AbstractOrthopaedic surgeons commonly have the misconception that patients with tibial plateau fractures will likely go on to posttraumatic knee arthritis requiring total knee arthroplasty (TKA). In younger patients, osteochondral allograft (OCA) transplantation is an alternative method to address posttraumatic knee arthritis. The purpose of this study was (1) to identify our institutional failure rate following tibial plateau open reduction and internal fixation (ORIF) (failure was defined as conversion to TKA or OCA); (2) to determine if there are patient- or injury-related risk factors predictive of failure; and (3) to characterize differences between patients treated with TKA versus those treated with OCA transplantation. A 10-year retrospective review was conducted to identify patients treated at our institution with a tibial plateau fracture. Patients included in the final analysis were at least 18 years of age with an articular fracture (AO/OTA 41 B/C). The primary outcome was subsequent ipsilateral OCA or TKA. There were 350 patients (359 tibial plateau fractures) with a mean follow-up of 22.3 months (range, 6-133 months) who met inclusion criteria. Twenty-seven fractures (7.5%) were subsequently converted to a TKA or OCA at an average of 3.75 ± 3.1 years following their initial surgery. Patients who consumed tobacco were 2.3 times more likely to require a joint replacement (confidence interval [CI], 1.0-5.2; p = 0.04). Those patients who received an OCAs were significantly younger as compared with their TKA peers, both at time of initial injury (37 vs. 51 years, p = 0.02) and at time of surgery (41 vs. 55 years, p = 0.009). The joint replacement rate in this study is similar to those studies in the published literature that focused solely on the prevalence of conventional TKA. Tobacco is a risk factor for failure following tibial plateau ORIF. Patients who were treated with an OCA were younger at time of injury and failure.Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
