OBJECTIVE: Fractures of the proximal humerus (PHF) are commonly treated conservatively. Evidence suggests that a period of immobilization of one week or less may lead to some advantages compared to a traditional 3-4 weeks of immobilization. The purpose of this systematic review was to assess the clinical and radiological results in the case of early rehabilitation vs. delayed rehabilitation after PHF. MATERIALS AND METHODS: In July 2023, a literature search was carried out on the PubMed, MEDLINE, and Embase databases to identify all the randomized trials comparing early rehabilitation vs. delayed rehabilitation after PHF. The following data were extracted from each included study: patients’ demographics, study design and level of evidence, follow-up times, treatment groups, evaluation scores adopted, and overall clinical and radiological findings. The quality of the trials was assessed using the Cochrane Risk of Bias Assessment. RESULTS: A total of 5 studies, including 378 patients and dealing with early vs. delayed rehabilitation in case of conservative treatment of PHF, were included in this study. Early rehabilitation was started within 1 week and consisted mainly of pendulum exercise and progressive passive mobilization. Early rehabilitation was associated with better pain and functional scores within the first 3 months in 3 studies. No difference in pain or function was reported at 6 months or longer follow-up, and no differences in complications rate were observed between early vs. delayed rehabilitation groups. CONCLUSIONS: This systematic review suggests that early mobilization within one week in case of conservative treatment of PHF leads to improved function recovery and reduced pain, especially in the first months of rehabilitation, without differences at longer follow-up and without increasing complications rate. Reducing immobilization time could accelerate function recovery and regaining independence in daily life activities. [ABSTRACT FROM AUTHOR]

Background and Objective: Myofascial pain syndrome (MPS) is a chronic musculoskeletal disorder characterized by the presence of trigger points. Among the treatment options, botulinum toxin injections have been investigated. The aim of this paper was to provide a synthesis of the evidence on intramuscular botulinum toxin injections for upper back MPS. Databases and Data Treatment: A systematic review of the literature was performed on the PubMed, Scopus and Cochrane Library, using the following formula: ("botulinum") AND ("musculoskeletal") AND ("upper back pain") OR ("myofascial pain"). Results: Ten studies involving 651 patients were included. Patients in the control groups received placebo (saline solution) injections, anaesthetic injections + dry needling or anaesthetic injections. The analysis of the trials revealed modest methodological quality: one "Good quality" study, one "Fair" and the other "Poor". No major complications or serious adverse events were reported. Results provided conflicting evidence and did not demonstrate the superiority of botulinum toxin over comparators. Most of the included trials were characterized by a small sample size, weak power analysis, different clinical scores used and non‐comparable follow‐up periods. Even if there is no conclusive evidence, the favourable safety profile and the positive results of some secondary endpoints suggest a potentially beneficial action in pain control and quality of life. Conclusion: The currently available studies show conflicting results. Their overall low methodological quality does not allow for solid evidence of superiority over other comparison treatments. Further insights are needed to properly profile patients who could benefit more from this peculiar injective approach. Significance: The randomized controlled trials included in this review compared using botulinum toxin to treat upper back MPS with placebo or active treatments (e.g., dry needling or anaesthetics) showing mixed results overall. Despite the lack of clear evidence of superiority, our study suggests that the use of botulinum toxin should not be discouraged. Its safety profile and encouraging results in pain control, motor recovery and disability reduction make it an interesting treatment, particularly in the subset of patients with moderate to severe chronic pain and active trigger points. To support the safety and efficacy of botulinum toxin, further high‐quality studies are needed. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Spinal anesthesia with local anesthetics is a viable alternative to general anesthesia in orthopedic surgery, and it is currently considered the standard of care for knee arthroscopy. The use of chloroprocaine may offer several potential advantages over other local anesthetics, including, above all, its rapid onset and short duration of action. The aim of the present retrospective study is to evaluate the post-surgical outcomes of patients who underwent knee arthroscopy using spinal anesthesia with chloroprocaine in an outpatient orthopedic setting. PATIENTS AND METHODS: Data from patients who underwent elective knee arthroscopy between January 2022 and December 2022 were collected for the present study. Spinal anesthesia with chloroprocaine 10 mg/mL was administered in the designated subarachnoid space (L3-L4 in the majority of patients). A dosage of 40 mg was used to obtain a satisfactory sensory and motor block. RESULTS: A total number of 302 patients met the inclusion criteria. No complications were reported during surgery in the present series of patients. None of the patients required bladder catheterization. In 84% of cases, the PADSS (Post-Anesthetic Discharge Scoring System) score at discharge was 10, whereas in 16% of cases, the PADSS score was 9. The mean time from anesthesia induction to first urination was 75±9.4 minutes, while the mean time from the anesthesia induction to the discharge from the hospital was 152±18.5 minutes. CONCLUSIONS: Spinal chloroprocaine for knee arthroscopy demonstrated a short motor block duration, resulting in a fast time to discharge. These limited data show that chloroprocaine may be safely and effectively applied in outpatient knee arthroscopy procedures. However, more studies, possibly with a randomized design, are required to confirm these findings. