The number of total knee arthroplasties continues to increase annually with over 90,000 total knee replacements performed in the United Kingdom in 2018. Multiple national bodies including the British Association for Surgery of the Knee (BASK) and the British Orthopaedic Association collaborated in July 2019 to produce best practice guidance for knee arthroplasty surgery. This study aims to review practice in a regional healthcare trust against these guidelines. Fifty total knee replacement operation notes were reviewed between January and February 2020 from 11 different consultant orthopaedic surgeons. Documents were assessed against 17 criteria recommended by the BASK guidance. Personnel names and grades were generally well documented. Tourniquet time and pressure were documented in over 98% of operation notes however, protection from spirit burns was not documented at all. Trialling and soft tissue balancing was well recorded in 100% and 96% of operation notes respectively. Areas lacking in documentation included methods utilised to optimise cementation technique and removal of cement debris. Protection of key knee structures was documented in only 56% of operation notes clearly. Prior to closure, final assessment of mechanism integrity, collateral ligament was not documented at all and final ROM after implantation of components was recorded 34% of the time. Subsequently authors have created a universal operation note template, uploaded onto the patient electronic notes, which prompts surgeons to complete documentation of the relevant criteria advocated by BASK. In conclusion, detailed and systematic documentation is vital to prevent adverse events and reduce the risk of litigation. By producing detailed operative templates this risk can be mitigated

The Royal College of Surgeons of England (RCS) Good Surgical Practice guidance identifies essential criteria for surgical operation note documentation. The current quality improvement project aims to identify if using pre-templated operation notes for documenting fractured neck of femur surgery results in improved documentation when compared to free hand orthopaedic operation notes. A total of fourteen categories were identified from the RCS guidance as required across all the operations identified in this study. All operations for the month of October 2021 were identified and the operation notes analysed. Pre-templated operation notes were compared to free hand operation notes. 97 cases were identified, of which 74 were free hand operation notes and 23 were pre-templated fractured neck of femur operation notes. All fourteen categories were completed in 13 (57%) of the templated operation notes vs 0 (0%) in the free hand operation notes (odds ratio 0.0052, 95% CI 0.0003 to 0.0945, p < 0.001). The median total number of completed categories was significantly higher in the templated op-note group compared to the free hand op-note group (templated median 14, range 12-14, vs. free hand median 11, range 9 to 13, p < 0.001). Logistic regression analysis of operation notes written by Registrars or Consultants identified Registrars as more likely to document the antibiotic prophylaxis given (p = 0.025). Use of pre-templated operation notes results in significantly improved documentation. Adoption of generic pre-templated operation notes to improve surgical documentation should be considered across all operations

Abstract. INTRODUCTION. In the NHS the structure of a “regular healthcare team” is no longer the case. The NHS is facing a workforce crisis where cross-covering of ward-based health professionals is at an all-time high, this includes nurses, doctors, therapists, pharmacists and clerks. Comprehensive post-operative care documentation is essential to maintain patient safety, reduce information clarification requests, delays in rehabilitation, treatment, and investigations. The value of complete surgical registry data is emerging, and in the UK this has recently become mandated, but the completeness of post-operative care documentation is not held to the same importance, and at present there is no published standard. This project summarises a 4-stage approach, including 6 audit cycles, >400 reviewed operation notes, over a 5 year period. OBJECTIVE. To deliver a sustainable change in post operative care documentation practices through quality improvement frameworks. METHODS. Stage 1: Characterise the problem and increase engagement through: SMART aims, process mapping, hybrid action-effect and driver diagram and stakeholder analysis. Multi disciplinary stakeholders were involved in achieving a consensus of evidence-based auditable criteria. Stage 2: Baseline audit to assess current practice. Stage 3: Intervention planning by stakeholders. Stage 4: Longitudinal monitoring through run charts and iterative refinement. RESULTS. Stage 1: Process mapping identified numerous downstream effects of the absence of critical information from operation notes, and the action-effect diagram highlighted the multiple unnecessary mitigating actions performed by ward staff. An MDT consensus was achieved on 15 essential criteria for complete documentation, including important negative fields. Interest-influence matrix identified stakeholder groups with high influence but low interest who needed engagement to deliver change. Stage 2: Baseline audit demonstrated unexpectedly poor documentation: >75% compliance in 4 criteria, and <50% compliance in 10 criteria, which elevated the interest of key stakeholders. Stage 3: A post-operative care template based on the 15 criteria was embedded within the existing IT software. It allowed use of existing operative templates, with a non-overwriting suffix requiring only two mouse clicks. Stage 4: Re-audit at 3 and 12 months showed improved and sustained compliance. At 24 months compliance had declined. Questionnaire of template usage identified problems of criteria response options, and lack of awareness of template by newly appointed staff. Template update improved compliance over the next 6 months (>75% compliance in 11 criteria). Finally, a further reaudit conducted 12 months after the template update (5 years post baseline audit) showed a sustained improvement in compliance (>75% compliance in 13 criteria). CONCLUSIONS. Simple innovation through quality improvement frameworks has changed documentation practices by 1) achieving a consensus from stakeholders, 2) a “shock and awe” moment to highlight existing poor documentation and increase engagement 3) implementing change which fit easily into existing systems, 4) respecting autonomy rather than enforcing change and 5) longitudinal monitoring using run charts and an iterative process to ensure the template remains fit for purpose. This model has now successfully been translated to other subspecialities within the orthopaedic department. Declaration of Interest.

