Bipartite patella

Bipartite patella is a condition where the patella, or kneecap, is composed of two separate bone fragments instead of being a single, unified bone.

This developmental anomaly occurs when the ossification centers in the patella fail to fuse during growth.

It is generally considered a normal anatomical variation, present in about 1-2% of the population, and most often affects males more than females.

In most cases, a bipartite patella is asymptomatic and is discovered incidentally during imaging for unrelated conditions.

However, it can sometimes lead to anterior knee pain, especially following trauma or overuse, due to irritation or inflammation at the junction of the two bone pieces.

Diagnosis is typically confirmed via X-ray, which can clearly show the unfused bone fragments.

In some cases, additional imaging like MRI might be used to evaluate any associated soft tissue or cartilage issues.

Treatment is usually conservative, involving rest, ice, and nonsteroidal anti-inflammatory drugs (NSAIDs) to alleviate pain.

In rare cases where symptoms are persistent, surgical intervention may be considered to remove or fixate the separate bone fragment.

Overall, bipartite patella is a benign condition with a favorable prognosis, and most individuals do not experience significant functional limitations.
