Abstract
BACKGROUND Radiocarpal dislocations are rare but potentially devastating injuries. Poorer outcomes are associated with inadequate or lost reduction, such as ulnar translocation, but no consensus exists on the ideal fixation technique. Dorsal bridge plate fixation has been described for various settings in the treatment of complex distal radius fractures and can be fixed distally to the second or third metacarpal, but its application for radiocarpal dislocations has not been established.
AIM To determine whether distal fixation to the second or third metacarpal matters.
METHODS Using a cadaveric radiocarpal dislocation model, the effect of distal fixation was studied in two stages: (1) A pilot study that investigated the effect of distal fixation alone; and (2) a more refined study that investigated the effect of described techniques for distal and proximal fixation. Radiographs were measured in various parameters to determine the quality of the reduction achieved.
RESULTS The pilot study found that focusing on distal fixation alone without changing proximal fixation results in ulnar translocation and volar subluxation when fixing distally to the second metacarpal compared with the third. The second iteration demonstrated that anatomic alignment in coronal and sagittal planes could be achieved with each technique.
CONCLUSION In a cadaveric radiocarpal dislocation model, anatomic alignment can be maintained with bridge plate fixation to the second metacarpal or the third metacarpal if the described technique is followed. When considering dorsal bridge plate fixation for radiocarpal dislocations, the surgeon is encouraged to understand the nuances of different fixation techniques and how implant design features may influence proximal placement.

Abstract
Total elbow arthroplasty (TEA) is increasingly used, especially in patients with rheumatoid arthritis (RA) and distal humerus fractures (DHFs). This narrative review of the recent literature published in 2022 reached the following conclusions: 1) Age greater than 80 is not a contraindication for TEA. 2) The estimated 10-year survival reported for linked TEAs is 92%, and unlinked TEAs 84%. 3) For DHFs in the elderly, regarding the flexion/extension arc, TEA gives substantially better results than open reduction and internal fixation (ORIF). The reoperation and elbow stiffness rates are substantially lower in TEA than in ORIF. 4) Comparing distal humeral hemiarthroplasty (DHH) vs. TEA in individuals over 65 years with a non-reconstructable DHF favors DHH regarding the range of motion but with a similarly high rate of adverse events in the two surgical techniques. 5) The rate of eradication of periprosthetic joint infection (PJI) is 69-76% with two-stage, 71% with resection arthroplasty, 67% with one-stage, 58% with DAIR, and 40% with elbow arthrodesis.

Abstract
Painful end-stage wrist osteoarthritis (OA) unresponsive to conservative treatment is frequently managed with total wrist arthrodesis (TWA), which might render pain alleviation and ameliorate function, pain, and grip strength. Usual indications for TWA include inflammatory arthritis, idiopathic degenerative OA and posttraumatic OA, Kienböck's illness, brachial plexus palsy, cerebral paralysis, infraclavicular brachial plexus blocks and other spastic and contracture base illnesses, scapholunate advanced collapse, scaphoid nonunion advanced collapse, and failure of other surgical techniques such as after failed total wrist arthroplasty, four-corner fusion, proximal row carpectomy and severe ligament injuries (this procedure is carried out when all other treatment alternatives have failed to control the individual's symptoms). TWA is commonly carried out with a dorsal plate fixed from the distal radius to the third metacarpal. However, other surgical procedures have been reported, including intramedullary fixation and new implants that do not cross the third carpometacarpal joint or some procedures without utilizing hardware for example using a vascularized fibular grafting In individuals with rheumatoid arthritis. TWA has been shown to give persistent and painless stability for 20 years or more. The rate of adverse events for TWA ranges from 0.1% to 6.1%, though some authors have published that it can be as high as 27%. The most common adverse events are tendon ruptures, peri-implant fractures of the third metacarpal, the need for hardware removal, and constant pain at the third carpometacarpal joint. In idiopathic degenerative OA, the reoperation rate following TWA has been reported as high as 63%. While TWA can render foreseeable pain alleviation and ameliorate function, orthopedic surgeons should remember that this surgical technique is not without its risks and that the accessibility of many surgical procedures requires orthopedic surgeons to scrupulously contemplate the risks and benefits of each alternative for the individual in front of them.

