Abstract

Background

Distinction between foot and ankle wound healing complications as opposed to infection is crucial for appropriate allocation of antibiotic therapy. Our aim was to evaluate the diagnostic accuracy of white cell count (WCC) and C-reactive protein (CRP) as diagnostic tools for this distinction in the non-diabetic cohort.

Methods

Data were reviewed from a prospectively maintained Infectious Diseases Unit database of 216 patients admitted at Leicester University Hospitals – United Kingdom between July 2014 and February 2020 (68 months). All diabetic patients were excluded. For the infected non-diabetic included patients, we retrospectively retrieved the inflammatory markers (WCCs and CRP) at the time of presentation. Values of CRP 0–10 mg/L and WCC 4.0–11.0 ×109 /L were considered normal.

Gel-based autologous chondrocyte implantation (ACI) over the years have shown encouraging results in repairing the articular cartilage. More recently, the use of cultured mesenchymal stem cells (MSC) has represented a promising treatment option with the potential to differentiate and restore the hyaline cartilage in a more efficient way. This study aims to compare the clinical and radiological outcome obtained in these two groups.

Twenty-eight consecutive symptomatic patients diagnosed with full-thickness cartilage defects were assigned to two treatment groups (16 patients cultured bone marrow-derived MSC and 12 patients with gel-type ACI). The MSC group patients underwent microfracture and bone marrow aspiration in the first stage and injection of cultured MSC into the knee in the second stage. Clinical and radiological results were compared at a minimum follow up of five years

There was excellent clinical outcome noted with no statistically significant difference between the two groups. Both ACI and MSC group showed significant improvement of the KOOS, Lysholm and IKDC scores as compared to their preoperative values and this was maintained at 5 years follow up. The average MOCART score for all lesions was also nearly similar in the two groups. The mean T2* relaxation-times for the repair tissue and native cartilage were 27.8 and 30.6 respectively in the ACI group and 28 and 29.6 respectively in the MSC group.

Use of cultured MSC is less invasive, technically simpler and also avoids the need for a second surgery as compared to an ACI technique. With similar encouraging clinical results seen and the proven ability to restore true hyaline cartilage, cultured MSC represent a favorable treatment option in articular cartilage repair.

Background of study

Total Knee Replacement (TKR) is one of the commonest elective arthroplasty operations. Crepe dressings are used following TKR by most surgeons as it may provide comfort and hemostasis through external pressure however, may reduce early range of motion (ROM). Avoiding crepe dressings after TKR saves operating time, avoids bulky dressings (which may reduce ROM) and allows interventions such as cryotherapy in the early post-operative period. There are no published studies comparing the use of crepe dressing after TKR with an impermeable dressing alone

Materials and Methods

We did a retrospective study, analysing patients who had a TKR with the use of crepe dressings compared with patients who had an impermeable dressing alone. All patients had cruciate retaining PFC Implants through the medial para-patellar approach. We compared ROM (at initial physio contact and on discharge), rate of wound leakage, opioid requirements and duration of inpatient stay.

The shoulder is the least constrained of all joints of the body and is more susceptible to injury including dislocation. The rate of recurrent instability following primary stabilization procedure at 10 years of follow-up ranged from 3.4 to 35 %. We describe the outcomes of 74 patients who underwent knotless arthroscopic anterior stabilisation using 1.5 mm Labral Tape with 2.9mm Pushlock anchors for primary anterior instability.

We performed a retrospective analysis of patients who underwent surgery for post-traumatic recurrent anterior instability for 2 years by a single surgeon. Patients with glenoid bone loss, >25% Hill Sachs lesion, posterior dislocation, paediatric age group and multidirectional instability were excluded from this study. Over 90% of our case mix underwent the procedure under regional block anaesthesia and was discharged on the same day. The surgical technique and post-operative physiotherapy was as per standard protocol. Outcomes were measured at 6 months and 12 months. Of the 74 patients in our study, we lost 5 patients to follow up. Outcomes were measured using the Oxford Shoulder Score apart from clinical assessment including the range of motion.

We noted good to excellent outcomes in 66 cases using the Oxford Instability Scores. All patients achieved almost full range of motion at the end of one year. Our cumulative Oxford Instability Score (OIS) preoperatively was 24.72 and postoperatively was 43.09. The Pearson correlation was .28. The t Critical two-tail was 2.07 observing the difference between the means of the OIS. Complications included recurrent dislocation in 2 patients following re-injury and failure of procedure due to recurrent instability requiring an open bone block procedure in one case. We had no reported failures due to knot slippage or anchor pull-out.

