Z89.52
Acquired absence of knee
Clinical Classification Guidelines
Inclusion Terms
- Acquired absence of knee joint following explantation of knee joint prosthesis, with or without presence of antibiotic-impregnated cement spacer
Medical Intelligence & Overview
ICD-10 Code Z89.52 refers to an acquired absence of the knee, which typically results from surgical removal or loss of a knee joint, often due to medical necessity such as severe injury, infection, or failure of a knee prosthesis. This condition signifies that part or all of the knee joint has been removed or is missing as a result of medical intervention. It is important to understand the circumstances that lead to this condition, how it is identified, and the types of treatments involved.
Causes & Symptoms
Clinical Causes: Explantation of knee joint prosthesis due to infection, loosening, or failure Severe knee injuries or trauma leading to joint destruction Severe cartilage degeneration unresponsive to conservative treatment Development of complications from previous knee surgeries Presence of infections such as osteomyelitis affecting the knee joint Use of antibiotic-impregnated cement spacers during revision surgeries Necrosis or ischemia causing tissue death around the knee joint
Key Symptoms: Loss of knee joint function Limited or no mobility in the affected limb Persistent pain or discomfort in the limb Swelling or inflammation around the surgical site Weakness or instability of the leg Altered gait or difficulty walking Psychological effects such as emotional distress or depression due to limb loss
Diagnostic & Treatment
Diagnosis Path: Diagnosis of an acquired absence of the knee involves a thorough clinical evaluation, review of surgical history, and physical examination. Imaging studies such as X-rays, MRI, or CT scans help confirm the extent of joint removal and verify the absence of the joint. Medical professionals also assess for signs of ongoing infection or other complications. Documenting prior surgical procedures, including the presence or absence of a prosthesis and any spacers used, is essential for accurate classification. The ICD-10 code Z89.52 specifically reflects cases where the knee has been surgically removed, with or without the use of antibiotic-impregnated cement spacers during procedures.
Treatment Protocols: Amputation or limb reconstruction procedures, depending on the underlying cause and extent of tissue removal Prosthetic limb fitting to restore mobility and function Physical therapy to improve strength, mobility, and adaptation to prosthesis Pain management strategies to alleviate discomfort Psychological support or counseling to address emotional impacts Management of infections or other complications that may arise post-surgery
