The aim of this study was to evaluate the time of return to play of elite basketball and voleyball players (both grouped together as jumper) with Haglund deformity after surgical resection of the prominence in the postero-superolateral aspect of the calcaneum. Haglund deformity is a prominence in the postero superolateral aspect of the calcaneum, causing a painful bursitis, which may be difficult to treat by non-operative techniques. In this study, we evaluated the duration that is needed to reach a level that a player perform regularly in a competition. This study consists of players operated by the same surgeon with same technique from 2011 to 2019. Twenty eight feet of 22 patients underwent resection of Haglund deformity with lateral approach and the outcome was analysed using AOFAS Ankle-Hind Foot Scale for hindfoot and time to restart a full range regular training was reported. All players received one dose (5–6 cc) platelet rich fibrin to attachement site of Achilles tendon peroperatively just after decompression of prominence. The mean AOFAS score at the follow up was 90/100, at the end of first year and the majority of players returned to play at 4th to 8th month of follow-up. Only two players with deformity of three feet could start to perform after one year. We conclude that minimal invasive approach ostectomy is an effective treatment for players suffering from Haglund deformity and the results were from good to excellent. However, the player should be well informed that the recovery and returning to play can take a longer time than they expect

Introduction

The BOAST (British Orthopaedic Association Standards for Trauma) guidelines do advise that open pilon fractures amongst other open lower limb fractures need to be treated at a specialist centre with Orthoplastic care. The purpose of this study was to determine clinical outcomes in patients with open pilon fractures treated as per BOAST guidelines including relatively aggressive bone debridement.

Chronic Achilles tendinopathy is characterised by sub-acute inflammation with pro-inflammatory type 1 macrophages (M1), tissue degeneration and consequent partial or total tendon injury. Control of the inflammatory response and M1-to-M2 macrophage polarisation can favour tendon healing both directly and indirectly, by allowing for the regenerative process driven by local mesenchymal stem cells. Ten patients (3 females and 7 males aged between 32 and 71 years old) with partial Achilles tendon injury were treated with injections of autologous peripheral blood mononuclear cells (PB-MNCs). The cell concentrate was obtained from 100-120 cc of each patient's blood with a selective point-of-care filtration system. PB-MNCs remained trapped in the filter and were injected immediately after sampling. Around 60% of the PB-MNC concentrate was injected directly into the injured area, while the remaining 40% was injected in smaller amounts into the surrounding parts of the Achilles tendon affected by tendinosis. All patients were evaluated both clinically with the help of the American Orthopaedic Foot & Ankle Society (AOFAS) scale, and radiologically (MRI examination) at baseline and 2 months after the PB-MNC injection. A clinical reassessment with the AOFAS scale was also performed 6 months after the intervention. The rehabilitation protocol implied full weight-bearing walking immediately after the procedure, light physical activity 3-4 days after the injection, and physiotherapist-assisted stretching exercises and eccentric training. In all patients, functional and radiological signs of tendon healing processes were detected as early as 2 months after a single treatment and the AOFAS scale rose from the initial mean value of 37.5 (baseline) to 85.4 (6 months). Our preliminary results indicate that regenerative therapies with PB-MNCs can prove useful for partial Achilles tendon injuries as a valid alternative to surgical options, especially when other conservative approaches have failed. Advantages of this therapy include rapid execution, no need for an operating theatre, easy reproducibility, quick recovery and good tolerability regardless of the patient's age (the procedure is not to be performed in subjects who are below 18 years old). Further studies on the topic are recommended to confirm these observations

