“…To our best knowledge, similar studies do not exist in literature so far. Regarding the results of postural stability after total knee replacement and the influence of substituting or retaining the posterior cruciate ligament, it could be shown that, similar to the current study, patient regained the status of the nonoperated side independently from the surgical method [20]. Furthermore we could show that, in both groups, the overall postural stability of the operated side reached the level of the nonoperated side.…”

“…The role of the periarticular tissue must be highlighted even in the context of obesity. We could show once more that the increase of BMI inversely correlates with postural stability [20]. However, the relevance of this result remains undetermined.…”

Purpose and Hypothesis. Knee osteoarthritis results, inter alia, in decreased postural stability. After arthroplasty, postural stability recovers, but it is unclear whether this can be ascribed to a reduction of pain or to the preserving of receptor-rich intraarticular soft tissue and natural knee kinematics. The objective of this study was to evaluate whether an unicondylar knee arthroplasty provides better results regarding postural stability or a patient-specific knee spacer. Methods. In this comparative study, we assessed functional results and postural stability 16 months after 20 unicondylar knee arthroplasties (group A) and 20 patient-specific interpositional knee device implantations (group B). Patients were evaluated using the KSS and WOMAC score. Postural stability was analysed during single leg stance on a force platform (Biodex Balance System). Results. Concerning postural stability, range of motion (ROM), and KSS 16 months after the procedure, there were no significant differences between both groups. Conclusion. Successful treatment of knee osteoarthritis restores postural stability to the level of the contralateral side, regardless of the implant device.

“…The analysis of the success of knee arthroplasty using various endoprosthesis designs has been a topic of many examinations that are usually based on the use of subjective tests and the matching of patients with different types of endoprostheses [2,[11][12][13][14][15][16]. In our examination, an objective index of the gait pattern was used after knee arthroplasty in the same patient with, in one knee joint, an implanted endoprosthesis with sacrifice of the posterior cruciate ligament, and in the other, an endoprosthesis with a preserved posterior cruciate ligament.…”

Introduction/Objective. The essence of the treatment of degenerative knee joint diseases is pain relief, restoring motion range and stability of knee joints. Methods. In this study, 35 patients participated after having surgery of the knee joint. The patients had a posterior - stabilized (PS) endoprosthesis in one joint, and a posterior cruciate ligament retaining (CR) endoprosthesis in the other. Kinematic data was collected using a 3D optical system for tracking fluorescent markers in time. Based on these data, the following parameters were determined: degree of flexion, medio - lateral (ML) translation, lateral gap, medial gap and the angle of change between the transtibial and transfemoral axes. Results. The results show a more pronounced flexion degree with the PS prosthesis compared to the CR prosthesis. Also, the results show negligible values of the ML translation, lateral gap and medial gap in both types of prostheses. Using the non-parameter Wilcoxon test, a substantial difference in the angle change between the transtibial and transfemoral axes was confirmed, that is, in the flexion angles on the CR and PS prostheses. Conclusion. This study shows that there is no great difference in the use of the PS or CR designs of endoprostheses. Better behavior and range of motion in the knee joint were established with the implantation of the PS endoprosthesis. This conclusion is confirmed by the substantial difference in the degree of flexion of the knee joint and in the position of the transversal axes of the tibia and femur

“…Cruciate ligaments are indeed crucial for the stabilization and ROM of the knee in three planes. The current literature is still controversial regarding this topic [62], most reviews suggest that no significant differences in outcome exist between PCL retaining and PCL sacrificing techniques [63][64][65][66][67]. However, it is important to note that these studies were not conducted in highly active patients.…”

(1) Background: Improved surgical techniques and implants in total knee arthroplasty (TKA) have led to broader indications for surgical interventions of osteoarthritis of the knee. There is a growing young and active patient subgroup with high return to sports (RTS) expectations after TKA. The current lack of evidence regarding RTS capacity in this patient cohort, requires the consolidation of experts’ opinions and experiences to address the special needs among these patients. The aim of this study was to assess current expert opinions in regard to preoperative patient assessment, surgical technique and decision-making and patient counseling for these patients. (2) Methods: We performed a survey among surgeons specialized in arthroplasty with a questionnaire designed to assess current recommendations, surgical techniques, and implant preferences as well as patient counseling in patients with high expectations for RTS after TKA. (3) Results: The majority of surgeons are in favor of return to low-impact sports after TKA within 3 to 6 months. Some even recommend return to high-impact sports. Despite improvement of surgical techniques and implants, we observed no clear preference for a single surgical technique or implant specification in active patients. (4) Conclusions: Current evidence for sports-associated complications after TKA is scarce. Despite a growing array of surgical techniques and implants, the available literature is still controversial with no single surgical technique or TKA design distinguishing itself clearly from others. Surgeons’ recommendations are mostly based on their experience and training. Nonetheless, we observed growing faith in modern implants with some surgeons even recommending high-impact sports after TKA.

Abstract: In case it is necessary to use a PS implant, no negative influence on postural stability is to be expected compared to a CR implant.
