Results. The mean amount of ankle flexion achieved was 24.58° (Range = 20–35). All twelve ankles showed positive range of movement (ROM) anteriorly from the IBMM with a mean ROM of 3.58mm (SE = 0.29mm) dorsiflexion. Discussion and Conclusion. Anterior movement of the Dorsalis Pedis Artery during dorsiflexion puts it at a lower risk of iatrogenic damage in a dorsiflexed position compared to plantarflexion. The increased AWA allows the surgeon more manoeuvrable space, possibly allowing the use of larger diameter surgical instruments

We describe a medial midline portal between the tendons of extensor hallucis longus and tibialis anterior for arthroscopy of the ankle. We dissected 20 cadaver specimens to compare the risk of neurovascular injury using this approach with that of using standard arthroscopic portals. Compared with the anterocentral portal, the medial midline was a mean of 11.2 mm further from the nearest branch of the superficial peroneal nerve and 10.3 mm further from the dorsalis pedis artery.

This portal allows good access to the joint surface and intra-articular structures and has a lower risk of injury to the dorsalis pedis artery, deep peroneal nerve or the medial branch of the superficial peroneal nerve.

Aims

Arthroscopically controlled fracture reduction in combination with percutaneous screw fixation may be an alternative approach to open surgery to treat talar neck fractures. The purpose of this study was thus to present preliminary results on arthroscopically reduced talar neck fractures.

Introduction. Acute ankle injuries are commonly seen in musculoskeletal practice. Surgical management is the gold standard for lateral ligament injury in those with failed conservative treatment for a minimum of six months. Several studies have shown good functional outcome and early rehabilitation after MBG repair with an internal brace augmentation which is a braided ultrahigh molecular weight polyethylene ligament used to enhance the repair that acts as a secondary stabiliser. Hence the aim of the study was to compare the results with and without augmentation. Methods. A single centre retrospective review conducted between November 2017 and October 2019 and this included 172 patients with symptomatic chronic lateral ligament instability with failed conservative management. The diagnosis was confirmed by MRI. All patients had an ankle arthroscopy followed by open ligament repair. Patients were grouped into isolated MBG and internal brace groups for analyses and all had dedicated rehabilitation. Results. A total of 148 patients were available for final follow up with 87 patients in the MBG group and 61 patients in the IBA group. Mean Age was 38 years and mean follow up was 22 months. The internal brace group showed better Manchester Oxford foot and ankle score (19.7 vs 18.2) and more patients returning to preinjury activity levels (73 vs 55) as compared to isolated repair. Conclusion. Internal brace augmentation with MBG repair facilitated early rehabilitation and return to pre injury activity level in majority of patients compared to isolated MBG repair

Background. MRI is the preferred modality for the diagnosis of ankle joint pathology. Musculoskeletal radiologists aim to determine and report both chondral and/or osseous stability/instability of each lesion. The aim of this study was to specifically analyse the reliability of MRI reported findings in predicting the stability of OCL's in symptomatic patients. Methods. A single centre, single surgeon consecutive series of patients who had undergone an ankle arthroscopy procedure preceded by an MRI scan for symptomatic ankle pathology were included in this retrospective clinical study. All MRI scans were reported by a musculoskeletal radiologist. MRI reports and arthroscopic findings were extracted and analysed. Arthroscopy findings were taken as the gold standard. Results. Between April 2012 and July 2016, 48 patients who fulfilled the above criteria were included. There were 27 male and 21 female patients, the average age was 43.4 (SD 14.1). The average time interval between MRI scan and arthroscopy was 9 months (2–49 months), 28 patients (58.3%) had a right sided pathology. There was a significant negative relationship between OCL's reported as stable on MRI to arthroscopic findings, r=−.31, p=0.03. Of the 21 patients who had OCL's reported as stable on the MRI scan, all had unstable lesions on arthroscopic evaluation (100%). One patient had an unstable OCL reported on the MRI scan and it was also found unstable arthroscopically. In 27 patients, where there was no mention of the stability of the reported OCL on the MRI, 22 patients (81.5%) had unstable lesions and 5 patients (18.5%) had stable lesions on intra-operative arthroscopic findings. Conclusion. This study demonstrates that MRI has a poor predictive value for the stability of OCL's of the ankle. Therefore we recommend that in the symptomatic patient an arthroscopy is indicated irrespective of MRI findings. Evidence. retrospective case review, level IV

