Running

For Medical Students

What It Tests

A running history tests cumulative loading rather than a single event, because running knee problems are overuse problems almost without exception. 3.15.7 covers the mechanics.

Asking about it establishes what changed, since a knee that tolerated a training load for years and then stopped tolerating it usually met a change rather than a disease.

The two commonest presentations are anterior knee pain and lateral knee pain, and they have different causes and different answers.

How It Is Performed

Ask weekly mileage now and three months ago, because the change matters more than the number.

Ask about surface, gradient, footwear age and any change in any of them.

Ask about pace and session type, since interval and hill work load differently from steady running.

Ask when in a run the pain comes on and whether it stops them, because pain that appears at a consistent distance behaves differently from pain present from the start.

Ask about the hip and the foot, because both change knee loading and both are modifiable. 4.1.2 covers examining above and below.

What a Positive Means

Anterior pain, worse on hills and stairs and after sitting, is patellofemoral. 4.15.9 covers it.

Lateral pain coming on at a consistent distance and settling with rest is more often the iliotibial band than the lateral meniscus.

Medial joint line pain in an older runner with stiffness raises degenerative change. 4.18.1 covers early disease.

Pain below the patella, worse with hills and jumping, raises patellar tendinopathy. 4.16.3 covers it.

Pain that is present at rest, wakes the patient, or is not load-related is not an overuse problem and needs a different assessment. 4.2.13 covers night pain.

MRCS Level

What a Positive Means

The reasoning expected is from load per session and sessions per week to tissue capacity.

An overuse injury is a mismatch between load and capacity, so it can be produced by raising load or by lowering capacity, and the history has to ask about both.

Lowering capacity includes illness, sleep loss, nutrition, a change of job and a previous injury that changed mechanics.

The relationship between recreational running and degenerative change is not established, which 3.15.7 states plainly, and a runner should not be told their running caused their arthritis on this evidence.

Distance running is also a presentation where bone stress has to be considered, and the history feature is pain that no longer settles between runs.

How Good It Is

The running history is among the most useful in this chapter, because it identifies a modifiable cause rather than only a diagnosis.

It performs well for distinguishing overuse from structural injury, which is nearly always the question.

It performs well for identifying what to change, which is where the treatment lies.

It performs poorly in the runner who has not changed anything, where the cause is capacity rather than load and the history has to look wider.

FRCS Level

How Good It Is

At decision level the running history usually argues against an operation, which is its most useful contribution.

An overuse presentation with imaging findings is the classic trap: the findings are real, common in asymptomatic runners, and not the problem. 4.1.6 covers the era of imaging.

A runner with a genuine mechanical symptom is a different matter and should be assessed as any other patient with one. 4.2.7 covers mechanical symptoms.

The runner who most often benefits from surgery is the one with a structural injury sustained during running rather than because of it.

The counselling that matters most is about load management and expectations, and it is better delivered from a clear history than from a scan report.

Where It Misleads

The commonest error is operating on an overuse presentation because imaging found something.

The second is telling a runner to stop running without evidence that running is the problem, which is both unsupported and badly received.

The third is missing bone stress, particularly in a female runner with menstrual irregularity or low energy availability, where the differential extends well beyond the knee.

And lateral pain in a runner attributed to a lateral meniscal tear found on imaging is a recognisable error, because iliotibial band pain is far more common and the imaging finding may be incidental.

Fellowship Level

Where It Misleads

In referred practice the runner has usually had imaging, an injection or an arthroscopy and is no better, and the history has to establish whether the original problem was ever structural.

A runner whose pain is unchanged after a structural intervention almost always had an overuse problem, and the useful next step is a loading programme rather than a further procedure. 4.2.34 covers rehabilitation.

A runner who improved and relapsed on returning to the same training load has had their diagnosis confirmed and their training not addressed.

Persistent anterior pain in a runner after an arthroscopy raises a chondral lesion, patellofemoral overload or a pain process, and the history separates them better than further imaging. 4.15.9 covers the presentation.

No figure here supports these claims, under decision 023.
