Aims Nearly 99,000 total knee arthroplasties (TKAs) are performed in UK annually. Despite plenty of research, the satisfaction rate of this surgery is around 80%. One of the important intraoperative factors affecting the outcome is alignment. The relationship between joint obliquity and functional outcomes is not well understood. Therefore, a study is required to investigate and compare the effects of two types of alignment (mechanical and kinematic) on functional outcomes and range of motion. Methods The aim of the study is to compare navigated kinematically aligned TKAs (KA TKAs) with navigated mechanically aligned TKA (MA TKA) in terms of function and ROM. We aim to recruit a total of 96 patients in the trial. The patients will be recruited from clinics of various consultants working in the trust after screening them for eligibility criteria and obtaining their informed consent to participate in this study. Randomization will be done prior to surgery by a software. The primary outcome measure will be the Knee injury and Osteoarthritis Outcome Score The secondary outcome measures include Oxford Knee Score, ROM, EuroQol five-dimension questionnaire, EuroQol visual analogue scale, 12-Item Short-Form Health Survey (SF-12), and Forgotten Joint Score. The scores will be calculated preoperatively and then at six weeks, six months, and one year after surgery. The scores will undergo a statistical analysis. Discussion There is no clear evidence on the best alignment for a knee arthroplasty. This randomized controlled trial will test the null hypothesis that navigated KA TKAs do not perform better than navigated MA TKAs. Cite this article: Bone Jt Open 2021;2(11):945–950.

Abstract Background and Purpose. The primary purpose of this randomized controlled trial was to determine which method of mobilization—(1) standardized exercises (SE) and continuous passive motion (CPM), (2) SE and slider board (SB) therapy, using an inexpensive, nontechnical device that requires minimal knee active range of motion (ROM), or (3) SE alone—achieved the maximum degree of knee ROM in the first 6 months following primary total knee arthroplasty (TKA). The secondary purpose was to compare health-related quality of life among these 3 groups. Subjects. The subjects were 120 patients (n=40/group) who received a TKA at a teaching hospital between June 1997 and July 1998 and who agreed to participate in the study. Methods. Subjects were examined preoperatively, at discharge, and at 3 and 6 months after surgery. The examination consisted of measurement of knee ROM and completion of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Results. The 3 treatment groups were similar with respect to age, sex, and diagnosis at the start of the study. There were no differences in knee ROM or in WOMAC Osteoarthritis Index or SF-36 scores at any of the measurement intervals. The rate of postoperative complications also was not different among the groups. Discussion and Conclusion. When postoperative rehabilitation regimens that focus on early mobilization of the patient are used, adjunct ROM therapies (CPM and SB) that are added to daily SE sessions are not required. Six months after TKA, patients attain a satisfactory level of knee ROM and function.

AbstractThe use of tourniquet in total knee arthroplasty (TKA) had a lot of controversies with no clear agreement about the advantages and disadvantages of tourniquet. This study aims to show the effects of tourniquet use in TKA on the functional and clinical outcomes with follow-up of 5 years. This is a randomized, double-blind, and single-center study of 101 patients who were treated by TKA and divided randomly into two groups. Tourniquet was used in group A and was not used in group B. Both groups were assessed by Knee Society score (KSS), knee injury and osteoarthritis outcome score (KOOS), visual analogue scale (VAS) score for thigh pain, and postoperative complications. Both groups were followed up for 5 years. The group of no tourniquet showed significant better functional outcomes measured by KSS at postoperative periods of 2 weeks (p = 0.001), 6 weeks (p = 0.006), and 3 months (p = 0.034), and KOOS at postoperative periods of 2 weeks (p = 0.001), 6 weeks (p =0.001), and 3 months (p = 0.016). However, there was no significant difference in long-term follow-up of 5 years. There were significantly better results with use of tourniquet regarding surgeon's visualization during surgery, less operative time, and less calculated blood loss, while significantly better results with no use of tourniquet were reported regarding less hospital stay, less postoperative analgesic consumption, and less postoperative thigh pain measured by VAS score at postoperative periods of day 1 (p = 0.001), day 5 (p = 0.001), 2 weeks (p = 0.001), and 6 weeks (p = 0.001). Regarding postoperative blood transfusion and clinical deep venous thrombosis, there was no significant difference between use of tourniquet or not. The evidence presented in this level-1 randomized controlled trial suggests that no use of tourniquet in TKA can improve functional outcomes in early postoperative period with no significant difference on functional outcome at 5 years of follow-up.
