Proximal tibiofibular dislocation in closing-wedge high tibial osteotomy increases the risk of medium and long-term total knee replacement. Background: High tibial osteotomy is an effective treatment for medial osteoarthritis in young patients with varus knee. The lateral closing-wedge high tibial osteotomy (CWHTO) may be managed with tibiofibular dislocation (TFJD) or a fibular head osteotomy (FHO). TFJD may lead to lateral knee instability and thereby affect mid- and long-term outcomes. It also brings the osteotomy survival rate down. Objective: To compare the CWHTO survival rate in function of tibiofibular joint management with TFJD or FHO, and to determine whether medium and long-term clinical outcomes are different between the two procedures. Material & Methods: A retrospective cohort study was carried out that included CWHTO performed between January 2005 to December 2018. Those patients were placed in either group 1 (FHO) or Group 2 (TFJD). Full-leg weight-bearing radiographs were studied preoperatively, one year after surgery and at final follow-up to assess the femorotibial angle (FTA). The Rosenberg view was used to assess the Ahlbäck grade. The Knee Society Score (KSS) was used to assess clinical outcomes and a Likert scale for patient satisfaction. The total knee replacement (TKR) was considered the end of the follow-up and the point was to analyze the CWHTO survival rate. A sub-analysis of both cohorts was performed in patients who had not been FTA overcorrected after surgery (postoperative FTA ≤ 180°, continuous loading in varus). Results: A total of 230 knees were analyzed. The follow-up period ranged from 24–180 months. Group 1 (FHO) consisted of 105 knees and group 2 (TFJD) had 125. No preoperative differences were observed in terms of age, gender, the KSS, FTA or the Ahlbäck scale; neither were there any differences relative to postop complications. The final follow-up FTA was 178.7° (SD 4.9) in group 1 and 179.5° (SD 4.2) in group 2 (p = 0.11). The Ahlbäck was 2.21 (SD 0.5) in group 1 and 2.55 (SD 0.5) in group 2 (p = 0.02) at the final follow-up. The final KSS knee values were similar for group 1 (86.5 ± 15.9) and group 2 (84.3 ± 15.8). Although a non-significant trend of decreased HTO survival in the TFJD group was found (p = 0.06) in the sub-analysis of non-overcorrected knees, which consisted of 52 patients from group 1 (FHO) and 58 from group 2 (TFJD), 12.8% of the patients required TKR with a mean of 88.8 months in group 1 compared to 26.8% with a mean of 54.9 months in the case of group 2 (p = 0.005). However, there were no differences in clinical and radiological outcomes. Conclusion: TFJD associated with CWHTO shows an increase in the conversion to TKR at medium and long-term follow-up with lower osteotomy survival than the CWHTO associated with FHO, especially in patients with a postoperative FTA ≤ 180° (non-overcorrected). There were no differences in clinical, radiological or satisfaction results in patients who did not require TKR. Level of evidence III. Retrospective cohort study.

Abstract Background High tibial osteotomy (HTO) has been used for over 60 years in clinical practice and mainly comprises two major techniques: closed wedge high tibial osteotomy (CWHTO) and open wedge high tibial osteotomy (OWHTO). However, these have been gradually replaced by total knee arthroplasty (TKA), due to inconsistent clinical results and many complications. With the concept of knee-protection and ladder treatment of osteoarthritis, as an effective minimally invasive treatment for knee osteoarthritis, HTO has once again received attention. Methods A systematic literature search was conducted in PubMed, Embase, ClinicalKey, CNKI, and the China Wanfang database. The search terms relating to osteoarthritis and high tibial osteotomy were used. Studies were considered eligible if the participants were adults with knee osteoarthritis (KOA) who had undergone HTO. A total of two reviewers participated in the selection of the studies. Reviewer 1 was assigned to screen titles and abstracts, and reviewer 2 to screen full-text data. Data extraction was completed by reviewer 2, and 30% were checked by the research team. Potential conflicts were resolved through discussion. The methodological quality was assessed using a risk of bias, based on the Cochrane handbook and Newcastle-Ottawa assessment scale. The outcome indicators are (1) posterior slope of tibial plateau, (2) the height of the patella, (3) fracture in the osteotomy plane, (4) survival rate, (5) special surgery knee score (HSS), and (6) the recurrence of varus deformity of the included studies were evaluated according to the guidelines of the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) working group (Atkins et al., BMJ 328:1490, 2004). Results Among the 18 articles included, 10 were prospective cohort studies, five were randomized controlled trial (RCT) studies, one was prospective comparative study (PCS), one was retrospective comparative study (RCS), and one was retrospective cohort. The earliest publication year was 1999, and the most recent was 2018. A total of 6555 eligible cases were included, comprised of 3351 OWHTO patients and 3204 CWHTO patients. Five RCT were assessed using risk of bias, based on the Cochrane handbook. Eleven cohort studies and two case-control studies were assessed using the Newcastle-Ottawa assessment scale. These six outcome indicators for a total of twenty-four evidence individuals were evaluated separately, among which the GRADE classification of 1, 2, and 6 was medium quality, and 3, 4, and 5 were low quality. Based on our systematic review, regardless of whether the chosen procedure was OWHTO or CWHTO, both HSS scores increased significantly as compared with the preoperative scores. Compared with CWHTO, the height of the patella and tibial posterior slope angle increased following OWHTO. Additionally, OWHTO has a better long-term survival rate and lower fracture rate, supporting OWHTO as the first treatment choice. Conclusions For young patients with knee osteoarthritis (KOA), high tibial osteotomy (HTO) can be considered as a treatment option to replace total knee arthroplasty (TKA) to reduce the economic burden and promote the reasonable allocation of medical resources. This study shows that compared with CWHTO, OWHTO has certain advantages in long-term survival rate and lower fracture rate, but the level of evidence is lower. In the future, we will need larger sample sizes and longer follow-up randomized controlled trials to improve our research.

