The coronal plane high tibial osteotomy. Part II: a comparison of axial rotation with the opening wedge high tibial osteotomy.

ABSTRACT: The amount of axial rotation in the tibia caused by high tibial osteotomy is relatively unknown. The authors hypothesize that the coronal plane high tibial osteotomy, a novel technique used to treat varus malalignment, alters the axial rotation of the tibia less than the opening wedge high tibial osteotomy. Eight, embalmed, stripped cadaveric tibia-fibula constructs with intact interosseous membranes were randomized to either opening wedge or coronal plane high tibial osteotomies. Sequential valgus corrections of 5 degrees, 10 degrees, and 15 degrees were performed. The Qualisys Track Manager motion capture system was used to measure axial rotation. Student's t test was used to compare axial rotation between the two groups. A p value of 0.05 was determined to be significant. The coronal plane technique produced rotations about the tibial axis that were statistically significantly smaller than those of the opening wedge technique for all correction angles (1.2 degrees internal rotation (IR) vs 16 degrees external rotation (ER), respectively, at 5 degrees correction; p = 0.02) (3.5 degrees IR vs 21.2 degrees ER at 10 degrees correction; p = 0.04) (4.5 degrees IR vs 23.0 degrees ER at 15 degrees correction; p = 0.01). The coronal plane high tibial osteotomy alters axial rotation of the tibia significantly less than the opening wedge high tibial osteotomy.

Project description:Purpose:To evaluate the short-term clinical outcomes, complications, hospitalization time, and readmission rate related to day-case opening wedge high tibial osteotomy (OWHTO) with intraosseous PEEK (polyether ether ketone) implant, in the treatment of knee osteoarthritis. Methods:An observational study on patients treated with OWHTO using intraosseous PEEK implant was performed with a period of 12 months follow-up. Grade of Knee Injury and Osteoarthritis Outcome Score (KOOS) was assessed preoperatively, at 6 months, and at 12 months postoperatively. A simple t test was used to analyze the outcomes. P values <.05 were considered significant. Complications and revision surgeries were registered. Results:In the period from 2016 to 2017, a consecutive group of 40 patients (13 female, 27 male) with symptomatic medial knee osteoarthritis and varus malalignment were included in the study. The average age of the patients was 54.9 (± 7.6) years. In total, 30 (77%) patients met the criterion for minimal clinically important difference in KOOS scores. The KOOS symptoms improved from 58.1 ± 20 to 78.5 ± 16.5 (P < .0001), pain from 48.1 ± 18.2 to 78.6 ± 18.5 (P < .0001), activities of daily living from 59.0 ± 19.5 to 84.1 ± 15.2 (P < .0001), sport from 23.2 ± 17.6 to 55.6 ± 26.3 (P < .0001), and quality of life from 28.4 ± 12.8 to 61.5 ± 22.5 (P < .0001) at 1-year follow-up. The average hospitalization time at the Day Surgery Unit was 5.6 ± 0.7 hours, and 4 (10%) patients had to be readmitted to the hospital within 2 weeks postoperatively. The overall complication rate was 18%. Complications that required revision surgery were registered in 4 patients (10%), including 2 non-unions and 2 progressions of osteoarthritis. Conclusions:The day-case OWHTO with intraosseous PEEK implant was a success in 77% of the cases. The results and complications were comparable with other published studies. Despite a short hospitalization time, the readmission rate was low. Level of Evidence:IV, therapeutic case series.
