Purpose: There have been insufficient data regarding the long‐term results of unrestricted kinematically aligned total knee arthroplasty (unKATKA) in Asian patients. We investigated mid‐ to long‐term clinical and radiological follow‐up data of Korean patients after caliper‐verified unKATKA of minimum 7.4–10 years including categorised data of postoperative tibial component, limb and knee alignment. Additionally, we analysed the preoperative distribution and postoperative restoration of coronal plane alignment of knee (CPAK) phenotypes. Methods: This study is a retrospective analysis of 63 patients: 96 osteoarthritic underwent consecutive caliper‐verified unKATKA between October 2013 and May 2016 by a single surgeon. Implant survivorship was investigated for revision for any reason. Each knee was categorised into an in‐range or outlier group by three postoperative alignment parameters: tibial component, knee and limb alignment. Statistical analyses were done for any significant differences in clinical scores and implant survival rates between groups. Finally, all knees were classified into CPAK classification postoperatively and postoperatively. The CPAK restoration rate was calculated. Results: Among 85 knees in the clinically confirmed group, implant survival was 98.8%. There was one case of revision due to periprosthetic fracture. The percentage postoperatively aligned in the varus (valgus) outlier range was 100% (0%) for tibial component, 16.7% (24.8%) for the knee alignment and 51% (0%) for the limb alignment. All three categories did not affect implant survival or clinical scores. Eighty one out of 96 knees (84.4%) were restored to their CPAK phenotype postoperatively. Conclusion: With the limitation of a case series having a small number of patients and gender deviation, our study suggests that caliper‐verified unKATKA could be a good option regardless of geographical variation of constitutional alignment in patients with osteoarthritis (OA). Level of Evidence: Level IV, therapeutic study. [ABSTRACT FROM AUTHOR]

Background: Diabetic foot (DMF) complications are common and are increasing in incidence. Risk factors related to wound complications are yet to be established after trans-tibial amputation under the diagnosis of DMF infection., Aim: To analyze the prognosis and risk factors related to wound complications after transtibial amputation in patients with diabetes., Methods: This retrospective cohort study included seventy-two patients with DMF complications who underwent transtibial amputation between April 2014 and March 2023. The groups were categorized based on the occurrence of wound complications, and we compared demographic data between the complication group and the non-complication group to analyze risk factors. Moreover, a multivariate logistic regression analysis was performed to identify risk factors., Results: The average follow-up period was 36.2 months. Among the 72 cases, 31 (43.1%) had wound complications. Of these, 12 cases (16.7%) received further treatment, such as debridement, soft tissue stump revision, and re-amputation at the proximal level. In a group that required further management due to wound complications after transtibial amputation, the hemoglobin A1c (HbA1c) level was 9.32, while the other group that did not require any treatment had a 7.54 HbA1c level. The prevalence of a history of kidney transplantation with wound complications after transtibial amputation surgery in DMF patients was significantly greater than in cases without wound complications ( P = 0.02). Other factors did not show significant differences., Conclusion: Approximately 43.1% of the patients with transtibial amputation surgery experienced wound complications, and 16.7% required additional surgical treatment. High HbA1c levels and kidney transplant history are risk factors for postoperative wound complications., Competing Interests: Conflict-of-interest statement: The authors received no financial support for the research, authorship, and/or publication of this article., (©The Author(s) 2024.
