What It Tests

A cricket history tests which role the patient plays, because a fast bowler, a batter and a fielder ask different things of the knee. 3.15.2 covers the mechanics.

The fast bowler's front leg absorbs a very large braking force at front foot contact, repeated many times in a session.

The batter turns and accelerates on a planted foot while carrying a bat, and the fielder dives, slides and throws.

Asking which role comes first, because it changes the whole differential.

How It Is Performed

Ask what they do in the team: bowl, bat, field, or keep wicket, and how much of each.

If they bowl, ask how many overs in a spell and in a day, and whether the workload recently increased.

Ask whether the pain is worse during the delivery stride, on landing, on turning for a run, or on diving.

Ask about the surface and the footwear, since spikes on a hard dry surface change the loading.

Ask about the back, hips and ankles, because bowling loads all of them and a knee symptom may be compensatory.

What a Positive Means

Front knee pain on landing in a fast bowler, worse as a spell goes on, suggests an overload problem: patellar tendinopathy, patellofemoral overload or a stress response. 4.16.3 covers one version.

A twisting injury turning for a second run is a meniscal or cruciate mechanism like any other. 4.2.18 covers twisting injuries.

A diving fielder landing on a flexed knee raises a direct blow and a chondral or patellar injury. 4.2.20 covers it.

A wicketkeeper's knee pain from prolonged deep squatting is patellofemoral loading. 4.15.9 covers it.

Pain that began after a workload increase, in a knee with no injury, is almost always a loading problem rather than a structural one.

MRCS Level

What a Positive Means

The reasoning expected is from repetition and magnitude to tissue response rather than to a single failure.

Repeated high magnitude eccentric loading produces tendinopathy and bone stress rather than ligament rupture, which is why the cricket differential looks different from the football one.

Front foot contact in fast bowling produces a braking impulse that the quadriceps absorbs eccentrically, which is the mechanism behind anterior knee problems in that group.

A sudden structural injury in cricket is most often a fielding or running injury rather than a bowling one.

Workload change is the single most useful historical feature in an overuse presentation, and it is rarely volunteered.

How Good It Is

The cricket history performs well for separating overuse from injury, which is its main job, and the separation is nearly complete once the role and the onset are known.

It performs well for identifying modifiable factors, since workload, technique and footwear are all adjustable and all come from the history.

It performs poorly for identifying structure in an acute injury, where the mechanism questions in this chapter do the work instead.

The season structure matters: a problem arising in pre-season loading behaves differently from one arising mid-season.

FRCS Level

How Good It Is

At decision level the cricket history mostly steers away from surgery, which is a useful thing for a history to do.

An overload presentation in a bowler is a load management and rehabilitation problem, and the intervention is the workload rather than the knee.

A structural injury in a cricketer is managed as it would be in any other athlete, with the return target set by the role rather than by the sport.

The role also determines what counts as recovery. A bowler needs to tolerate repeated eccentric braking and a batter needs to turn and accelerate, and a rehabilitation programme that does not distinguish them will fail one of them. 4.21.7 covers return to sport testing.

Where It Misleads

The commonest error is treating a bowler's anterior knee pain as a structural problem because imaging shows a finding. Imaging in loaded athletic knees frequently shows findings.

The second is missing the kinetic chain. A knee symptom in a bowler can follow a hip, back or ankle restriction, and treating the knee leaves the cause. 4.1.2 covers examining the joint above and below.

The third is accepting a workload history from the player rather than from the records, which at professional level exist and are more accurate.

And a young fast bowler with knee pain and a recent growth spurt has a different differential from an adult. 4.19.1 covers growth plate assessment.

Fellowship Level

Where It Misleads

In referred practice the cricketer presents with a chronic anterior knee problem that has resisted rehabilitation, and the history has to establish what rehabilitation was actually done. 4.2.34 covers it.

A patellar tendinopathy that has not responded to a progressive loading programme is different from one that has never had one, and the second is far more common.

A bowler with persistent front knee pain and a normal examination may have bone stress rather than tendon pathology, and the history feature that suggests it is pain that no longer settles between sessions.

A patellofemoral chondral injury from a diving fielding injury years earlier is a recognised cause of persistent anterior pain, and the historical event is often the only clue. 4.2.20 covers direct blows.

No figure here supports these claims, under decision 023.