Purposes of study. Evaluation of the pre-operative documentation of neurovascular status in children presenting with Gartland Grades 2 and 3 supracondylar fractures and the development of an Emergency Department Proforma. Methods and results. A retrospective case-note review was performed on patients with Gartland Grade 2 and 3 supracondylar fractures observed in a two-year period from July 2008 – July 2010. 137 patients were included; sixteen patients (11.7%) sustained a Gartland Grade 2a fracture, sixty patients (43.8%) a Gartland Grade 2b fracture and sixty-one (44.5%) a Gartland Grade 3 fracture. Mean patient age at presentation was 5.59 years (range 12 months to 13 years). Nineteen patients (13.9%) had evidence of neurological deficit at presentation and thirteen patients (9.5%) presented with an absent radial pulse. Only twelve patients (8.8%) and nineteen patients (13.9%) respectively had a complete pre-operative neurological or vascular assessment documented. Regarding the individual nerves, fifty-nine (43.1%) patients had median nerve integrity documented, fifty-five (40.1%) ulnar nerve and forty-nine (35.8%) radial nerve integrity documented. Only eighteen patients (13.1%) had their anterior interosseous nerve function documented. Ten patients (7.3%) had post-operative neurological dysfunction, consisting of eight ulnar nerve injuries, and two radial nerve injuries. vi) Conclusions. Pre-operative documentation of neurovascular status in children with displaced supracondylar fractures was poor. Documentation of anterior interosseous nerve examination was particularly poor. We propose the introduction of a proforma (Liverpool Upper-limb Fracture Assessment – LUFA) to increase documentation of neurovascular assessment and optimise emergency department evaluation of children presenting with upper limb injuries

Background and Aims. Daily senior review is of paramount importance to provide optimal clinical care and facilitate timely discharge. Also, the General Medical Council state in Good Medical Practice 2013 that “work should be recorded clearly, accurately and legibly…containing relevant clinical findings, decisions made and actions agreed”. This audit aims to evaluate whether all trauma and elective Orthopaedic patients at one unit receive a daily senior review, which is fully documented in the case-notes, and whether a Comprehensive Unit-based Safety Programme (CUSP) toolkit can better facilitate this?. Methods. Case-notes for all patients admitted under Trauma and Orthopaedics on three separate non-consecutive days during a two-week period were scrutinized, examining them for the presence of CUSP toolkits and whether these were adequately completed. Results. 71 case-notes containing 291 CUSP toolkits were analysed. 46.4% had a completed toolkit for everyday since admission; however for those that did not, over half (55.2%) did not have a senior review documented elsewhere for the missing days. Only 1.4% of case-notes had a full complement of up-to-date CUSP toolkits completed entirely correctly. For patients on Orthopaedic wards, most common errors were failure to document date and time (69.7% incorrect), ward and bed number (30.7% incorrect), patient alerts (70.7% incorrect) and overall compliance in documentation of required parameters such as MRSA status, investigations, observation and fluid charts (23% incorrect). Conclusion. In conclusion, better education for clinical staff is needed to improve compliance both with daily senior review, CUSP toolkits and overall documentation to provide optimum patient care