Fragility ankles fractures in the geriatric population are challenging to manage, due to fracture instability, soft tissue compromise, patient co-morbidities. Traditional management options include open reduction internal fixation, or conservative treatment, both of which are fraught with high complication rates. We aimed to present functional outcomes of elderly patients with fragility ankle fractures treated with tibiotalocalcaneal nails. 171 patients received a tibiotalocalcaneal nail over a six-year period, but only twenty met the inclusion criteria of being over sixty and having poor bone stock, verified by radiological evidence of osteopenia or history of fragility fractures. Primary outcome was mortality risk from co-morbidities, according to the Charlson co-morbidity index (CCI), and patients’ post-operative mobility status compared to pre-operative mobility. Secondary outcomes include intra-operative and post-operative complications, six-month mortality rate, time to mobilisation and union. The mean age was 77.82 years old, five of whom are type 2 diabetics. The average CCI was 5.05. Thirteen patients returned to their pre-operative mobility state. Patients with low CCI are more likely to return to pre-operative mobility status (p=0.16; OR=4.00). Average time to bone union and mobilisation were 92.5 days and 7.63 days, respectively. Mean post-operative AOFAS ankle-hindfoot and Olerud-Molander scores were 53.0 (range 17-88) and 50.9 (range 20-85), respectively. There were four cases of broken distal locking screws, and four cases of superficial infection. Patients with high CCI were more likely to acquire superficial infections (p=0.264, OR=3.857). There were no deep infections, periprosthetic fractures, nail breakages, non-unions. TTC nailing is an effective treatment methodology for low-demand geriatric patients with fragility ankle fractures. This technique leads to low complication rates and early mobilisation. It is not a life-changing procedure, with many able to return to their pre-operative mobility status, which is important for preventing the loss of socioeconomic independence

Lisfranc injuries are uncommon and can be challenging to manage. There is considerable variation in opinion regarding the mode of operative treatment of these injuries, with some studies preferring primary arthrodesis over traditional open reduction and internal fixation (ORIF). We aim to assess the clinical and radiological outcomes of the patients treated with ORIF in our unit. This is a retrospective study, in which all 27 consecutive patients treated with ORIF between June 2013 and October 2018 by one surgeon were included with an average follow-up of 2.4 years. All patients underwent ORIF with joint-sparing surgery by a dorsal bridging plate (DBP) for the second and third tarsometatarsal (TMT) joint, and the first TMT joint was fixed with trans-articular screws. Patients had clinical examination and radiological assessment, and completed American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Foot Function Index (FFI) questionnaires. Our early results of 22 patients (5 lost to follow-up) showed that 16 (72%) patients were pain free, walking normally without aids, and wearing normal shoes and 68% were able to run or play sports. The mean AOFAS midfoot score was 78.1 (63–100) and the average FFI was 19.5 (0.6–34). Radiological assessment confirmed that only three patients had progression to posttraumatic arthritis at the TMT joints though only one of these was clinically symptomatic. Good clinical and radiological outcomes can be achieved by ORIF in Lisfranc injuries with joint-sparing surgery using DBP

