NexGen MIS Tibial Component (Mini-keel) is a tibial component specially developed for minimally invasive surgery in total knee replacement (TKR), and the size limitations of its design and the modular system could affect tibial fixation strength, however, this has not been precisely evaluated thus far. This study aimed to systematically review the literature describing the outcome following TKR with the use of a Mini-keel. Electronic searches of databases were undertaken in July 2019 by two experienced orthopaedic surgeons according to the PRISMA guidelines for literature describing the outcomes of TKR with the use of a Mini-keel. Quality of studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The initial search found a total of 623 studies from all the databases. Seven studies met all the inclusion criteria and were eligible for critical appraisal and quality assessment. In total, 2,198 cases were included in the systematic review. Thirty-five revision cases due to aseptic loosening were found from the systematic review. Two studies were negative about using a Mini-keel and three studies were positive about it, while the other two studies did not judge the quality of a Mini-keel. There have been conflicting conclusions among studies for the use of a Mini-keel. There remains a paucity of prospective cohort studies between TKRs with the use of a Mini-keel and those with the use of a conventional implant, which makes it difficult to determine the usefulness and reliability of this implant.

Abstract Background:Chronic knee pain after a total knee replacement has been estimated to affect 10 to 30% of patients and is related to dissatisfaction with surgery, reduced function and reduced quality of life. Rehabilitation is often prescribed in the subacute period post-operatively, but it may offer benefit to the increasing numbers of patients with chronic pain after their knee replacement. The aim of this systematic review is to evaluate the effectiveness of rehabilitation to improve pain, function and quality of life in people with chronic knee pain persisting for more than 3 months following a total knee replacement.Methods: The systematic review was conducted following PRISMA guidelines with a search of the online databases Ovid Medline, Embase via Ovid, CINAHL Plus, PsycINFO, Ovid Emcare and Proquest from their earliest date to July 12, 2020. The search criteria included English language randomised controlled trials of rehabilitation strategies in any setting to treat people with chronic knee pain, defined as knee pain persisting for more than 3 months, following a total knee replacement. Rehabilitation programs included exercise therapy, patient education, cognitive and mind-body strategies and self-management and excluded medication trials, procedural techniques and complementary therapies. Results:There were 254 abstracts screened for eligibility with 13 remaining for full-text screening. Following full-text screening, there were no studies that met the eligibility criteria for evaluating rehabilitation therapy to treat chronic knee pain persisting for more than 3 months following a total knee replacement.Conclusion:Despite the high volume of knee replacement surgery and the high incidence of moderate to severe chronic pain ensuing, there is currently no evidence available that rehabilitation commencing three months after surgery can effectively treat chronic pain and disability following a total knee replacement.

SummaryObjectives: This study investigated cemented fixation of the tibial component from a canine total knee replacement preclinical model. The objective was to determine the local morphology at the material interfaces (implant, cement, bone) and the local relative micro-motion due to functional loading following in vivo service.Methods: Five skeletally mature research dogs underwent unilateral total knee replacement using a cemented implant system with a polyethylene (PE) monobloc tibial component. Use of the implanted limb was assessed by pressure-sensitive walkway analysis. At 60 weeks post-surgery, the animals were euthanatized and the tibia sectioned en bloc in the sagittal plane to create medial and lateral specimens. High resolution imaging was used to quantify the morphology under the tray and along the keel. Specimens were loaded to 50% body weight and micro-motions at the PE-cement and cement-bone interfaces were quantified.Results: There was significantly (p = 0.002) more cement-bone apposition and interdigitation along the central keel compared to the regions under the tray. Cavitary defects were associated with the perimeters of the implant (60 ± 25%). Interdigitation fraction was negatively correlated with cavitary defect fraction, cement crack fraction, and total micro-motion.Clinical significance: Achieving good inter-digitation of cement into subchondral bone beneath the tibial tray is associated with improved interface morphology and reduced micro-motion; features that could result in a reduced incidence of aseptic loosening. Multiple drill holes distributed over the cut tibial surface and adequate pressurization of the cement into the subchondral bone should improve fixation and reduce interface micro-motion and cavitary defects.

This study aims to determine the effect of counseling on quality of life and self-care agency for patients who are scheduled for total knee replacement (TKR). The study has a quantitative and quasi-experimental design with a control group. The patients in the control group ( n = 40) received routine care. Face-to-face and telephone counseling was offered to individuals in the intervention group ( n = 39). The data was collected at face-to-face interviews by using a patient characteristics form, Quality of Life Scale, and Self-Care Agency Scale. The scores for quality of life and self-care agency in the 6th to 8th and 14th to 16th weeks after surgery were very significantly higher in the intervention group than in the control group ( p < .001). This study shows that counseling given by the nurse increases the quality of life and self-care agency of patients undergoing TKR.
