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 .
Squatting Following Total Knee Arthroplasty
& NA ; This prospect i ve study was performed to investigate whether postoperative alternate flexion and extension splinting ( daily change in position of immobilization by splinting ) was useful in restoring full range of motion ( ROM )  after total knee arthroplasty as compared with continuous passive motion . The  alternate flexion and extension splinting group and the  continuous passive motion group were each composed of 34 knees .  Final ROM was measured at an average of 3.5 years postoperatively . Squatting was possible in 31 knees ( 45.6 % ) of the alternate flexion and extension  splinting group . The postoperative ROM of the osteoarthritic knees ( 131.8 ° ± 12.3 ° ) was significantly greater than that of the rheumatoid knees ( 121.9 ° ± 22.4 ° ) ( p < 0.05 ) . The postoperative ROM of the alternate flexion and extension splinting group ( 135.1 ° ± 11.9 ° ) also was significantly greater than that of the continuous passive motion group ( 120.0 ° ± 19.7 ° ) ( p < 0.01 ) . There was no statistically significant relationship between the posterior slope of tibial cutting and the postoperative ROM . It is suggested that alternate flexion and extension splinting is effective in restoring full ROM after total knee arthroplasty
