The Outcomes of Isolated Distal Realignment Procedures in Patellofemoral Instability: A Systematic Review and Meta-analysis

“…20 Both groups also had similar knee osteoarthritis outcome score, Kujala's score, and pain and incidence of work change. 20 Radiographically, the patellar height and the evaluation of tibiofemoral and patellofemoral osteoarthritis were also similar amongst the two groups. 20 These similarly suggest that the addition of proximal realignment procedures do not significantly alter the outcomes of distal realignment procedures postoperatively.…”

“…20 When compar-ing between the distal realignment and combined group, Vivod et al found that there was no significant difference with regards to the proportions of postoperative patellofemoral dislocations, centralization of the patella, apprehension test, and increased lateral patellar motion. 20 Both groups also had similar knee osteoarthritis outcome score, Kujala's score, and pain and incidence of work change. 20 Radiographically, the patellar height and the evaluation of tibiofemoral and patellofemoral osteoarthritis were also similar amongst the two groups.…”

“…14 Two other studies have also compared between distal realignment procedures with or without additional proximal realignment procedures. 20,21 However, these studies were not included in the review because even the group without the additional proximal realignment procedures had other proximal realignment procedures. 20,21 Vivod et al compared between isolated proximal realignment procedures, isolated distal realignment procedures, and combined procedures.…”
