ROS: cover all body systems that may help you include or rule out a differential diagnosis You should list each system as follows:  General:  Head:  EENT: etc. You should list these in bullet format and document the systems in order from head to toe.

Example of Complete ROS:

GENERAL:  Denies fever, chills, unintentional weight loss or gain, or loss of appetite.

SKIN:  Denies rashes, lesions, or moles.

CARDIOVASCULAR:  Denies chest pain or chest tightness. Denies palpitations or irregularities in rhythm. Denies peripheral edema or orthopnea.

Physical exam: From head-to-toe, include what you see, hear, and feel when doing your physical exam. You only need to examine the systems that are pertinent to the CC, HPI, and History. Do not use “WNL” or “normal.” You must describe what you see. Always document in head to toe format i.e. General: Head: EENT: etc.

VITAL SIGNS: Blood Pressure: 115/70, Pulse 82, RR 16, Oxygen Saturation 99% on room air, Temperature 98.3F orally, Height 6’0”, Weight 115lbs.

GENERAL:  Patient alert and oriented to person, place, and time. Cooperative and answers questions appropriately. Well-developed and well-nourished.

SKIN:  Intact, no lesions or rashes. Skin turgor good. No pallor, jaundice, or cyanosis present.

CARDIOVASCULAR: Heart rate and rhythm regular, S1 and S2 audible. No gallops, murmurs, valve clicks, or friction rub auscultated. No peripheral edema present.

RESPIRATORY:  Chest wall expansion and diaphragmatic excursion symmetrical. No rashes, lesions, accessory muscle use, or ecchymosis present. Breath sounds present and clear in all anterior and posterior lung fields, no adventitious sounds present. Tactile fremitus symmetric bilaterally, no crepitus palpated. Negative bronchoscopy. All areas resonant on percussion.

MUSCULOSKELETAL:  No swelling, edema, ecchymosis, or erythema present on bilateral knee inspection. Tenderness reported when bilateral knee palpated. Right knee- Flexion 5/5, painful, Extension 5/5, painful. Negative Lachman sign. Left knee- Flexion 5/5, painful; Extension 5/5, painful. Negative Lachman sign. Full ROM in all extremities.


Diagnostic results: Include any labs, x-rays, or other diagnostics that are needed to develop the differential diagnoses (support with evidenced and guidelines)

· Bilateral knee X-RAY

· CBC- rule out infection

· Uric acid- Rule out gout

· CT scan if XRAY negative for acute processes


Differential Diagnoses (list a minimum of 3 differential diagnoses). Your primary or presumptive diagnosis should be at the top of the list. For each diagnosis, provide supportive documentation with evidence-based guidelines.

1. Osgood Schlatter Disease

2. Tendonitis

3. Bursitis

4. Gout

5. Fracture

The primary diagnosis for this patient is Osgood Schlatter Disease (OSD). OSD is a non-traumatic knee problem that occurs in sports-active children aged 8-15 years (Leeuwen et al., 2022). OSD is characterized by knee pain and tenderness at tibial tuberosity that worsens during physical activity (Leeuwen et al., 2022).

Patellar tendinopathy occurs due to chronic, repative tendon overload (Aicale et al., 2020). Patient often complain of anterior knee pain and are unable to participate in physical activity due to pain (Aicale et al., 2020). This patient has full ROM in bilateral knees and is able to participate in physical activity, excluding this diagnosis as the primary diagnosis.

Bursitis and gout are listed as differential diagnosis but are not the primary diagnosis for this patient. Bursitis is inflammation of bursa causing limited ROM, pain with movement, and an erythematous, warm site (Ball et al., 2019). Gout occurs due to elevated uric acid levels causing a sudden onset of a hot, swollen joint (Ball et al., 2019). This patient did not have signs or symptoms of bursitis or gout, excluding this diagnosis.

A fracture occurs when there is a partial or complete break in the continuity of bone (Ball et al., 2019). Fractures are normally unilateral and occur due to trauma. This patient denies trauma or injury to area, excluding this diagnosis.

Differential Diagnoses

A sprained ankle is the most likely diagnosis, as the patient reports experiencing pain that started when she was playing soccer. She reports symptoms that are consistent with those of a sprained ankle. For example, she reports hearing a pop sound and ankle pain and can bear some weight on the ankle. While the condition can cause pain, swelling, tenderness and bruising, it is less likely to affect the patient’s ability to bear weight on foot (Tran & McCormack, 2020).

Fractured ankle- the patient presents with some symptoms that are consistent with a fractured ankle. The patient reports swelling, pain and a pop sound, which can be present in a fractured ankle. This condition was, however, eliminated as patients with the condition are often unable to bear any weight on the foot, which is unlike the patient (Gougoulias et al., 2020).

Ankle dislocation- happens when the ankle bones no longer meet properly. Patients will report experiencing sudden pain, swelling, and bruising. The injury is common among sports people as the patient. The condition was eliminated as the patient can bear weight on her ankle, which is impossible for patients with dislocations (Chi et al., 2021).

Achilles tendinitis- a condition caused by injury to the Achilles from overuse. Patients will often report experiencing pain at the back of the leg and, at times, near the ankle. The condition was eliminated as it is progressive and may cause stiffness and tenderness (Park et al., 2020). Additionally, the condition does not cause popping sounds.

Subtalar Joint Sprain can cause patients to experience ankle pain, swelling, bruising and joint instability (Wang et al., 2022). This condition was eliminated as the patient does not report that her ankle feels loose or wobbly.
