Introduction. Recurrence in CTEV is not uncommon and as the child becomes older the foot in question is often stiffer and less amenable to the more traditional serial casting Ponseti method. Treatment of these recurrent CTEV feet with external fixators has been previously documented. We aim to present the Sheffield technique of an external circular frame with adjunctive hindfoot and midfoot osteotomies to correct relapsed CTEV and their associated Roye (outcome) scores. Materials and Methods. Retrospective analysis of patient records from 1999 to 2019 were performed for those undergoing frame correction of CTEV. Patients were included if there was adjunctive foot osteotomies in the setting of CTEV frame correction and willingness to partake in retrospective Roye outcome scoring. The Roye score was sent out in the mail to parents asking for scoring of the current level of symptoms. Results. 160 patients were contacted for Roye score evaluation. We successfully collected outcome data for 46 feet in 39 patients. 27 (69%) patients had idiopathic CTEV. Average age at fixator application 12.6 years (range 7–18). Mean length of follow up 10.6 years (1 – 20). 76% of patients were either very (22%) or somewhat (54%) satisfied with the status of their foot. The largest negative score was 61% of parents found difficulty in finding shoes to fit their child's feet after treatment. 39% of patients had significant
Interscalene brachial plexus block is the standard regional analgesic technique for shoulder surgery. Given its adverse effects, alternative techniques have been explored. Reports suggest that the erector spinae plane block may potentially provide effective analgesia following shoulder surgery. However, its analgesic efficacy for shoulder surgery compared with placebo or local anaesthetic infiltration has never been established. We conducted a randomised controlled trial to compare the analgesic efficacy of pre-operative T2 erector spinae plane block with peri-articular infiltration at the end of surgery. Sixty-two patients undergoing arthroscopic shoulder repair were randomly assigned to receive active erector spinae plane block with saline peri-articular injection (n = 31) or active peri-articular injection with saline erector spinae plane block (n = 31) in a blinded double-dummy design. Primary outcome was resting pain score in recovery. Secondary outcomes included pain scores with movement; opioid use; patient satisfaction; adverse effects in hospital; and outcomes at 24 h and 1 month. There was no difference in pain scores in recovery, with a median difference (95%CI) of 0.6 (-1.9-3.1), p = 0.65. Median postoperative oral morphine equivalent utilisation was significantly higher in the erector spinae plane group (21 mg vs. 12 mg; p = 0.028). Itching was observed in 10% of patients who received erector spinae plane block and there was no difference in the incidence of significant nausea and vomiting. Patient satisfaction scores, and pain scores and opioid use at 24 h were similar. At 1 month, six (peri-articular injection) and eight (erector spinae plane block) patients reported
Anterior cruciate ligament (ACL) injuries have been increasing, especially amongst adolescents. These injuries can increase the risk for early-onset knee osteoarthritis (OA). The consequences of late-stage knee OA include structural joint change, functional limitations and
In years past, the most common reason for revision following knee replacement was polyethylene wear. A more recent study indicates that polyethylene wear is relatively uncommon as a cause for total knee revision counting for only 10% or fewer of revisions. The most common reason for revision currently is aseptic loosening followed closely by instability and infection. The time to revision was surprisingly short. In a recent series only 30% of knees were greater than 5 years from surgery at the time of revision. The most common time interval was less than 2 years. This is likely because of the higher incidence of infection and instability that occurs most commonly at a relatively early time frame. Evaluation of a painful total knee should take into account these findings. All total knees that are painful within 5 years of surgery should be assumed to be infected until proven otherwise. Therefore, virtually all should be aspirated for cell count, differential, and culture. Alpha-defensin is also available in cases in which a patient may have been on antibiotics within a month or less, as well as cases in which diagnosis is a challenge for some reason. Instability can be diagnosed with physical exam focusing on mid-flexion instability which can be usually determined with the patient seated and the knee in mid-flexion, with the foot flat on the floor at which point sagittal plane