Covid-19 and orthopaedic trauma: Quantification of orthopaedic trauma workload and staff resource allocation during a global pandemic-related lockdown.

Introduction: Healthcare systems across the world have struggled as a result of the Covid-19 pandemic. Most specialties have redeployed their staff and resources to deal with the pandemic whilst ceasing their planned elective activity. However acute specialties such as Trauma and Orthopaedics still have a significant emergency caseload that must be safely managed, even in a pandemic. The aim of this study was to investigate the change in Orthopaedic Trauma caseload in a Trauma Unit and a Major Trauma Centre during a pandemic compared to pre-pandemic levels and the associated staffing requirements. Methods: The data presented was collected from a Trauma Unit and a Major Trauma Centre in the United Kingdom. We compared the number of accident and emergency referrals, fracture clinic appointments, inpatient admissions and operations during the six weeks of the first lockdown from 23rd March to May 3, 2020, to the same time period in 2019. Results: The results showed that the orthopaedic trauma caseload was approximately half that of pre-pandemic levels, reducing by an average of 54.2%. Conclusion: A significant orthopaedic trauma caseload still remains to be safely managed during a pandemic and appropriate resources must be allocated. Staff allocation must take into account sick cover and staff wellbeing. A proportion of staff may need to be ring fenced from redeployment to facilitate this.

Patellofemoral joint degeneration: A review of current management.

The patellofemoral component of the knee joint is affected by a wide range of degenerative causes without involving the other parts of the knee. It is often the presenting pathology in early knee osteoarthritis and missed due to a variable presentation. Accurate examination and focused investigation can help with early diagnosis and guide treatment. Various aspects to treatment need to be addressed after thorough evaluation. Guidelines to approach the multifactorial pathology of the patello-femoral joint are provided with focus on the degenerative component of disease.

Autologous collagen induced chondrogenesis (ACIC: Shetty-Kim technique) - A matrix based acellular single stage arthroscopic cartilage repair technique.

The defects of articular cartilage in the knee joint are a common degenerative disease and currently there are several established techniques to treat this problem, each with their own advantages and shortcomings. Autologous chondrocyte implantation is the current gold standard but the technique is expensive, time-consuming and most versions require two stage procedures and an arthrotomy. Autologous collagen induced chondrogenesis (ACIC) is a single-stage arthroscopic procedure and we developed. This method uses microfracture technique with atelocollagen mixed with fibrin gel to treat articular cartilage defects. We introduce this ACIC techniques and its scientific background.

Repair tissue quality after arthroscopic autologous collagen-induced chondrogenesis (ACIC) assessed via T2* mapping.

OBJECTIVE: A novel single-stage approach using arthroscopic microdrilling and atelocollagen/fibrin-gel application is employed for cartilage repair of the knee. The purpose of our study was to investigate the morphological and biochemical MRI outcome after this technique. MATERIALS AND METHODS: A retrospective case series of ten patients (mean age 45 years) with symptomatic chondral defects in the knee who were treated arthroscopically with microdrilling and atelocollagen application was analyzed. All defects were ICRS grade III or IV and the sizes were 2-8 cm(2) intra-operatively. All patients underwent morphological MRI and T2-star mapping at 1.5 T at 1-year follow-up. The magnetic resonance observation of cartilage repair tissue (MOCART) score was assessed. T2* relaxation time values of repair tissue and a healthy native cartilage area was assessed by means of region of interest analysis on the T2* maps. RESULTS: The mean MOCART score at 1-year follow-up was 71.7 ± 21.0 ranging from 25 to 95. The mean T2* relaxation times were 30.6 ± 11.3 ms and 28.8 ± 6.8 ms for the repair tissue and surrounding native cartilage, respectively. The T2* ratio between the repair tissue and native cartilage was 105% ± 30%, indicating repair tissue properties similar to native cartilage. CONCLUSIONS: An arthroscopic single-stage procedure using microdrilling in combination with atelocollagen gel and fibrin-glue can provide satisfactory MRI results at 1-year follow-up, with good cartilage defect filling. The T2* values in the repair tissue achieved similar values compared to normal hyaline cartilage.

Use of bone graft substitute in the treatment for distal radius fractures in elderly.

INTRODUCTION: Fractures of the distal radius in elderly patients are often associated with metaphyseal defects that can lead to collapse, malunion and therefore decreased function. An alternative approach to simple reduction is to fill the defects with materials that can provide structural support. METHODS: We used synthetic hydroxyapatite (HA) in unstable fractures of the distal radius in thirty-one elderly patients, of which four patients lost to follow-up, leaving twenty-seven patients for this study. All subjects underwent closed reduction with K-wire fixation and HA augmentation. They were followed up at 8- and 16-week intervals post-operatively to assess the functional outcome using patient-related wrist evaluation [PRWE], clinical outcome and radiological outcome. RESULTS: At mean 16 weeks, our results show that patients treated with this method showed no metaphyseal defect, no collapse and had satisfactory clinical outcome as assessed by PRWE. CONCLUSION: We believe that fixation with hydroxyapatite augmentation for fractures of the distal radius in elderly patients is an attractive therapeutic option. This experience has changed our clinical practice.

The "Shetty test" in ankle injuries: validation of a novel test to rule out ankle fractures.

Ankle sprains are by far the commonest ankle injuries. The traditional clinical approach, to any ankle injury, is a clinical examination followed by radiological examination. We have developed a simple clinical test to rule out fractures in ankle injuries and thereby eliminating the necessity for radiological examination. Our test is simple, reproducible, economic, time saving and avoids potential radiation exposure risks.

Hip impingement in the Indian population: hip anthropometry measurements in 100 hips.

We studied 100 hip joints in Indian patients to measure femoral head sphericity, head-neck offset and alpha angle. Our study indicates that the mean values of the above measurements are far below the "danger" level for the onset of femoro-acetabular impingement. It remains to be seen whether these findings explain the low incidence of primary hip osteoarthritis in the Indian population.