Abstract
Contemporary treatments for osteoarthritis (OA) pursue only to alleviate the pain caused by the illness. Discovering disease-modifying osteoarthritis drugs (DMOADs) that can induce the repair and regeneration of articular tissues would be of substantial usefulness. The purpose of this manuscript is to review the contemporary role of DMOADs in managing OA. A narrative literature review on the subject, exploring the Cochrane Library and PubMed (MEDLINE) was performed. It was encountered that many publications have analyzed the impact of several DMOAD methods, including anti-cytokine therapy (tanezumab, AMG 108, adalimumab, etanercept, anakinra), enzyme inhibitors (M6495, doxycycline, cindunistat, PG-116800), growth factors (bone morphogenetic protein-7, sprifermin), gene therapy (micro ribonucleic acids, antisense oligonucleotides), peptides (calcitonin) and others (SM04690, senolitic, transient receptor potential vanilloid 4, neural EGFL-like 1, TPCA-1, tofacitinib, lorecivivint and quercitrin). Tanezumab has been demonstrated to alleviate hip and knee pain in individuals with OA but can cause major adverse events (osteonecrosis of the knee, rapid illness progression, augmented prevalence of total joint arthroplasty of involved joints, particularly when tanezumab is combined with nonsteroidal anti-inflammatory drugs. SM04690 (a Wnt inhibitor) has been demonstrated to be safe and efficacious in alleviating pain and ameliorating function as measured by the Western Ontario and McMaster Universities Arthritis Index. The intraarticular injection of lorecivivint is deemed safe and well tolerated, with no important reported systemic complications. In conclusion, even though DMOADs seem promising, their clinical effectiveness has not yet been demonstrated for managing OA. Until forthcoming studies can proved the medications' capacity to repair and regenerate tissues affected by OA, physicians should keep using treatments that only intend to alleviate pain.

Abstract
A radiosynovectomy (RS) should be indicated when recurrent articular bleeds related to chronic hemophilia synovitis (CHS) exist, established by clinical examination, and confirmed by imaging techniques that cannot be constrained with hematological prophylaxis. RS can be performed at any point in life, mainly in adolescents (>13−14 years) and adults. Intraarticular injection (IAI) of a radioactive material in children might be arduous since we need child collaboration which might include general anesthesia. RS is our initial option for management of CHS. For the knee joint we prescribe Yttrium-90, while for the elbow and ankle we prescribe Rhenium-186 (1 to 3 IAIs every 6 months). The procedure is greatly cost efficient when compared to surgical synovectomy. Chemical synovectomy with rifampicin has been reported to be efficacious, inexpensive, simple, and especially practical in developing countries where radioactive materials are not easily available. Rifampicin seems to be more efficacious when it is utilized in small joints (elbows and ankles), than when utilized in bigger ones (knees). When RS and/or chemical synovectomy fail, arthroscopic synovectomy (or open synovectomy in some cases) should be indicated. For us, surgery must be performed after the failure of 3 RSs with 6-month interims. RS is an effective and minimally invasive intervention for treatment of repeated articular bleeds due to CHS. Although it has been published that the risk of cancer does not increase, and that the amount of radioactive material used in RS is insignificant, the issue of chromosomal and/or deoxyribonucleic acid (DNA) changes remains a concern and continued surveillance is critical. As child and adulthood prophylaxis becomes more global, RS might become obsolete in the long-term.

