ABSTRACT

Total knee replacement is generally a successful surgery with a low incidence of complications, despite this 20% of patients are not satisfied with the clinical result, probably related to the surgical approach, for this reason we look for less aggressive options for the placement of the prosthesis. Medial parapatellar capsulotomy per se is traumatic, therefore, a viable alternative is to incise through the muscular intervals, and the subvastous approach is the epitome of this decision. Material and methods: The objective of this study was to evaluate the functional results of the subvastous vs medial parapetellar approach in total knee arthroplasty. 64 patients with a diagnosis of primary knee osteoarthritis were included. The patients were evaluated with the Knee Society Score at four weeks and six months. Results: Of the total of 64 patients included in the study, they were divided into two groups. Patients underwent the medial parapatellar approach (group I) with 32 patients and the subvastus approach (group II) with 32 patients. The results showed better evolution in the first four weeks with the subvastus approach, but after the six-month revision the results were very similar. Conclusions: The subvastous approach offers a better initial range of motion and less pain in the first weeks, however the results are similar when compared to the medial parapatellar approach in the medium term.