laxity can be discerned. This is also frequently associated with symptoms of giving way and recurring effusions and difficulty descending stairs. A new phenomenon of tibial de-bonding has been described, which can be a challenge to diagnose. Radiographs can appear normal when loosening occurs between the implant and the cement mantle. This seems to be more common with the use of higher viscosity cement. Obviously this is technique dependent since good results have been reported with the use of high viscosity cement. Component malposition can cause stiffness and pain and relatively good results have been reported by component revision when malrotation has been confirmed with CT scan. When infection, instability and loosening are not present, extra-articular causes should be ruled out including lumbar spine, vascular compromise, complex regional pain syndromes and fibromyalgia, and peri-articular causes such as bursitis, tendonitis, tendon impingement among others. One of the most common causes of pain following total knee is unrealistic patient expectations. Performing total knee replacement in early stages of arthritis with only mild to moderate symptoms and radiographic changes has been associated with
Autologous bone has been the gold standard for grafting material in foot and ankle arthrodesis. While autograft use has been effective, the harvest procedure does present risks to the patient including readmission, infection, and persistent graft harvest site pain. Previous studies have examined graft harvest site pain, but most have focused on the iliac crest and none have long term follow-up. The purpose of this study was to examine long-term (7–10 year) harvest site pain in subjects undergoing autograft harvest from multiple sites for hindfoot and/or ankle arthrodesis. Sixty (60) subjects underwent hindfoot or ankle arthrodesis supplemented with autograft as part of the control arm of a prospective, randomized trial. The mean subject age was 59.4 years (range, 24.7–76.8) and mean body mass index was 30.6 kg/m2 (range, 22.0–44.0). There were 29 males and 31 female subjects. Subjects had the tibiotalar (37.9%), subtalar (24.1%), talonavicular (10.3%), subtalar/talonavicular (5.1%), or subtalar/calcaneocuboid/talonavicular (22.4%) joints arthrodesed. Autograft was harvested from either the proximal tibia (51.7%), iliac crest (17.2%), calcaneous (15.5%), distal tibia (6.8%), or other location (8.6%). Graft harvest site pain was evaluated using a 100-point visual analog score (VAS), with clinically significant pain being any score greater than 20. Subjects were followed a mean of 9.0 years (range, 7.8–10.5). The percentage of subjects who reported clinically significant pain was 35.7%, 21.4%, 18.2%, 10.5%, 8.9%, and 5.2% at 2, 6, 12, 24, 52 weeks, and final follow-up (7.8–10.5 years), respectively. The mean VAS autograft harvest site pain at final follow-up was 4.4 (range, 0.0–97.0), with 37.9% of subjects reporting at least some pain. For three subjects (5%) with clinically significant pain (VAS >20) at final follow-up, two had proximal tibial harvest sites and one had an iliac crest harvest site. There was no correlation between graft volume and harvest site pain. This study is the first to examine long-term pain following autologous bone graft harvest for hindfoot and/or ankle arthrodesis. Over a third of patients reported having some pain at an average follow-up of nine years, with 5% experiencing clinically significant pain. The results of this study suggest that harvesting autograft bone carries a risk of
Introduction. Post-meniscectomy syndrome is broadly characterised by intractable pain following the partial or total removal of a meniscus. There is a large treatment gap between the first knee pain after meniscectomy and the eligibility for a TKA. Hence, there is a strong unmet need for a solution that will relieve this post-meniscectomy pain. Goal of this first-in-man study was to evaluate the safety and performance of an anatomically shaped artificial medial meniscus prosthesis and the accompanying surgical technique. Methods. A first-in-man, prospective, multi-centre, single arm clinical investigation was intended to be performed on 18 post-medial meniscectomy syndrome patients with limited underlying cartilage damage (Kellgren Lawrence scale 0–3) in the medial compartment and having a normal lateral compartment. Eventually 5 patients received a polycarbonate urethane mediale meniscus prosthesis (Trammpolin® medial meniscus prosthesis; ATRO Medical B.V., the Netherlands) which was clicked onto two titanium screws fixated at the native horn attachments on the tibia. PROMs were collected at baseline and at 6 weeks, 3, 6, 12 and 24 months following the intervention including X-rays at 6, 12 and 24 Months. MRI scans