Abstract
Half of the individuals who experience an anterior cruciate ligament reconstruction (ACLR) suffer from knee osteoarthritis (OA) 12-14 years later. Elements that make a contribution to the appearance of OA following ACLR are anomalous anterior tibial displacement and anomalous tibial rotation in the course of the stance phase of walking (exhibited in 85% of operated knees). Individuals who undergo an early ACLR (5 days on average following anterior cruciate ligament [ACL] breakage) have an inferior frequency of radiographically apparent tibiofemoral OA at 32-37 years of follow-up than individuals with ACL rupture who did not experience the procedure. Nevertheless, the percentage of symptomatic OA, radiographically apparent patellofemoral OA and knee symptoms are alike in both groups. At 15 years of follow-up, 23% of knees that experienced an anatomic ACLR suffer from OA, while this percentage augments to 44% if the ACLR was non-anatomic. Knees of individuals who experience ACLR need total knee arthroplasty at an earlier age than healthy knees. Intra-articular injections of interleukin-1 receptor antagonist and corticosteroids may reduce the risk of OA after ACLR.

Abstract
Parkinson’s disease (PD) is a common neurodegenerative disorder. When patients with PD undergo total knee arthroplasty (TKA) for knee osteoarthritis, poorer knee function and poorer quality of life are obtained than in matched cohorts (MCs). However, the degree of patient satisfaction is usually high. The mean length of stay is 6.5% longer in patients with PD than in MCs. Compared with MCs, patients with PD undergoing TKA have a 44% higher risk of complications. In patients with PD, the overall complication rate is 26.3% compared with 10.5% in MCs; the periprosthetic joint infection rate is 6.5% in patients with PD vs 1.7% in MCs; and the periprosthetic fracture rate is 2.1% in patients with PD vs 1.7% in MCs. The 90-day readmission rate is 16.29% in patients with PD vs 12.66% in MCs. More flexion contractures occur in patients with PD. The rate of medical complications is 4.21% in patients with PD vs 1.24% in MCs, and the rate of implant-related complications is 5.09% in patients with PD vs 3.15% in MCs. At 5.3 years’ mean follow-up, the need for revision surgery is 23.6%. The 10-year implant survival, taking revision of any of the components as an endpoint, is 89.7% in patients with PD vs 98.3% in MCs.

Abstract
Total knee arthroplasty (TKA) is a commonly used option in advanced stages of knee arthropathy in people with hemophilia (PWH). The objective of this article is to determine what the complication rates and implant survival rates in PWH are in the literature. A literature search was carried out in PubMed (MEDLINE), Cochrane Library, Web of Science, Embase and Google Scholar utilizing the keywords "hemophilia TKA complications" on 20 October 2022. It was found that the rate of complications after TKA in PWH is high (range 7% to 30%), although it has improved during the last two decades, possibly due to better perioperative hematologic treatment. However, prosthetic survival at 10 years has not changed substantially, being in the last 30 years approximately 80% to 90% taking as endpoint the revision for any reason. Survival at 20 years taking as endpoint the revision for any reason is 60%. It is possible that with a precise perioperative control of hemostasis in PWH, the percentage of complications after TKA can be diminished.

Abstract
Periprosthetic joint infection (PJI) is a major adverse event of primary total knee arthroplasty (TKA) from the patient's perspective, and it is also costly for health care systems. In 2010, the reported incidence of PJI in the first 2 years after TKA was 1.55%, with an incidence of 0.46% between the second and tenth year. In 2022, it has been published that 1.41% of individuals require revision TKA for PJI. The following risk factors have been related to an increased risk of PJI: male sex, younger age, type II diabetes, obesity class II, hypertension, hypoalbuminemia, preoperative nutritional status as indicated by prognostic nutritional index (PNI) and body mass index, rheumatoid arthritis, post-traumatic osteoarthritis, intra-articular injections prior to TKA, previous multi-ligament knee surgery, previous steroid therapy, current tobacco use, procedure type (bilateral), length of stay over 35 days, patellar resurfacing, prolonged operative time, use of blood transfusions, higher glucose variability in the postoperative phase, and discharge to convalescent care. Other reported independent risk factors for PJI (in diminishing order of importance) are congestive heart failure, chronic pulmonary illness, preoperative anemia, depression, renal illness, pulmonary circulation disorders, psychoses, metastatic tumor, peripheral vascular illness, and valvular illness. Preoperative intravenous tranexamic acid has been reported to diminish the risk of delayed PJI. Knowing the risk factors for PJI after TKA, especially those that are avoidable or controllable, is critical to minimizing (ideally preventing) this complication. These risk factors are outlined in this article.

