Undisplaced fracture patella treated with
**Core Concept**
The treatment of an undisplaced fracture patella involves minimizing pain, maintaining knee function, and promoting early mobilization. The goal is to restore the normal anatomy and function of the knee joint, with minimal intervention to avoid complications.
**Why the Correct Answer is Right**
The correct treatment for an undisplaced fracture patella is usually conservative management, which includes a period of immobilization in a knee splint or cast to allow the fracture to heal. This approach takes advantage of the patella's fibrous and cartilaginous attachments, which can stabilize the fracture and promote healing. The quadriceps muscle and patellar tendon also play a crucial role in maintaining the patella's position and function during the healing process.
**Why Each Wrong Option is Incorrect**
**Option A:** Surgical intervention is usually reserved for displaced or comminuted fractures of the patella, where conservative management is unlikely to achieve satisfactory results.
**Option B:** Total knee arthroplasty is a major surgical procedure typically reserved for advanced knee arthritis or severe knee deformity.
**Option C:** Closed reduction and percutaneous pinning may be considered for certain types of patellar fractures, but it is not the first-line treatment for undisplaced fractures.
**Clinical Pearl / High-Yield Fact**
It is essential to differentiate between displaced and undisplaced patellar fractures, as the treatment approach and prognosis differ significantly between the two.
**Correct Answer: D. Immobilization in a knee splint or cast.**
