Leg Length Discrepancy in a Patient with Ipsilateral Total Knee and Total Hip Arthroplasty

Despite concerted intraoperative attempts to establish equal limb alignment, leg length discrepancy (LLD) remains a frequent complication following elective total hip arthroplasty (THA) [1]. A number of effective intraoperative imaging and clinical limb length techniques have been recommended to minimize this complication; however, all of these assessment modalities have their reported limitations [2,3]. Moreover, the multifactorial nature of the issue of equal leg length has impeded the development of a consensus among hip arthroplasty surgeons on how to best avoid LLD. We report an unusual case which exemplifies the complexity of this problem in an adult male with ipsilateral total knee arthroplasty (TKA) who experienced LLD following primary THA despite the utilization of recommended imaging and clinical techniques to circumvent this problem.