Abstract
BACKGROUND This narrative review of the literature aims to analyze the utilization of stromal vascular fraction (SVF) and decellularized extracellular matrices (dECMs) in various pathologies related to orthopedic surgery. METHODS A literature search was carried out in PubMed on February 15, 2022, using "Stroma Vascular Fraction and Orthopedic Surgery" and "Decellularized Extracellular Matrices and Orthopedic Surgery" as keywords. A total of 278 articles were found, of which 28 papers were selected because they seemed to be the most appropriate concerning the title of the article. RESULTS The reported results have shown that intra-articular injection of SVF seems to be a safe and efficacious method for managing knee osteoarthritis (OA). Platelet-rich plasma (PRP) and SVF are safe and effective management for intractable Achilles tendinopathy in humans, although subjects treated with SVF recover earlier. There are promising results in utilizing adipose-derived mesenchymal stromal cells in chronic lateral epicondylitis of the elbow in athletes. Ready-to-use ECM/SVF gel seems to be a good therapeutic option promoting the regeneration of the articular cartilage in subjects with injuries of the cartilage. The SVF can safely be used to treat diabetic subjects suffering from chronic foot ulcers. CONCLUSION There are scarce high-quality data for utilizing cell-based approach in soft tissue injuries of the knee in athletes. Experimental studies indicate that SVF could be a new option to osseous regeneration. Other experimental studies support the utilization of dECMs as a scaffold for the regeneration of large osseous defects, cell-derived dECMs scaffolds to repair articular cartilage injuries, and utilization of xenogeneic acellular muscles to manage volumetric muscle loss where there is a lack of donor site.Intra-articular injections of SVF seems to be a safe and efficacious method for managing OA of the knee joint. Platelet-rich plasma (PRP) and SVF are safe and efficacious methods for the management of intractable Achilles tendinopathy in humans, although subjects treated with SVF recover earlier.

Abstract
The appearance of bone metastases (BM) in individuals with advanced solid cancers (breast, prostate, lung) often worsens their quality of life and prognosis. Although none have been fully effective, several strategies have been used to combat BM. Hence, the need for new data that could be useful for treating bone metastasis. To this end, we reviewed the recent literature on the subject. About patients with prostate cancer, treatments with PIP5K1α inhibitors have been found to inhibit tumor invasion and metastasis, and G protein-coupled receptor class C group 5 member A (GPRC5A) could be a future therapeutic target. Regarding patients with breast cancer, we found the following: Asperolide A could be another curative drug; targeting transforming growth factor-beta (TGFβ) and bone morphogenetic protein (BMP) signaling pathways, along with osteoclast activity, could be a favorable therapeutic approach in the preclusion of osteolytic bone destruction; TRAF6 inhibitors such as 6877002 appear promising; aiming the BMP4-SMAD7 signaling axis is an innovative therapeutic approach; there is favorable proof for the plausible therapeutic utilization of bone aiming immunostimulatory MOF (BT-isMOF) nanoparticles, and inhibition of IL4R and macrophages could have therapeutic benefits. For lung cancer, the function of LIGHT in osteolytic osseous illness instigated by metastatic non-small cell lung cancer should be highlighted.

