Introduction:
Comminuted patella fractures comprise 55 % of patellar fractures. In spite of advances in internal fixation of patella, patellectomy remains an effective treatment in comminuted fractures. In the shadow of different efficient methods of internal fixation, little attention is paid to patellectomy as an old treatment in patellar fracture which is a treatment option in circumstances like comminuted fractures and osteomyelitis.
Presentation Of Case:
A 54-year-old male presented with complaint of knee pain and limited range of motion. The patient experienced patella fracture four years ago and several sessions of surgery have been performed on his patella including tension band wiring, partial patellectomy, and arthroscopic release. Lastly, pain and severe limited range of motion, convinced us to perform total patellectomy. The result is satisfactory after one year; flexion is up to 90° and no limping or extension lag is observed. The only complaint is mild anterior knee pain.
Discussion:
Patella has two important biomechanical functions including linking and displacement. Preserving even a single fragment of the patella substantially improves linking and displacement function of the patella. Total patellectomy is reserved for conditions like failed internal fixation, comminuted fractures, and patellar osteomyelitis. Although function of the knee cannot be thoroughly restored after removing of the patella, total patellectomy can lead to a relative satisfaction in performing activities of daily living.
Conclusion:
In spite of various types of treatment for patellar fracture, total patellectomy, is still an efficient treatment option in circumstances like comminuted fractures, failed internal fixation, and osteomyelitis.
