Knee injuries in elite professional footballers: the findings of one English Premier League team

British Orthopaedic Association 2012 Annual Congress



Abstract

Introduction

Knee injuries are common amongst footballers. The aim of this study was to establish frequency and variation of knee injuries within one English Premier League (EPL) professional football club over two seasons, to assess number of days missed due to injury, and analyse current treatment regimen for each injury type.

Method

Data was collected prospectively for injuries suffered by players between 2009 and 2011, spanning two EPL seasons at one EPL club. Demographics were recorded along with various factors influencing injury, including playing surface, pitch condition, dominant side, type of injury, ability to continue playing, and mechanism of injury. Time taken for return to play, and treatment received was recorded.

Results

35 injuries occurred that were severe enough to cause players to miss at least one competitive match. The commonest injury was to the medial collateral ligament (MCL) in 34%. Patella tendon injuries were seen in 29%, other injuries included meniscus tears, ACL ruptures, and osteochondral defects. All grade II MCL Injuries received sclerosant injections. 40% of patella tendon injuries were given plasma-rich protein (PRP) injections, and 30% underwent surgery. The mean recovery time following MCL and patella tendon injuries was 44 days and 77 days respectively. 60% of injuries were sustained during training and 40% were suffered in competitive games. 26% were recurring injuries, recurrent meniscus and patella tendon injuries took twice as long to recover compared to the initial injury.

Conclusion

Our findings suggest that MCL and patella tendon injuries are the most common knee injuries amongst professional footballers and that meniscus tears and ligament ruptures are relatively rare in comparison. Injuries appear to occur more frequently during training. A high proportion of injuries in the study received injection therapy in the form of PRP or sclerosant. The study suggests recurrent injuries can prolong recovery two-fold.
