To our knowledge, there is no published data of the role of the four pegged cruciate retaining design for treatment of valgus knee arthritis. This study evaluates the survivorship and outcomes of a lowprofile four-peg tibial base plate without intra-medullary extension in TKA for the valgus knee. Methods After Institutional review board approval, a retrospective analysis of all total knee replacements performed by from January 2001 and December 2004 yielded 38 patients (29 females with 30 TKAs and 9 males with 9 TKAs) who had 39 Total Knee Arthroplasties (TKA) with preoperative valgus deformity greater than 10 degrees. These patients were implanted with the Zimmer Nex Gencruciate retaining total knee with a four pegged tibial base plate and followed for an average of 68 months (52-98 months). Exclusion criteria included patients who underwent revision TKA or were under the age of 18. The mean age and standard deviation at the time of surgery for the entire cohort was 67 ± 13 years (27 to 89 years). The preoperative diagnosis for 36 patients was osteoarthritis and for 2 patients rheumatoid arthritis. The youngest patients in our cohort had a preoperative diagnosis of rheumatoid arthritis. Two senior surgeons performed a standard medial parapatellar arthrotomy on all study patients. All surgical operative notes were reviewed to determine surgical approach and ligamentous release. For
