“…Although the survival was similar in the current series of patients with the OSS TM , the followup in the OSS TM series was twice as long. Other studies have noted problems with dislocation of the Endo-Model 1 implant, despite an antidislocation feature [24,35,36]. Femoral-tibial dislocations occurred in two knees in our Endo-Model 1 series whereas none were observed in the current study.…”

“…The second one is a vertical axis corresponding to the hinge post's extension in the tibial baseplate, around which the tibia rotates under the femur. A "post-in-channel" design -where a non-fixed post can slide within the tibial component -allows for joint distraction in flexion that is somewhat limited as a function of the integrity of the periarticular soft tissues [16]. This distraction has two consequences.…”

During total knee replacement, hinged total knee implants are used in cases where ligament balancing cannot be achieved with less-constrained implants. The case of a patient who experienced two episodes of intraprosthetic dislocation of his rotating-hinge total knee prosthesis is described. There are very few reports of this type of dislocation with these implants. The implant's design, particularly of the hinge, plays an important role in stability. The balance between the flexion and extension spaces is very important even when using a hinged total knee implant. The role of the extensor mechanism in anteroposterior stability is reviewed, along with simple ways to augment it.

Revision total knee arthroplasty (TKA) in the setting of major bone deficiency and/or soft tissue laxity might require increasing levels of constraint to restore knee stability. However, increasing the level of constraint not always correlates with mid-to-long-term satisfactory results. Recently, modular components as tantalum cones and titanium sleeves have been introduced to the market with the goal of obtaining better fixation where bone deficiency is an issue; theoretically, satisfactory meta-diaphyseal fixation can reduce the mechanical stress at the level of the joint line, reducing the need for high levels of constraint. This article reviews the recent literature on the surgical management of the unstable TKA with the goal to propose a modern surgical algorithm for adult reconstruction surgeons.