Introduction and Objective. Despite the low incidence of pilon fractures among lower limb injuries, their high-impact nature presents difficulties in surgical management and recovery. Current literature includes a wide range of different management strategies, however there is no universal treatment algorithm. We aim to determine clinical outcomes in patients with open and closed pilon fractures, managed using a treatment algorithm that was applied consistently over the span of this study. Materials and Methods. This retrospective study was conducted at a single institution, including 141 pilon fractures in 135 patients, from August 2014 to January 2021. AO/OTA classification was used to classify fractures. Among closed fractures, 12 had type 43A, 18 had type 43B, 61 had type 43C. Among open fractures, 11 had type 43A, 12 had type 43B, 27 had type 43C. Open fractures were further classified with Gustilo-Anderson (GA); type 1: n=8, type 2: n=10, type 3A: n=12, type 3B: n=20. Our treatment algorithm consisted of fine wire fixator (FWF) for severely comminuted closed fractures (AO/OTA type 43C3), or open fractures with severe soft tissue injury (GA type 3). Otherwise, open reduction internal fixation (ORIF) was performed. When required, minimally invasive osteosynthesis (MIO) was performed in combination with FWF to improve joint congruency. All open fractures, and closed fractures with severe soft tissue injury (skin contusion, fracture blister, severe oedema) were initially treated with temporary ankle-spanning external fixation. For all open fracture patients, surgical debridement, soft tissue cover with a free or pedicled flap were performed. For GA types 1 and 2, this was done with ORIF in the same operating session. Those with severe soft tissue injury (GA type 3) were treated with FWF four to six weeks after soft tissue management was completed. Primary outcome was AOFAS Ankle-Hindfoot score at 3, 6 and 12-months post-treatment. Secondary outcomes include time to partial weight-bear (PWB) and full weight-bear (FWB), bone union time. All complications were recorded. Results. Mean AOFAS score 3, 6, and 12 months post-treatment for open and closed fracture patients were 44.12 and 53.99 (p=0.007), 62.38 and 67.68 (p=0.203), 78.44 and 84.06 (p=0.256), respectively. 119 of the 141 fractures healed without further intervention (84.4%). Average time to bone union was 51.46 and 36.48 weeks for open and closed fractures, respectively (p=0.019). Union took longer in closed fracture patients treated with FWF than ORIF (p=0.025). On average, open and closed fracture patients took 12.29 and 10.76 weeks to PWB (p=0.361); 24.04 and 20.31 weeks to FWB (p=0.235), respectively. Common complications for open fractures were non-union (24%), post-traumatic arthritis (16%); for closed fractures they were post-traumatic arthritis (25%), superficial infection (22%). Open fracture was a risk factor for non-union (p=0.042; OR=2.558, 95% CI 1.016–6.441), bone defect (p=0.001; OR=5.973, 95% CI 1.986–17.967), and superficial infection (p<0.001; OR=4.167, 95% CI 1.978–8.781). Conclusions. The use of a two-staged approach involving temporary external fixation followed by definitive fixation, provides a stable milieu for soft tissue recovery. FWF combined with MIO, where required for severely comminuted closed fractures, and FWF for open fractures with severe soft tissue injury, are safe methods achieving low complication rates and good functional recovery

Purpose. To evaluate the clinical results of arthroscopic repair and open Ahlgren Larsson method in patients with chronic lateral ankle instability. Methods. We retrospectively evaluated 87 patients who were operated in our clinic between 2010 and 2018 with the diagnosis of chronic lateral ankle instability. 16 patients with osteochondral lesion, 5 patients with rheumatoid arthritis, 4 patients with ankle fractures of the same side, 2 patients with a history of active or previous malignancy were excluded. Preoperative and postoperative clinical evaluations were performed with AOFAS ankle-hindfoot score, FAOS and VAS scores. Results. Sixty patients with chronic lateral ankle instability were evaluated. 28 patients, treated with Ahlgren-Larsson method and 32 patients, treated with arthroscopic repair. 36 of the patients were female and 24 were male; the mean age of the arthroscopy group was 44 ± 9; the mean age of the open surgery group was 46 ± 11. There was no significant difference between the groups in terms of demographic features (age, sex, VKI). Postoperative clinical improvement was observed in both groups. There was no statistically significant difference between the groups in terms of functionality. However, there was a statistically significant difference in pain and satisfaction of VAS in favor of arthroscopy group. Conclusions. Ahlgren-Larsson method and arthroscopic repair technique are safe and effective for chronic lateral ankle instability. Arthroscopic technique may be preferred for pain and patient satisfaction as it is less invasive and less morbid

