..Caution should be taken by surgeons to avoid revolutionary approaches with existing implants, because they harbor a risk of catastrophic failure...

..The results of this study suggest that minimally invasive total knee arthroplasty offers superior short-term as well as possible long-term results...

..An orthosis that utilizes the principles of static progressive stretch may be a successful treatment for improving the range of motion and satisfaction of patients who have knee contractures...

..The authors believe static progressive stretching devices may be an effective method for increasing the ranges of motion and satisfaction levels of patients who develop arthrofibrosis after total knee arthroplasty...

..LEVEL OF EVIDENCE: Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence...

..The purpose of this study was to compare the early clinical outcomes of these two approaches...

..Understanding the benefits and drawbacks of each approach as well as the reported results will aid orthopaedic surgeons in selecting the best treatment option for their patients...

..If notch stenosis is identified, arthroscopic débridement usually leads to a satisfactory result, at least at short-term follow-up...

..Knee Society scores were lower in the surviving high-BMI knees. All surviving components were radiographically stable. The results suggest that UKA should be approached with caution in patients who have high BMIs...

..Despite the low complication rate, this study yielded insights into further potential improvements in using this MIS technique for TKAs...

..Although further study is necessary, we believe that this technique might reduce postoperative complications and improve clinical outcomes of total hip arthroplasty...

..Our data demonstrate no distinct advantage of navigation when combined with a minimally invasive approach. LEVEL OF EVIDENCE: Level II, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence...

..8 N), and the anchors locked consistently. This direct insertion technique saves time and procedural steps over traditional anchor insertion techniques while using an allograft anchor that reincorporates into host bone...

..The keys to long-term survival of both fixed and mobile-bearing designs in unicompartmental knee arthroplasty are patient selection, surgical technique, and surgical experience...

..Violation of the extensor mechanism is minimized and soft-tissue balancing is enhanced with the suspended technique...

..Radiographic analysis did not reveal any progressive radiolucencies. These results suggest that excellent long-term outcomes can be achieved with minimally invasive total knee arthroplasty...

..Both technologies have led manufacturers to invest more effort into newer prosthetic instrumentations and designs to facilitate these techniques...

..Thus, further refinements are needed to increase clinical success and allow this technique for general use...

..At 12 weeks follow-up, there was no difference in mean Knee Society objective and functional scores. In summary, in this study, minimal incision total knee arthroplasty demonstrated no improvement over a standard approach...

..Long-term outcomes of both techniques will need to be investigated...

..Level of Evidence: Therapeutic study, level IV (retrospective case series). See the Guidelines for Authors for a complete description of levels of evidence...

..These changes require well-designed clinical studies to further document their effectiveness...