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The aging of population has dramatically broadened the total number of Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA) performed worldwide. To optimize the number of blood transfusions performed, a multimodal and multidisciplinary approach was introduced, called Patient Blood Management (PBM). The aim of the present retrospective study is to evaluate the feasibility and clinical outcomes of a PBM protocol applied in a national referral center for joint replacement surgery. PATIENTS AND METHODS: Clinical reports of 9,635 patients undergoing primary THA or TKA, from 2014 to 2019, were screened. The trends of hemoglobin value at admission and at day 4 after surgery were analyzed. Furthermore, the trend of blood bags’ requests and blood transfusions was longitudinally evaluated to assess the efficacy of our PBM protocol and its potential impact in reducing the length of stay in the hospital. RESULTS: In 2014, mean hemoglobin (Hb) levels at postoperative day 4 were 10.3 g/dl and 10.2 g/dl for TKA (unilateral and bilateral, respectively), and in 2019 were 11.3 g/dl and 11.6 g/dl (unilateral and bilateral, respectively, p=0.001). Total requested red blood cell (RBC) transfusions by each surgery over time have decreased for THA (277 in 2014 vs. 120 in 2019, p=0.001). A correlation matrix analysis between Hb level, body mass index (BMI), age, days spent in orthopedic (OR) ward and number of requested transfusions showed that RBC bags transfusions were related to the length of the hospital stay. CONCLUSIONS: A timely application of a PBM protocol in the perioperative period of TKA and THA was significantly associated to the reduction of blood transfusions and total length of hospital stay, with clear benefits for both the patients and the hospital.

OBJECTIVE: Osteoarthritis (OA) is the most common degenerative joint disease and the leading cause of disability in the adult population worldwide. The knee is the most prevalent site of symptomatic arthritis. Treatment options for OA include drugs, surgery and, more recently, biological treatments. Injectable ortho-biological treatments include autologous and more rarely heterologous preparations employed inside and outside the operating room to assist bone and soft tissue regeneration. Our aim was to analyze the rationale for use of injectable ortho-biological treatments such as platelet-rich plasma (PRP) and mesenchymal cells from bone marrow, adipose tissue, and placenta/umbilical cord, in patients with severe OA of the knee (Kellgren-Lawrence grade 4). MATERIALS AND METHODS: A search in PubMed, ScienceDirect and Google Scholar databases was performed using the following keywords: 'knee osteoarthritis' and 'biological treatment' or 'PRP' or 'adipose' or 'mesenchymal' or 'staminal' or 'stem cells'. Manual research throughout the reference lists of all retrieved articles was further conducted. RESULTS: A total of 16 articles was selected for this systematic review. The rationale for use of each ortho-biological treatment was discussed. The clinical application showed different therapeutic protocols, different follow-up periods, different outcomes analyzed and small sample size. CONCLUSIONS: Our study did not demonstrate uniform beneficial effects for the use of injectable ortho-biological. This prevents any advice for routine application in the treatment of severe knee OA (K-L IV). Further prospective clinical trials with randomization, larger sample size, and preliminary power calculation are needed to justify the use of injectable biologic agents in grade IV knee OA in everyday practice.

OBJECTIVE: The number of joint replacements is expected to dramatically increase, and the optimization of the available resources is fundamental to maintain high clinical standards while providing an efficient treatment to an increasing number of patients. The present study describes the outcomes of the application of a rapid recovery (RR) protocol in a referral center for hip and knee replacement surgery. PATIENTS AND METHODS: The medical records of every patient undergoing primary hip or knee replacement in 2019 were identified and all the relevant data were retrospectively extracted and compared to those of year 2016 (the last year before the onset of the rapid recovery protocol). The following outcomes were considered: 1) length of stay (LOS); 2) total number of TKR and THR; 3) pre- and post-operative subjective questionnaires; 4) NRS for pain at day 1 following surgery; 5) mean hemoglobin value at discharge; 6) number of blood transfusion performed; 7) complications following surgery. RESULTS: The mean LOS was significantly lower for patients managed through the rapid recovery protocol: 5.1 ± 1.4 days vs. 10.4 ± 2.3 days (p < 0.0001). The earlier discharge of patients promoted an overall increase in the total number of joint replacement procedures performed (2,806 in year 2019 vs. 2,236 in year 2016; p < 0.0001). Higher hemoglobin values at discharge were found in the RR group (10.6 ± 1.4 g/dl vs. 9.6 ± 1.2 g/dl, p = 0.049). No difference was observed in terms of clinical scores and overall complication rate. CONCLUSIONS: The application of a multimodal RR protocol for THR and TKR patients was able to reduce the length of stay and optimize the use of blood products, without increasing the risk of complications or jeopardizing the functional recovery.

