In literature, good outcomes are reported for total knee arthroplasty (TKA) in varus deformity. In this manuscript, the available literature on TKA in varus deformity is analyzed, and the preferred surgical techniques of the authors are described.

2025年3月1日 · The optimal soft tissue release technique for severe varus total knee arthroplasty (TKA) remains controversial. The technique of tibial plateau reduction was suggested for severe varus deformity during TKA. The purpose of this study was to evaluate the clinical and radiological outcomes of the technique of tibial plateau reduction.

Varus knee deformity is the most common deformity in patients who undergo primary TKA. Osteoarthritic varus knees are characterized by cartilage and bone loss in the medial compartment of the knee joint as well as medial contracture and lateral laxity of …

2018年8月23日 · Varus deformity of the knee is the most common angular deformity in total knee arthroplasty (TKA) [1]. It is typically characterized by a mechanical axis of less than 180° at the long-leg x-rays, with a medial joint line narrowing and a proximal tibial deformity.

Knee varus alignment represents a notorious cause of knee osteoarthritis. It can be caused by tibial deformity, combined tibial–femoral deformity and/or ligament imbalance. Understanding malalignment is crucial in total knee arthroplasty to restore ...

Tibial components placed in constitutional or anatomic varus, in an attempt to restore the native oblique joint line along with well-balanced gaps, demonstrated 98% survivorship at five years. Keywords: functional alignment; robotic-assisted TKA; …

2024年11月13日 · For patients with varus KOA, TKA can correct the varus deformity, thereby reducing the load on the medial compartment, improving knee adduction moments, and minimizing lateral trunk movement...

2021年7月8日 · In CPC with marked varus deformity, instability and bone loss, the use of primary TKA is associated with a clinical outcome comparable to standard cases. Ligamentous balancing may be addressed using primary implants and simple cost-effective techniques may be used to manage an extensive bone loss.

2015年1月1日 · Correct ligament balancing in TKA allows for satisfactory knee proprioception, restores proper load transfer and theoretically improves implant survivorship. This chapter describes a stepwise approach to correcting varus and valgus deformity in TKA. When the deformity is fixed and not reducible, correction is more difficult to achieve.

2025年1月1日 · Patient with severe varus deformity (>15⁰) undergoing a functionally aligned TKA achieve a well-balanced TKA with excellent clinical outcomes and small rates of soft tissue release.

2022年6月29日 · Varus deformity is the most frequently seen angular malformation of the knee in total knee arthroplasty (TKA), characterized by a lower extremity load‐bearing alignment transferred to the medial side of the knee center with both bony deformity and soft tissue imbalance. 1 Several intra‐ or extra‐articular factors have been considered as ...

2021年7月14日 · Aseptic tibial loosening is now considered the most common reason that total knee arthroplasties (TKA) fail long term. There are unique subsets of patients that fail into varus alignment of the tibial tray with collapse of the medial proximal tibia.

Varus deformity of the knee is the most common angu-lar deformity in total knee arthroplasty (TKA) [1]. It is typically characterized by a mechanical axis of less than 180° at the long-leg x-rays, with a medial joint line narrowing and a proximal tibial deformity.

2024年5月25日 · Following FA RA-TKR, patients with severe varus deformity achieved a balanced TKA, excellent short-term clinical outcomes and low incidence of soft tissue release comparable to patients with mild varus deformity. Long-term outcomes and longevity studies are still needed with alternative alignment techniques.

2024年9月1日 · In a comparative study of intra-operative soft tissue balance between PS-TKA and CR-TKA using the measured resection technique for varus OA knees, CG generally increases up to 10° flexion and decreases after increasing to 90° in PS-TKA, while CR-TKA tends to stabilize thereafter [35], and varus balance tends to decrease in CR-TKA while ...

2024年12月3日 · TKA Instability is a common cause of early failure following total knee arthroplasty. Diagnosis can be made clinically with presence of a varus/valgus thrust during ambulation, positive posterior sag with the knee flexed to …

Background: The sequential medial release technique including semimembranosus (semiM) release is effective and safe during varus total knee arthroplasty (TKA). However, there are concerns about weakening of knee flexion strength after semiM release.

Targeting residual varus alignment in total knee arthroplasty may be functionally beneficial to preoperative varus patients. Bilateral TKA patients were enrolled. According to the postoperative hip-knee-ankle axis, patients were allocated into residual varus (3° ± 1°) alignment group or neutral (0° ± 1°) alignment group.

2017年11月1日 · In spite of improvements in implant designs and surgical precision, functional outcomes of mechanically aligned total knee arthroplasty (MA TKA) have plateaued. This suggests probable technical intrinsic limitations that few alternate more anatomical recently promoted surgical techniques are trying to solve.

2022年6月3日 · Knee varus alignment represents a notorious cause of knee osteoarthritis. It can be caused by tibial deformity, combined tibial–femoral deformity and/or ligament imbalance. Understanding malalignment is crucial in total knee arthroplasty to restore frontal plane neutral mechanical axis.
