S83.101A Unspecified subluxation of right knee, initial encounter

ICD10CM code

#### Name of the Condition
- Unspecified Subluxation of Right Knee, Initial Encounter
- Technical term: Knee subluxation

#### Summary
- This condition refers to a partial dislocation of the right knee that is not specifically classified. It usually occurs when the knee bones are temporarily displaced, typically causing pain and instability.

#### Causes
- Common causes include trauma or injury to the knee, such as a fall, sports injury, or accident. It can also result from ligament laxity or muscle weakness around the knee joint.

#### Risk Factors
- Factors include engaging in high-impact sports, previous knee injuries, poor conditioning or muscle strength, and participation in activities that involve sudden directional changes.

#### Symptoms
- Common symptoms include knee pain, discomfort, a feeling of instability or the knee giving way, swelling, and limited range of motion.

#### Diagnosis
- Diagnosis typically involves a physical examination, patient history, and imaging tests like X-rays or MRIs to evaluate joint structure and rule out other injuries.

#### Treatment Options
- Non-surgical treatments include rest, ice, compression, elevation (R.I.C.E.), knee braces, physical therapy, and pain medication.
- In severe cases, surgical intervention might be necessary to correct the joint alignment or repair ligaments.

#### Prognosis and Follow-Up
- With appropriate treatment, patients often recover well, though it may take several weeks to months. Follow-up appointments are crucial to monitor recovery progress.

#### Complications
- Without proper treatment, there can be recurrent instability, increased risk of osteoarthritis, chronic pain, or further joint damage.

#### Lifestyle & Prevention
- Strengthening exercises for the muscles surrounding the knee and maintaining a healthy weight can help prevent subluxations. Avoiding high-risk activities or using protective equipment can also be beneficial.

#### When to Seek Professional Help
- Immediate medical attention is needed if there is severe knee pain, inability to bear weight, significant swelling, or visible deformity of the joint.
