Is Minimally Invasive Surgery in Total Knee Arthroplasty Really Minimally Invasive Surgery?

Does Minimally Invasive Surgery Improve Short-term Recovery in Total Knee Arthroplasty?

“…In a comparative study, one interesting finding was worse responses from patients undergoing MIS regarding sinking and curling of scar edges [14]. Niki et al [34] reported the degree of muscle damage was equivalent between MIS TKA and conventional TKA by measuring postoperative serum levels of various muscle-related enzymes. Surgeons should reconsider what is meant by the term minimally invasive to the knees during TKA.…”

Comparison of Minimally Invasive Direct Anterior Versus Posterior Total Hip Arthroplasty Based on Inflammation and Muscle Damage Markers

“…This technique has been used to compare minimally invasive surgery and standard posterior approaches for total hip arthroplasty, with minimal differences reported [10][11][12] . Recently, similar methods were used to analyze total knee arthroplasties, and few differences in the increases in cytokine levels were found with various approaches 13 . The authors of that study stressed the importance of having a clear measureable outcome to define surgery as minimally invasive.…”

“…A rise in the serum creatine kinase (CK) level after trauma, exercise, or surgery has been shown to directly correlate with muscle damage [14][15][16][17] . An analysis using the limited data available on the rise and variability in CK levels after total hip arthroplasty revealed the need for a sample size of fifty-eight patients to detect a difference between the two groups 12,13,18 . Because of the limited data set, we confirmed the results of the power analysis using C-reactive protein (CRP) levels after total hip arthroplasty, which have been better characterized over the last twenty years 13,19,20 .…”

Because of the limited data set, we confirmed the results of the power analysis using C-reactive protein (CRP) levels after total hip arthroplasty, which have been better characterized over the last twenty years 13,19,20 . This showed that a study size of fifty-six patients was needed to detect a 25% difference between the two groups.…”

Early Loosening after Total Knee Arthroplasty with Minimal Incision Surgery: A Report of Two Cases and A Review of the Literature

“…While there is evidence of some short-term benefits after MIS-TKA when conducted by experienced surgeons, there is concern that about a possible increase in complications as use of the MIS technique becomes more wide spread [13,14,[16][17][18][19]. Serious early complications have occurred even for leading surgeons, including vascular injury, patellar tendon injury, condyle fracture, and wound necrosis [14,20].…”