Background. The British Orthopaedic Association Standards for Trauma (BOAST) for peripheral nerve injuries. 1. states:. “A careful examination of the peripheral nervous and vascular systems must be performed and clearly recorded for all injuries. This examination must be repeated and recorded after any manipulation or surgery.”. This study investigated whether this standard was met for patients with upper limb trauma at a busy London Accident and Emergency (A&E) Department. Method. Data was gathered prospectively from A&E admission notes for 30 consecutive patients with upper limb injuries from the week beginning 11. th. March 2013. Eligibilty: All patients with upper limb injuries. Results. 30 patients: 18 Males mean age of 39.2 and 12 Females mean age of 40.1. 17 patients (56.6%) had documentation of examination of neurovascular status. 14 patients required manipulation and/or splinting of their injury. Of these, no patients had their neurovascular examination documented after the procedure. Poor adherence to the standard is evident across all grades of doctors: FY2, SHO and SpR. Conclusion. There is clear scope to improve documentation of neurovascular status in upper limb injuries. It is especially important to clearly document neurovascular status following manipulation or splinting from a medico-legal perspective. This applies to all grades of staff in A&E. Recommendations. 1. Education of A&E staff of all grades at the departmental induction. 2. Posters in A&E with simple treatment algorithm for managing fractures and dislocated joints. 3. Re-audit in 6 months

Introduction. Medical Exposure Directive of the European Commission, 97/43/Euratom recommended setting-up local national diagnostic reference levels (DRLs) for the most common radiological examinations in order to comply with the law and to maintain safe clinical practice. There are no guidelines for spinal diagnostic and therapeutic procedures. The aims of this study were to evaluate local radiation doses & screening times for diagnostic spinal blocks, to look at PACS image intensifier films for diagnostic representation and to assess the accuracy of data in IR(ME) document. Materials and Methods. Between 1/01/2009 and 15/07/2010, all spinal blocks done under care of three spinal surgeons (LB/NC/AAC) were reviewed. Images revisited on PACS for confirmation. We reviewed 229 patients (included single & two levels nerve root blocks, facet joint and lysis blocks). Data were collected with regard to radiation dose, screening times, third-quartile values used to establish DRLs, IR(ME) documentation and PACS fluoroscopic image documentation. Results. Third quartile single level NRB DAP (Dose area product) was 111.5 cGyCm2. Single level NRB screening time was mean-0.13, third quartile-0.2 min. Nerve specific dosimetry included L5 nerve (0.2 min; 119cGyCm2) and S1 nerve (0.2 min; 118.7cGyCm2). Mean ‘Click: Block ratio’ (last click for PACS/Block) was 22.4 (SD=7.05, range 10 to 48). Local fluoroscopic documentation was 87.2%. Conclusions. There are no national standards in radiation dosimetry for diagnostic spinal blocks. We recommend that all spinal units in the UK should evaluate their own DRLs to help establish national guidelines for fluoroscopy-guided spinal procedures. Representative fluoroscopic image documentation on PACS was 87% locally. It is a joint responsibility of radiographer & operating surgeon to make it 100% to reduce medicolegal risks

