The main goal of a successful total knee arthroplasty is to relieve pain and restore function. While mechanical alignment provides excellent long-term implant survivorship, clinical and functional outcomes remain less than ideal. As a result, the focus has gradually shifted to a more personalized surgical approach based on the patient's specific characteristics. There is a pressing need for agreement on definitions of key terms to standardize limb alignment measurements and improve understanding and communication within the field. This work aims to clarify the concept of native limb alignment, outline how it is measured, and propose a standardized terminology to describe it.

Hamstring injuries are a significant concern in high-speed running and kicking sports, contributing to a high incidence and recurrence rate among athletes. Anatomical and biomechanical properties of the hamstrings, especially the biceps femoris long head, make them susceptible to strain, contributing to the high injury rate observed in athletes. Key risk factors, including prior injury history, neuromuscular deficiencies, excessive load, and muscle-tendon architecture, have been identified as contributors to injury prevalence. Eccentric strengthening exercises, particularly the Nordic hamstring exercise, are highlighted for their effectiveness in reducing the incidence of hamstring injuries. Stretching protocols, when combined with strengthening exercises, have shown potential in enhancing muscle flexibility and reducing injury risk, although their standalone effectiveness remains a subject of ongoing research.

Purpose: The objective of this study was to assess the benefits of the PENG block on pain control and functional recovery.

Methods: Randomized controlled trials in PubMed, Web of Science, Embase, and the Cochrane Library were selected, and data were meta-analyzed using a random-effects model to estimate mean difference (MD) or standardized mean differences (SMD).

Results: Eleven trials involving 1,135 patients were included. The PENG block was associated with significantly lower total opioid consumption than sham/no block (MD: -25.23, 95% CI: -27.01 to -23.45, I 2 = 0%), as well as better functional recovery. The PENG block was noninferior to the suprainguinal fascia iliaca block regarding postoperative pain scores and functional recovery and had a significant reduction in total opioid consumption (MD: -8.25, 95% CI: -16.48 to -0.02, I 2 = 68%). The PENG block was associated with similar total opioid consumption and functional recovery as the periarticular anesthetic infiltration (PAI), but worse static pain scores at 12 h (SMD: 0.41, 95% CI: 0.08-0.75, I 2 = 51%) and dynamic pain scores at 48 h after surgery (SMD: 0.36, 95% CI: 0.08-0.64, I 2 = 0%).

Conclusions: While current evidence supports the PENG block as a viable alternative to other types of peripheral analgesia in THA, existing data remain insufficient to conclude that the PENG block outperforms other peripheral analgesia when it comes to pain control or functional recovery. More well-designed randomized controlled trials are needed in the future to thoroughly explore whether the PENG block has superiority over other analgesic techniques.

Purpose: Diagnosing osteomyelitis in the foot/ankle region is challenging primarily due to anatomical constraints. While bone biopsy is the gold standard, non-invasive methods such as SPECT (single photon emission computed tomography) and MRI are sensitive but lack specificity. This study aims to evaluate SPECT/CT's potential, integrating functional and structural imaging, to improve osteomyelitis diagnosis in this region.

Methods: A systematic review following PRISMA guidelines and the Cochrane Handbook was conducted, including comprehensive research across major databases (inception to October 2022). Diagnostic studies using SPECT/CT for suspected foot/ankle bone lesions or inflammation were included. We carried out descriptive analysis, SROC curve generation, and calculated mean sensitivities and specificities. Subgroup analyses were conducted for various tracers, CT resolutions, and evaluation strategies. Sensitivity and heterogeneity analyses, bias risk, and publication bias were assessed.

Results: Eleven diagnostic studies (463 patients) were reviewed, with seven focusing on diabetic patients. Tracers included labeled leukocytes (WBC), antigranulocyte antibodies, phosphonates (BS), and gallium citrate. Clinical follow-up was the primary reference standard. Mean sensitivity of SPECT/CT for osteomyelitis diagnosis was 93.8% (95% CI: 89.7-96.4%), and specificity was 84.6% (95% CI: 65.1-94.2%). WBC SPECT/CT was more specific (79.4%) but less sensitive (89.2%) than BS SPECT/CT (specificity 46.5%, sensitivity 93.1%). Combined tracers yielded the highest mean specificity (96.4%).

