The aim of this studythe early results of total knee arthroplasty (TKA)through minimally invasivemidvastus approach.Methods: This prospective study included 100 knee joints (43 females, 57 males; mean age61.3years) whounder went total knee arthroplasty forgrade 4 knee osteoarthritis.AllTKA operations were performed by the single orthopaedic surgeon through the minimally invasive midvastusapproach.Pre-operatively, all patients had primary osteoarthritis.In all cases,aPScemented prosthesis with modular insertwasused.All the knees were assessed according to theKneeSociety kneeand functions cores before surgery and atthefinal follow-up.Postoperative radiographic evaluations were performed on AP and lateral radiographs according to the knee society scoreevaluation and scoring system. The mean follow-up period was 6 months (range 3 to 12months).
Results:The mean KSS score significantly improved from27.8±11.0 preoperatively to 92.2±3.8 post-operatively(p=0.000).The improvement in the knee functions core was from 54.223±23.43 to 94.07±7.720(p=0.000).The mean improvement in the KSS clinical and functions cores were 64.4 and39. 8points, respectively. The mean knee ROM significantly increased from 56.2±22.7°pre-operatively to 111.0±9.9°postoperatively (p=0.000). Patients had nopatellar trackingabnormalityintraoperatively;thus,there was none ed for lateral retinacular release.Postoperative clinical and radio graphicassessments showed no signs of instability or loosing. There were no changes in tracking and loosing of the implant during the follow up period. Neurovascular injury did not occur.
Conclusion:In our study,lateral retinacular release was not doneduetoachievement of proper patellar tracking in TKA with minimally invasive midvastus approach and showing satisfactory clinical and radiographic results
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