Background: The interpretation of safety data from clinical studies such as complication risks requires clear definition of targeted and documented complication events. In addition a standardized classification of complications is required to allow appropriate comparison of safety data between studies and treatment groups. This presentation highlights a proposal for a standardized management and classification of complication data to initiate and seek consensus among trauma surgeons active in clinical documentation and research. Methods: Complication events are examined regarding their timing of occurrence as well as their potential causal inter-relationship for any given patient. While independent events are numbered sequentially, directly associated events (e.g. a fracture collapse and implant screw perforation into a joint) receives the same complication number. Complications are described and categorized according to a pre-defined list of anticipated complication types, or as un-anticipated complications. They are further classified as local or general; local complications occur at or directly around the injuries and are further classified as being “Implant/Surgical procedure”, “Bone/Fracture” or “Soft tissue/Wound” events. Information regarding their operative and/or non-operative treatment and their outcome is recorded. Further assessments are made regarding their seriousness, their relation to the implant used. Final classification of complication events is better determined after independent review by a panel of experienced clinicians. Results: Our classification process was applied successfully to a series of clinical studies at our department. In a study of 185 distal radius fractures treated by LCP, at least one complication occurred in 21 patients, and in seven cases there was a combination of associated events (e.g. one CTS with tendon rupture). Complication risks ranging from 0% to 11.4% were noted depending on which complications and time frames were considered. There was no risk to obtain a LCP implant specific related complication, whereas the risk for a local complication within 6 months after surgery was 6% (95% CI: 3% – 11%). Conclusions: This management and classification system proved valuable in the documentation and analysis of safety data from clinical studies. It facilitates communication and understanding of definitions between clinicians, as well as allows a prompt, standardised and accurate analysis and reporting of complication events and risks. We encourage other clinical researchers and professionals to participate in the further development and acceptance of a universal classification system for complications in traumatology and orthopaedics

Background: The number of total ankle replacements has been raising in the last years. Most publications present short- and medium-term results. Comparison of outcomes is difficult because of inconsistent terminology and different parameters used. Moreover, poorly performing implants cannot be identified quickly because of low numbers, delayed reporting or publication bias. Methods: Therefore, we have developed a module for total ankle prostheses in the framework of the International Documentation and Evaluation System (IDES) for standardized and centralized documentation of TAA outcomes. Content validation was conducted with a single surgeon series of 74 HINTEGRA_ ankle replacements. Results: Between March 2004 and February 2008 74 patients were treated. The preoperative diagnosis was 18.9% osteoarthritis, 32.4% rheumatoid arthritis, 43.3% posttraumatic, 1.4% osteonecrosis and 4% others. There were intraoperative complications in 4%, local postoperative complications in 17.6% and revision surgeries in 16.2% of patients. The AOFAS hind-foot score improved from 23.8 points preoperative to 75.3 points after a mean followup time of 8.4 months. No significant differences in outcome were revealed between the various diagnostic groups. Conclusion: The IDES-forms facilitate a structured and standardized data collection that is feasible in a research orientated but also purely clinical setting; this because of the different extents to which data can be recorded. The consistent use of the system assures a stringent internal quality assurance, and more interesting, an external quality assurance by means of comparisons and benchmarking with other users feeding the data pool with the exact same variables and outcomes. The Hintegra ankle appeared as a safe device with low complication rates in the hands of a foot and ankle specialist. A surgical learning curve was seen in the first two years

The 1995 Audit Commission report, “Setting the Record Straight- A study of hospital medical records,” criticised the poor standard of NHS record keeping. A retrospective audit of documentation of patients undergoing a closed manipulation of distal radius fractures (Colles type) in the Accident and Emergency department of the Queen Alexandra Hospital revealed that note keeping still needs to be improved. Only 15% of patients had adequate documentation

Integrated care pathways (ICPs) have been shown to have many benefits in clinical practice and are being widely adopted in orthopaedic surgery. A high standard of medical record keeping is important for safe patient care and provides information for research, audit and medico-legal purposes. This study compares the quality of medical notation in an ICP with traditional record keeping. During a 3 month period 53 total hip replacements (ICP notation) and 30 total knee replacements (traditional notation) were performed in our unit. The records of each patient were scrutinised using a standardised scoring system, based on The Royal College of Surgeons’ guidelines on medical record keeping. Each set of records (83) were scored for admission clerking, subsequent entries, consent form, operation note and discharge letters. The time taken to retrieve this information was also recorded. The overall score for traditional records (mean 70%) was significantly higher than for the ICP records (mean 62%), p=0.001. The mean scores for initial clerking, subsequent entries and consent form were higher in the traditional record group. It took 35% longer to retrieve information from the ICP group (p < 0.001). In this study the quality of record keeping was higher when using the traditional notation than an established Integrated Care Pathway. In both groups the standard of clinical documentation was disappointing and must be improved if the potential clinical advantages of ICPs are to be realised. Better education of junior staff and regular auditing of medical records could improve this

