Name of the Condition
- Unilateral primary osteoarthritis, right knee
- Also known as degenerative joint disease of the right knee
Summary
Unilateral primary osteoarthritis of the right knee is a degenerative joint condition where the cartilage that cushions the right knee joint wears down over time. This leads to pain, stiffness, and decreased mobility in the affected knee.
Causes
- Aging and natural wear-and-tear on the knee joint
- Previous knee injuries or trauma
- Chronic stress on the knee from repetitive motion or excessive activity
Risk Factors
- Age: More common in individuals aged 50 and older
- Obesity: Increased weight places additional stress on knee joints
- Genetic predisposition: Family history of osteoarthritis
- Gender: Higher prevalence in females
- Occupations or sports involving heavy use of knees
Symptoms
- Pain and tenderness in the right knee
- Stiffness, especially after resting or first thing in the morning
- Swelling and inflammation around the knee joint
- Reduced range of motion or difficulty walking
- Crepitus (grating sensation) during knee movement
Diagnosis
- Physical examination by a healthcare provider
- Imaging tests such as X-rays to assess joint damage
- MRI may be used for detailed imaging if needed
- Consideration of medical history and symptom patterns
Treatment Options
- Medications: NSAIDs for pain relief and reducing inflammation
- Physical Therapy: Exercises to strengthen muscles around the knee and improve flexibility
- Lifestyle Modifications: Weight loss to alleviate pressure on the knee
- Injections: Corticosteroids or hyaluronic acid injections for pain relief
- Surgery: Knee arthroscopy or knee replacement in severe cases
Prognosis and Follow-Up
- Progressive condition with variable rate of progression
- Regular follow-ups necessary to monitor joint health and adjust treatments
- Good pain management and therapy can significantly improve quality of life
Complications
- Chronic pain and increased disability
- Joint instability or leg deformities
- Risk of falls due to decreased knee function
Lifestyle & Prevention
- Maintain a healthy weight to reduce knee strain
- Engage in low-impact exercises like swimming or cycling
- Practice joint protection techniques during activities
- Use supportive footwear
When to Seek Professional Help
- Persistent or worsening knee pain
- Sudden swelling or severe knee deformity
- Inability to bear weight on the affected knee

Tips for Medical Coders
- Ensure laterality is documented: right knee
- Verify documentation distinguishes between primary (idiopathic) and secondary osteoarthritis
- Be aware of common coding errors such as omitting the specification of the knee affected
