Provocative Test Write-Up: Three Maneuvers on J.M.'s Left Knee Two Days After Injury, the Lachman, the Pivot Shift and the Valgus Stress at 30 Degrees, Each With Position, Load, Structure and Reason
Two or Three, Not Twelve
Three tests were chosen because the mechanism, a noncontact valgus and rotation injury with rapid swelling, made three structures most likely: the anterior cruciate ligament, its function in rotation and the medial collateral ligament. Testing every structure in the knee would add findings without adding reasons.
Test 1: Lachman
Position: J.M. lying on the back, knee bent about 20 to 30 degrees, thigh muscles relaxed with a towel roll under the knee.
Load: the examiner held the thigh with one hand and pulled the shin forward with the other.
Structure stressed: the anterior cruciate ligament, which normally stops the tibia sliding forward on the femur.
Reason: the planted-foot mechanism and the hemarthrosis.
Result: J.M. reported mild discomfort. The examiner felt about 8 to 10 mm of forward movement with a soft end point, against about 3 mm with a firm end point on the right.
Test 2: Pivot Shift
Position: knee straight, then slowly bent while the examiner rotated the tibia inward and pushed the knee inward.
Load: combined valgus and inward rotation, reproducing the injury.
Structure stressed: the anterior cruciate ligament's role in controlling rotation.
Reason: to confirm rotational instability, which matters for treatment decisions.
Result: J.M. guarded and could not relax enough; the test was stopped as inconclusive. The patient reported apprehension; the examiner felt no clear shift.
Test 3: Valgus Stress at 30 Degrees
Position: knee bent 30 degrees, thigh supported on the table.
Load: inward force at the knee with the ankle held.
Structure stressed: the medial collateral ligament.
Reason: the valgus component of the mechanism.
Result: J.M. reported pain along the inner knee. The examiner felt slightly more opening than on the right, with a firm end point, a pattern that fits a partial tear rather than a complete rupture.
What a Negative Still Permits
The pivot shift was not positive, but it was not negative either; a guarded patient can make it appear normal. Even a truly negative pivot shift in the acute setting would not exclude a torn ligament, because the test is much less sensitive when the patient cannot relax. A meta-analysis found the Lachman test the most sensitive of the bedside tests and the pivot shift highly specific but less sensitive, especially without anesthesia (Benjaminse et al., 2006).
Conditions That Degrade a Test
Two days after injury the knee is swollen and painful, the thigh muscles guard, and the end point can be hard to feel. Each of these makes tests less accurate. The write-up records them so that a later examination, after swelling settles, can be read as a fresh test rather than as a repeat.
What the Tests Settle
The Lachman result, with a soft end point and twice the movement of the other side, makes an anterior cruciate ligament tear very likely. The medial collateral ligament is injured but stable. MRI was requested to confirm the anterior cruciate ligament tear and look for meniscal and bone bruise injury before any decision about surgery, consistent with the mechanism described in the video analysis of these injuries (Koga et al., 2010).
Plan for a Repeat Examination
The Lachman and pivot shift will be repeated at about ten days, once the effusion has settled and J.M. can relax the thigh. If the pivot shift becomes clearly positive, it adds weight to the decision about reconstruction for a cutting sport. The repeat will use the same positions and the same examiner where possible, so the comparison means something.

PA 530 Week 3 instructions, in plain terms
Week three focuses on two or three provocative tests, chosen for reasons. Explain why you chose those tests and not others, linking each to the mechanism or history. For every test, record the position the patient was placed in, the direction and type of load the examiner applied, the structure that load stresses and what in the account made it worth doing. Write each result in two halves: what the patient reported and what the examiner felt or saw, with comparison to the other side. Explain what a negative or inconclusive result still allows. List conditions that can degrade the tests, such as swelling or guarding. Say what the tests settle and what further step follows, and whether a repeat is needed. Cite evidence on test accuracy.
Inside the PA 530 Week 3 example
The write-up justifies three tests from J.M.'s noncontact valgus and rotation mechanism with rapid swelling. The Lachman is described with knee angle, towel roll, load direction and structure, and its result is split into mild discomfort reported and 8 to 10 mm of movement with a soft end point felt, against 3 mm on the right. The pivot shift is stopped as inconclusive because of guarding. Valgus stress at 30 degrees produces inner knee pain and slightly increased opening with a firm end point. A section cites Benjaminse and colleagues on sensitivity and specificity. Another lists swelling, pain and guarding as degrading factors. The tests are tied to the mechanism research, an MRI is requested and a repeat examination at ten days is planned.
Where the points sit in the PA 530 Week 3 rubric
Most points on this write-up depend on the four parts of each entry. A test named with only its result, missing position, load or structure, is where most marks disappear. The split result comes next: blending what the patient felt with what the examiner found is marked down. Choosing two or three tests with reasons earns credit, while performing many tests without justification costs marks for focus. The section on negative or inconclusive results is weighted, since overcalling a guarded test as normal is a common error. Degrading conditions and a repeat plan earn further credit. Evidence on accuracy should be cited correctly, and comparison with the uninjured side should appear in every result.
PA 530 Week 3 help from the desk
Many students lose marks here by listing a dozen tests with positive or negative beside each. Tell us the mechanism and findings in your case, and the write-up we draft would choose two or three tests with reasons, then record position, load, structure and rationale for each. Results are split into reported and observed halves with comparison to the other side. Inconclusive and negative results are interpreted with their limits, and conditions that degrade the exam are named. A repeat plan and next step follow. If your joint is a shoulder or ankle, the same four-part entries apply. Write up the tests you actually performed, using the model only as a check on format.

PA 530 Week 3 questions, answered
Do I have to give numbers for how well each test performs?
Only where your section asks, and then the source matters more than the figure. Published values for the same maneuver vary between textbooks, so a write-up quoting one names where it came from. Where no number is required, the equivalent move is a sentence saying what else could produce that same result in this patient.
My account describes an injury from two weeks ago. Does that change the write-up?
It changes what the entries can claim. A joint that has settled tests differently from one examined the same day, and stronger documents say which situation they are in before reporting anything. Send the account as written; the sample states the interval and lets every entry carry the qualification that interval earns it.
Can I include a test the account does not really justify?
Yes, in the closing block, as a maneuver considered and set aside with its reason in one clause. That is worth points, because it shows the field was surveyed before it was narrowed. What costs points is the same test promoted into the body with a justification written afterward to support it.
Where can I find a free PA 530 Week 3 sample paper?
This page carries the full PA 530 Week 3 provocative test write-up, the Lachman, pivot shift and valgus stress each with position, load, structure and reason.
Why is the pivot shift called inconclusive in the PA 530 Week 3 sample?
The patient guarded and could not relax, which can make the test look normal, so it was recorded as inconclusive and scheduled for repeat.