Abstract
Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) is a serious adverse event. Culturing of samples of periprosthetic tissue is the standard technique utilized for the microbiological diagnosis of PJI. However, this technique is neither sensitive nor specific since in PJI the microorganisms are usually in a biofilm on the surface of the prosthesis. The objective of this paper is to know the role of sonication in the diagnosis of PJI after TKA. Sonication consists in taking samples of bacteria from biofilms adhered to the prosthetic surface. The reported sensitivity for the diagnosis of PJI of the periprosthetic tissue cultures and sonicate fluid cultures is 54% and 75%, apiece. The specificity is 98% and 87%, respectively. In conclusion, the sonication technique is a dependable test for the diagnosis of PJI after TKA with a greater sensitivity and specificity than the conventional periprosthetic tissue cultures. Sonication of polyethylene liners, rather than the whole prosthesis, has been reported to be sufficient for diagnosis of prosthetic joint infection.

Abstract
Open reduction and internal fixation is the gold standard treatment for tibial plateau fractures. However, the procedure is not free of complications such as knee stiffness, acute infection, chronic infection (osteomyelitis), malunion, non-union, and post-traumatic osteoarthritis. The treatment options for knee stiffness are mobilisation under anaesthesia (MUA) when the duration is less than 3 months, arthroscopic release when the duration is between 3 and 6 months, and open release for refractory cases or cases lasting more than 6 months. Early arthroscopic release can be associated with MUA. Regarding treatment of acute infection, if the fracture has healed, the hardware can be removed, and lavage and debridement can be performed along with antibiotic therapy. If the fracture has not healed, the hardware is retained, and lavage, debridement, and antibiotic therapy are performed (sometimes more than once until the fracture heals). Fracture stability is important not only for healing but also for resolving the infection. In cases of osteomyelitis, treatment should be performed in stages: aggressive debridement of devitalised tissue and bone, antibiotic spacing and temporary external fixation until the infection is resolved (first stage), followed by definitive surgery with grafting or soft tissue coverage depending on the bone defect (second stage). Intra-articular or extra-articular osteotomy is a good option to correct malunion in young, active patients without significant joint damage. When malunion is associated with extensive joint involvement or the initial cartilage damage has resulted in knee osteoarthritis, the surgical option is total knee arthroplasty.

Abstract
BACKGROUND The objective of this prospective randomized pilot study is to compare, by computed tomography (CT), the mobility of syndesmosis after static fixation (SF) or dynamic fixation (DF) in ankle fractures with syndesmotic rupture (AFSR) in adults, and to compare this mobility with that of healthy ankles. METHODS Forty-two patients with an AFSR were randomized to 2 groups: SF (N=21) or DF (N=21). Seven patients were lost to follow-up. Ultimately, 35 patients (SF, N=20; DF, N=15) were analyzed. The clinical results were assessed with the American Orthopedic Foot and Ankle Society scale. To assess syndesmosis mobility, CT in 30° of plantar flexion (PFlex) and 20° of dorsal flexion (DFlex) was performed on both ankles one year after the fracture. Four parameters were measured: anterior tibiofibular distance, posterior tibiofibular posterior distance, angle of fibular rotation (AFR), and anteroposterior fibular translation. RESULTS The AFR between DFlex and PFlex was more similar to the non-affected side in the DF group. The other three parameters showed no statistical differences between types of fixation. The mean loss of AFR compared with the non-affected side was 1.2° in the SF group and 0.1° in the DF group. No clinical differences between the SF group and the DF group were found. No correlation between clinical and radiological results was observed. CONCLUSION The AFR was more similar to the non-affected side in the DF group. However, this finding did not correlate with a better clinical result.