This paper will focus on the use and including a demonstration of Digital photography for the purpose of clinical documentation, audit, teaching and research. Digital photography is particularly suitable in upper & lower limb surgery because of the discrete regional anatomy and radiology. Digital images once created and stored do not deteriorate, unlike pictures or slides. Digital camera that uses a single floppy disc has an added advantage of simplicity and ease of storage. Pre-op, intra-op, and post-op images of patients undergoing hand surgery and treatment are easily documented with the camera. The information can be archived using commercially available filing software such as File MakerPro. The information can be retrieved at a later stage to be used in audit, teaching and research, with the images retained in their original, unmodified condition. Existing clinical, historical and teaching library slides, pictures or images can be archived to ensure the quality of the images do not deteriorate further, and for ease of retrieval and subsequent application. Archiving in this manner would require a slide scanner. The ease of file retrieval, reliability and accuracy of this imaging system has been tested using a minimum of 2000 patient files, using both PC and Macintosh systems, with no computer error and minimal operator errors found. The software used has “auto save” feature built in, hence computer “crash resistance.” The only limitation of the technology is the set up costs, and the resolution of the images. Fortunately, both these limitations are improving rapidly

One of the ethical and legal requirements of valid consent for treatment is that patients must be fully informed about the complications involved. The General Medical Council (UK) insists that all adverse outcomes of a treatment, which are serious or frequently occurring, must be discussed with the patient.

Previous studies have found a large variance in the risks documented on consent forms for orthopaedic hip operations. The aim of this study was to compare the risks documented for three orthopaedic hip operations against pre-constructed operation-specific consent forms endorsed by the British Orthopaedic Association.

We retrospectively analysed 300 consent forms for total hip replacements, hip hemiarthoplasties and dynamic hip screw operations (n=100 for each) and noted the risks documented, whether the form was completely legible, the grade of the Doctor obtaining consent and whether a copy of the consent form was given to the patient.

We found that of the 300 operations, only 43.1% of the complications were documented as recommended by the British Orthopaedic Association. Furthermore, 26.3 % of consent forms were illegible, 72.7% of patients were consented by the Senior House Officer and only 13.7% of patients were offered a copy of the consent form.

Our results indicate that the Methods: of obtaining consent and filling in the consent forms for orthopaedic hip operations could be vastly improved. One method which could be utilized to achieve this would be the incorporation of procedure specific templates in the consenting process. These templates are already in the public domain and free to use at www.orthoconsent.com. This would allow the patient to weigh up the risks and make a valid informed decision about their treatment and also protect the Doctors from any possible litigation.

Tourniquet is a commonly used tool in orthopaedic practice. Incidence of complications is low but if any develops, it is devastating. Transient nerve damage, ischemia or skin burns are the possible tourniquet related complications. There is big variation in practice regarding the limb occlusion pressure. 51 procedures in 50 patients were reviewed retrospectively in our district general hospital. We looked at quality of documentation guided by the BOAST standard (The Safe Use of Intraoperative Tourniquets, published in October 2021). Limb occlusion pressure and ischemic time were analysed. Intra-operative and post-operative notes were reviewed to assess quality of documentation and post-operative complications. Although limb occlusion pressure was above the recommended range in more than 75% of cases, there were no significant complications observed. Two cases only developed transient neuropraxia in common peroneal nerve and median nerve following tibial plateau ORIF and trapeziectomy simultaneously. Tibial ORIF fixation case had prolonged ischemic time (more than 120 minutes) and the limb occlusion pressure for the hand case was above the recommended range. Both have recovered within few days with no long-term consequences. Minimum documentation threshold was not met with regarding tourniquet site condition, method of skin isolation and padding, and exsanguination method. This relatively new standard with no previous similar guidance needs time until it is followed by the health care professionals especially when there is no high incidence of complications related to the use of the tourniquet. However, it is crucial to increase the theatre staff awareness of such standards. This will prevent devastating complications specifically in vulnerable patients. Adjustments to theatre checklist have been suggested to improved documentation. Additionally, local teaching sessions will be delivered to theatre personnel aiming at improving our compliance to this standard