OBJECTIVE: The aim of the study is to review the available literature on the use of Extracorporeal Shock Wave Therapy (ESWT) for the treatment of osteonecrosis (ON) and bone vascular disease (BVD), to understand its therapeutic potential and compare it with other therapies. MATERIALS AND METHODS: A systematic review was performed on the PubMed, Scopus, Science Direct, and Research Gate databases with the following inclusion criteria: 1) randomized controlled trials (RCTs); 2) written in English; 3) published in indexed journals within the last 25 years (1995-2020); and 4) dealing with the use of ESWT for the treatment of BVD or ON. The risk of bias was assessed by the Cochrane Risk of Bias tool for RCTs. RESULTS: Five studies involving 199 patients in total (68 female and 131 male) were included. Patients in the control groups received different treatments, like surgery, bisphosphonates in combination with prostacyclin or ESWT, and hyperbaric oxygen therapy. Looking at the quality of the available literature, none of the studies included could be considered a "good quality" study; only one was ranked as "fair" and the remaining were marked "poor" quality studies. No major complications or serious adverse events were reported in any of the included studies. Based on the available data, ESWT can produce rapid pain relief and functional improvement. CONCLUSIONS: Overall, a substandard quality of method emerged from the analysis of the literature, with most studies flawed by relevant bias. Ultimately, ESWT has the potential to be a useful conservative treatment in bone degeneration due to vascular and tissue turnover impairment. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Lateral ankle sprains are very common injuries that can be treated with different strategies. The aim of the present systematic review was to provide a comprehensive analysis on the treatment of acute lateral ankle sprains to clarify the possible differences in outcome between surgical and conservative management, different external supports, and different rehabilitation protocols. MATERIALS AND METHODS: A literature search on three different topics was carried out on PubMed, Scopus, and Web of Science databases on June 25th, 2021. The main objective of the literature search was to identify the randomized trials comparing: (1) surgery to conservative management, (2) different external supports, and (3) different rehabilitation protocols for the treatment of acute lateral ankle sprains. Two investigators extracted independently relevant data from each paper and assessed the quality of the trials using the Cochrane Risk of Bias Assessment. RESULTS: A total of 12 studies for the first topic, 8 for the second one and 4 for the last one were included in this review. 8 out of 12 RCTs demonstrated a superior outcome and better socio-economic impact of conservative treatment compared to surgical management. In the other two comparisons, due to the wide variety of braces used and the different rehabilitation protocols, inconclusive results were obtained. CONCLUSIONS: Conservative treatment should be the first choice for severe acute lateral ankle sprains, as it provides satisfactory functional outcomes without the risks and costs of surgery. It was not possible to identify the best external support, but a preference toward flexible braces emerged since they allow an earlier return to daily activities. The paucity of studies comparing different rehabilitation protocols precluded the possibility of defining the ideal one. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Conservative and surgical treatments for meniscal lesions are various and this field of orthopedic surgery is in continuous development. Stem cells represent one of the current options to stimulate meniscal healing. The present systematic review aimed at summarizing the state of art in the application of stem cells for the treatment of meniscal damage both at pre-clinical and clinical level. MATERIALS AND METHODS: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to perform this systematic review. A systematic search was performed using the PubMed (MEDLINE), EMBASE and Cochrane Library databases. All the studies dealing with the application of stem cells as a treatment for meniscal tears were pooled, data were extracted and analyzed. The studies were divided into two groups (pre-clinical and clinical), and then, discussed independently. RESULTS: A total of 18 studies were included. Thirteen were classified as "pre-clinical" and five as "clinical". The most commonly used cells were mesenchymal stem cells (MSC), derived from bone marrow (BMMSC), synovial tissue (SMSC), or adipose tissue (ADSC). Follow-ups ranged from 2 to 16 weeks for the pre-clinical studies and from 3 to 24 months for the clinical studies. All studies documented good results in terms of laboratory markers/scores, clinical and radiologic evaluation. CONCLUSIONS: Based on the currently available data, it is not possible to establish the best cell source or delivery method for the treatment of meniscal injuries. Bone Marrow derived stem cells delivered through injection represent the most studied approach, with the most promising results. However, the full impact of these therapies through their different sub-type of stem cells and implantation techniques still needs to be critically analyzed through larger randomized controlled trials with longer follow-up.

