What It Tests

A tennis history tests the combination of repeated deceleration and direction change, which loads the knee in both the sagittal and the rotational planes. 3.15.4 covers the mechanics.

It also tests age and surface, because tennis is played across a wider age range than most court sports and the surface changes the sliding and therefore the loading.

The presentations split between overuse in the older recreational player and acute injury in the younger competitive one.

How It Is Performed

Ask the level, the frequency and the surface: hard court, clay, grass or indoor.

Ask whether the problem began during a specific shot or point, or built up over weeks.

Ask about the serve, since the knee is loaded in deep flexion and then extended explosively.

Ask about lunging and sliding, because a slide on clay unloads the knee rotationally and a hard court does not.

Ask about footwear, which on a hard court is a genuine variable.

What a Positive Means

An acute twist during a direction change with immediate swelling is a cruciate or meniscal injury as in any pivoting sport. 4.2.18 covers twisting injuries.

Anterior pain during serving and lunging, building over weeks, is patellofemoral or patellar tendon overload. 4.16.3 covers one version.

Medial joint line pain in an older player with stiffness raises degenerative change plus a degenerate meniscal tear. 4.9.11 covers the combination.

Posterior pain during a lunge raises a hamstring origin or a cyst rather than the joint. 4.6.10 covers the popliteal fossa.

A sudden calf or posterior knee pain during a push off is a muscle or tendon injury rather than a joint one.

Key Learning Points

Tennis loads the knee in both the sagittal and rotational planes repeatedly.
The surface changes sliding and therefore loading: clay unloads rotationally, hard courts do not.
Older recreational players present with overuse; younger competitive ones with acute injury.
Anterior pain during serving and lunging is patellofemoral or patellar tendon overload.
A sudden posterior pain on push off is muscle or tendon rather than joint.

What a Positive Means

The expected reasoning connects the stroke to the load.

The serve loads the knee in deep flexion and then in explosive extension, which is a patellofemoral and extensor mechanism load. 3.12.3 covers contact pressures.

A lunge loads the knee in flexion with rotation, which is a meniscal load.

A direction change on a planted foot loads the cruciate and the anterolateral structures, as in any pivoting sport.

The older recreational player's knee is commonly degenerate before the tennis, which means a minor event can produce a significant symptom and the history will sound trivial.

How Good It Is

The tennis history performs well for separating overuse from acute injury, which is the main division in this population.

The stroke at which the symptom occurs is reasonably specific and is reliably recalled, because players think in strokes.

It performs poorly for structural diagnosis in the degenerate knee, where the trivial event and the significant symptom give an uninformative combination.

Surface and footwear are modifiable and the history is the only route to them.

Key Learning Points

The serve is a patellofemoral and extensor mechanism load; the lunge is a meniscal one.
Players think in strokes, so the stroke at which it happens is reliably recalled.
In the degenerate knee a trivial event with a significant symptom is uninformative.
Surface and footwear are modifiable and only the history reaches them.

FRCS Level

How Good It Is

At decision level the tennis history matters mostly for the older recreational player, who is the commonest presentation.

A degenerate knee with a meniscal tear in a player who wants to keep playing is the clearest application of the meniscectomy trial evidence, and the honest answer is usually non-operative first. 4.9.11 covers the point.

The exception is a genuine mechanical block, which remains a surgical indication whatever the degenerative background. 4.2.5 covers locking.

In a younger competitive player the decisions are the same as for any pivoting athlete, and the return target is set by the demands rather than the sport. 4.21.8 covers return to play.

Where It Misleads

The commonest error is arthroscopy for a degenerate meniscal tear in a tennis player whose symptom is pain, because the sport makes the demand feel like an indication.

The second is dismissing an older player's demand as recreational, which under-treats a patient for whom the sport may be their main physical and social activity.

The third is attributing posterior or calf symptoms to the knee.

And a tennis player with anterior pain and no injury should have their serve and training load considered before their joint surfaces.

Key Learning Points

A degenerate tear in a player whose symptom is pain is usually non-operative first.
A genuine mechanical block remains surgical whatever the degenerative background.
The sport can make a demand feel like an indication, which is the error to guard against.
Dismissing an older player's demand as recreational under-treats them.
Consider the serve and the training load before the joint surfaces.

Where It Misleads

In referred practice the tennis player presents after an arthroscopy that did not help, and the history establishes whether the symptom was ever mechanical.

A player whose pain was load related and diffuse before the operation and is unchanged after it had degenerative pain, and the next step is load management, injection or eventually arthroplasty rather than a further arthroscopy.

A player with a mechanical symptom that persists raises a retained fragment, a new tear or an unaddressed chondral lesion. 4.17.5 covers cartilage defects.

An older player considering arthroplasty who wants to return to tennis needs an explicit conversation about what the implant tolerates, and the history of their intended play is what makes that concrete. 4.20.8 covers assessment.

No figure here supports these claims, under decision 023.

Key Learning Points

Pain unchanged after arthroscopy was degenerative, and the next step is not another arthroscopy.
A persisting mechanical symptom raises a retained fragment, a new tear or a chondral lesion.
A player wanting to return to tennis after arthroplasty needs an explicit conversation.
Their intended level of play is what makes that conversation concrete.

No reference list is attached to this draft. Evidence verification has not run, because source retrieval was unavailable at generation time. Under the Operations Handbook a missing reference is acceptable and an invented one is a critical failure, so nothing has been cited and no citation marker appears in the text. This page carries no diagnostic accuracy figure either, which is decision 023 rather than an omission: the comparative value of the history questions is standard teaching and a specific sensitivity written from memory is not, so ACC-001 refuses the number and the page states the comparison. Any measurement on this page is written from standard teaching, has not been checked against a source, and is registered under decision 006 in pipeline/config/figures with a verification state of UNVERIFIED_FROM_MEMORY.
