“…The majority of patients undergoing TKA have excellent clinical results [14,18,19,21]. A minority of patients may experience knee pain, stiffness, and/or patellar instability One or more of the authors (CH, KLG) have received funding that is not related to the content of this manuscript.…”

“…Some authors have suggested that rotational malalignment of the femoral and/or tibial components causes these problems, and because of this belief, malrotation is a major cause of revision TKA [4,21]. Others have written that rotational component alignment can cause rotational knee instability and even posterior dislocations of the knee after TKA [1,17].…”

Background Rotational malalignment of total knee arthroplasty (TKA) has been correlated with patellofemoral maltracking, knee instability, and stiffness. CT is the most accurate method to assess rotational alignment of prosthetic components after TKA, but inter-and intraobserver reliability of CT scans for this use has not been well documented. Questions/purposes The objective of this study was to determine the inter-and intraobserver reliability and the repeatability of the measurement of TKA component rotation using two-dimensional CT scans. Methods Fifty-two CT scans of TKAs being evaluated for revision surgery were measured by three different physicians. An orthopaedic resident and attending measured the same scans twice (more than 2 weeks apart) and a musculoskeletal radiologist measured them once. To assess interobserver reliability, intraclass correlation coefficients (ICCs) with two-way mixed-effects analysis of variance models as well as 95% confidence intervals for each were done. The repeatability coefficient was calculated as well, which is defined as the difference in measurements that include 95% of the values. This indicates the magnitude of variability among measurements in the same scale, which in this study is degrees. Results The interobserver ICC measurement for the femoral component was 0.386 (poor), and it was 0.670 (good) for the tibial component. The interobserver ICC for the combined rotation measurements was 0.617 (good). The intraobserver ICC for the femoral component was 0.606 (good), and it was 0.809 (very good) for the tibial component. The intraobserver ICC for combined rotation was 0.751 (good). The intraobserver repeatability coefficient for the femoral component was 0.49°, 10.64°for the tibial component, and 12.29°for combined rotation. Conclusions In this study, the inter-and intraobserver reliability, and the repeatability, of TKA component rotation were variable. This raises concern about whether CT scan is diagnostic in the assessment of component malrotation after TKA.

“…Although most patients experience relief of pain and improved function and quality of life [15,26,39,54], various suboptimal outcomes do occur, ranging from mild anterior knee pain to failures requiring revision surgery [5,38]. Patients with these suboptimal outcomes often report excessive joint stiffness or looseness [8,43], limited ROM [41], and difficulty with activities of daily living, such as climbing stairs and walking [10].…”

Major joint arthroplasty is undoubtedly one of the surgical success stories of modern times.The first attempt of treating patients affected by knee osteoarthritis with arthroplasty goes back to the midnineteenth century.In 1880 the German surgeon Themistocles Gluck implanted the first primitive hinge joints made of ivory.The first part of the twentieth century saw the return of interpositional arthroplasty with the use of autologous tissues or metallic surfaces.In the early 1960s, John Charnley's cemented metal-on-polyethylene total hip arthroplasty inspired the development of the modern total knee replacement.He worked on the design of an implant that resurfaced the distal femur and proximal tibia without any direct mechanical link between the components began at the end of the sixties.Technological developments in the field of knee replacement continue to increase the range of solutions for the recovery of joint mobility of painful knee arthritis.
