Summary
Mechanical alignment (MA) in total knee arthroplasty (TKA) is being questioned due to patient dissatisfaction. This review challenges 10 flawed MA principles, advocating for personalized TKA techniques to improve outcomes.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Mechanical alignment (MA) has been a cornerstone of total knee arthroplasty (TKA) since 1973.
- Advances in surgical techniques, implants, and understanding of knee biomechanics necessitate re-evaluation of MA principles.
Conclusions:
- Certain established MA principles in TKA may be erroneous or unfounded.
- Personalized TKA, considering individual patient anatomy and kinematics, offers a rational alternative.
- Transitioning to personalized TKA is crucial for enhancing patient satisfaction and functional recovery.

2.5K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

01:18Errors in Taping

Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...
