| description | <h4>Background</h4> <p>Cementless fixation is an alternative to cemented unicompartmental knee replacement (UKR), with several advantages over cementation. </p> <p>This study reports the ten-year survival and seven-year clinical outcome of cementless Oxford unicompartmental knee replacement (OUKR).</p> <h4>Patients and Methods</h4> <p>This prospective study describes the clinical outcome and survival of first 1000 consecutive cementless medial OUKRs implanted at two centres for recommended indications.</p> <h4>Results</h4> <p>The 10-year survival was 97% (CI 95%: 92-100%), with 25 knees being revised. The commonest reason for revision was progression of arthritis laterally, which occurred in 9 knees, followed by primary dislocation of the bearing, which occurred in 6 knees. There were two dislocations secondary to trauma and a ruptured ACL, and two tibial plateau fractures. Although there were no definite cases of aseptic loosening, two early revisions were related to tibial fixation: one for pain and a radiolucent line and one for incomplete seating of the component with a radiolucent line. In four revisions the underlying problem was not certain: two were possibly due patello-femoral degeneration, one possibly tibial component overhang and one for unexplained pain. There were no deep infections. The mean OKS improved from 23 (SD 8) to 42 (SD 7) at a mean follow-up of 7.0 years (p < 0.001). There was no significant difference in survival or clinical outcome between the designer and independent centre.</p> <h4>Conclusions</h4> <p>The cementless OUKR is a safe and reproducible procedure with excellent 10-year survival and clinical results in the hands of both the designer and independent surgeons.</p> |
