“…More sensitive outcome scores are needed. Gait analysis could provide more objective parameters, such as measurements of sagittal plane kinematics and kinetics (Börjesson et al 2005, Catani et al 2012). …”

Background and purposeThere is no consensus regarding the clinical relevance of gender-speciﬁc prostheses in total knee arthroplasty (TKA). We summarize the current best evidence in a comparison of clinical and radiographic outcomes between gender-speciﬁc prostheses and standard unisex prostheses in female patients.MethodsWe used the PubMed, Embase, Cochrane, Science Citation Index, and Scopus databases. We included randomized controlled trials published up to January 2013 that compared gender-speciﬁc prostheses with standard unisex prostheses in female patients who underwent primary TKAs.Results6 trials involving 423 patients with 846 knee joints met the inclusion criteria. No statistically significant differences were observed between the 2 designs regarding pain, range of motion (ROM), knee scores, satisfaction, preference, complications, and radiographic results. The gender-specific design (Gender Solutions; Zimmer Inc, Warsaw, Indiana) reduced the prevalence of overhang. However, it had less overall coverage of the femoral condyles compared to the unisex group. In fact, the femoral prosthesis in the standard unisex group matched better than that in the gender-speciﬁc group.InterpretationGender-speciﬁc prostheses do not appear to confer any beneﬁt in terms of clinician- and patient-reported outcomes for the female knee.

“…54 Furthermore, very small differences were found between the two designs on gait analysis. 55 With respect to patients' perceptions of UKAs, Bhattacharya et al noted that 83.5% of patients with fixed-bearing UKAs were satisfied compared with 93.9% of those with mobile-bearing UKAs. 56 Lateral versus Medial UKA…”

Unicompartmental Knee Arthroplasty: The Past, Current Controversies, and Future Perspectives

et al. 2018

Unicompartmental knee arthroplasty (UKA) is a bone conserving and ligament-sparing procedure that reliably restores normal knee kinematics and function for arthritis limited either to the medial or the lateral compartment of the knee. Although there is enough evidence to demonstrate that the UKA offers good medium to long-term success given the correct patient selection, prosthesis design, and implantation technique, there are several reports to suggest inferior survival rates in comparison with the total knee arthroplasty (TKA). Furthermore, it is a specialized procedure which works well in the hands of the experienced operator and therefore different authors' tend to draw different conclusions based on the same evidence, and as a result, there is great variability in the usage of the UKA. The aim of this current concept's review is to present to the readers the history of the UKA especially with reference to implant design, discuss current controversies, and outline the future perspectives of this novel procedure.

“…Earlier research found that total knee arthroplasty (TKA) influences gait parameters [3,5,6,12,27,29,37,38,40] and the variability and stability of gait [14,31,41] 1 year after surgery. The measurement of gait patterns provides valuable information; however, it ignores the variability involved in the completion of the gait.…”