The purpose of this study was (1) to evaluate the adequacy of informed consent documentation in the trauma setting for distal radius fracture surgery compared with the elective setting for total knee arthroplasty (TKA) at a large public hospital and (2) to explore the relevant guidelines in New Zealand relating to consent documentation. Consecutive adult patients (≥16 years) undergoing operations for distal radius fractures and elective TKA over a 12-month period in a single-centre were retrospectively identified. All medical records were reviewed for the risks and complications recorded. The consent form was analysed using the Flesch Reading Ease Score (FRES) and the Simple Measure of Gobbledygook (SMOG) index readability scores. A total of 133 patients undergoing 134 operations for 135 distal radius fractures and 239 patients undergoing 247 TKA were included. Specific risks of surgery were recorded significantly less frequently for distal radius fractures than TKA (43.3% versus 78.5%, P < 0.001). Significantly fewer risks were recorded in the trauma setting compared to the elective (2.35 ± 2.98 versus 4.95 ± 3.33, P < 0.001). The readability of the consent form was 40.5 using the FRES and 10.9 using the SMOG index, indicating a university undergraduate level of reading. This study has shown poor compliance in documenting risks of surgery during the informed consent process in an acute trauma setting compared to elective arthroplasty. Institutions must prioritise improving documentation of informed consent for orthopaedic trauma patients to ensure a patient-centred approach to healthcare

Trauma, across the United Kingdom, is managed using several software, paper based lists on Microsoft Word/Excel or Teams. There is usually poor handover or no handover in a standard format- during the on call, in the trauma meetings or in the wards. The software in the market for trauma management are not cost friendly or adaptable to local demands. The alternatives like Microsoft WORD based lists are fraught with their own problems. We endeavoured to make our trauma management effective. A Quality Improvement Project was done. The goals to achieve at end of a year were:. Daily Trauma Handover in standardised format >90%. Ward Handover in standardised format >90%. Availability of outcomes of patients in clinic >80%. Reduction of paper usage >90% at the end of six months. Availability of updated “outliers” information >90% at the weekend ward round. Documentation from the Trauma Meeting > 90%. On-Call documentation in standardised format >90%. Doctor Satisfaction >75% in terms of: ease of us;, searchability of patient; ward round experience; morning trauma meeting experience; handover experience; inter-specialty communication; reliability; daily time saving; on-call time saving; patient care/safety; overall satisfaction. We used Microsoft Sharepoint List to manage our trauma workload and have named the tool as “The List”. The List has achieved all objectives as above in one year's time, except Outlier information which was at 67% in a recent PDSA (Plan-Do-Study-Act) cycle. The survey showed excellent doctor satisfaction and 90% respondents felt that The List saved an hour or more during the on-call and also during the ward rounds. We conclude that The List is a very powerful tool making trauma meetings efficient and handover effective. It is indigenous, adaptable, safe, sustainable, cost neutral and easy to use

Introduction. Compartment syndrome can be a life changing consequence of injury to a limb. If not diagnosed and treated early it can lead to permanent disability. Neurovascular observations done on the ward by nursing staff, are often our early warning system to those developing compartment syndrome. But are these adequate for detecting the early signs of compartment syndrome? Our aim was to compare the quality and variability of charts across the UK major trauma network. Materials & Methods. All major trauma centres in England and Scotland were invited to supply a copy of the neurovascular chart routinely used. We assessed how such charts record relevant information. Specific primary data points included were pain scores, analgesia requirements, pain on passive stretch and decreased sensation in the first web space specifically. As secondary objectives, we assessed how late signs were recorded, whether clear instructions were included, quantitative scores and the use of regional blocks recorded. Results. A response rate of 46% was achieved. Of the charts reviewed, 25% documented pain scores or pain on passive movement. Pain on movement and analgesia requirements were documented in 33% and 8% respectively. Specific sensation within the 1. st. webspace was recorded in 16%. No charts recorded use of regional block. All charts recorded global sensation, movement (unspecified), pulse and colour whilst 66% documented capillary refill and 83% temperature. Instructions were included in 41% of charts. Conclusions. In 2016, the BOA supported publication of an observation chart for this purpose however, it is not widely used. In our study, late signs of compartment syndrome were generally well recorded. However, documentation of early signs and regional blocks was poor. This may lead to delays in diagnosis with significant clinical and medicolegal consequences. Standardisation of documentation by updating and promoting the use of the pre-existing chart would ensure highest quality care across the network

