“…In this study, we found that the aHKA of knees graded as K–L 3–4 was smaller than 2°, compared with that of K–L 0–2; this result may verify the aforementioned hypothesis. It is also worth mentioning that we found a mean JLCA of 2.4° in normal individuals, which is much larger than that reported in previous studies 1 , 29 . Further studies are required to evaluate the clinical significance of these findings.…”

Background: Few studies have reported the coronal constitutional alignment of the lower limbs in mainland China. This study aimed to analyse the distribution of the coronal plane alignment of the knee (CPAK) classification in the osteoarthritic and healthy Chinese populations. Materials and Methods: The CPAK distributions of 246 patients (477 knees) with osteoarthritis (OA) and 107 healthy individuals (214 knees) were retrospectively examined using long-leg radiographs. Radiological measurements and CPAK classification of different Kellgren–Lawrence grades in patients with unilateral total knee arthroplasty (TKA) were compared. The clinical outcomes of patients with CPAK type I who underwent mechanical alignment or restricted kinematic alignment during TKA were examined. Results: The most common distributions in the OA and healthy groups were type I and type II, respectively. In patients who underwent unilateral TKA, the most common distribution of knees graded as Kellgren–Lawrence 3–4 was type I. However, the most common distributions of contralateral knees graded as Grade 0–2 were type I and II. For patients with CPAK type I, the mechanical alignment and restricted kinematic alignment groups did not differ significantly concerning postoperative clinical outcomes at three months. Conclusion: The most common distributions in Chinese osteoarthritic and healthy populations were types I and II, respectively. In addition, OA progression may lead to changes in the CPAK classification.
