The loss of knee range of motion (ROM) is not an uncommon complication after anterior cruciate ligament reconstruction (ACLR). However, the risk factors of loss of knee ROM remain debatable. The purpose of this study was to evaluate the incidence and risk factors of loss of knee ROM at 12 months after primary ACLR performed after regaining full knee ROM preoperatively. Consecutive patients who underwent primary ACLR after regaining full ROM between January 2014 and January 2020 were retrospectively reviewed. Patients who received a surgical arthrolysis within 12 months after ACLR or those who had a loss of knee ROM at 12 months postoperatively were defined as the loss of ROM group. Possible risk factors of loss of knee ROM, including patient demographic, preoperative, surgical, and postoperative factors, were assessed. The notch wide index and radiographic parameters of the tibial spines; medial tibial spine height/tibial length (TL), lateral tibial spine height (LTSH)/TL, and tibial spine width (TSW)/TL, were also assessed. A total of 141 patients (141 knees) were included (mean age, 25.8 ± 11.4 years; male/female, 56/85). Of the 141 patients, three received surgical arthrolysis within 12 months, and 23 had a loss of knee ROM at 12 months after ACLR. On comparing patients with and without loss of knee ROM, significant differences were found in the age (p = 0.04), LTSH/TL (p = 0.02), and TSW/TL (p = 0.02). A multivariate regression analysis showed that the age (odds ratio [OR]; 1.05, 95% confidence interval [CI]: 1.01-1.09, p = 0.02), LTSH/TL (OR: 1.44, 95% CI: 1.01-2.1, p = 0.04), and TSW/TL (OR: 0.79, 95% CI: 0.65-0.97, p = 0.02) were identified as significant independent risk predictors of loss of knee ROM. This study showed that the incidence of loss of knee ROM at 12 months after primary ACLR was 18.4% (26/141). An older age, a higher LTSH/TL, and a smaller TSW/TL may be associated with loss of knee ROM at 12 months after ACLR.

Purpose: To evaluate the preoperative deterioration of an isolated meniscal tear in patients aged 40 years or older, and whether time from injury to surgery is associated with worsening of a meniscal tear. Methods: Patients aged 40 years or older who underwent arthroscopic surgery for isolated meniscal tear between 2014 and 2019 were retrospectively reviewed. The diagnostic magnetic resonance imaging (MRI) findings and arthroscopic findings were compared to evaluate the deterioration of meniscal tears. Predictors of the development of meniscal tears; patient demographic factors, duration from injury to surgery (injury to MRI and MRI to surgery), and image findings were assessed. Results: A total of 58 patients (58 knees) were included (mean age, 55.9 ± 8.5 years; male/female, 31/27). An isolated meniscal tear deteriorated in 28 (48.3%). Compared patients with and without deteriorated meniscal tear, significant differences were found in the MRI grade of meniscal tear (p = 0.03), duration from injury to MRI (164.2 ± 167.9 vs 45.2 ± 48.7 days, p < 0.001), and from MRI to surgery (148.8 ± 91.1 vs 67.6 ± 56.7 days, p < 0.001). A multivariate regression analysis showed that the duration from injury to MRI (odds ratio [OR], 1.03; p < 0.001) and from MRI to surgery (OR, 1.02; p < 0.001) were independent predictors. Conclusion: Approximately 50% of isolated meniscal tears deteriorated preoperatively in patients aged 40 years or older. The duration from injury to surgery was an independent predictor of worsening of an isolated meniscal tear.

The Beighton score (BS) is widely used to evaluate generalized joint laxity. However, the association between the BS and lateral ankle laxity is unclear. This study compared the ultrasono-graphic (US) findings of the anterior talofibular ligament (ATFL) between high-(≥6) and low-(≤3) BS groups of healthy young women. The ATFL lengths of healthy young women were measured in the stress and nonstress positions using the previously reported technique from March 2021 to January 2022. The ATFL ratio (ratio of stress to nonstress ATFL length) was used as an indicator of lateral ankle laxity. The anterior drawer test (ADT) was performed. The correlation between the BS and US findings was also examined. A total of 20 (high-BS group) and 61 (low-BS group) subjects with a mean age of 23.8 ± 1.0 years were included. The high-BS group showed a higher grade of ADT than the low-BS group. No significant differences were found in the nonstress and stress ATFL lengths and ATFL ratio (1.10 ± 0.05 vs. 1.09 ± 0.05, p = 0.19) between the groups. No correlation was found between the BS and US findings. In conclusion, this study did not detect significant differences in the US findings of the ATFL between the high-and low-BS groups.

