Flow Knows - Nicky Ryan's knee injury, posterolateral corner injuries and management

Craig and Jason discuss Nicky Ryan’s knee injury and hypothesise about structures potentially injured given the mechanism and immediate footage post match.

They also discuss the anatomy, mechanism of injury and management pathways for posterolateral corner injuries that they have commonly seen in BJJ practitioners, soccer players and rugby league players.

Flow Knows Conor McGregor's leg fracture, Tommy Turbo's hamstring and what you can be doing during Lockdown to minimise injury

Craig and Jason discuss their thoughts on Conor's fracture and the possible causes, Tommy Turbo's hamstring, the Quadrant of Doom for hamstring injuries and what you can be doing during the Sydney lockdown period to minimise injury.

Hamstring health, performance and injury prevention

With new COVID lockdowns in place for Greater Sydney and community sport taking a 2 week break, we often see these types of unscheduled breaks lead to injuries when sport resumes.

Planning ahead and implementing some strategies for injury prevention will help you navigate the lockdown break and keep you on the pitch for longer.

Hamstring injuries are common amongst professional footballers and Sunday afternoon superstars alike.

Some research into hamstring injuries has demonstrated that if the hamstring musculature is strong and flexible as opposed to weak and short then it significantly decreases the risk of hamstring injury throughout the course of a season (Timmins et al. 2016 and Bourne et al. 2018). 

The Quadrant of Doom

Below is an infographic from YLM Sports Science that clearly demonstrates the relationship between strength, flexibility and injury risk. The other way to frame this is in terms of capacity. The greater the strength and movement capacity then the less likely things are to go wrong. 

The other benefit from all of the below is that by incorporating this it will not decrease injury risk but also improve performance!

Knowing this is all well and good but we also want to practically act on this. How do we build things up from a loading, flexibility and strength point of view. Below is another great infographic from YLM Sports Science that shows specific ways to address all these areas.

In summary to build strong, functional and flexible hamstrings then it is worth looking at an exercise program that includes hip and knee dominant exercises that is gradually overloaded to create adaptation. It is also worth adding some running and sprint work into the program as this is shown to have a protective effect and also some loaded flexibility work to strengthen the hamstrings in lengthened positions (Oakley et al.2018).

Take Home points for hamstring performance and health:

  • Strong and long hamstrings are the goal

  • Use knee and hip dominant strengthening exercises

  • Incorporate sprint work

  • Work on flexibility

  • Progressively overload

  • Stay consistent
