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

2020 unpublished
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 minimidvastus (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

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.
