Background: The outcome for TKA (total knee arthroplasty) upon whether the posterior cruciate ligament is preserved with cruciate retaining (CR) prostheses or sacrificed with posterior stabilized (PS) prostheses are still debated between studies. Materials and Methods: We included a total of 144 knees operated with cemented fixed bearing primary CR or PS TKAs. Independent t-tests were conducted for the outcomes and possible confounding variables between groups where relevant, with analyses using Chi-squared tests for nominal data. Results: Operation on patients with age of lower than 65 years predicts increased intraoperative bleeding volume (p = 0.037), pre-operative range of motion (ROM) of less than 90 degrees was a predictor for better improved post-operative ROM (p 0.001) and PS prostheses is superior to CR in terms of ROM improvement (p = 0.04), however with both groups achieving similar maximum ROM (p = 0.308). Conclusion: Improvement of ROM is increased by the use of PS prostheses compared to CS prostheses, with pre-operative ROM as a possible confounding factor and the maximum ROM achieved for both prostheses being similar. Lower age of the operation is also related to increased intraoperative bleeding

Abstract Background: Posterior cruciate ligament (PCL) avulsion fracture of tibia is an uncommon but serious complication during primary cruciate retaining total knee arthroplasty (TKA). The first objective of this report was to conduct a retrospective cohort study to investigate the incidence and potential risk factors of PCL avulsion fracture in primary cruciate-retaining TKA. The second objective was to assess the functional outcomes of the knee after reduction of PCL avulsion fracture.Methods: From January 2014 to January 2016, 56 patients who experienced PCL avulsion fracture of tibia in primary cruciate-retaining TKA were included in study group. Patients in this group underwent reduction of avulsion fracture. In this period, we selected 224 patients (control group) for comparison. Patients in this group also underwent the same TKA but no PCL avulsion fracture occurred. Range of motion of the knee and Knee Society Scores were assessed. The forgotten joint score was used to analyze the ability to forget the joint. Differences were considered statistically significant at p < 0.05.Results: In our series, the incidence of PCL avulsion fracture was 4.6%. There was no significant differences (p > 0.05) with regard to preoperative or postoperative range of motion of the knee, final 4 year mean clinical score in study and control groups 92.4 ± 2.7 and 93.6 ± 1.9, respectively, and mean functional scores of 85.1 ± 1.8 and 87.1 ± 1.2, respectively.Conclusions: The incidence of PCL avulsion fracture of tibia is relatively high. Older age and female gender were two risk factors of fracture in primary cruciate-retaining TKA. Reduction of PCL avulsion fracture with high-strength line can achieve good stability and function of the knee.

<p class="abstract"><strong>Background:</strong> Total knee arthroplasty has got excellent results.

AbstractBoth from the perspective of the individual and from a socioeconomic point of view (e.g., return to work), it is important to have an insight into the potential differences in recovery between posterior cruciate ligament retaining (PCR) and posterior stabilized (PS) total knee arthroplasty (TKA) implants. The primary aim of this study was to compare the speed of recovery of patient-reported outcome between patients with a PCR and PS TKA during the first postoperative year. The secondary aim was to compare the effect on range of motion (ROM). In a randomized, double-blind, controlled, single-center trial, 120 adults diagnosed with osteoarthritis of the knee were randomized into either the PCR or PS group. Primary outcome was speed of recovery of patient-reported pain and function, measured with the Western Ontario and McMaster Universities osteoarthritis index (WOMAC), with a follow-up of 1 year. Main secondary outcome measure was ROM. A generalized estimating equations (GEE) analysis was used to assess whether there was a difference over time between groups (“p-value for interaction”). Between 2008 and 2011, 59 participants received a PCR TKA (mean age, 70.3 years [SD = 7.7]; mean body mass index [BMI], 30.5 kg/m2 [SD = 5.4]) and 55 participants a PS TKA (mean age, 73.5 years [SD = 7.0]; mean BMI, 29.2 kg/m2 [SD = 4.4]). Six patients (two PCR and four PS) were excluded because of early drop-out, so 114 patients (95%) were available for analysis. In between group difference for total WOMAC score was −1.3 (95% confidence interval [CI]: −5.6 to 3.1); p-value for interaction was 0.698. For ROM, in between group difference was 1.1 (95% CI: −2.6 to 4.7); p-value for interaction was 0.379. These results demonstrated that there are no differences in speed of recovery of WOMAC or ROM during the first postoperative year after PCR or PS TKA.
