The aim of this study was to carry out a retrospective clinical and radiographical analysis of a consecutive series of a new TKA, and to assess the incidence and distribution of PPRL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective review of all new TKA implants performed by a single surgeon at a single hospital between March 2013 and October 2017 was performed. The minimum follow\u2010up period was 3 months, with ongoing patient review at 6, 12 and 36\u2009months. Sequential post\u2010operative radiographs were performed to determine the presence of PPRL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 122 TKAs were identified in 112 patients over the 4.5\u2010year study period. The average follow\u2010up time was 21\u2009months (range 3\u201351\u2009months). PPRL was noted in 29 TKAs (23.8%). When comparing the PPRL group to those without PPRL, there was a difference in body mass index, with body mass index associated with an increased likelihood of PPRL (<jats:italic>P<\/jats:italic> = 0.003). There was no difference in constraint of implant (<jats:italic>P<\/jats:italic> = 0.818), cement type (<jats:italic>P<\/jats:italic> = 0.340), patella resurfacing (<jats:italic>P<\/jats:italic> = 0.286), age (<jats:italic>P<\/jats:italic> = 0.984) gender (<jats:italic>P<\/jats:italic> = 0.376) or initial mechanical axis deviation (<jats:italic>P<\/jats:italic> = 0.054) between groups. PPRL were most commonly seen in tibial anterior\u2010posterior (AP) zone 1 and zone 2 (96.6%), followed by femoral lateral zone 5 (58.6%), tibia lateral zone 1 (55.2%) and tibial lateral zone 2 (53.2%). No patients have required revision surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A high incidence of early PPRL is seen in patients undergoing primary TKA using a new implant system, mainly involving the tibial component.
