Gap balanced adjusted mechanical alignment versus measured resection mechanical alignment: a randomised controlled trial. [PDF]

Arch Orthop Trauma Surg, 2023
Abstract Introduction Alignment goals in total knee replacement (TKR) is a topical subject. This study compares the short-term functional outcomes and patient reported outcome measures (PROMs) of two philosophies for knee arthroplasty alignment: measured resection (MR) and an individualised alignment philosophy, with the

An early clinical comparative study on total knee arthroplasty with kinematic alignment using specific instruments versus mechanical alignment in varus knees [PDF]

Frontiers in Surgery, 2023
BackgroundThe kinematic alignment technique, as one of the alignment options for total knee arthroplasty, has attracted increasing attention from orthopedic surgeons and has been increasingly performed in the most populous countries in the world.

Kinematic alignment versus mechanical alignment in total knee arthroplasty: An up-to-date meta-analysis

Journal of Orthopaedic Surgery, 2022
Purpose The purpose of this meta-analysis was to compare the efficacy and imaging parameters of kinematic alignment (KA) and mechanical alignment (MA) in total knee arthroplasty (TKA) and to evaluate whether patients undergoing KA-TKA benefited more than

Addressing sagittal plane imbalance in primary total knee arthroplasty: functional alignment outperforms kinematic and mechanical alignment techniques [PDF]

Bone & Joint Open
Aims: Sagittal plane imbalance (SPI), or asymmetry between extension and flexion gaps, is an important issue in total knee arthroplasty (TKA). The purpose of this study was to compare SPI between kinematic alignment (KA), mechanical alignment (MA), and ...

The Use of Navigation During Total Knee Replacement Improves Precision in Achieving Mechanical Alignment in Obese Patients [PDF]

JBJS Open Access
Background:. Obesity (body mass index ≥30 kg/m2) is a global health challenge and a known risk factor of knee osteoarthritis (KOA), increasing the need for total knee arthroplasty (TKA).

Clinical outcomes of restricted kinematic alignment versus mechanical alignment in total knee arthroplasty: a meta-analysis of randomized controlled trials [PDF]

BMC Musculoskeletal Disorders
Background Restricted Kinematic Alignment (rKA) is a well-established technique for total knee arthroplasty (TKA) that aims to approximate natural knee motion within defined safety boundaries.

Cyclic mechanical stretch contributes to network development of osteocyte-like cells with morphological change and autophagy promotion but without preferential cell alignment in rat

Biochemistry and Biophysics Reports, 2017
Osteocytes play important roles in controlling bone quality as well as preferential alignment of biological apatite c-axis/collagen fibers. However, the relationship between osteocytes and mechanical stress remains unclear due to the difficulty of three ...

Mismatch between femur and tibia coronal alignment in the knee joint: classification of five lower limb types according to femoral and tibial mechanical alignment

BMC Musculoskeletal Disorders, 2018
Background Reasons for dissatisfaction with total knee arthroplasty (TKA) include unequal flexion or extension gap, soft tissue imbalance, and patella maltracking, which often occur with mismatch between femoral and tibial coronal bony alignment in the ...

Change in mechanical axis alignment highly correlates with increased limb loading after total knee arthroplasty

Orthopaedic Journal of Sports Medicine, 2017
Aims and Objectives: Mechanical axis of the lower limb assessed in standing long-leg radiographs was demonstrated to change within the first three postoperative months after total knee arthroplasty (TKA).