OBJECTIVE: The aim of the study was to review the available literature on the application of oxygen-ozone therapy (OOT) in the treatment of low back pain (LBP), to understand its therapeutic potential and compare it with other available treatment options. MATERIALS AND METHODS: A systematic review was performed on the PubMed and Scopus databases, with the following inclusion criteria: (1) randomized controlled trials (RCTs), (2) published in the last 20 years, (3) dealing with OOT in patients with LBP and herniated disc, (4) comparing the results of OOT with those of other treatments. The risk of bias was assessed by the Cochrane Risk of Bias tool. RESULTS: Fifteen studies involving 2597 patients in total were included. Patients in the control groups received different treatments, from oral drugs to other injections, instrumental therapy and even surgery: corticosteroids were used in 5 studies, analgesic therapy in 2 studies; placebo, microdiscectomy, laser-therapy, TENS and postural rehabilitation, percutaneous radiofrequency intradiscal thermocoagulation and psoas compartmental block were tested in the other trials. Looking at the quality of the literature, none of the studies included reached "good quality" standard, 3 were ranked as "fair" and the rest were considered "poor". Comparison of OOT results with other approaches showed that, in the majority of studies, OOT was superior to the control treatment, and also when compared to microdiscectomy, ozone showed non inferiority in terms of clinical outcomes. CONCLUSIONS: The analysis of literature revealed overall poor methodologic quality, with most studies flawed by relevant bias. However, OOT has proven to be a safe treatment with beneficial effects in pain control and functional recovery at short to medium term follow-up. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To analyze the available evidence comparing the clinical and functional outcomes of physiotherapy vs. surgical repair in the management of degenerative rotator cuff tears (RCTs), and to perform a meta-analysis to clarify the possible superiority of one approach vs. the other. MATERIALS AND METHODS: A literature search was carried out on the PubMed, Scopus and Web of Science databases on May 30th, 2020, to identify all the randomized trials comparing surgery to conservative management of degenerative rotator cuff tears. The following data were extracted from each included study: patients' demographics, study design and level of evidence, follow-up times, treatment groups, evaluation scores adopted, overall clinical findings. The quality of the trials was assessed using the Cochrane Risk of Bias Assessment. RESULTS: A total of 7 studies, including 326 patients and dealing with conservative treatment vs. surgical repair for rotator cuff tears, were included in this study. Although surgery provided superior results both in terms of VAS (p=0.017) and Constant score (p<0.0001) compared to conservative management at 1 year follow-up, this superiority did not reach the "minimal clinical important difference". Otherwise, a few data are available about long-term outcomes, thus there is insufficient evidence about the role of surgery to prevent the progression of tendon wear. CONCLUSIONS: A proper rehabilitation program is able to provide similar results compared to surgery at a short term follow-up in degenerative RCTs. Further long term data are necessary to understand if tendon repair might have a protective role towards worsening of degeneration thus providing better clinical outcome than conservative management.

OBJECTIVE: Analyzing the available evidence by comparing the role of arthroscopic surgery and conservative treatment in the management of degenerative meniscopathy. MATERIALS AND METHODS: A literature search was carried out on the PubMed, EMBASE, Scopus, and PEDro databases in May 2019 to identify all the randomized controlled trials (RCTs) comparing arthroscopic surgery to conservative management of painful but stable degenerated menisci. The quality of the RCTs was assessed using the Cochrane Risk of Bias Assessment. RESULTS: A total of 10 studies, including 1525 patients and dealing with conservative treatment vs. arthroscopic surgery were included in this review. In eight studies the effectiveness of exercise therapy was compared to surgery; in one study the effectiveness of intra-articular steroid injection was compared to surgery; in one study the effectiveness of placebo surgery was compared to partial meniscectomy. In all studies, no significant inter-group difference in terms of knee pain and knee function were observed at any follow-up evaluation. CONCLUSIONS: Degenerative meniscal tears, without symptoms of locking and catching, can be successfully managed by a proper regimen of physical therapy as a first line treatment. Surgical approach might be considered in case of poor response after conservative treatment. [ABSTRACT FROM AUTHOR]
