Mini-midvastus versus medial parapatellar approach in total knee arthroplasty: difference in patient-reported outcomes measured with the Forgotten Joint Score

Abstract Background: Low knee awareness after minimally invasive total knee arthroplasty (TKA) has become the ultimate target of a natural feeling knee that meet patient expectations. The objective of this research was to compare the clinical outcomes of TKA via the mini-midvastus (MMV) approach or medial parapatellar (MPP) approach and expound which approach can acquire better quality of life after surgery.Methods: From January 2015 to December 2016, a retrospective cohort study was conducted in 330 patients who underwent TKA via mini-midvastus (MMV) approach were included in MMV group. In this period, we selected 330 patients who underwent TKA via medial parapatellar (MPP) approach (MPP group) for comparison. Clinical results were assessed with visual analogue score for pain (VAS), range of motion (ROM), Knee Society Score (KSS). The forgotten joint score (FJS) was used to analyze the ability to forget the joint.Results: There were significant differences with regard to VAS, ROM and KSS score until six months after surgery between the MMV and MPP group (p < 0.05), but the differences were not found at 12 months, 24 months and 36 months after surgery. However, there were significant differences with regard to FJS score between the groups during the follow up time (p < 0.05).Conclusion: When forgetting the artificial joint after TKA is the ultimate target, better quality of life can be acquired by performing TKA via the MMV approach. In addition, compared with MPP approach, the MMV approach could offer less pain and faster recovery.

Abstract Background The purpose of this study was to determine the mid-term clinical, radiographic and health-related quality of life (HRQoL) outcomes and define the survival rate in patients who had undergone revision total knee arthroplasty (TKA) using the single rotating hinged knee (RHK) design. Methods Between January 2004 and December 2013, 125 revision TKAs were performed at our institution using the single RHK implant. We conducted both a retrospective analysis of prospectively collected outcome data of these patients and a prospective follow-up study of all 39 living patients (41 knees). The follow-up phase included an optional extra follow-up visit, PROM questionnaires, and plain radiographs. Results The ten-year Kaplan-Meier survival rate of the revision RHK knees was 81.7% (95% CI 71.9–91.6%) with re-revision for any reason as the endpoint. Overall, 15 knees (12% of the total) underwent re-revision surgery during the follow-up. The median follow-up was 6.2 years (range, 0–12.7 years) post-operatively for the baseline group. One mechanical hinge mechanism-related failure occurred without any history of trauma or infection. At the time of the final follow-up, the majority of patients evinced a fairly good clinical outcome measured with patient-reported outcome measures and none of the components were radiographically loose. Conclusion We found that in patients undergoing complex revision TKA, fairly good functional outcome and quality of life can be achieved using an RHK implant. Further, it seems that in this type of patient cohort, revision TKA using an RHK implant relieves pain more than it improves ability to function. The NexGen® RHK design can be regarded as a suitable option in complex revision TKA.

Abstract Background: To identify patients’ self-reported health-related quality of life (HRQoL) before and after total knee arthroplasty (TKA) and determine factors contributing to any heterogeneity in HRQoL. Methods: This prospective multicentre study included 404 patients with knee osteoarthritis who underwent TKA between 1 April and 30 December 2019 and in whom HRQoL was assessed preoperatively and at 7 days and 1, 3, and 6 months postoperatively. Sociodemographic characteristics were assessed using a general information questionnaire; disability, using the Knee Injury and Osteoarthritis Outcome Score; pain, using the visual analogue scale (VAS) score; and HRQoL, using the European Quality of Life Five Dimension Five Level (EQ-5D-5L) score. Potential heterogeneity and factors influencing longitudinal changes in HRQoL were analysed using a growth mixture model.Results: The mean EQ-5D-5L score improved from 0.69 preoperatively to 0.90 at 6 months postoperatively. Two types of longitudinal heterogeneity were identified: (1) a group of patients with a small and slow improvement in HRQoL and (2) a group of patients who showed marked and rapid improvement in HRQoL. The main characteristics of the latter group were a monthly family income >2000 yuan, exercising for approximately 30 min daily, and better knee function at baseline. Baseline knee function and change in knee function were significantly associated with the percentage change in HRQoL.Conclusions: HRQoL improved considerably after TKA. However, there was some heterogeneity in the changes in HRQoL depending on certain patient characteristics. Targeted interventions should focus on these differences to optimise the outcomes of TKA.