were repeated after 12 and 24 months. Results. The surgical technique to select the appropriately sized implant and correct positioning of the fixation screws and meniscus prosthesis onto the tibia was demonstrated feasible and reproducible. The surgeries showed that in particular the positioning of the posterior screw is crucial for correct positioning of the prosthesis. Inclusion stopped after 5 patients, who reached the 6 months evaluation. The PROMs did not improve in the first 6 months after surgery. All patients reported knee joint stiffness and slight effusion in their knee at 6 months follow-up. In case of symptomatic patients an evaluation of the device position and integrity was performed by MRI. In three patients the implants were removed because of implant failure and in one patient the implant was removed because of
Acute pain is one of the most common symptoms shared among patients who have suffered from an orthopedic trauma such as an isolated upper limb fracture (IULF). Development of interventions with limited side effects aiming to prevent the installation of chronic pain is critical as
The Oxford mobile bearing knee prosthesis (Zimmer Biomet Inc, Warsaw, Ind) is considered a good treatment option for isolated medial compartment knee arthrosis. From February 2001 until August 2016, 1719 primary Oxford medial unicompartmental knee replacement procedures were completed at our center by a group of seven surgeons. We undertook this study to examine the long-term survivorship of the Oxford unicompartmental knee replacement looking at survivorship and reasons for failure. A retrospective consecutive case series review was completed, and all revisions and re-operations were identified. Conversion to total knee replacement (TKA) was considered a failure. Kaplan-Meier survival analysis was used to calculate the 15-year survivorship of the group overall. We specifically looked at age, gender, BMI and surgeon caseload in addition to the reasons for failure. A statistical analysis was performed and differences in survivorship were compared for the variables listed. A logistic cox regression was performed to explore predictors of revision. Overall 15-year survivorship was 89.9%. Female survivorship of 88.1% was statistically worse than the male group at 91.8% (p=0.018). Younger patients (75yrs of age (p= 0.036). There was a large range in surgical case load by individual surgeons (range 17–570 knees). There were no statistically significant differences in age, BMI, or gender when comparing the individual surgeon groups. There was a large range in 15-year survivorship between individual surgeons (range 78.3% – 95%). Overall the most common reason for revision was due to wear of the unreplaced portion of the knee (lateral and/or patella-femoral joint) followed by aseptic loosening, polyethylene dislocation, infection or
The pain of arthritic disorders occurs in a social and environmental context. Thus, the pain of arthritis not only can affect the patient, but also the spouse. Numerous investigations have shown that the spouses of individuals with
Essex-Lopresti injuries are often unrecognized acutely with resulting debilitating adverse effects. Persistent axial forearm instability may affect load transmission at both the elbow and wrist, resulting in significant pain. In the setting of both acute and chronic injuries metallic radial head arthroplasty has been advocated, however there is little information regarding their outcome. The purpose of this study was to assess the efficacy of a radial head arthroplasty to address both acute and chronic Essex-Lopresti type injuries. A retrospective review from 2006 to 2016 identified 11 Essex-Lopresti type injuries at a mean follow-up of 18 months. Five were diagnosed and treated acutely at a mean of 11 days (range, 8 to 19 days) from injury, while 6 were treated in a delayed fashion at a mean of 1.9 years (range, 2.7 months to 6.2 years) from injury with a mean 1.5 (range, 0 to 4) prior procedures. The cohort included 10 males with a mean age was 44.5 years (range, 28 to 71 years). A smooth stem, modular radial head arthroplasty was used in all cases. Outcomes included range of motion and radiographic findings such as ulnar variance, capitellar erosion, implant positioning and implant lucency using a modification of the method described by Gruen. Reoperations, including the need for ulnar shortening osteotomy, were also recorded. Three patients in each group (55%) reported