Abstract
This article examines the elements that affect the return to sport (RTS) and the risk and percentages of reinjury following a prior primary anterior cruciate ligament reconstruction (ACLR). The prevalence of RTS following ACLR ranges from 71% to 83%. Concerning elements affecting RTS, a limb symmetry index score of 90 or more duplicates the likelihood of RTS and triplicates it when the International Knee Documentation Committee (IKDC) score is 95 or more, irrespective of age. Other elements recognized to be preindicative of RTS at 1 year include complete rehabilitation, age ≤25, and higher IKDC scores. The prevalence of reinjury following ACLR ranges from 1.5% to 37.5% (between 9% and 29% in the majority of reports). It has been published that 1 in 5 individuals suffers reinjury to either knee, and that male individuals are more prone to reinjure following ACLR. The highest percentage of ACLR reinjury happens in younger male (<18 years), being substantially higher than in female of the same age. Passing a combination of functional tests with predetermined cut-off points utilized as RTS criteria are related diminished ACLR reinjury percentages.

Abstract
Orthobiologics are organic and synthetic materials that help in the cure of musculo-skeletal problems and are utilized in Orthopaedic Surgery, both in and out of the surgical theater, to augment the possibilities of curing bone and soft tissue lesions. Taking into account that their effect is frequently multifactorial and, in some occasions not entirely comprehended, together with the insufficient clinical information, orthobiologics should be scrupulously assessed against other secure and clinically accepted options. The fundamental orthobiologics today ready for use in Orthopedic Surgery are the following: osseous hollow fillers, extracellular matrix (ECM) substances, platelet-rich plasma (PRP), bone morphogenetic protein-2 (BMP-2), bone marrow aspirate (BMA), bone marrow aspirate concentrate (BMAC), and mesenchymal stem cells (MSCs). It is predictable that in the time to come we will have more secure and more efficacious orthobiologics. Meanwhile, it is paramount that orthopedic surgeons have appropriate information of contemporary orthobiologics (biological adjuvants) so that they can utilize them correctly.

Abstract
The current applications of the virtual elements of artificial intelligence (AI), machine learning (ML), and deep learning (DL) in total knee arthroplasty (TKA) are diverse. ML can predict the length of stay (LOS) and costs before primary TKA, the risk of transfusion after primary TKA, postoperative dissatisfaction after TKA, the size of TKA components, and poorest outcomes. The prediction of distinct results with ML models applying specific data is already possible; nevertheless, the prediction of more complex results is still imprecise. Remote patient monitoring systems offer the ability to more completely assess the individuals experiencing TKA in terms of mobility and rehabilitation compliance. DL can accurately identify the presence of TKA, distinguish between specific arthroplasty designs, and identify and classify knee osteoarthritis as accurately as an orthopedic surgeon. DL allows for the detection of prosthetic loosening from radiographs. Regarding the architectures associated with DL, artificial neural networks (ANNs) and convolutional neural networks (CNNs), ANNs can predict LOS, inpatient charges, and discharge disposition prior to primary TKA and CNNs allow for differentiation between different implant types with near-perfect accuracy.

Abstract
BACKGROUND This study compares the outcomes of patients undergoing total ankle arthroplasty (TAA) and tibiotalar fusion (ankle arthrodesis) in patients with end-stage osteoarthritis. The primary outcome assessed was Patient Reported Outcome Measures (PROMS); secondary outcomes included the incidence of revision, re-operation, and complications. METHODS A systematic review of studies examining the outcomes of patients undergoing TAA and/or tibiotalar fusion from 2006 to 2020 was conducted. Individual cohort studies and randomized control trials were included. Outcomes were assessed at two and five years. RESULTS 21 studies were included: 16 arthroplasty (2,016 patients) and 5 arthrodesis (256 patients) studies. No significant difference in PROMS was evident two years post-surgery - American Orthopaedic Foot and Ankle Society (AOFAS) scores were 78.8 (95% CI-confidence interval: 76.6-80.8; n=1548) and 80.8 (95% CI: 80.1-81.5; n=206 patients) for the arthroplasty and arthrodesis groups respectively. Two years post-surgery the revision rates for the arthroplasty and arthrodesis groups were similar - 3.5% (n=9) and 3.7% (n=61) respectively (OR-odds ratio: 1.05; 95% CI: 0.51-2.13); however, the re-operation rate was 2.5 times higher for the arthroplasty group (12.2%) in comparison to the arthrodesis group (5.1%) (OR: 2.57; 95% CI: 1.43-4.62). Documented complications in the arthroplasty group were half those documented in the arthrodesis group two years post-surgery (OR: 0.53; 95% CI: 0.37-0.77). No arthrodesis studies were found which contained mean 5-year follow-up data within the study period. CONCLUSION Despite recent developments in TAA design, we found no clear evidence as to their superiority over ankle arthrodesis when considering patient outcomes two years postoperatively. However, this conclusion could be debatable in some types of patients such as diabetic patients, posttraumatic patients and patients with stiff hindfoot and midfoot.

