Housemaids knee is bursitis of –
**Core Concept**
Housemaid's knee is a common occupational injury characterized by inflammation of a specific bursa in the knee joint. It occurs due to repetitive trauma and friction, leading to swelling and pain in the affected area. This condition is often seen in individuals who engage in activities that involve frequent kneeling, such as housemaids, gardeners, or construction workers.
**Why the Correct Answer is Right**
The correct answer is prepatellar bursitis. The prepatellar bursa is a small fluid-filled sac located in front of the kneecap (patella), which helps reduce friction between the patella and the surrounding soft tissues. When this bursa becomes inflamed due to repetitive trauma or pressure, it leads to prepatellar bursitis, also known as housemaid's knee. The inflammation causes pain, swelling, and redness in the affected area.
**Why Each Wrong Option is Incorrect**
* **Option A:** Infrapatellar bursitis, also known as clergyman's knee, affects the bursa located below the kneecap, not in front of it.
* **Option B:** Suprapatellar bursitis affects the bursa located above the kneecap, which is not associated with housemaid's knee.
* **Option C:** Synovitis refers to inflammation of the synovial membrane surrounding the joint, rather than a specific bursa.
**Clinical Pearl / High-Yield Fact**
Housemaid's knee is often seen in individuals who engage in activities that involve frequent kneeling, making it essential to take regular breaks and maintain proper ergonomics to prevent this condition.
**Correct Answer:** C.
