Duracon CS Lipped Extra Small Tibial Insert

The Duracon@CS (Condylar Stabilizing) Lipped Extra Small Tibial Insert is intended to be used with Duracon@Extra Small Universal and Cruciform tibial baseplates, Durac.on@ Cruciate Retaining femoral components and Duraconm patellar components as part of a total knee system in primary cemented total knee arthroplasty. These inserts are intended to be used in cases where there is destruction of the joint surfaces with or without bone deformity, where the cruciate ligaments are inadequate, not present, or cannot be preserved during the operative procedure, especially when anterior-posterior stability is impaired due to absence of the patella. The collateral ligaments should be intact if this insert is utilized. This tibial insert may also be used in situations where the posterior cruciate ligament is present - its geometry will accommodate that ligament. More specific indications and contraindications are listed below:

Indications

Noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis or avascular necrosis,

Rheumatoid arthritis,

Correction of functional deformity,

Post-traumatic loss of joint anatomy, particularly when there is patello-femoral erosion, dysfunction or prior patellectomy; and,

Irreparable Eracture of the knee

Absolute contraindications include:

Overt infection,

Distant foci of infections (which may cause hematogenous spread to the implant site),

Rapid disease progression as manifested by joint destruction or bone absorption apparent on roentgenogram,

Skeletally immature patients

Cases where there is poor bone stock which would make the procedure unjustifiable,

Conditions presenting an increased risk of failure include:

Uncooperative patient or patient with neurological disorders who is incapable of following instructions,

Osteoporosis,

Metabolic disorders which may impair bone formation,

Osteomalacia, and

Previous arthrodesis
