ICD-10: Z96.65

The ICD-10 code Z96.65 refers to the "Presence of artificial knee joint." This code is used in medical documentation to indicate that a patient has an artificial knee joint, which is typically the result of knee arthroplasty, a surgical procedure that replaces a damaged or diseased knee joint with a prosthetic implant. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is essential for healthcare providers.

Clinical Presentation

Overview of Knee Arthroplasty

Knee arthroplasty is commonly performed for conditions such as osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. The procedure aims to relieve pain, restore function, and improve the quality of life for patients suffering from severe knee joint issues. The presence of an artificial knee joint can significantly alter a patient's clinical presentation.

Signs and Symptoms

Patients with an artificial knee joint may exhibit the following signs and symptoms:

• Pain Relief: One of the primary outcomes of knee arthroplasty is the reduction of pain. Patients often report significant pain relief post-surgery, although some may experience residual discomfort or pain due to various factors, including implant issues or soft tissue problems[1].

• Swelling and Stiffness: Post-operative swelling is common, especially in the initial weeks following surgery. Patients may also experience stiffness in the knee joint, particularly in the early stages of recovery[1].

• Range of Motion: Patients may have improved range of motion compared to their pre-operative state, but some may still face limitations. Physical therapy is often recommended to enhance mobility and strength[1].

• Instability or Weakness: Some patients may report feelings of instability or weakness in the knee, particularly if they have not engaged in rehabilitation exercises[1].

• Signs of Infection: In rare cases, patients may develop an infection around the artificial joint, which can present as increased redness, warmth, swelling, and pain at the surgical site. Fever may also be present[1].

Patient Characteristics

Certain characteristics are commonly associated with patients who have undergone knee arthroplasty:

• Age: Most patients are typically older adults, often over the age of 60, as degenerative joint diseases are more prevalent in this age group[1].

• Comorbidities: Many patients have comorbid conditions such as obesity, diabetes, or cardiovascular diseases, which can affect surgical outcomes and recovery[1].

• Activity Level: Pre-operative activity levels can vary widely. Some patients may have been highly active before their knee issues, while others may have been sedentary due to pain and mobility limitations[1].

• Gender: Studies indicate that women are more likely to undergo knee arthroplasty than men, often due to higher rates of osteoarthritis in females[1].

• Psychosocial Factors: Mental health status, including anxiety and depression, can influence recovery and rehabilitation outcomes. Patients with strong support systems tend to have better recovery experiences[1].
