“…12 Carissimia et al reported similar results from a retrospective study of posteromedial OWHTO. 13 Most orthopaedic surgeons believe that HTO has a potential effect on the patellofemoral joint; however, this notion remains somewhat controversial. 11 The extent of that effect has not yet been established.…”

ObjectivePatients who undergo a biplanar ascending medial open‐wedge high tibial osteotomy with an excessive correction angle might experience patella infera and even knee pain after surgery. The purpose of this study was to identify the cut‐off points for the degree of knee varus correction of open‐wedge high tibial osteotomy, which is related to the symptomatic patellar position change.MethodsThis retrospective study included 124 patients (mean age 61.69 ± 6.28 years; 78 women, 46 men) with varying degrees of varus knee osteoarthritis. All patients had undergone standard biplanar medial open‐wedge high tibial osteotomy. They were divided into nine groups according to the change in hip–knee–ankle angle. Plain radiographs and three‐dimensional CT images were obtained preoperatively and 18 months postoperatively. Patellar height was assessed using the Caton–Deschamps index, the Insall–Salvati index, and the Blackburne–Peel index. The patellofemoral index and patellar tilt were used to evaluate the degree of horizontal displacement of the patella. The varus correction, medial–proximal tibial angles, joint line convergence angles, and hip–knee–ankle angles were also measured. The subjective score was evaluated using the Western Ontario and McMaster Universities osteoarthritis index (WOMAC).ResultsThere were significant changes in patella indexes in each group after surgery, among which there was no significant difference in patellar height changes for Groups A to F (p > 0.05), which were significantly lower than those in Group G, H, and I (p < 0.001). The patellar tilt and patellofemoral index also followed the same trend. The improvement in WOMAC scores for Groups G, H, and I was also significantly less for Groups A to F (p < 0.001).ConclusionThe patellar height, patellar tilt, and patellofemoral index all changed significantly in parallel with increasing degrees of osteotomy correction. The cut‐off points for correction angle are 12.5° to 13.4°. When the correction angle is larger than this range, the patellar position can be significantly affected. Postoperative patellofemoral joint pain may be related to the changes in patella position.

“…5 Patellar height disorders result in cartilage degeneration and instability, and the relationship between high tibial osteotomy, meniscal tears, tibia intramedullary nails, and patellofemoral instability has been exclusively investigated in the literature. [6][7][8][9] However, studies on patellar height changes after treatment of plateau fractures are scarce.…”

Objectives: To determine the impact of tibial plateau fractures on patellar height and the factors affecting this impact.Methods: A total of 40 patients treated for plateau fractures between 2017-2021 were evaluated in this retrospective prognostic study. The patient group consisted of lateral radiographs of the operated knees, whereas the control group consisted of lateral radiographs of the healthy sides of the same patients. Insall-Salvati, Caton-Deschamps, Blackburne-Peel, and modified Insall-Salvati indices were measured for both groups. In addition, Schaztker and Luo classifications, as well as the demographic profiles of the patients, were analyzed. Original ArticleResults: There was no significant difference between the groups in terms of patellar height indices )p>0.05(. A significant relationship was found between the Insall-Salvati )p=0.046( and Blackburne-Pell )p=0.011( indices and Luo classification. Post hoc analyses revealed a significant relationship between the Insall-Salvati index and "One Column" fractures and between the Blackburne-Peel index and "Two Column" fractures. Conclusion:Long-term functions of tibial plateau fractures should be evaluated not only with a painless range of motion but also with patellar height. It should be noted that the Luo classification, which evaluates the plateau 3-dimensionally, may be associated with changes in postoperative patellar height values.
