Acute kidney injury (AKI) is a common post-operative complication which, in turn, significantly increases risk of other post-operative complications and mortality. This quality improvement project (QIP) aimed to evaluate and implement measures to decrease the incidence of AKI in post-operative Trauma and Orthopaedics (T&O) patients. Three data collection cycles were conducted using all T&O patients admitted to a single UK West Midlands NHS trust across three six-month periods between December 2018 and December 2020 (n=8215). Patients developing a post-operative AKI were identified using the Acute Kidney Injury Network criteria. Data was collected for these patients including demographic details and AKI risk factors such as ASA grade, hypovolaemia and use of nephrotoxic medications.Abstract
Introduction
Methods
The anterolateral ligament (ALL) is considered as an important stabilizer of the knee joint. This ligament prevents anterolateral subluxation of the proximal tibia on the femur when the knee is flexed and internally rotated. Injury of the ALL was not investigated in patients with knee dislocation. The aim of the current research is to study the prevalence and characteristics of ALL injury in dislocated knees. A retrospective review of charts and radiological images was done for patients who underwent multiligamentous knee reconstruction surgery for knee dislocation in our institution from May 2008 to December 2016. Magnetic resonance imaging (MRI) was used to describe the ALL injury. The association of ALL injury with other variables related to the injury and the patient's background features was examined. Forty-eight patients (49 knees) were included. The mean age of the patients was 32.3 ± 10.6 years. High energy trauma was the mechanism of dislocation in 28 (57.1%) knees. Thirty-one knees (63.3%) were classified as knee dislocation (KD) type IV. Forty-five (91.8%) knees had a complete ALL injury and three (6.1%) knees had incomplete ALL injury. Forty (81.6%) knees had a complete ALL injury at the proximal fibres of the ALL, while 23 (46.9%) knees had complete distal ALL injury. None of the 46 (93.9%) knees with lateral collateral ligament (LCL) injury had normal proximal ALL fibres (p = 0.012). Injury to the distal fibres of the ALL, as well as overall ALL injury, were not associated with any other variables (p >0.05). Moreover, all patients with associated tibial plateau fractures (9, 18.4%) had abnormality of the proximal fibres of the ALL (p = 0.033). High grade ALL injury is highly prevalent among dislocated knees. The outcomes of reconstructing the ALL in multiligamentous knee reconstruction surgery should be investigated in future studies.
The decision to resurface the patella during total knee arthroplasty remains controversial. Aim of our study was to evaluate the functional difference between patients undergoing medial rotation knee (MRK) replacement with and without patellar resurfacing at our hospital. We did a retrospective analysis of patients undergoing MRK total knee replacement (Matortho) at our hospital between 2008 and 2017 performed by 2 surgeons. Patients were recalled for a clinical review from Oct 2017 for recording of Oxford knee, Baldini and Ferrel scores. Mann-Whitney U test was used for non-parametric data (SPSS v24).Background
Methods
This study aimed to evaluate the impact on length of hospital stay from dedicated infectious diseases input for orthopaedic infection patients compared to sporadic infection specialist input. We conducted an observational cohort study of 157 adults with orthopaedic infections at a teaching hospital in the UK. The orthopaedic infections included were: osteomyelitis, septic arthritis, infected metalwork and prosthetic joint infections, and adults were aged 18 years or more. Prior to August 2016, advice on orthopaedic infection patients was adhoc with input principally from the on-call infectious diseases registrar and phone calls to microbiology whereas after August 2016 these patients received regular input from dedicated infectious diseases doctor(s). The dedicated input involved bedside reviews, medical management, correct antimicrobial prescribing, managing adverse drug reactions, increased use of outpatient parenteral antimicrobial therapy (OPAT) services especially self-administration of intravenous antibiotics and shared decision-making for treatment failure, whilst remaining under orthopaedic team care. Orthopaedic patients operated on for management of their infection between 29/8/16 and 15/3/17 were prospectively identified and orthopaedic operation records were used to retrospectively identified patients between 29/8/15 and 15/3/16. The length of stay was compared between the 2 groups.Aim
Method
Objective was to assess clinical results of treatment of Infected Non Union (INU) of long bones, using Antibiotic Cement Impregnated Nail (ACIN), a single or two staged approach, Stage 1 - Debridement, eradication of infection, primary stabilization with (ACIN). 2nd Stage - Definitive stabilization and early rehabilitation. 185 cases of infected non-union of long bones from Jan 2002 to Jan 2009 were treated in this hospital. 46 females and 139 males, age varied from 17–65 years (Avg. 40). Tibia was the commonest bone to be affected, followed by femur & humerus. The control of infection was by debridement, antibiotic cement impregnated K-nail (ACIN) insertion with or without Ilizarov ring fixator application, second stage treatment by definitive internal fixation and bone grafting was done if required. Average duration of follow up, was 26 months (14–58 months). Main outcome measurements were assessment of bone healing, functional outcome, healing time and complications.Introduction
Methods
We performed an advancement and medial transfer of the tibial tuberosity based on Fulkerson's principle to treat intractable anterior knee pain associated with patellofemoral maltracking diagnosed by dynamic MRI. Between January 1998 and July 2000 twenty-two patients had 28 knees operated for anterior knee pain. There were 4 men and 18 women with a mean age of 28 years (range 18-41). Indications for surgery were [a] failure to improve after six months of physiotherapy and [b] patellofemoral maltracking evident in dynamic MRI. Mean follow-up was for 37 months (23 – 42). Knee instability score modified by Fulkerson was employed for objective and subjective assessment. Objectively 22 (79%) knees achieved good to excellent results. Four knees (14%) had fair, and two (7%) had poor results. Excellent and very good results were seen in 20 knees. These patients were a younger age group (mean age 21 years) and had minimal degeneration (grade I-II) of the patellofemoral joints. Two patients achieved good results. One of them had moderate (grade III) and one minimal (II) arthritis. Three knees with fair results had advanced (grade IV or V) and one had moderate (grade III) arthritis. Out of two patients who had a poor result, one had advanced degeneration (grade V) that later required a patellofemoral joint resurfacing. The other was a 24 year old woman with grade II changes. She was treated by the pain therapy team. Anterior displacement of the tuberosity in the presented study was kept to 5 mm to avoid the possible complications of wound break down. The overall length and depth of the osteotomy was also reduced to minimise risk of fracture and commence early mobilisation. Based on our results there is a strong case of justification for Anteromedialisation of tibial tuberosity using a smaller length of osteotomy and lesser degree of anteriorisation in carefully selected patients with Patellofemoral arthralgia associated with maltracking patella.
