What It Tests
Return to play decision making combines the test results, the time elapsed, the sport's demands and the athlete's own view, because none of those settles the question alone. 4.21.7 covers return to sport testing.
The examination's contribution is the structural and functional state, which is one input among several. 4.1.4 covers the structured approach.
It matters that the decision carries risk the athlete bears, so the clinician's role is informing rather than permitting. 4.22.8 covers the use of these scores.
How It Is Performed
Establish the sport, the position, the level and the point in the season, since all four change the stakes. 4.2.23 covers football.
Establish the time since surgery or injury against the expected biological timeline. 4.2.9 covers the onset.
Review the battery results, identifying which components pass and which limit. 4.21.7 covers return to sport testing.
Examine the knee, because a structural finding changes the conversation regardless of the functional results. 4.8.3 covers the bulge sign.
Establish the athlete's own confidence and their understanding of the risk. 4.22.6 covers the return to sport psychological measure.
Establish what the athlete wants and what they are prepared to accept, which is the part that is theirs. 4.22.8 covers the use of these scores.
Record the discussion and the decision, including any disagreement. 4.1.8 covers examination documentation.
What a Positive Means
A sound knee, a complete battery, a biologically adequate interval and a confident athlete is the straightforward decision.
A limiting component identifies what would need to change, which is more useful than a yes or a no. 4.21.7 covers return to sport testing.
A passing battery with a short interval is a conflict, and the interval is the constraint that performance cannot overcome. 4.2.9 covers the onset.
An athlete who wants to return against the testing is making a decision about their own risk, and the clinician's job is that it is informed. 4.22.8 covers the use of these scores.
A structural finding overrides the functional results, because the battery assumes a sound knee. 4.8.3 covers the bulge sign.
Key Learning Points
- No single input settles the question.
- The decision carries risk the athlete bears.
- A limiting component is more useful than a yes or a no.
- The biological interval is a constraint performance cannot overcome.
- A structural finding overrides the functional results.
MRCS Level
How It Is Performed
In a viva this is the decision question and the expected answer separates the clinician's contribution from the athlete's.
The expected points are the sport and context, the interval, the battery, the knee examination, the athlete's confidence, their wishes, and the record.
Say that the decision is shared, and name what each party contributes. 4.22.8 covers the use of these scores.
Say that a structural finding overrides a functional pass. 4.8.3 covers the bulge sign.
Say that you would record the discussion, including disagreement. 4.1.8 covers examination documentation.
What a Positive Means
The reasoning expected is that risk cannot be eliminated, so the decision is about an acceptable risk rather than a safe return. 4.21.7 covers return to sport testing.
Graft maturation and healing follow a biological timeline that function does not report on, which is why the interval is independent. 3.7.16 covers graft biomechanics.
The sport's demands determine which deficits matter, so the same test results support different decisions in different sports. 4.2.26 covers skiing.
An athlete's confidence predicts their return and their performance, which is why it is measured rather than assumed. 4.22.6 covers the return to sport psychological measure.
How Good It Is
The decision process is better documented than validated, which is the honest position.
Its best contribution is making the inputs explicit, so a decision can be examined afterwards. 4.1.8 covers examination documentation.
It does not reduce reinjury risk to a number, and claiming otherwise overstates what the testing supports. 4.21.7 covers return to sport testing.
No imaging and no test battery removes the judgement, so the process rather than the result is what is assessed. 4.1.6 covers that relationship.
No figures appear for any accuracy comparison on this page, under decision 023, and the comparison is the claim being made. Reinjury rates by return criterion are a literature question and this repository states none.
Key Learning Points
- The decision is about an acceptable risk rather than a safe return.
- The biological timeline is independent of function.
- The same test results support different decisions in different sports.
- Confidence predicts return and performance.
- Making the inputs explicit is the process's main contribution.
FRCS Level
How Good It Is
At decision level this is where the section's examination work is used, and its quality depends on the completeness of what preceded it.
A documented battery with an identified limiting component supports a specific conversation rather than a general one. 4.21.7 covers return to sport testing.
A conflict between the interval and the testing is resolved in favour of the interval on current understanding, and that position is stated rather than implied. 4.2.9 covers the onset.
An athlete returning against advice is documented, informed and supported, which is a different outcome from being refused. 4.1.8 covers examination documentation.
The sport's demand profile weights the components, so the decision is not uniform across sports. 4.2.25 covers rugby.
Where It Misleads
The commonest error is presenting the decision as the clinician's to make. 4.22.8 covers the use of these scores.
The battery is treated as validated for this purpose, which overstates it. 4.21.7 covers return to sport testing.
The interval is overridden by good test results, which reverses the relationship. 4.2.9 covers the onset.
The psychological component is omitted, so a physically ready athlete returns without confidence. 4.22.6 covers the return to sport psychological measure.
The discussion is not recorded, which removes the only evidence that it was informed. 4.1.8 covers examination documentation.
Key Learning Points
- Presenting the decision as the clinician's is the commonest error.
- Treating the battery as validated for this purpose overstates it.
- Good test results do not override the biological interval.
- An omitted psychological component returns an athlete without confidence.
- An unrecorded discussion leaves no evidence it was informed.
Fellowship Level
Where It Misleads
At fellowship level this decision is the section's least evidenced and most consequential, and the honest version says so.
The relationship between any set of criteria and reinjury is a literature question with a contested answer, and this repository supplies no figure for it. 4.21.7 covers return to sport testing.
Pressure from the athlete, the club and the season is part of the context and not part of the assessment, and separating them is the clinician's discipline. 4.23.2 covers the elite athlete.
A clinician's own risk tolerance affects the advice, which is a source of variation the process does not control for. 4.1.8 covers examination documentation.
The same athlete gets different advice at different points in a season, and that is a legitimate consequence of the demand changing rather than an inconsistency. 4.2.23 covers football.
Deferring the decision has its own cost, which is rarely weighed against the risk of returning. 4.22.8 covers the use of these scores.
Key Learning Points
- The link between criteria and reinjury is contested and no figure is supplied here.
- External pressure is context and not assessment.
- A clinician's risk tolerance is an uncontrolled source of variation.
- Different advice at different points in a season can be legitimate.
- Deferring has a cost that is rarely weighed.

References
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, which is decision 023 rather than an omission. The comparative standing of these tests is standard teaching and a specific sensitivity written from memory is the same class of claim as an invented citation, so ACC-001 refuses the number and the page states the comparison. A reviewer with the literature can add the figures into How Good It Is without restructuring the page, and chapter 3.17 lists the studies the figures would come from. Any measurement here, including a flexion angle, is written from standard teaching, has not been checked, and is registered under decision 006 in pipeline/config/figures with a verification state of UNVERIFIED_FROM_MEMORY.