Chronic massive irreparable rotator cuff tears represent a treatment challenge and the optimal surgical technique remains controversial. Superior capsular reconstruction (SCR) has been proposed as a means to provide superior stability to the glenohumeral joint, thus facilitating restoration of shoulder function. However, despite the growing use of SCR there is a paucity of data evaluating the outcomes when performed using a dermal allograft. The purpose of this study was to (1) report the overall survival rate (reoperation and clinical failure) of SCR (2) evaluate for pre-operative factors predicting reoperation and clinical failure. From January 1, 2015 to November 31, 2017, 65 patients were diagnosed with irreparable rotator cuff tears and consented for a superior capsular reconstruction. These surgeries were performed by 6 surgeons, all fellowship trained in either sports or shoulder and elbow fellowships. Outcomes were graded as excellent, satisfactory, or unsatisfactory using the modified Neer scale. An unsatisfactory result was defined as a clinical “failure”. The Kaplan-Meier survival models were created to analyze reoperation-free and failure-free survival for the entire group. The reconstruction was performed using a dermal allograft. There were 31 patients excluded due to insufficient follow-up (< 6 months), leaving 34 included in this study. The mean follow-up was 12 months (range, 6–23). The average number of prior surgeries was 0.91 (range, 0–5), with 52.9% of patients receiving a prior rotator cuff repair and 38.2% of patients with a prior non-rotator cuff arthroscopy procedure. The one and two-year survival-free of surgery was 64% and 44% and the one and two-year survival free of failure was 34% and 16% following SCR, respectively. For the patients that underwent a reoperation, 62.5% (n= 5/8) underwent reverse shoulder replacements, 25% (n= 2/8) latissimus dorsi tendon transfers, and 12.5% (n= 1/8) a diagnostic arthroscopy. The average period between the primary and revision surgery was 10.2 months (range, 2.1–18.5). All but two patients (75%, n= 6/8) had at least one surgery prior to the SCR. There were 14/34 (41.2%) patients who experienced pain, weakness, and restricted range of motion. These patients were defined as clinical failures with an unsatisfactory grading on Neer's criteria. Previous surgery predicted reoperation (80% vs 43%, p = 0.03). Female gender predicted clinical failure (100% vs 43%, p < 0 .01). Superior Capsule Reconstruction performed for large to massive rotator cuff tears has a high rate of
Introduction. Tibial component malrotation is one of the commonest causes of pain and stiffness following total knee arthroplasties, however, the assessment of tibial component malrotation on imaging is not a clear-cut. Aim. The objective of this study was to assess tibial component rotation in cases with pain following total knee replacement using MRI with metal artifact reduction technique. Methods. In 35 consecutive patients presented to our clinic between January 2016 and April 2017 with persistent unexplained moderate to severe pain for at least 6 months following total knee arthroplasties after exclusion of infection, MRI evaluation of tibial component rotation using O-MAR technique-(Metal Artifact Reduction for Orthopedic implants) to improve visualization of soft tissue and bone by reducing artifacts caused by metal implants- was done according to the technique of Berger et al. Results. 25 cases showed internal rotation of tibial component, 5 cases showed neutral rotation, 5 cases showed external rotation with presence of abnormal intraarticular fibrous bands. Conclusion. Two main conclusions are obtained from this study:. Firstly: Internal rotation of tibial component must be excluded in all cases of
Introduction. Adverse reaction to metal debris (ARMD) is an increasingly recognised complication of metal-on-metal hip arthroplasty. A previous study described poor results following revision and recommended early intervention. 1. We determined the outcome of revision for ARMD and present the largest case series to date. Methods. Between 2005 and 2010, 98 patients (101 hips) underwent revision for ARMD. The diagnosis of ARMD was based on clinical history, examination, appearance at revision and histology. Patients were reviewed at 3, 6 and 12 months and annually thereafter. Patient satisfaction, Harris hip scores (HHS) and metal ions were analysed. Results. 54 patients (55 hips) with an average age of 58 years (29 to 81 years) completed minimum one year follow-up (range 1 to 5 years). The mean HHS improved from 49.7 (10 to 79) to 86.3 (40 to 100). Forty-five (81%) patients were satisfied and nine (16%) patients were not satisfied with the outcome. The mean serum cobalt 24.5 (1.65 to 96.6) improved to 1.17 (0.31 to 6.99). Two patients died from unrelated diseases. There were 8 (14%) dislocations and one (1.8%) sciatic nerve palsy that has not recovered. Eight (14%) patients needed re-revision (dislocation: 5 and pain: 3). 26 % had severe soft tissue damage. Six patients have
Introduction.