Background and aims. Hallux rigidus in the metatarsophalangeal joint (MTPJ) can be treated with arthroplasty to reduce pain and enhance motion. Few studies have investigated the functionality and the survival of HemiCap arthroplasty. Primarily we aimed to examine the medium to long-term functionality and the degree of pain after surgery. Secondarily the failure and revision rate of HemiCap implants. Methods. A total of 106 patients were operated with HemiCap arthroplasty (n=114) from 2006 to 2014, median age 53 (16 to 80) years, 78 females, 37 dorsal flange (DF) implants. Patient charts were reviewed retrospectively to collect revision data. Pre operative Coughlin/Shurnas arthrosis degree, hallux valgus (HV), intermetatarsalintermetatarsal (IM) and Distal Metaphyseal Articular Angle (DMAA) angles was were measured. Pre- and post operative 3 weeks, 6 months, 1 and 2 year2-year pain levels of the first MTPJ by Visuel Analog Skala (VAS 1–10), American Orthopaedic Foot and Ankle Score (AOFAS 0 to 100 points) and, Range of Motion (ROM), were available for 51 patients. FortysevenForty-seven of the 70 available for reexamination partook in a cross sectional follow up where the Self-Reported Foot and Ankle Score (SEFAS 0–48 points) was added to the Patients Related Outcome Measures (PROMs). Statistics. Kaplan-Meier for survival analysis, adjusted for sex, radiological angles, degree of arthrosis and dorsal flange. Prospective PROMs and ROM compared by paired t-test. Results. At 3, 5 and 7 years we had an mean implant survival of 85%, 83% and 78%. Almost all were revised due to pain, one due to malalignment and one due to loosening of the Hemicap. Dorsal flange, gender, preoperative arthrosis degree, HV, IM or DMAA angles did not statistically influence the result. For those (n=23) that were re-examined, preoperative dorsal ROM changed from mean(sd) 21 (6) to 42 (18) degrees, VAS from 7 (2) to 2 (2) and AOFAS from 61 (11) to 87 (11) (p < 0.001). At mean 5 year follow up (n=47), mean (sd) dorsal ROM was 46 (17) degrees,. AOFAS was 84 (9), VAS 2 (1) and SEFAS 42 (6) points. The dorsal flange made no statistical significant difference for ROM or PROMs, but DF displayed 51 degrees of extension vs. 44 without (p=0.1). Periprostethic lucency (<2 mm) was observed in 27/47. Conclusions. In general, we saw an acceptable implant survival rate. We did not find any predictors that influenced implant failure and the design alterations with the dorsal flange are not evident clinically. Patients who were not revised had significantly less pain, greater ROM, and better overall foot and ankle conditions than preoperatively, but the data are biased by missing numbers and revisions

Introduction. The management of adolescent hallux valgus (AHV) remains controversial, with reservations about both conservative and surgical treatments. Non-operative management has a limited role in preventing progression. Surgical correction of AHV has, amongst other concerns, been associated with a high prevalence of recurrence of deformity after surgery. We conducted a systematic review to assess clinical and radiological outcomes following surgery for AHV. Methods & Materials. A comprehensive literature search was performed in the Cochrane Library, CINAHL, EMBASE, Google Scholar, and Pubmed. The study was performed in accordance with the recommendations of the PRISMA guidelines. Demographic data, radiographic parameters, and results of validated clinical scoring system were analysed. Results. Nine contemporary studies reporting on 201 osteotomies in 140 patients were included. The female to male ratio was 10:1. Mean age at operation was 14.5 years (10.5–22). Mean follow-up was 41.6 months (12–134). The mean post-operative AOFAS score was 85.8 (sd ±7.38). The mean AOFAS patient satisfaction showed that 86% (sd ± 11.27) of patients satisfied or very satisfied with their outcome. On the DuPont BRS, 90% rated their outcome as good or excellent. There was a statistically significant improvement in the IMA (p=0.0003), HVA (p<0.0001), and DMAA (p=0.019). The main complication was persistent pain (12%); others included infection (2%), scar hypersensitivity (4.5%), and non-union, metatarsalgia, and CRPS (each at 0.5%), and no reports of metatarsal head AVN. Conclusion. Based on the most current published evidence, surgery for AHV shows excellent clinical and radiological outcomes, with high patient satisfaction. The rates of recurrence and other complications are lower than the historically reported figures. There is, however, a need for high level, multi-centre collaborative studies with prospective data to establish the long-term outcomes and optimal surgical procedure(s)

