Getting in was the standard you already passed
Retention is a separate question, asked continuously, against a different measure: not whether you were an acceptable risk on the day you enlisted, but whether you can currently deploy and do the job. People are often surprised by that, usually at the point where a foot they have been quietly managing for four years stops being quiet. Seven beliefs about it, checked.

What people believe about medical boards
“If I got in, I am fine for the rest of my career.” Why they are separate questions
Accession asks whether you are an acceptable risk to take on. Retention asks whether you can currently deploy and perform, and it is asked again every time something changes: an injury, a new symptom, a failed test, a profile that lasts too long.
The difference matters most for conditions that progress. A treated clubfoot (talipes equinovarus, CTEV) that is fine at nineteen may be a different foot at thirty-two, and the retention standard is applied to the foot you have now.
“A medical board means I am being discharged.” What actually happens
An evaluation board exists to determine whether you still meet retention standards1. Outcomes include returning to full duty, returning with limitations, reclassification into a different role, or separation. Several of those keep you in.
It is a serious process and it is a process, not a verdict. Treating it as an automatic ending leads people to conceal problems until the options genuinely have narrowed.
“A profile will end my career, so I should avoid one.” The arithmetic of hiding it
A temporary profile that lets tissue recover is often the difference between a six-week problem and a permanent one. Concealing a problem does not stop it progressing; it removes every option that only exists while it is still small.
What is true is that a permanent profile restricting core duties raises real questions about deployability. That is a reason to seek help early, while a temporary profile is still sufficient, and not a reason to avoid the system entirely.
“My clubfoot was declared at enlistment, so it is covered.” What declaration actually does
Declaring it was necessary and it protects you from the far worse problem of undisclosed history. What it does not do is exempt the condition from later review if it starts limiting your duty.
Where declaration genuinely helps is in establishing a baseline. A documented starting point makes it possible to show what changed and when, which matters both clinically and for any later question about whether service aggravated it.
“Nothing has changed, so there is nothing to document.” Why the quiet years matter
Documentation while everything is fine is what makes a later change legible. Without a baseline, a problem appearing in year six looks like a pre-existing condition finally declaring itself; with one, it is a measurable deterioration over a documented period of service.
Get an assessment early in your career, keep copies of everything, and note when things change. It costs almost nothing at the time and it is impossible to reconstruct afterwards.
“It only matters if I cannot pass the fitness test.” What the real threshold is
Passing a fitness assessment is one narrow input. The retention question is whether you can deploy and carry out your role, which includes wearing the kit, carrying the load, working in the conditions and being available when needed.
People who pass every test and cannot tolerate boots for a full duty day are in a more precarious position than the score suggests. Conversely, a limitation that does not affect deployability may matter far less than it feels like it should.
“This is all a long way off. I will deal with it if it happens.” When the decisions actually get made
The board may indeed be years away or never happen. What is happening now is the accumulation of the record it would be based on: whether you were assessed, whether changes were noted, whether problems were raised early enough to be managed.
Almost everything that determines how a retention question resolves is decided long before anyone convenes to consider it. That is the part worth acting on today.
Why problems arrive late
Accumulated load is the explanation for most of it. Years of rigid boots, hard surfaces and carried weight place demands on a foot that a civilian life never would, and cartilage and tendon respond to that on a timescale of years instead of weeks. A joint already carrying a residual deformity has less margin to spend, so it spends it faster.
The pattern is consistent enough to be worth naming: nothing at all through training, nothing much through the first posting, then a gradual increase in how long recovery takes, then something that does not settle. That is the arc, and the useful intervention points are all in the middle of it, not at the end.
The best time to document a foot that is fine is while it is still fine.
If you are already in the middle of this
Get everything in the medical record, including the things that seem too minor to mention. Keep your own copies. Note dates and what triggered a flare, because a pattern documented across two years is a far stronger position than a description given from memory.
Raise problems while they are still small enough for a temporary profile to solve. Be accurate about what you can and cannot do instead of heroic in either direction. Overstating your capability produces a worse outcome than describing it plainly, and so does understating it. And find out what your service’s own process actually involves instead of relying on what people tell each other, because the informal version is usually wrong in both directions.