Background: To determine whether a proximal tibiofibular joint dislocation (TFJD) increases lateral compartment gapping more than a fibular head osteotomy (FHO) during a closing-wedge high tibial osteotomy (CWHTO). The second objective was to determine whether lateral compartment gapping affects clinical outcomes. Methods: A prospective randomized clinical study was carried out that included 18 patients in Group 1 (FHO) and 18 in Group 2 (TFJD). Varus-stress radiographs of all the patients with both knees at full extension and at 30° of flexion were studied pre-operatively and 12 months post-operatively. Lateral compartment gapping was measured in millimeters. The Knee Society Score (KSS) was used to assess clinical stability. Results: The difference between the pre- and post-operative measurements relative to gapping in the lateral knee compartment at 0° of knee flexion was 1.3 mm (SD 1.8) in Group 1 and 4.5 mm (SD 2.4) in Group 2 (p = 0.006). At 30° of knee flexion, this difference was 1.9 mm (SD 1.2) in Group 1 and 5.2 mm (SD 3.1) in Group 2 (p = 0.01). No differences were observed in the pre- and post-operative period relative to gapping in healthy knees. Pre-operatively, both groups presented similar KSS knee values: Group 1 with 54.7 (SD 11.7), Group 2 with 54.8 (SD 11.1) (n.s.). Post-operatively, these values were also similar: Group 1 with 93.2 (SD 7.4), Group 2 with 93.5 (SD 5.5) (n.s.). Conclusions: In patients who have undergone a CWHTO, TFJ dislocation increases knee lateral compartment gapping when compared to an FHO at 0° and 30° of knee flexion. However, this fact seems to have no repercussion on the functional status of the knees as measured with the KSS at the one-year follow-up.

Aims and Objectives: To date there exists no golden standard of treatment of late periprosthetic joint infection. Different forms of treatment comprise single-stage or two-stage or multiple revisions. Respectively, mid- to long-term results are rare. Materials and Methods: We retrospectively analysed 66 patients with septic total knee arthroplasty treated by two different therapy algorithms: Until 2009 patients were treated routinely by implant removal and implantation of an articulating spacer in combination with at least 6 weeks of antibiotic administration. After an antibiotic-free period of two weeks persistent infection was ruled out by punctation. In case of negative antimicrobial cultures after another 14 days patients were treated by reimplantation (n=36, group 1). After 2009 persistent infection was ruled out by open revision and change of the articulating spacer instead of a punctuation. In case of negative antimicrobial cultures after another 14 days patients were treated by reimplantation (n=30, group 2). After a follow-up of 61 months (group 1), respectively 36 months (group 2), patients and their family doctors were contacted by phone concerning the survival rate of the new implant. Results: In group 1 persistent infection was ruled out in every patient by punctuation. During reimplantation tissue samples of 8 patients (22%) showed positive microbiological results again, within 4 patients with a change of the underlying bacteria. After a follow-up of 61 months 31 patients showed no signs of reinfection of their implant and were not operatively revised (86%). In group 2 all patients were treated with open revision and change of the articulating spacer for at least once. 8 patients showed a change of the underlying bacteria during these procedures. During reimplantation tissue samples of 8 patients (27%) showed positive microbiological results again. After a follow-up of 36 months 27 patients showed no signs of reinfection of their implant and were not operatively revised (90%). The difference between both groups was not significant (p>0.05). Concerning the overall complication rate no significant differences between both groups could be found (p>0.05). Conclusion: Concerning reinfection rate we could not detect significant differences between both groups. Patients of group 2 were treated operatively significantly more often and showed a significantly more frequent change of the underlying bacteria. If these results are confirmed in big cohort studies the elaborate treatment algorithm of open revision and change of the articulating spacer might become dispensable.

Objective – to compare the results and complications of open wedge high tibial osteotomy (OWHTO) in patients operated on according to the standard technique and using the developed method of performing the operation using the original fixator.Materials and methods. 73 patients with primary and secondary OA of the knee I–III stages were recruited into the study, which were divided into 2 groups. Group 1 consisted of 43 patients, who underwent 46 OWHTO from 2005 to 2019 using the standard technique using short plates with a fixed spacer (Puddu I (5 times) and II generation (24 times), Osteomed (17 times)) and bone grafting. Group 2 consisted of 30 patients who were operated on in 2018– 2020 using the developed surgical technique and the original fixator. To assess the result, we studied the change in pain according to the Visual Analog Scale (VAS), as well as the functional (FS) and objective scores (OS) of the knee according to the Knee Society Score (KSS) before surgery, after 3 months and 1 year after OWHTO.Results. In group 1, one year after OWHTO, the results were obtained: excellent in 43.5% of cases, good – in 41.0% and satisfactory – in 15.2% of patients. In group 2, an excellent result was obtained in 59.3% of patients, good – in 33.4% and satisfactory – in 7.3% of cases. In group 1, 15 (32.7%) patients were diagnosed with 26 complications, and in group 2 – 5 (16.6%) patients with 5 complications.Conclusions. The use of the developed surgical technique and the original fixator made it possible to increase the percentage of excellent and good treatment results from 84.5% to 92.7% and to reduce the number of complications associated with OWHTO from 32.7% to 16.6%.
