Abstract
BACKGROUND
Open reduction and internal fixation (ORIF) is the traditional surgical treatment for patellar fractures, and unicompartmental knee arthroplasty (UKA), especially Oxford UKA, has been increasingly used in patients with medial knee osteoarthritis (OA). However, the process of choosing treatment for patients with both patellar fractures and anteromedial knee OA remains unclear. We present the case of a patient with a patellar fracture and anteromedial OA.
CASE SUMMARY
We present the case of a 72-year-old woman with a history of bilateral medial compartment OA of the knees and a right Oxford UKA. She also experienced a recent left patellar fracture. ORIF and Oxford UKA were performed in a single stage. The patient showed excellent postoperative clinical results.
CONCLUSION
ORIF and Oxford UKA can be performed simultaneously for patients with patellar fracture and anteromedial OA on the same knee.
Core Tip: The routine treatment method for patellar fractures with knee osteoarthritis (OA) is staged surgery in which the patellar fracture is fixed first, then total knee arthroplasty or unicompartmental knee arthroplasty (UKA) is performed after the patellar fracture heals. We report a case of patellar fracture with anteromedial OA, we performed open reduction and internal fixation combined with Oxford UKA for this patient in a single stage, and she showed excellent postoperative clinical results. For elderly patients, single stage surgery reduces the risk of anesthesia and surgery, followed by less postoperative pain and cost.
