Acute knee clinics are effective in reducing delay to diagnosis following anterior cruciate ligament injury

Background: Delays to diagnosis of anterior cruciate ligament (ACL) injury and specialist consultation continue to place patients at risk of early onset osteoarthritis. Incorporating acute knee clinics within a streamlined accident and emergency (A&E) pathway have shown potential in reducing delay but specific evaluative research is lacking. The aim of this service evaluation was to investigate the effectiveness of an acute knee clinic at one NHS Trust in the United Kingdom (UK), on reducing the delay to diagnosis of ACL injury and specialist consultation compared to a standard A&E pathway. Methods: An uncontrolled before and after design was utilised for this service evaluation. Data were collected from historical electronic patient records over a 1-year period with analysed results compared against previously collected data from the same NHS Trust. Results: 81 records met the criteria for the streamlined A&E pathway and were compared against 50 from the standard A&E pathway. For the streamlined A&E pathway median delay to diagnosis reduced from 97 to 14 days and delay to specialist consultation reduced from 158.5 to 45 days and were of statistical significance. The incorporation of an acute knee clinic was identified as the most influential factor on delay in addition to the location of presentation and mechanism of injury. Conclusions: Introducing an acute knee clinic within a streamlined A&E pathway has a clinically relevant effect on reducing delay to diagnosis and specialist consultation and allows findings to be extrapolated and implemented to all UK based NHS Trust A&E departments.
