“…In this case, the impact of the diaphyseal deformity on the knee must be known in order to adjust the surgical planning. Severe FBow is uncommon, although it is predominant in some ethnic populations, such as Asian and Middle Eastern populations (mean FBow angle varying between 1.8° and 5.3°), [13][14][15]24,25 where the FBow angle can reach 88% of the patients in an osteoarthritic population. Interest in the impact of the FBow measurement remains crucial in a worldwide population to manage constitutional diaphyseal deformity and post-traumatic deformity.…”

“…12 This seems even more crucial for patients with severe femoral bowing in the coronal plane, which is the most common constitutional diaphyseal femoral deformity, mainly in Middle Eastern or Asian populations. [13][14][15] Therefore, this radiological study aimed to 1) determine a method assessing the impact of the diaphyseal femoral deformity on lower limb alignment for the varus knee (on full-leg radiograph), 2) to evaluate the reliability and the reproducibility of this method in a large cohort of patients, and 3) to determine the main anatomical factors influencing the lower limb alignment and the mechanical femoral axis. We hypothesized that the impact of the diaphyseal femoral deformity (according to its localization and severity) on the knee alignment could be determined with a simple, reliable, and reproducible method for each patient on standard full-length radiographs.…”

AimsThe impact of a diaphyseal femoral deformity on knee alignment varies according to its severity and localization. The aims of this study were to determine a method of assessing the impact of diaphyseal femoral deformities on knee alignment for the varus knee, and to evaluate the reliability and the reproducibility of this method in a large cohort of osteoarthritic patients.MethodsAll patients who underwent a knee arthroplasty from 2019 to 2021 were included. Exclusion criteria were genu valgus, flexion contracture (> 5°), previous femoral osteotomy or fracture, total hip arthroplasty, and femoral rotational disorder. A total of 205 patients met the inclusion criteria. The mean age was 62.2 years (SD 8.4). The mean BMI was 33.1 kg/m2 (SD 5.5). The radiological measurements were performed twice by two independent reviewers, and included hip knee ankle (HKA) angle, mechanical medial distal femoral angle (mMDFA), anatomical medial distal femoral angle (aMDFA), femoral neck shaft angle (NSA), femoral bowing angle (FBow), the distance between the knee centre and the top of the FBow (DK), and the angle representing the FBow impact on the knee (C’KS angle).ResultsThe FBow impact on the mMDFA can be measured by the C’KS angle. The C’KS angle took the localization (length DK) and the importance (FBow angle) of the FBow into consideration. The mean FBow angle was 4.4° (SD 2.4; 0 to 12.5). The mean C’KS angle was 1.8° (SD 1.1; 0 to 5.8). Overall, 84 knees (41%) had a severe FBow (> 5°). The radiological measurements showed very good to excellent intraobserver and interobserver agreements. The C’KS increased significantly when the length DK decreased and the FBow angle increased (p < 0.001).ConclusionThe impact of the diaphyseal femoral deformity on the mechanical femoral axis is measured by the C’KS angle, a reliable and reproducible measurement.Cite this article: Bone Jt Open 2023;4(4):262–272.

Background: Primary osteoarthritis of knee is one of the most common degenerative conditions associated with disability. With more of varus knee medial compartment osteoarthritis is most common and early presentation. High tibial osteotomy (HTO) is technically demanding and associated with major complication like neurovascular injury, iatrogenic fracture, nonunion. Practically HTO is associated with longer bed immobilization and difficult to take bilateral condition.Methods: We treated 38 patients 54 knees with proximal fibular osteotomy for primary medial compartment osteoarthritis excluding other condition like secondary and inflammatory from January 2017 to December 2017. Pre operative assessment of patients done on standing antero-posterior (AP) X-ray and knee injury and osteoarthritis outcome score (KOOS). Post operative assessment done on opening of medial joint line space on standing AP X-ray and KOOS score.Results: Patients treated with PFO, there was change in the weight bearing axis, opening of the medial joint space, improvement in pain, functional outcome assesses with improvement in KOOS score. 8 patients experienced some catchy knee pain and swelling and deterioration of KOOS score.Conclusions: PFO is simple, cost effective and can be surgical treatment option for primary medial compartment Osteoarthritis irrespective of age, though a greater number of patients with longer follow is needed, initial results are very promising in majority of patients and few patients shows deterioration in comparison to initial results but overall patient’s satisfaction index is good.

Background: The purpose of this study was to compare the improvement of knee function in patients with knee osteoarthritis who underwent total knee arthroplasty and arthroscopy in China, and to provide a scientific basis for the application of clinical total knee arthroplasty in knee osteoarthritis.Methods: A total of 160 patients with knee osteoarthritis who were admitted to Chinese hospital from January 2017 to December 2018 were studied. They were divided into experimental group and control group according to their willingness of treatment. The control group was treated with arthroscopy and the experimental group was treated with total knee arthroplasty. All patients were followed for a period of 6 months. The knee joint function score (HSS), visual analog scale (VAS), and anxiety self-assessment scale (SAS) scores before and after surgery were compared between the two groups. Results: The proportion of "excellent or good" in the efficacy of the experimental group (91.25%) was higher than that of the control group (72.50%), and the difference was statistically significant (χ2=9.476, P<0.05). The HSS score of the experimental group was higher than that of the control group (P<0.05), while the VAS and SAS scores were lower than those of the control group (P<0.05). The scores of various SF-36 scales in the experimental group were higher than those in the control group after operation (P<0.05).Conclusions: Total knee arthroplasty was considered effective in treating patients with knee osteoarthritis that meet the indications, and is beneficial to improve knee function and reduce pain in patients. The surgical treatment also reduced the level of anxiety and effectively improve the quality of life of patients. Further investigation of its clinical application on treatment of knee osteoarthritis is warranted.
