Possible indications for a rotating hinge or pure hinge implant in primary total knee arthroplasty (TKA) include collateral ligament insufficiency, severe varus or valgus deformity (> 20°) with relevant soft-tissue release, relevant bone loss, including insertions of collateral ligaments, gross flexion-extension gap imbalance, ankylosis and ...

The NexGen Rotating Hinge Knee (RH Knee) is designed for revision, difficult primary, and limb salvage surgeries in patients with significant bone loss and/or ligament deficiencies

A hinged knee replacement is a complex knee replacement that requires a special implant with either a hinge or a rotating platform. During a knee replacement surgery, the surgeon removed …

Hinged implants are the most constrained knee replacement prostheses. They are very useful in complex cases of total knee arthroplasty (TKA) revision. Hinged implants have evolved with rotating bearings and modularity that allows local joint ...

Rotating hinge knee prostheses are typically used in revision and severe primary total knee arthroplasty (TKA). For these challenging patient groups, currently only few studies with mid- or even long-term follow-up and adequate patient numbers are ...

2024年9月21日 · Hinged implants are increasingly used in complex rTKA cases involving substantial instability and bone loss, which compromise the performance and longevity of standard implant designs [60]. The three most commonly reported indications for considering hinged-implants in rTKA are infection, instability, and aseptic loosening.

Rotating hinge knee prostheses (with or without distal femoral replacement) are indicated in cases of unreconstructible bony or soft tissue compromise. Despite their versatility, these implants have demonstrated high rates of mechanical failure. We aimed to review clinical outcomes of a novel hinged knee arthroplasty system.

2021年1月1日 · Rotating hinge implants are commonly used in revision total knee arthroplasty (TKA) in the setting of significant ligamentous instability or bone deficiency. These highly constrained implants have been associated with variable clinical outcomes and uncertain long-term survivorship.

2021年5月20日 · In complex primary and revision total knee arthroplasty (TKA), rotating-hinge TKA (RH-TKA) prostheses play an important role. Compared to early fixed-hinge knee designs, new implants that include rotating platforms and improved hinge constructs may offer improvements in both survival and clinical ou …

2022年6月4日 · Rotating hinge knee is the best option in selected difficult case scenarios. With long-term success of TKA for long-term functional results, indications are getting extended for more complex situations in primary and revision conditions.
