How this affects your claim in practice
In a groin injury claim, the diagnosis is only the starting point. The records should connect x-ray, MRI, CT, ultrasound or specialist reports and certificate of capacity and rehabilitation notes with the worker's practical limits, including standing, walking, stairs, kneeling, squatting, driving and load carrying and safe duties that avoid unsafe mobility demands. If the insurer disputes whether the condition is traumatic, degenerative or a work aggravation, the response should address that reason directly.
Assessment source
- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- NSW Guidelines Chapter 3 applies AMA5 Chapter 17 only as modified by NSW. Paragraphs 3.2-3.7 require the most specific valid method, selection of the highest valid evaluation where more than one method applies, common units before combination, and a 40% WPI lower-limb maximum.
- NSW Guidelines para 1.24: activities of daily living must not be used to increase or reduce a calculated lower-extremity impairment. Functional examples explain the measurement; they are not an extra percentage.
- NSW Guidelines paras 3.8-3.15 and corrected AMA5 Tables 17-4 and 17-6: true leg length, gait, unilateral atrophy and manual muscle testing each have their own measurement and non-combination requirements.
- NSW Guidelines paras 3.16-3.18: inconsistent range-of-motion findings are invalid; values from different movement planes within one joint are added; joint ankylosis uses the corrected NSW optimum-position table and positional additions.
- NSW Guidelines paras 3.19-3.24: arthritis means radiological cartilage loss for impairment purposes. It cannot be assumed from pain, and the arthritis method cannot be combined with gait, atrophy, strength or range of motion.
- NSW Guidelines paras 3.10-3.15 and 3.32-3.35: gait is a last resort; gait, atrophy, muscle testing and peripheral-nerve methods can duplicate lower-limb function and must follow Table 17-2 non-combination rules; CRPS uses the NSW Chapter 17 method rather than AMA5 Chapter 18 pain.
- NSW Guidelines paras 3.26-3.30 and Tables 3.2-3.4: NSW modifies diagnosis-based estimates, tibial plateau fracture, patello-femoral and ankle replacement, tibia-os calcis angle and persistent plantar fasciitis. Hip and total-knee replacements use AMA5 Tables 17-33 to 17-35 subject to the NSW corrections.
What injuries or conditions may be assessed?
A groin presentation may arise from an adductor or iliopsoas injury, proximal rectus femoris injury, hip joint or labral pathology, pelvic injury, abdominal-wall or hernia condition, or a named nerve lesion.
- Because 'groin injury' describes a region rather than one diagnosis, the accepted anatomical condition must be identified before an impairment chapter or table can be selected.
- A hip or lower-limb diagnosis may use NSW Chapter 3; an abdominal, pelvic or neurological diagnosis may require a different body-system method and must not be forced into a hip percentage.
Symptoms and findings that matter
The examination should localise pain and loss to the hip joint, adductor or flexor unit, abdominal wall, pelvis or nerve distribution and record any reproducible movement, strength, sensory or structural finding for that diagnosis.
For groin injury, range of motion is normally measured three times in each relevant plane and the greatest valid result is used. If repeated readings or findings between examinations are materially inconsistent, ROM is not a valid impairment parameter.
If true leg length is relevant to groin injury, manual measurement is an exception to the greatest-reading rule: three readings are averaged. The opposite joint or limb is also compared where it provides a valid baseline.
Where groin injury is assessed through manual muscle weakness, the examiner uses the six Medical Research Council grades from 0 to 5. Those grades are ordinal rather than evenly spaced, and the NSW method uses AMA5 Table 17-8; electrodiagnostic results do not replace the manual muscle test.
An impairment report for groin injury may need a diagnosis-based estimate, radiological cartilage-loss method, replacement score, true limb-length difference, unilateral atrophy, muscle grade, named-nerve deficit or gait method instead of, or in a limited case alongside, ROM.
What investigations are usually relevant
Investigations for groin injury may include weight-bearing X-rays, CT, MRI, ultrasound or operation records identifying the actual joint, fracture, tendon, ligament, cartilage, prosthesis or nerve condition and repeat goniometer measurements, stability tests, alignment findings and comparison with the unaffected side where that comparison is valid. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Orthopaedic, rehabilitation and physiotherapy records showing whether the condition has reached maximum medical improvement.
- Certificates of capacity and duties evidence about walking, standing, stairs, kneeling, squatting, driving, lifting and uneven ground. These explain claim impact but do not alter the WPI calculation.
How WPI is assessed for this body part
There is no standalone WPI row for a general groin-injury label. The assessor selects the NSW body-system method for the accepted diagnosis and combines separate impairments only where the controlling rules permit.
For groin injury, NSW Guidelines Chapter 3 applies AMA5 Chapter 17 subject to NSW corrections. The most specific valid method is used, and where more than one valid method applies the highest valid evaluation is generally selected unless Table 17-2 permits a combination.
If ROM is valid for groin injury, values in different planes of the same joint are added. Regional values in the same limb are expressed in the same unit and combined before conversion to WPI.
For groin injury, hip flexion brings the knee towards the chest; extension moves the leg behind the body; abduction and adduction move it away from and towards the midline; internal and external rotation turn the thigh inward and outward.
Arthritis in an assessment of groin injury requires radiologically measured cartilage loss. For a knee, only the most impaired compartment is used. Arthritis cannot be combined with gait, atrophy, strength or ROM for the same loss.
