Fractures with complex fracture patterns are associated with increased rate of subsequent conversion to total knee arthroplasty after a tibial plateau fracture: an observational cohort study of 12,012 patients from the Swedish Fracture Register

Fractures with complex fracture patterns, particularly AO/OTA 41B3, 41C2, and 41C3, were associated with an increased TKA conversion rate following TPF. The conversion rate increased with increasing age, but sex and high-energy injury mechanisms did not affect conversion rate. On a national level, 3% of patients were converted to TKA within 5 years of sustaining a TPF, and 4% of patients treated surgically. This may help surgeons when counseling patients with TPFs.