Conclusion: SPECT/CT shows promising diagnostic performance for osteomyelitis in the foot/ankle region, especially when applying combined tracer methods. It is particularly advantageous in chronic, postoperative, and post-traumatic cases, offering added value compared to MRI.

Total knee arthroplasty is a highly effective intervention for end-stage osteoarthritis, yet nearly 20% of patients report dissatisfaction with clinical outcomes. This dissatisfaction is often linked to intraoperative parameters, particularly whole-leg alignment and component positioning, which might play a role in ensuring both satisfaction and long-term implant survival. Over the past two decades, alignment techniques have progressed from systematic, two-dimensional methods focused on the frontal plane to more personalized, three-dimensional approaches. This evolution has introduced inconsistencies and confusion among surgeons regarding alignment techniques, terminology, and application, underscoring the need for standardized definitions that can be universally adopted. This work provides standardized definitions for six main knee alignment techniques to enhance communication within the scientific community, particularly in clinical research. While not an exhaustive analysis of each method, this effort focuses on the foundational principles of these techniques, organized using a standardized framework to facilitate comparison and improve clarity in the field.

Purpose: Meniscal extrusion (ME) can have detrimental effects. The aim of this study was to analyze the evidence about the reliability, potential of standing and dynamic evaluations, and influencing factors identified by using ultrasound (US) to evaluate knee ME.

Methods: A systematic review of the literature was performed in February 2024 on PubMed, Scopus, and the Cochrane Library databases to select all articles, dealing with the US evaluation of ME. Relevant data of the involved articles, including study type, number of patients, age, sex, US technique, and data comparison with other radiological examinations, were extracted and collected for the study analysis.

Results: Sixty studies on 4,742 patients were included: 38 cross-sectional, ten longitudinal, two case-control, and ten biomechanical studies. A strong correlation was found between MRI and US, with good US sensitivity (96%) and specificity (82%), and moderate to excellent interrater and intrarater reliability. US examinations in the standing position with weight-bearing or more complex dynamic conditions reported a significant influence of weight-bearing on MME. US was able to identify a relationship between meniscus posterior root tear and MME, as well as between ME and both pain and early osteoarthritis.

Conclusions: US is a valuable tool for the study of ME and the identification of the association between ME and various conditions. US in dynamic and weight-bearing evaluations is useful to characterize this anatomical abnormality in different pathologies, including OA, meniscal lesions, and in the follow-up of surgical procedures, providing important data to choose the best treatment to address patients affected by ME.

Purpose: Dexmedetomidine is a widely employed adjunct in nerve block anesthesia for shoulder arthroscopy. This study aimed to assess the analgesic efficacy of dexmedetomidine as a nerve block adjuvant in patients undergoing shoulder arthroscopy.

Methods: A thorough search of PubMed/MEDLINE, Embase, Web of Science and the Cochrane Library databases was conducted to identify randomized-controlled trials comparing the effects of dexmedetomidine-enhanced shoulder arthroscopy nerve blocks against those without dexmedetomidine. This systematic review and meta-analysis followed the PRISMA guidelines. The Cochrane-recommended risk of bias tool was employed for quality and bias assessment. Statistical analysis, utilizing Review Manager 5.4 with a significance level of P < 0.05, focused on primary outcomes: duration of analgesia and postoperative 24 h morphine consumption, and secondary outcomes: motor and sensory block duration, visual analog scale pain scores and adverse events.

