M70.42
Prepatellar bursitis, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Prepatellar bursitis, often called 'housemaid's knee,' is a condition involving inflammation of the bursa located in front of the kneecap (patella). When this inflammation occurs specifically on the left knee, it can cause discomfort, swelling, and reduced mobility. Recognized under the ICD-10 code M70.42, this condition is common among individuals with repetitive kneeling or minor knee injuries. The bursa acts as a cushion, reducing friction between tissues, but when inflamed, it can significantly impact daily activities.
Causes & Symptoms
Clinical Causes: Repeated or prolonged kneeling, especially on hard surfaces Trauma or direct injury to the front of the knee Overuse of the knee during activities like gardening, carpentry, or sports Infections from bacteria entering through a wound or skin break Underlying medical conditions such as gout or rheumatoid arthritis
Key Symptoms: Swelling in front of the kneecap Tenderness when touching the area Pain that worsens with kneeling or movement Restricted movement or difficulty straightening the knee Redness or warmth around the affected area In severe cases, fluid may ooze from a puncture wound or skin break
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a clinical examination where a healthcare professional assesses the swelling and tenderness of the knee. Further evaluation may include imaging tests such as ultrasound or MRI to visualize the Bursa and rule out other conditions. Sometimes, aspiration of the bursal fluid can help identify infection or other causes, guiding appropriate treatment options.
Treatment Protocols: Managing prepatellar bursitis involves a combination of approaches aimed at reducing inflammation and pain. Common treatments include: - Rest and avoiding activities that aggravate the condition - Applying ice packs to decrease swelling - Taking over-the-counter pain relievers or anti-inflammatory medications - Using protective padding or knee protectors during activities - Ensuring proper knee support and avoiding prolonged pressure on the knee - In cases of infection, antibiotics may be prescribed, and drainage of the bursa might be necessary - Physical therapy may be recommended to strengthen surrounding muscles and improve knee stability In persistent or severe cases, surgical intervention such as bursectomy (removal of the inflamed bursa) may be considered to resolve symptoms.
