Event Description

The literature article entitled ¿metaphyseal sleeves in revision total knee arthroplasty: minimum seven-year follow-up study¿, written by sanjeev agarwal, et al.Published in the knee 25 (2018) 1299-1307, https://doi.Org/10.1016/j.Knee.2018.09.010, was reviewed.The purpose of the article was to report early results with the use of metal, porous coated metaphyseal sleeves in revision knee replacements.The authors present seven years of follow-up of the initial cohort.This is, as of yet, the longest follow-up report in literature.Products used: pfc & tc3, depuy.Index revision indications (figure 1): aseptic loosening.Infection.Stiffness (four of these patients were revised to a noiles, depuy and underwent manipulations under anesthesia with continued restricted flexion); one patient was in her mid-40¿s during index revision and had two further re-revisions for stiffness (these will be combined together due to insufficient information regarding the revisions), developed late infection four years after third revision and recently, in her mid-50¿s opted for a two-stage arthrodesis-it is reasonable to conclude that this late infection four years after the last revision was not related to the implant.Pain.Instability.Re-revision indications (figure 1): aseptic loosening (one patient revised for loosening had disengagement at the stem sleeve junction secondary to a technical error of tight fit of stem in femoral diaphysis).Infection (two-stage procedure, transfemoral amputation, distal femoral replacement prosthesis used for reconstruction, antibiotic suppression therapy).Persistent pain.Instability.Other notes: *figure 3 reports migration of the tibial component (radiographic images) *table 1 shows degree of bone loss in femur and tibia.*the discussion section mentions multiple further procedures including amputation.*the article does not discuss patellar resurfacing or cement manufacturer.