Results: Out of 307 articles retrieved, ten randomized-controlled trials involving 672 patients were included. Dexmedetomidine supplementation significantly prolonged the duration of analgesia (MD = 3.58, 95% CI: 2.53- 4.63, P < 0.00001, I 2 = 77%) and decreased postoperative morphine consumption (MD = -11.88, 95% CI: -17.25 to -6.52, P < 0.0001, I 2 = 41%). In addition, the dexmedetomidine group exhibited lower VAS pain scores at 1, 12 and 24 h postoperatively. No significant differences were observed in motor block duration, bradycardia (P = 0.18), hypotension (P = 0.50) and nausea and vomiting (P = 0.76). Sensitivity analyses validated the robustness of these findings.

Conclusions: This meta-analysis supports dexmedetomidine as an effective adjuvant in nerve blocks for shoulder arthroscopy. It enhances postoperative analgesia without increasing adverse events such as bradycardia, hypotension and nausea and vomiting.

Purpose: This scoping review aimed to map the literature on the effects of growth plate violation with intramedullary locking nail (IMN) at the knee in skeletally immature patients. It focused on assessing clinical and experimental outcomes, with particular attention to complications such as growth arrest and deformities.

Methods: This scoping review followed the PRISMA extension for scoping reviews, with registered protocol at the Open Science Framework. A comprehensive search of PubMed, Embase, Cochrane Library, Web of Science, and Scopus was performed for studies involving pediatric patients with open growth plates treated with IMNs at the knee and animal studies assessing physeal violations.

Results: Ten studies were included, comprising six clinical, three animal studies, and one review. The clinical studies included 89 pediatric patients treated either with retrograde femoral or antegrade tibial nailing. The youngest patient was a 7-years-old female, and there were no reported cases of growth arrest following IMN. Animal studies demonstrated that up to 7% of physeal violation did not result in significant growth disturbances, but exceeding this threshold led to growth inhibition. In addition, implant removal showed mixed results, with early bone bridge formation noted in few cases.

Conclusions: Limited physeal violations by IMN may not cause significant growth disturbances, while exceeding certain thresholds could result in adverse outcomes. The current evidence is insufficient to make recommendations on the use of IMN at the knee in skeletally immature patients, particularly to make recommendations regarding age, femur/tibia and sex. Further research is needed to establish long-term outcomes and optimal guidelines for safe physeal instrumentation.

Level of evidence: 4.

Purpose: To evaluate the effectiveness of hyperbaric oxygen therapy (HBOT) in the treatment of osteonecrosis of the femoral head (ONFH).

Methods: Search for term systems related to ONFH and HBOT in PubMed, Cochrane Library, Embase and Web of Science databases. The risk ratio (RR) was used as the effective index for dichotomous variables while mean difference (MD) and 95% confidence interval (CI) were used as the effective index for continuous variables, with a two-sided P < 0.05 considered statistically significant. I2 statistic and Q test were used to evaluate the statistical heterogeneity of the included studies.

Results: Ten studies were included, involving 568 participants. Pre-post meta-analyses to show the visual analog scale after HBOT (MD = -2.94, 95% CI: -4.27, -1.60, P < 0.0001), short form 12 physical component summary scale (SF12 PCS) (MD = 17.28, 95% CI: 8.26, 26.31, P = 0.0002), short form 12 mental component summary scale (SF12 MCS) (MD = 4.26, 95% CI: 2.56, 5.95, P < 0.00001), Harris hip score (HHS) (MD = 26.91, 95% CI: 0.35, 53.46, P = 0.05), modified Harris hip score (mHHS) (MD = 44.31, 95% CI: 13.75, 74.87, P = 0.004) were significantly different from those before treatment. The results of SF12 PCS (MD = -0.39, 95% CI: -7.85, 7.06, P = 0.92) and SF12 MCS (MD = 0.76, 95% CI: -7.02, 8.52, P = 0.85), patients' improved events (RR = 1.83, 95% CI: 0.37, 9.09, P = 0.46) showed no significant difference between the HBO and non-HBO groups.

Conclusion: The results of this study indicate that HBOT cannot be regarded as an effective measure for the treatment of early-stage necrosis of the femoral head and more large-scale randomized controlled trials are needed for further verification.
