The Effect of Partial Lateral Facetectomy of the Patella on the Radiographic and Clinical Outcome of Unresurfaced Patellar-retaining Total Knee Arthroplasty (original) (raw)

Background: Management of patellar maltracking during primary TKA is of considerable importance. Lateral release, which is generally performed for this purpose, is associated with several complications. Objectives: In this study, we aimed to evaluate the role of partial lateral facetectomy in tracking the patella in Total Knee Arthroplasty (TKA). Methods: In a retrospective study, the efficiency of partial lateral facetectomy of the patella in achieving proper tracking of the patella was evaluated in 116 patients who underwent unresurfaced patellar-retaining TKA. The radiographic outcome measures included the patellar tilt and patellar shift. The functional outcome was assessed with Kujala anterior knee pain scale. Results: The Mean±SD age of the patients was 66.3±7.6 years. The mean follow-up of patients was ‎‎20.6±8.9 months. The Mean±SD patellar tilt was ‎‎10.5±7.2‎‎‏°‎‏ before the surgery and ‏‎4.4±5‎‎‏° after ‏the operation ‏‎ (‎P‎<‎‏0.001‏‎). ‎The Mean±SD preoperative patel...
