Objective: To examine the clinical outcome of minisubvastus approach, a true quadriceps-sparing approach for minimally invasive knee arthroplasty.
Material And Method: Between January 2005 and January 2008, 398 knees were included in this study. We evaluated the results of primary total knee arthroplasties performed with minisubvastus approach in patients at a minimum 1-year follow-up period. A retrospective review of the patient medical records was used.
Results: The mean wound length was 11 centimeters and mean blood loss was about 478 milliliters. An average total operative time was 112 minutes. The mean femorotibial angle was corrected from 8 degrees varus preoperatively to 4 degrees valgus postoperatively. Pain assessed by WOMAC score was much improved as the mean score decreased from 50.84 at preoperative to 26.81 at one-year postoperative period.
Conclusion: Minisubvastus arthroplasty is effective and can be performed in almost of knee deformities.

Article Synopsis
- Knee osteoarthritis (OA) often affects obese individuals, and total knee arthroplasty (TKA) is a treatment option that faces challenges in this population; the study explores the effectiveness of robotic-assisted TKA using the mini-subvastus approach for these patients.
- The research involved 114 obese patients, assessing outcomes like pain reduction and knee function improvements post-surgery, with significant results indicating lower pain levels and higher knee scores after three and six months.
- The findings suggest that this surgical method not only minimizes complications and enhances recovery time but also leads to an exceptional range of motion for the majority of patients within six months following the procedure.

Introduction: The successful management of wound healing after total knee arthroplasty (TKA) depends on several aspects of ancillary intraoperative techniques and surgical variables. Many of these have been evaluated in a few recent reports. The prior reviews studied many aspects of wound healing and, for example, found lower risks of wound complications with barbed sutures compared with interrupted closure with non-barbed sutures, no differences in wound complications between adhesives, subcuticular sutures, staples, glue, or mesh adhesives for the closure of the skin layer, and that mesh adhesives may be associated with faster closing times compared to subcuticular sutures or staples in TKA.

Objective: Minimal invasive approach has been increasingly used in total knee arthroplasty (TKA) and more is expected of early rehabilitation in terms of pain release and recovery of knee function. The approach type is one of the major factors that determines the early rehabilitation after TKA. The purpose of this study is to determine whether mini-subvastus approach (MSVA) is superior to the traditional medial parapatellar approach (MPA) in TKA.

Introduction: Alternatives to the classical medial parapatellar (MPP) approach for total knee arthroplasty (TKA) include the mini-medial parapatellar (MMPP), mini-subvastus (MSV), mini-midvastus (MMV) and quadriceps-sparing (QS) approaches. The best approach has been not fully clarified. The purpose of the present study was to conduct a Bayesian network meta-analysis comparing these approaches.
