Summary

Operative treatment for patella fractures leads to persistent functional deficits and symptomatic complaints at midterm follow-up. Surgeons should counsel patients on these long-term outcomes after patella fracture surgery.

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...

Journal of orthopaedic trauma·2025

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Rehabilitation Medicine

Background:

  • Patella fractures are common injuries requiring surgical intervention.
  • Midterm functional outcomes after operative treatment for isolated patella fractures are not well-documented.

Purpose of the Study:

  • To evaluate midterm functional outcomes in patients who underwent operative treatment for isolated patella fractures.
  • To identify persistent symptomatic complaints and functional deficits.

Main Methods:

  • Prospective and retrospective cohort study of 40 patients with isolated, operatively treated patella fractures.
  • Functional assessment using SF-36, Knee Injury and Osteoarthritis Outcome Scores (KOOS), physical examination, and Biodex testing.
  • Mean follow-up of 6.5 years.

Main Results:

  • Patients reported significantly lower scores on SF-36 and KOOS compared to population norms.
  • 52% required hardware removal; 38% with retained fixation reported pain.
  • Objective deficits included extensor lag (20%), restricted motion (up to 38%), and significant quadriceps strength deficits (26-31%).

Conclusions:

  • Operative treatment for patella fractures results in persistent symptomatic complaints and functional deficits at midterm follow-up.
  • These findings highlight the complexity of patella fracture treatment and the need for comprehensive patient counseling.
  • The study provides valuable data on long-term functional outcomes, informing surgical decision-making and patient expectations.