For groin injury, gait remains a last-resort standalone method. Atrophy, manual muscle testing, peripheral nerve impairment and gait can duplicate strength loss and cannot be stacked. A diagnosis-based estimate is combined only where Table 17-2 permits it.
The calculation for groin injury cannot be changed because of activities of daily living under NSW paragraph 1.24. Functional descriptions help explain the evidence but are not an uplift or deduction.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Groin injury: diagnosis before percentage
Assumed facts: Assume a worker reports persistent groin pain after a lifting event. Specialist assessment identifies an accepted adductor tendon injury, while hip imaging and examination do not establish a separate joint impairment.
Method: The assessor considers the stable tendon and muscle findings under the permitted lower-limb method. A hip ROM or arthritis value is not inserted simply because the symptom location is the groin.
Illustrative outcome: No percentage can be selected without the measurements required by the accepted diagnosis. This is a method illustration, not an estimate for an individual worker.

What usually does not increase WPI
The site of pain, a short period away from work or a broad 'groin strain' label does not identify a WPI method by itself.
Pain, tenderness, swelling or difficulty walking does not create a percentage without a valid lower-limb method.
A scan label, surgery name or recommendation for surgery is not a fixed WPI result.
Work restrictions, weekly payments and inability to resume the pre-injury job are important claim issues but are not themselves impairment measurements.
Activities of daily living cannot be used to increase or reduce the calculated lower-extremity rating.
Evidence checklist
The records for groin injury should include the accepted diagnosis, side and body system rather than only the word 'groin' and clinical examination distinguishing hip, adductor, iliopsoas, abdominal-wall, pelvic and neurological findings. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- Relevant ultrasound, MRI, radiographs, operation records or specialist reports directed to the suspected structure.
- Repeat movement, strength, sensory or structural measurements required by the selected body-system method.
- Treatment records showing whether the condition has stabilised and whether another diagnosis remains under investigation.
How this injury commonly happens at work
Work-related groin injury can arise through slips, trips, falls or uneven surfaces and kneeling, squatting, climbing or stairs. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related groin injury can arise through lifting while twisting or carrying loads, vehicle, forklift or machinery incidents, and prolonged standing, walking or repetitive lower-limb loading. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For groin injury, an insurer may dispute whether the condition is traumatic, degenerative or a work aggravation and whether proposed duties exceed mobility restrictions. The written decision should be answered with evidence directed to those reasons.
Further disputes about groin injury may concern whether surgery, injections or rehabilitation are reasonably necessary, whether symptoms are consistent with imaging and examination, and whether weekly payments reflect real walking and standing limits. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of groin injury may involve physiotherapy, bracing, injections or specialist care and surgery such as repair, reconstruction, fixation or replacement where supported. The request should explain the expected functional benefit and its connection to the accepted injury.
Further management of groin injury may involve rehabilitation planning around stairs, driving and safe mobility and management of flare-ups during graded return to work. The request should explain why the proposed step is connected to the accepted injury and what functional improvement is expected.
Weekly payments and work capacity
Capacity evidence for groin injury should address standing, walking, stairs, kneeling, squatting, driving and load carrying and safe duties that avoid unsafe mobility demands. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For groin injury, capacity evidence should address travel to work and medication effects where relevant and weekly payment decisions where partial capacity is overstated. The question is whether those activities can be performed safely, reliably and for the proposed hours—not whether a task can be attempted once.
How NSW Work Injury Claim can help
For groin injury, a claim review can help to clarify diagnosis and mechanism of injury and compare work duties with medical restrictions. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For groin injury, a claim review can help to respond to treatment or work capacity disputes and prepare WPI evidence when the condition becomes stable. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
Common questions about groin injury claims
How can work cause or aggravate groin injury?
For groin injury, the relevant work history may include slips, trips, falls or uneven surfaces, kneeling, squatting, climbing or stairs, and lifting while twisting or carrying loads. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for groin injury?
For groin injury, there is no standalone WPI row for a general groin-injury label. The assessor selects the NSW body-system method for the accepted diagnosis and combines separate impairments only where the controlling rules permit. The examination should localise pain and loss to the hip joint, adductor or flexor unit, abdominal wall, pelvis or nerve distribution and record any reproducible movement, strength, sensory or structural finding for that diagnosis. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for a groin injury assessment?
A groin injury assessment commonly needs the accepted diagnosis, side and body system rather than only the word 'groin', clinical examination distinguishing hip, adductor, iliopsoas, abdominal-wall, pelvic and neurological findings, relevant ultrasound, MRI, radiographs, operation records or specialist reports directed to the suspected structure, and repeat movement, strength, sensory or structural measurements required by the selected body-system method. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about groin injury?
For groin injury, common issues include whether the condition is traumatic, degenerative or a work aggravation, whether proposed duties exceed mobility restrictions, and whether surgery, injections or rehabilitation are reasonably necessary. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can groin injury affect weekly payments and suitable duties?
Capacity evidence for groin injury may need to address standing, walking, stairs, kneeling, squatting, driving and load carrying, safe duties that avoid unsafe mobility demands, and travel to work and medication effects where relevant. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
Does groin injury automatically receive a fixed WPI percentage?
No. For groin injury, one verified example is regional groin symptoms: No standalone percentage; identify the accepted anatomical diagnosis, under NSW Guidelines paras 1.8-1.12 and 3.2-3.7. That value applies only when its stated criteria are met. The site of pain, a short period away from work or a broad 'groin strain' label does not identify a WPI method by itself.
