Conclusions Although total reoperation rates did not differ in the two population s , reoperation for bearing dislocation was more likely to occur in Asian than in Western patients , whereas reoperation for lateral knee OA progression was more likely to occur in Western than in Asian patients after Oxford Phase III UKA .
Background Implant survivorship is reported to be lower and complications , particularly bearing dislocation , are reported to be more frequent in Asian than in Western patients with medial knee osteoarthritis ( OA ) undergoing Oxford ® Phase III unicompartmental knee arthroplasty ( UKA ) .
To date , however , these complications have not been compared between these groups of patients .
Questions / purpose s The purpose of this study was to perform a meta- analysis comparing the st and ardized incidence rates of ( 1 ) all-cause reoperation ; ( 2 ) reoperation related to bearing dislocation ; and ( 3 ) reoperation related to progression of lateral compartment arthritis in Asian and Western patients with medial knee OA who underwent Oxford Phase III UKA .
Minimally invasive Oxford medial unicompartmental knee arthroplasty. A note of caution!
We present the peak outcome results of the Oxford medial unicompartmental arthroplasty through a minimally invasive surgical incision . This prospect i ve study included 78 Oxford medial unicompartmental knee replacements in 68 patients . At the 2 year review the patients achieved a mean Oxford Knee Score of 38.3 . This was not significantly different to the 2 year results of the phase 2 Oxford knee carried out using a st and ard parapatellar approach when patients achieved a mean OKS of 36.0 . Four unicompartmental knee replacements required revision for unexplained pain , deep infection , aseptic loosening and bearing dislocation .  Minimally invasive joint replacement is attractive to both patients and surgeons , but is technically dem and ing with complications inherent to limited access
