“…Furthermore, the analysed cohort of Voleti et al-with 100 patients compared to the 517 analysed knee joints in this study-is rather small. The results of Wernecke et al are consistent with our results for PCO, pointing out a significant larger PCO lat in male knee joints and no significant gender dependency of PCO med [28]. Bao et al examined CT scans of 80 patients to investigate posterior FCM [30].…”

“…This result is consistent with the study of Wernecke et al that analysed MRI scans of 287 male and 243 female patients in order to investigate the morphology of the posterior femoral condyles. Likewise, they found no correlation between patient age and PCO [28]. To the authors' knowledge, there are no other studies examining age-specific differences in FCM in the current literature.…”

Background: In the age of individualised arthroplasty, the question arises whether currently available standard implants adequately consider femoral condylar morphology (FCM). Therefore, physiological reference values of FCM are needed. The aim was to establish physiological reference values for anterior (ACO) and posterior condylar offset (PCO) as well as for the length of the medial (LMC) and lateral femoral condyles (LLC). Methods: The knee joints of 517 patients (mean age: 52.3 years (±16.8)) were analysed retrospectively using MRI images. Medial (med) and lateral (lat) ACO and PCO, as well as LMC and LLC, were measured. All FCM parameters were examined for association with age, gender, side and osteoarthritis. Results: Mean ACOmed was 2.8 mm (±2.5), mean ACOlat was 6.7 mm (±2.3), mean PCOmed was 25.7 mm (±4.6), mean PCOlat was 23.6 mm (±3.0), mean LMC was 63.7 mm (±5.0) and mean LLC was 64.4 mm (±5.0). Except for PCOmed, the mean values of all other FCM parameters were significantly higher in male knees compared to female knees. ACOmed and PCOmed showed significant side-specific differences. There were no significant differences in relation to age and osteoarthritis. Conclusion: The study showed significant differences in FCM side- and gender-specifically in adult knees. These aspects should be considered in the discussion of individual and gender-specific knee joint replacement.

“…However, there are scant data on the association between gender, knee cartilage defects, and knee morphology. Most anatomical studies that measured femoral PCO had small sample sizes, included no patients with knee joint osteoarthritis, or did not separately analyze the medial and lateral sides [5, 6, 10, 27, 29, 31]. The morphometric characteristics are related to genetic, environmental, and cultural conditions, as well as to lifestyle, health, and functional status.…”

“…Furthermore, accurate resection of bone and cartilage to match the thickness of the femoral component restores the posterior femoral joint line. Thus, the posterior condylar cartilage should be considered in deciding the resection depth [31]. A previous study observed that plain radiographs underestimate the size of the femoral condyles compared with MRI [27].…”

Purpose This study aimed to analyze the morphometric data from magnetic resonance images of arthritic knees in Korean adults, and to identify the existence of morphological diferences of femoral posterior condylar ofset (PCO) between genders. Methods The diferences in anthropometric PCO data in 975 patients (825 female and 150 male) were evaluated. The distances from the anterior and posterior femoral shaft cortex line to the most posterior femoral condyle tangent line were deined as the anterior-posterior dimension (AP) and the PCO. The PCO ratio (PCOR) was calculated as PCO/AP. Results The medial PCO was greater than the lateral PCO (26.3 ± 2.2 vs. 24.3 ± 2.3 mm, p < 0.01). This diference was observed in both female patients (medial: 26.2 ± 2.2 mm vs. lateral: 24.2 ± 2.2 mm, p < 0.01) and male patients (medial: 26.8 ± 2.3 mm vs. lateral: 24.8 ± 2.4 mm, p < 0.01). The medial and lateral PCO values were also greater in male patients than in female ones (p < 0.01). In contrast, PCOR was greater in female patients than in male ones, both in the medial and lateral femoral condyles (p < 0.01). Conclusions It was shown that medial and lateral PCO and PCOR were asymmetric, and that there was gender diference in Korean population in our study. In addition, our data showed that the PCOR of contemporary TKAs may be small for Asian patients that may not be suicient to meet the needs of the Korean patient population. These results conirm that a genderspeciic femoral component design is necessary to recreate the PCO for male and female Asian populations. Level of evidence Non-consecutive patients, Level III.

“…These ranges provide insights into the spread of data points within each specific aspect and offer a clear picture of the diversity and distribution of these measurements. Wernecke et al [ 23 ] used MRI to determine the associations between femoral PCC thickness and PCO in 530 healthy subjects. The authors reviewed the records of 287 male and 243 female patients who underwent MRIs for traumatic soft tissue knee injuries that did not include the femoral PCC and did not have symptomatic knee arthritis.…”

Background The maximum amount of knee flexion after total knee replacement is largely determined by the knee’s posterior condylar offset (PCO). Using magnetic resonance imaging (MRI), this study examined the relationship between PCO and the thickness of the femoral posterior condylar cartilage (PCC) in healthy people. Methodology We reviewed the medical records of 300 skeletally mature patients who did not exhibit symptoms of knee arthritis and had undergone MRI for traumatic soft tissue knee injuries that did not affect the femoral PCC. Results The study cohort consisted of 300 participants, of whom 68.3% (205) were male, and 31.7% (95) were female aged between 18 and 59 years, with a mean age of 31.13 ± 8.83 years. Most participants were under 30 years of age (45.7%), and the mean body mass index was 27.52 ± 5.64 kg/m 2 . The total medial distance was 28.50 ± 3.11 mm, ranging from 21.20 to 39.80 mm. The medial PCC was 1.71 ± 0.63 mm, ranging from 0.60 to 4.00 mm. The medial bony PCO was 38.40 mm, ranging from 18.80 to 38.40 mm. The total lateral distance was 25.24 ± 3.16 mm, ranging from 13.50 to 34.90 mm. The lateral PCC was 1.48 ± 0.75 mm, ranging from 0.30 to 10.70 mm. Finally, the lateral bony PCO was 23.76 ± 3.19 mm, ranging from 11.99 to 32.8 mm. There was a statistically significant weak positive relationship between the bony lateral PCO and the patients’ age in females only (p = 0.016; r = 0.00-0.39). There was a statistically significant mean difference in the total medial distance, medial PCC, and lateral PCC between the two knees (p < 0.05). Conclusions These findings shed light on the factors influencing these parameters, offer insightful information about the associations between particular patient characteristics and knee measurements, and may help guide clinical evaluations and treatment decisions.