Background: Lateral ankle sprain (LAS) is one of the most common musculoskeletal injuries. Numerous studies regarding LAS have been performed. However, there are few studies evaluating the current clinical practice of orthopaedic surgeons regarding LAS. The purpose of this study was to evaluate the current clinical practice of general orthopaedic surgeons in the treatment of LAS. Methods: A questionnaire survey was conducted from September 2020 to December 2020 in Miyazaki, Japan, to evaluate the clinical practice of general orthopaedic surgeons in the treatment of LAS. The survey was composed of 12 questions that were developed with consideration of the recommendations in the current clinical practice guidelines (CPGs) published by the Dutch orthopaedic society. The questions in this study were focused on the diagnosis, conservative treatment, rehabilitation, and the criteria for return to sports (RTS). Results: The survey response rate was 82.7% (129/156). Among the respondents, 95.3% did not consider the Ottawa Ankle Rules in the decision to perform plain radiography for patients. Rehabilitation following LAS was performed in 58.9% of patients. Eighty-five (65.9%) of the surgeons used only one factor as the criterion for RTS. The absence of pain was the most frequently used criterion (45.7%). No objective criteria were used for the RTS decision in athletes with LAS. Conclusions: The present study suggested that most general orthopaedic surgeons do not provide the care for patients with LAS recommended by the current CPGs. No objective criteria for the RTS decision are used for athletes with LAS.

Atopic dermatitis (AD), sometimes referred to as eczema, is a common skin disease, and skin barrier dysfunction and immunological disorders are well recognized. However, surgical wound complications after orthopaedic surgery in patients with AD have not been described. This study aimed to report four patients with AD who developed foreign body reactions to FiberWire sutures with or without surgical wound infection (SSI) after knee cruciate ligament reconstruction (CLR). The mean age was 19.8 (range, 16-25) years, and patients 1 and 3 underwent reconstructions of the posterior and anterior cruciate ligament, respectively. At a mean of 7.5 (range, 4-10) weeks postoperatively, discharge from the surgical wound at the tibial side of the fixed graft was identified. All patients were treated with continuous saline lavage and antibiotics; however, their wounds did not heal. Second-look arthroscopy and hardware removal were performed at a mean 12.2 (range, 9-15) months postoperatively. Proliferated granulation tissue surrounding the FiberWire was identified. Intraoperative wound cultures were negative in three of the four patients. Histological examination of the tissues adjacent to the FiberWire revealed a foreign body reaction. All wounds healed immediately after the second surgery. In addition to SSI, foreign body reactions are more likely to occur in patients with AD than in those without AD. Preoperative management of AD by dermatologists and consideration of appropriate suture materials are mandatory to reduce surgical wound complications after knee CLR in patients with AD.

Objectives Medical examinations for adult elite athletes are performed all over the world, however, no studies in the relevant English literature have reported on orthopaedic medical examinations for young amateur athletes. The purpose of this study was to report the results of orthopaedic medical examinations of the spine and lower extremities in young amateur athletes. Methods This repeated cross-sectional study from 2014 to 2018 included a total of 323 young amateur athletes (age, 12-18 years) who were active in one of the following four sports: boxing, canoeing, weightlifting and track and field. The orthopaedic medical examination consisted of six assessments (physical examinations, the generalised joint laxity, muscle and joint tightness, static alignment and muscle volume of the lower extremities and the medial longitudinal arch of the foot). Questions regarding pain in the spine and lower extremities were also performed. Results Among 323 young amateur athletes, 17 (5.3%) had received orthopaedic treatment at the time of the medical examination, with spondylolysis being the most common cause (29.4%, 5/17). Among 306 young athletes who had not received orthopaedic treatment, 61 (19.9%) had at least one positive finding in physical examinations or had pain in the spine or lower extremities. Anterior drawer test of the ankle and Kemp test for the spine accounted for 34% and 28% of positive findings, respectively. Low back pain and knee pain accounted for 58% and 16% of pain, respectively. Conclusions The present study showed that approximately one-fifth of young amateur athletes who had not received orthopaedic treatment had pain in the spine and lower extremities and positive findings in physical examinations that may require orthopaedic treatments. In addition to the early detection of injuries, orthopaedic medical examinations for young amateur athletes provide an opportunity to educate such athletes.
