A patellectomy or hemipatellectomy is a surgical procedure involving the complete or partial removal of the patella, commonly known as the kneecap. This procedure is typically indicated for patients suffering from conditions such as non-healing injuries, recurrent dislocations, or severe arthritis affecting the patella, which can lead to significant pain and functional impairment. The patella plays a crucial role in knee mechanics, and its removal may be necessary to alleviate pain and restore mobility. During the procedure, a vertical incision is made over the patella, allowing the surgeon to access the underlying soft tissues. The surgeon carefully dissects these tissues to expose the patella for examination. If the decision is made to proceed with the removal, the muscle and tendon attachments to the patella are severed, enabling the complete or partial excision of the kneecap. In cases where only a portion of the patella is removed, the remaining part is smoothed using a motorized shaver to ensure proper healing and function. The quadriceps tendon and patellar tendon, which are essential for knee extension, are then reattached to the remaining patellar structure or sutured together if the patella is entirely excised. Finally, the soft tissues and skin are meticulously closed in layers to promote optimal recovery.