Aims. The Oswestry-Bristol Classification (OBC) is an MRI-specific assessment tool to grade trochlear dysplasia. The aim of this study is to validate clinically the OBC by demonstrating its use in selecting treatments that are safe and effective. Methods. The OBC and the patellotrochlear index were used as part of the Oswestry Patellotrochlear Algorithm (OPTA) to guide the surgical treatment of patients with patellar instability. Patients were assigned to one of four treatment groups: medial patellofemoral ligament reconstruction (MPFLr); MPFLr + tibial tubercle distalization (TTD); trochleoplasty; or trochleoplasty + TTD. A prospective analysis of a longitudinal patellofemoral database was performed. Between 2012 and 2018, 202 patients (233 knees) with a mean age of 24.2 years (SD 8.1), with recurrent patellar instability were treated by two fellowship-trained consultant sports/knee surgeons at The Robert Jones and Agnes Hunt Orthopaedic Hospital. Clinical efficacy of each treatment group was assessed by Kujala, International Knee Documentation Committee (IKDC), and EuroQol five-dimension questionnaire (EQ-5D) scores at baseline, and up to 60 months postoperatively. Their safety was assessed by complication rate and requirement for further surgery. The pattern of clinical outcome over time was analyzed using mixed regression modelling. Results. In all, 135 knees (mean age 24.9 years (SD 9.4)) were treated using a MPFLr. Ten knees (7.4%) required additional surgery. A total of 50 knees (mean age 24.4 years (SD 6.3)) were treated using MPFLr + TTD. Ten (20%) required additional surgery. A total of 20 knees (mean age 19.5 years (SD 3.0)) were treated using trochleoplasty + TTD. Three patients (15%) required additional surgery. In each treatment group, there was a significant improvement in Kujala, IKDC, and EQ-5D at one year postoperatively (p < 0.001) with a recognized level of overall complication rate. Conclusion. The OBC is a valid assessment tool to grade patients with trochlear dysplasia and, when used as part of the OPTA, helps to determine treatments that are safe and effective. This fulfils the requirements for its application in mainstream clinical practice. Cite this article: Bone Joint J 2021;103-B(10):1586–1594

Aims. The aim of this retrospective study was to determine if there are differences in short-term clinical outcomes among four different types of matrix-associated autologous chondrocyte transplantation (MACT). Methods. A total of 88 patients (mean age 34 years (SD 10.03), mean BMI 25 kg/m. 2. (SD 3.51)) with full-thickness chondral lesions of the tibiofemoral joint who underwent MACT were included in this study. Clinical examinations were performed preoperatively and 24 months after transplantation. Clinical outcomes were evaluated using the International Knee Documentation Committee (IKDC) Subjective Knee Form, the Brittberg score, the Tegner Activity Scale, and the visual analogue scale (VAS) for pain. The Kruskal-Wallis test by ranks was used to compare the clinical scores of the different transplant types. Results. The mean defect size of the tibiofemoral joint compartment was 4.28 cm. 2. (SD 1.70). In total, 11 patients (12.6%) underwent transplantation with Chondro-Gide (matrix-associated autologous chondrocyte implantation (MACI)), 40 patients (46.0%) with Hyalograft C (HYAFF), 21 patients (24.1%) with Cartilage Regeneration System (CaReS), and 15 patients (17.2%) with NOVOCART 3D. The mean IKDC Subjective Knee Form score improved from 35.71 (SD 6.44) preoperatively to 75.26 (SD 18.36) after 24 months postoperatively in the Hyalograft group, from 35.94 (SD 10.29) to 71.57 (SD 16.31) in the Chondro-Gide (MACI) group, from 37.06 (SD 5.42) to 71.49 (SD 6.76) in the NOVOCART 3D group, and from 45.05 (SD 15.83) to 70.33 (SD 19.65) in the CaReS group. Similar improvements were observed in the VAS and Brittberg scores. Conclusion. Two years postoperatively, there were no significant differences in terms of outcomes. Our data demonstrated that MACT, regardless of the implants used, resulted in good clinical improvement two years after transplantation for localized tibiofemoral defects.
