Football

For Medical Students

What It Tests

A football history tests what the knee was being asked to do, because the sport asks for repeated direction changes on a planted foot. 3.15.1 covers the mechanics.

Asking about the sport specifically establishes the likely mechanism, the likely associated injuries, and what the patient needs to get back to.

The last of those is the one that determines whether treatment succeeded, and it differs between a goalkeeper, a defender and a winger.

How It Is Performed

Ask what level they play at, how many times a week, and whether they are paid.

Ask what position, since the demands differ.

Ask what surface: grass, artificial turf, or indoor, because the shoe and surface interaction affects the forces the knee sees.

Ask what boots and studs they use, which is a modifiable factor patients rarely mention.

Ask about the injury itself in the terms of the sport: turning, shooting, being tackled, or landing. 4.2.16 covers non-contact mechanisms.

What a Positive Means

A non-contact turn or deceleration with a pop and immediate swelling is an anterior cruciate rupture, and football is the commonest setting for it in clinic.

A tackle from the outside forcing the knee inwards is a medial structure injury. 4.12.1 covers valgus stress testing.

A twisting injury with slower swelling and mechanical symptoms fits a meniscal tear.

A goalkeeper diving onto a flexed knee raises a direct blow and a patellar or osteochondral injury. 4.2.20 covers it.

Repeated anterior pain with no injury in an adolescent player is usually a loading problem rather than a structural one. 4.16.3 covers one version.

MRCS Level

What a Positive Means

The expected reasoning connects the sport's demands to the structures at risk.

Cutting and pivoting load the anterior cruciate and the anterolateral structures, which is why isolated cruciate injury is less common than teaching implies. 3.7.13 covers loading during cutting.

Contact tackles load the collaterals, and the medial side is involved far more often than the lateral.

Repeated submaximal loading in a growing player produces apophyseal and tendon problems rather than ligament injuries. 4.16.4 covers one.

A footballer with a cruciate injury should be assessed deliberately for meniscal and chondral injury, because the mechanism produces them together and the meniscal injury is the one with a repair window. 4.9.9 covers root tears.

How Good It Is

A sporting history performs well for anticipating the injury and for setting the rehabilitation target, and that second use is the one most often neglected.

It performs well for recurrence risk: a player returning to the same movement at the same level will see the same forces again.

It performs poorly as a diagnostic instrument on its own, since every injury in this chapter occurs in football.

The most useful single question is what level they intend to return to, because it changes the threshold for reconstruction more than any examination finding. 4.21.8 covers return to play decisions.

FRCS Level

How Good It Is

At decision level the football history determines the reconstruction conversation more than the laxity grade does.

A player who intends to return to pivoting sport is a stronger candidate for reconstruction, because the activity they cannot avoid is the one that provokes instability.

A recreational player who has already stopped is a different conversation, and the honest version of it includes the option of not reconstructing.

Age and intended level together predict both reinjury risk and graft choice discussion, and both come from the history. 3.17.1 covers the balance the literature supports.

The timing of the season is a real factor in the decision for a professional player and is not a clinical one, which is worth stating rather than pretending otherwise.

Where It Misleads

The commonest error is assuming a footballer wants to return to football. Many do not, and asking is quicker than assuming.

The second is accepting the player's or the club's timetable as a clinical constraint without saying what the cost is.

The third is missing the associated injury because the cruciate is the obvious one, which this chapter repeats because it is the commonest avoidable error in this group.

And a young player returning early to the same sport has a reinjury risk that should be discussed explicitly, since the contralateral knee is also at risk. 4.21.7 covers return to sport testing.

Fellowship Level

Where It Misleads

In referred practice the footballer with a failed reconstruction is the common presentation, and the history separates the causes.

A failure during the same cutting movement raises rotational control and tunnel position. 4.10.12 covers revision assessment.

A failure during a trivial movement raises graft choice, fixation, alignment or a deficient meniscus. 4.9.10 covers deficiency.

A player who never returned, with a stable knee, usually has a confidence or a rehabilitation problem rather than a structural one, and this is a larger group than the structural failures. 4.22.6 covers the relevant instrument.

Separating those three is a history task and determines whether the next intervention is an operation, a rehabilitation programme or a conversation.

No figure here supports their relative frequency, under decision 023.
