Abstract

PURPOSE: To present the results of mdivastus and paramedian approach for total knee replacement arthroplasty (TKA).
MATERIALS AND METHODS
Thirty two patients having bilateral total knee replacement arthroplasty were randomized prospectively-one knee having a vastus muscle-splitting approach(MVS) and the other knee having a median parapatellar approach(MPP)- to compare the difference in lateral release, operation time, postoperative ROM and drain amount, HSS score, return to SLR and extension lag at 2 weeks in TKA.
RESULTS
The MVS approach offered an early advantages compared with MPP approach, especially in terms of lateral release[22(68.7%)on MPP and 5 15.6%) on MVS (p=0.014)], ROM at postoperative 2 week (p=0.043) and early return to SLR (p=0.023). There were no significant differences in operation time, postoperative ROM and drain amount, HSS score and extension lag.
CONCLUSION
The MVS approach has the potential to improves the rapid restoration of quadriceps mus-cle control and to lead to reduction in the need for lateral release in TKA.