We publish the largest case series using this implant with distinct advantages of combining a small bio absorbable implant with flat braided, and high-strength polyethylene tape to diminish the concern for knot migration and abrasive chondral injury with the potential for earlier rehabilitation and a wider footprint of labral compression with comparative outcomes using standard techniques. Our results demonstrate comparable and superior results to conventional suture knot techniques for labral stabilization.

Introduction

We describe five results of a novel single stage arthroscopic technique for the treatment of articular cartilage defects of the knee. This involves micro drilling and application of Atelo-collagen (Coltrix) and fibrin gel scaffold.

Materials and Method

The preclinical study involved two groups of rabbits treated with micro-drilling, and micro-drilling with Atelo-collagen and fibrin gel. New cartilage was subjected to staining with H&E for tissue morphology, toluidine blue (collagen) and safranin O (GAG), immunohistochemistry with antibodies for collagen type I and II, and scanning and transmission electron microscopy to analyse the microstructural morphologies. The micro-drilling with Atelo-collagen, fibrin gel scored better than the micro-drilling alone.

Patients (n=30) with symptomatic ICRS grade III/IV chondral defects (lesion size 2–8cm2) are recruited for this prospective study. The surgical procedure involved micro-drilling and application of Atelo–collagen and fibrin gel under CO2 insufflation. Patients underwent morphological evaluation with MRI (T2*-mapping and d-GEMRIC scans). Clinical assessment was done with Lysholm, IKDC and KOOS scores. Radiological assessment was performed with MOCART score.

Background

Revision surgery for a failed metal on metal (MoM) hip arthroplasty is often unpredictable and challenging due to associated massive soft tissue and bony lesions. We present the analysis and early outcomes of revision surgery in failed MoM hip arthroplasties at our institution.

Methods

We have retrospectively analysed the findings and outcomes of revision surgery in 61 failed MoM hip arthroplasties performed between 2009 and 2014. These patients were identified in the special MoM hip surveillance pathway. All these patients underwent clinical assessment and relevant investigations. Intra-operative and histopathological findings were analysed.

Background

Two-stage revision is considered the gold standard for treatment of knee prosthetic joint infections. Current guidelines for selecting the most appropriate procedure to eradicate knee prosthetic joint infections are based upon the duration of symptoms, the condition of the implant and soft tissue evaluated during surgery and the infecting organism. A more robust tool to identify candidates for two-stage revision and who are at high risk for treatment failure might improve preoperative risk assessment and increase a surgeon's index of suspicion, resulting in closer monitoring, optimization of risk factors for failure and more aggressive management of those patients who are predicted to fail.

Methods

Charts from 3,809 revision total joint arthroplasties were reviewed. Demographic data, clinical data and disease follow-up on 314 patients with infected total knee arthroplasty treated with two-stage revision were collected. Univariate analyses were performed to determine which variables were independently associated with failure of the procedure to eradicate the prosthetic joint infections. Cox regression was used to construct a model predicting the probability of treatment failure and the results were used to generate a nomogram which was internally validated using bootstrapping.

Purpose of the study

We conducted a study to assess the accuracy of Spatial CAD software in computing the mounting and deformity parameters.

Methods and end results

We mounted a two-ring construct on a sawbone tibia and accurately measured the mounting parameters of this frame. Then we obtained three sets of x-rays – orthogonal without magnification marker, orthogonal with magnification marker placed at the level of the bone and non orthogonal views – and put these images through software and obtained mounting and deformity parameters.

Results were independently assessed and we found that the Spatial CAD™ software was accurate within 1 mm and 1 degree when orthogonal images with marker sphere placed at the bone level were used. Non-orthogonal images, with marker sphere, yielded accurate axial frame offset but other mounting parameters were at least 6 mm more than the actual measurements. Understandably angular measurements were different. In the third set of films we used frame hardware – Rancho Cube width (12 mm) as a calibrator. Since the cube was not in the same plane as the bone all measurements were way off actual measurements.

Introduction

The ideal method of fixation for femoral components in total hip arthroplasty (THA) is unknown. While good results have been reported for cemented and uncemented components, there is relatively little published prospective data with twenty years or more of follow up.

Results of the Furlong femoral component have been presented at an average of 17 years follow up. We have extended this follow up period to an average of 22.5 years with a minimum of 22 years and a maximum of 25 years.

Methods

This study included all patients treated using the Furlong femoral component between 1986 and 1991. Patients were reviewed preoperatively and then at 6, 12, 26 and 52 weeks post operatively and annually thereafter.

They were assessed clinically and radiographically and the Merle d'Aubigne Postel hip score was calculated at each visit. A Visual Analog Score (VAS) was also recorded to assess patient satisfaction with their procedure. A Kaplan Meier survival analysis was performed.
