Is the patient's ongoing bilateral knee pain, which began in 1981 during military service, related to his military activities, including carrying heavy backpacks, and has persisted since his separation from service in 1982?

From the Guidelines

The patient's bilateral knee pain is directly related to his military service, as the onset of symptoms occurred during service and has persisted continuously since discharge, with the mechanism of injury being consistent with the development of chronic knee pathology. The patient is a veteran who served from June 20, 1979, to July 13, 1982, presenting with bilateral knee pain that originated during military service in 1981 while stationed in the Marianas. The patient reports that his knee pain began specifically when carrying heavy backpacks up mountainous terrain during his service, which is a known risk factor for osteoarthritis (OA) as stated in the 2020 VA/DoD Clinical Practice Guideline for the Non-Surgical Management of Hip & Knee Osteoarthritis 1. This pain has persisted continuously since his military discharge in 1982, affecting both knees but recently requiring surgical intervention for the left knee. The patient is currently in post-operative recovery from left knee surgery and is seeking documentation to establish a service connection for his bilateral knee condition for VA benefits purposes.

History of Present Illness (HPI)

• The patient's knee pain began in 1981 during military service
• The pain is associated with carrying heavy backpacks up mountainous terrain
• The pain has persisted continuously since military discharge in 1982
• The patient has undergone recent surgical intervention for the left knee
• The patient is seeking documentation to establish a service connection for his bilateral knee condition for VA benefits purposes The chronology presented indicates a direct temporal relationship between the onset of symptoms and military service activities, with no resolution of symptoms in the intervening years since separation from service. The mechanism of injury—carrying heavy loads while navigating difficult terrain—is consistent with the development of chronic knee pathology, as repetitive stress and weight-bearing activities are known risk factors for degenerative joint conditions, as supported by the 2020 VA/DoD Clinical Practice Guideline for the Non-Surgical Management of Hip & Knee Osteoarthritis 1, 2, 3.

From the Research

History of Present Illness

The patient is a veteran who served from 6/20/79 to 7/13/82 and is currently recovering from recent left knee surgery. He reports that his bilateral knee pain began in 1981 during his military service in the Marianas, where he carried heavy backpacks up high mountains. The knee pain has continued consistently since his separation from service in 1982.

• The patient's occupation during military service involved physical demands that may have contributed to the development of osteoarthritis, as suggested by a study published in 2019 4.
• The patient's symptoms are consistent with osteoarthritis, which is a common condition that can cause knee pain and is often associated with physical demands and trauma, as discussed in a study published in 2006 5.
• The patient's history of carrying heavy backpacks and engaging in physical activities during military service may have increased his risk of developing osteoarthritis, as noted in a study published in 2019 4.

Treatment and Management

The patient recently underwent surgery on the left knee, and he is requesting documentation connecting his ongoing knee condition to his military service for veterans benefits purposes.

• The patient's treatment options for osteoarthritis may include acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), and other medications, as discussed in studies published in 2003 6, 2011 7, and 2021 8.
• The patient's response to treatment may vary depending on the severity of his osteoarthritis and other individual factors, as noted in studies published in 2003 6 and 2011 7.
• The patient's documentation for veterans benefits purposes should include a detailed account of his medical history, including his military service and any relevant medical treatments or diagnoses, as suggested by the patient's history and symptoms.
