Coronal plane stability before and after total knee arthroplasty.

Effect of medial epicondylar osteotomy on soft tissue balancing in total knee arthroplasty.

Balancing and surgical exposure of a severe varus knee during total knee arthroplasty (TKA) can be difficult. Use of a medial epicondylar osteotomy to solve these problems has been reported. This study compared knee stability in cadaveric specimens after TKA, after medial epicondylar osteotomy, and after conventional subperiosteal release of the medial collateral ligament (MCL). Five cadaveric ...

Effect of polyethylene component thickness on range of motion and stability in primary total knee arthroplasty.

Total knee arthroplasty (TKA) is a common procedure with good survivorship and functional results. Optimal results are dependent on proper osseous cuts and soft tissue balancing. Soft tissue tensioning via the polyethylene spacer thickness is an important component of soft tissue balancing. Increased thickness increases soft tissue tension and, therefore, has the potential to increase stability...

Reliability of the hip-to-ankle radiograph in determining the knee and implant alignment after total knee arthroplasty.

Hip-to-ankle radiographs have been used to evaluate lower limb alignment before and after total knee arthroplasty. However, earlier studies have inappropriately used correlation to assess the reproducibility of the radiographs. We determined the reliability of the hip-to-ankle radiograph using the Bland-Altman analysis. Two consecutive hip-to-ankle radiographs were obtained in 52 patients (52 k...

The impact of surgical technique on coronal plane motion in total knee arthroplasty

The current role of coronal plane alignment in Total Knee Arthroplasty in a preoperative varus aligned population: an evidence based review.

BACKGROUND Based on historical data, the current standard of care in Total Knee Arthroplasty (TKA) is to restore the overall alignment to a neutral mechanical axis of 0°±3° or even slight valgus. However, there is significant controversy in literature regarding intentionally placing the TKA in the patient's physiologic, rather than neutral (0±3°), mechanical alignment. QUESTIONS/PURPOSES The ...