Introduction:. The National Joint Registry has been capturing data on ankle replacement surgery since April 2010. This currently represents the largest cohort of ankles replacements captured worldwide and is a valuable resource to give us short term outcome of ankle replacement surgery. Methods:. All the ankle replacements on the NJR were linked to the HES database using deterministic methods. The results were then anonymised. We then looked at Hopital admissions after the ankle replacement had taken place. Results:. There were just over 1600 ankles on the NJR and linking to HES gave 2065 records. 1437 of these were relevant to TAR. There were 12 malleolar fractures post-op and 6 DVT/PE which required readmission. there were 49 reoperations other than revision, 12 of which were ankle arthroscopies, and 14 removal of metalwork. Conclusion:. Ankle replacement is a effective procedure but does carry with it the risk of short term reoperation

Aim:. Ankle sprains are one of the most common sports injuries. Around 10–20 % of the acute ankle sprains may lead to the sequelae of chronic ankle instability. Around 15–35% of the patients have residual pain following successful lateral ligament reconstruction. One of the reasons suggested for the persistent symptoms following lateral ligament reconstruction has been the presence of intra-articular pathology. Methods and materials:. We performed ankle arthroscopy on all patients undergoing the modified Brostrom repair and compared patients with associated intra-articular pathology to those without any intra-articular pathology. Results:. A total of 35 patients underwent the modified Brostrom procedure during the study period. 11/25 patients were found to have associated intra-articular pathology. The average age for both the groups was 33 years. The average follow-up duration was 75 months and 71 months for the intra-articular pathology group and the normal articular groups respectively. The difference in the SAFAS (Sports athlete foot and ankle score) was statistically better in the group without any intra-articular pathology (93.7 compared to 71.6, p-value < 0.05). Conclusions:. The patients who have an associated intra-articular pathology whilst undergoing the stabilisation of lateral ligament instability of the ankle have a slightly poorer outcome compared to those without any intra-articular pathology. Secondly, the SAFAS scoring system seems to overcome the ceiling effect seen in other scoring systems when used for the athletic population

Introduction:. The role of total ankle replacements remains unproven within orthopaedic literature. We present a prospective series of patients who underwent a SALTO TAR (Tornier) between October 2006 and January 2014. Methods:. A cohort of 53 TAR (50 patients) were prospectively followed up and assessed clinically, radiologically and asked to complete FAOS, VAS and Modified AOFAS scores. Four patients had bilateral procedures. The mean age was 71 years old (range 42–92). The mean follow up was 55 months (range 6–92). Nineteen TARs (19 patients) have a follow up of more than 60 months. Results:. Our survival rate is 98% as one patient proceeded to have an ankle fusion at 12 months due to loosening. Three patients had ankle arthroscopies at 1 year post TAR; one for removal of a fibula cyst, one for synovitis in the lateral gutter and another for fibula impingement. One patient had an early postoperative infection. Mean overall FAOS scores were 73.4 for the entire cohort and 74.2 for the cohort with over 5 years follow-up. Mean modified AOFAS scores for the entire cohort and the cohort with over 5 years follow up was 71.5 and 78.9 respectively. Mean VAS scores for the entire cohort and the cohort with over 5 years follow-up was 18.8 and 25.8 respectively. Discussion:. Ankle joint arthrodesis has been shown to be a reliable in relieving pain and result in good patient satisfaction. However, total ankle replacement provides an alternative surgical option for the management of ankle arthritis. The improving survivorship of ankle replacements is making this an increasingly popular option. Our follow-up of almost five years as an entire cohort, but also those with over five years, show that these latest generations of TAR have excellent mid term survivorship, accompanied by high levels of patient satisfaction and function

The purpose of this study was to evaluate the early functional outcome of this new modification of the Brostrom-Gould lateral ligament reconstruction using suture anchors and triple breasting of ATFL. AOFAS hindfoot scoring system was the primary outcome measure used. Between January 2008 and May 2011, data was collected prospectively, pre and postoperatively. Surgery for all patients included ankle arthroscopy plus whatever other minor procedure was indicated and was performed by the senior author. Postoperatively at 3 months and 12 months and in May 2011 patients were asked to attend a research clinic and their scores were obtained. Anterior drawer laxity and patient satisfaction, activity resumption and complications were some of the other information recorded. A mean follow up of 25 months on 18 ankles is presented which is amongst the longest in the literature for this procedure. Comparing pre and postoperative AOFAS scores revealed a statistically significant mean improvement of 39 points p < 0.05 with mean preoperative score being 53 and at 25 months being 89. All ankles felt clinically stable on repeated anterior drawer testing. 8 patients had resumed normal pre-injury level of activities (including sports), 8 had some reduction in normal level of activity and 2 did not carry out physical prior to operation. One patient complained of scar tenderness otherwise no complications were noted. 13 patients were extremely satisfied with results of surgery, 4 were very satisfied and 1 was moderately satisfied. The mid-term results of our modification show it to be safe, reproducible and highly successful in producing clinically and functionally stable ankles with high patient satisfaction. This includes a statistically significant improvement in AOFAS scores. This exceeds the results in the published literature