Background. Under- or oversizing of either component of a total knee implant can lead to early component loosening, instability, soft tissue irritation or overstuffing of joint gaps. All of these complications may cause postoperative
Introduction. An important factor in the functional results after total knee arthroplasty (TKA) is the achieved maximal flexion. To date, a TKA still provides dissimilar flexion capabilities compared to the healthy knee, which could be due to the mismatch between the normal knee geometry and the implant geometry. The implant design of the Journey (Smith&Nephew) aims to replicate the normal knee function. According to the manufacturer of the Journey system, it intends to replicate PCL and ACL function, accommodates deep flexion, induces normal tibiofemoral axial rotation and provides proper patellar tracking throughout the entire range of flexion (‘guided motion’). The objective of this study is to investigate the maximal knee flexion one year after surgery of the Journey and its predecessor the Genesis II (Smith&Nephew). In addition, clinical and functional outcomes will be evaluated. Methods. A total of 124 patients presenting with noninflammatory osteoarthritis received the Journey or the Genesis II prosthesis, by randomization. The primary outcome was defined as the maximum flexion angle on a lateral X-ray performed with the patient lying on a bench and using manual force on bending the knee. Secondary outcomes were: active flexion (lying and standing), Knee Society System score (KSS), Patella Scoring System (PSS), number of adverse events (AE) and satisfaction. The changes in KSS and PSS between the pre-operative situation and 1 year after surgery were calculated as: δKSS = KSS. 1 year. – KSS. pre-op. , and δPSS = PSS. 1 year. – PSS. pre-op. Two-sided t-tests and non-parametric alternatives were performed in order to test for differences between the Journey and the Genesis II group. Results. The demographic and flexion characteristics were comparable between the two groups at baseline. No significant differences could be observed in maximal flexion on X-ray as well as the active flexion between both groups at 1 year (Figure). Median maximal flexion on X-ray was 127° (range 83°-150°) in the Journey group and 125° (range 81°-145°) in the Genesis II group. The active flexion was lower (p<0.001) than the flexion on X-ray (both lying and standing, median 120°). The δKSS and δPSS scores improved significantly more for the Genesis II (p=0.018 and p=0.005, respectively). In the Journey group 40 AEs in 27 patients were reported, including 14 manipulations under anaesthesia (MUA), 10 patients with
Hip arthroscopy rates continue to increase. As a result, there is growing interest in capsular management techniques. Without careful preservation and surgical techniques, failure of the repair result in capsular deficiency, contributing to iatrogenic instability and
Despite the successful, durable results, concern remains for using TKA in patients with isolated patello-femoral OA, as it requires an extensive surgical exposure and bone resection, a long recovery time, and a potentially more complex revision than that required for a patient with a failed patello-femoral arthroplasty (PFA). PFA was introduced in the late 1970s. While PFA was successful in providing pain relief, the procedure did not gain widespread use because of initial design limitations that predisposed to PF maltracking, catching, and subluxation. The mechanical complications associated with first-generation PFA offset the potential advantages of maintaining the knee's native soft tissues and spurred efforts to improve implant design, and to refine surgical techniques and patient selection. Over the past two decades, second generation PFAs incorporated changes in implant design and instrumentation and have shown promising results when used in the properly selected patient population. In addition, with improved instrumentation and robotics, adequate implant alignment and rotation can be achieved in the majority of patients, including those with severe patellofemoral dysplasia. Our meta-analysis of TKA and PFA for the treatment of isolated patello-femoral OA showed that the rate of complications of patients undergoing PFA was 30% after a median follow up of 5.3 years, which is significantly higher than the 7% rate of complications in patients who underwent TKA. The most frequent type of complication associated with PFA was mechanical (including loosening and instability), which is consistent with the malalignment and maltracking-related failures previously reported. The incidence of re-operation after PFA (21%) was significantly higher than that seen after TKA (2%). The most frequent indication for re-operation after PFA was mechanical failure (7%), followed by progression of OA (6%), and