Total ankle replacement (TAR) is increasingly used in the treatment of end-stage ankle arthropathy, but much debate exists about the clinical result. The goals of present study are: 1) to provide an overview of the clinical outcome of 58 TAR's in a single centre and 2) to assess the association between radiological characteristics and clinical outcome. We reviewed a prospective included cohort of 58 TAR's in 54 patients with a mean age of 66.9 (range 54–82) and a mean follow-up of 21.6 months (range 1.45–66.0). The TAR's where performed by a single surgeon in a single centre (MUMC) between 2010 and 2015, using the CCI ankle replacement. A standard surgical protocol and standardized post-op rehabilitation was used. Patients were followed-up pre-op and at 1 day, 6 weeks, 3–6–12 months and yearly thereafter post-op. The AOFAS and range of motion (ROM) were assessed and all complications, re-operations and the presence of pain were recorded. Radiographic assessment consisted of the estimation of prosthesis alignment, migration, translation and radiolucent lines using the Rippstein protocol (1). The clinical outcome was compared with a systematic review of TAR outcome. Ten intra-operative complications occurred and 9 were malleolar fractures. Post-operative complications occurred in 20 out of the 54 patients (37.0%). Impingement (5/54 patients), deep infection (4/54 patients), delayed wound healing (3/54 patients) and minor nerve injuries (3/54 patients) were the most frequently recorded. 18 patients (31.0%) underwent one or more re-operations and 12 of these 18 patients underwent a component revision (mostly the PE insert) or a conversion to arthrodesis. Despite the complications and revisions, the functional outcome improved. Radiologically 15.8% of the TAR's were positioned in varus and 1.8% in valgus. Migration in the frontal and sagittal plane is seen in 3 and 2 TAR's respectively. Radiolucency is significantly increasing with the follow-up time (p=0.009). Migration in the frontal plane is significantly associated with conversion to arthrodesis (p=0.005) and migration in the sagittal plane to revision of a component or conversion to arthrodesis (p=0.04). Finally, pain is significantly associated with re-operations (p=0.023) and complications (p=0.026). Remarkable is that the clinical outcome is independent of the direct post-op alignment of the TAR. The complication-, re-operation and revision or conversion to arthrodesis rates makes the clinical outcome of TAR still questionable favourable. Especially the complication and re-operation incidences are greater than found in the systematic review. However, it is remarkable that the minor complications and re-operations not related to the TAR are not often mentioned in the literature. Radiographic characteristics could be of value in predicting this clinical outcome and thereby influence the post-operative handling. In conclusion, our results show relatively high incidences of complications (37.0%) and re-operations (31.0%) when minor complications and re-operations are included. TAR clinical outcome can be predicted by radiographic migration characteristics and pain

Ankle lateral ligament complex injury is common. Traditional ‘Brostrum’ repair, performed either open or arthroscopically, still has a protracted post-operative period. The ‘Internal Brace’ provides a scaffold for the ligament repair and acts as a ‘check-rein’ preventing further injury. 16 patients with ankle instability and injury to the Anterior-Talo-Fibular-Ligament (ATFL) confirmed on MRI were identified. All had completed a period of conservative treatment. All had symptoms of pain in the region of the ATFL and described a feeling of instability. Surgery was performed under general anaesthetic and regional popliteal block. Anterior ankle arthroscopy demonstrated a positive ‘drive through’ in all cases. The ATFL was absent and in the majority replaced by incompetent scar. Scar tissue was removed from the anterior aspect of the ankle allowing visualisation of the fibula and lateral talar neck. Using the Internal Brace system (Arthrex), a 3.5mm swivel-lock with fibre-tape was placed into the fibula. With the ankle in plantar flexion, to allow appropriate tensioning, the distal end of the fibre-tape was secured to the talar neck, at a 45 degree angle, with a 4.75mm biotenodesis screw. The patient was placed into a moon-boot for 7–10 days and mobilised fully weight-bearing. Pre-op score, using EDQ-5, MOXFQ, AOFAS and visual analogue scores, with post-op PROMS were performed. All patients reported improvement in their symptoms at 6 week visit. The majority were back to normal activities at 12 weeks. The few that were not, had missed physiotherapy appointments for various reasons. There were no infections and no implant failures. Arthroscopy allows direct visualisation for accurate placement of the Internal Brace. Post-operatively recovery is expedited due to the stability provided by the ‘Brace’, permitting a more aggressive rehabilitation programme. The greatest potential is arguably for the elite athlete, where an accelerated return to full activity has significant occupational implications

Summary. Movement analysis (IMA) and activity monitoring (AM) using a body-fixed inertia-sensor can discriminate patients with ankle injuries from controls and between patients of different pathology or post-injury time. Weak correlations with PROMs show its added value in objectifying outcome assessment. Introduction. Ankle injuries often result in residual complaints calling for objective methods to score outcome alongside subjective patient-reported outcome measures (PROMs). Inertial motion analysis (IMA) and activity monitoring (AM) using a body-fixed sensor have shown clinical validity in patients suffering knee, hip and spine complaints. This study investigates the feasibility of IMA and AM 1) to differentiate patients suffering ankle injuries from healthy controls, 2) to compare different ankle injuries, 3) to monitor ankle patients during recovery. Methods. 32 patients suffering ankle problems (ankle sprain, n=17, 42 ±26yrs; operatively managed ankle fracture, n=15, 44 ±17yrs) during short-term recovery (6weeks to 3months post-trauma) were compared to 22 matched healthy controls (41 ±13yrs). Function was measured using IMA: Gait, Sit-Stand (STS) and 10s one-leg Balance test (OLB) were performed while wearing a 3D inertia-sensor at the lower back. Physical activity was measured during 4 successive days using a 3D accelerometer (AM), attached at the upper leg. Validated algorithms were used to derive motion parameters (e.g. speed for gait, bending angle for STS, sway area for OLB, # steps for AM). Moreover three ankle specific questionnaires were completed: Manchester-Oxford Foot and Ankle Questionnaire (MOXFQ), Foot and Ankle Ability Measure (FAAM), AOFAS ankle-hindfoot score. Data was analysed using paired t-tests, one-way ANOVA and Pearson's r. Results. Both patient groups performed worse in function (IMA), activity (AM) and scales (PROM). Even at 3 months mean walking speed (−26%) and cadence (−9%) were slower while pelvic obliquity during ST (+18%) and sway during OLB (+230%) was higher than in controls (p<0.05). Activity was less regarding step/day (−31%) and sit-stand transfers (−11%, p<0.05). Also PROMs were significantly worse in patients (range 17–37%). Comparing in-between patients, significant differences were found in PROMs and function (IMA) with fracture patients walking slower (−30%) or showing more sway during one-legged balance (+250%). Mean activity scores (steps, bouts, cadence) were also less for fractures (p>0.05). During recovery, PROMs improved significantly, while function (IMA) and activity (AM) only showed small or selective improvements (e.g. 8° reduction in bending angle during ST, 20% increase in cadence). Only weak to moderate correlations were found between PROM, IMA (r-range: 0.32–0.79) and AM parameters (r-range: 0.31–0.71). Discussion & Conclusion. Function, physical activity and PROMs were impaired in patients with ankle injuries compared to healthy subjects, with the fracture group performing worse on IMA and PROMs than the sprain group. In this first study ever to measure activity in ankle patients, it was shown that e.g. fracture patients walk ca. half as many steps and bouts as age-matched controls even though at 6weeks they were unable to walk 20m without walking aids (floor effect of IMA function test). The lack of improvements in IMA and AM during recovery while PROMs improved significantly, together with the few and only weak-to-moderate correlations between PROMs, IMA and AM shows that subjective and objective recovery differ and highlight the added value of IMA and AM for objectifying routine clinical outcome assessment