Abstract
The effect of biomechanical footwear on pain from knee osteoarthritis (OA) is still unclear and controversial. The purpose of this article is to review the literature with the aim of answering the following question: What is the impact of biomechanical footwear on pain from knee OA? A Cochrane Library and PubMed (MEDLINE) search related to the effect of biomechanical footwear on pain from knee OA was performed. Several authors have reported knee pain alleviation in people with knee OA using biomechanical footwear. However, many of them have also stated that further investigation was required to evaluate its long-run effectiveness and safety, as well as replication, prior to reaching conclusions about the clinical value of this treatment. The cost of biomechanical footwear treatment is around 5,000 US dollars. Considering the weak evidence currently available on the efficacy of biomechanical footwear and its high cost, we do not advise the routine use of that treatment until it can be unequivocally confirmed that it is truly effective for pain alleviation in patients with knee OA.

Abstract
The main indications for osteochondral allografts (OCA) transplantation of the knee are the following: Symptomatic full-thickness cartilage lesions greater than 3 cm2; deep lesions with subchondral damage; and revision techniques when a previous surgical procedure has failed. Dowel and shell techniques are the two most commonly used for OCA transplantation. The dowel technique is appropriate in most cartilage lesions; however, geometrically irregular lesions may need the shell technique. Factors related to better outcomes after OCA transplantation are the following: unipolar lesions; patients younger than 30 years; traumatic lesions; and when the treatment is carried out within 12 months from the onset of symptoms. A systematic review found a survivorship rate of 89% at 5 years. Other systematic review showed a mean failure rate of 25% at 12 years with a reoperation rate of 36%. Seventy-two per cent of the failures were conversion to total knee arthroplasty (TKA) (68%) or unicompartmental knee arthroplasty (UKA) (4%). Twenty-eight per cent of failures were graft removal, graft fixation, and graft revision. In this systematic review, patellofemoral lesions (83%) had a higher reoperation rate than lesions affecting the tibial plateau or the femoral condyles. Overall, OCA transplantation showed a successful result in 75% of patients at 12 years follow-up.

Abstract
There are several manners to take care of the hemophilic ankle in the initial phases of degeneration of the articular cartilage, in the event that hematologic prophylaxis is unsuccessful in accomplishing no bleeds. Some of these are nonoperative, with which management must start. These are Physical and Rehabilitation Medicine protocols and the utilization of orthoses (patellar tendon bearing). When these are unsuccessful, more aggressive types of treatment can be utilized, such as radiosynovectomy and some surgical operations (open or arthroscopic removal of anterior osteophyte of the distal part of the tibia, arthroscopic ankle debridement). Nonetheless, in the late phases of degeneration of the articular cartilage (advanced arthropathy), the solely options are surgical: ankle fusion or total ankle arthroplasty. The review of the literature has shown that the percentage of consolidation is between 90% and 100%, and that the percentage of postoperative infection is between 0% and 10%%. When the Ilizarov external fixator is utilized for ankle fusion, the percentage of pin tract infection is around 14%. Ankle fusion is a secure surgical technique that meliorates articular pain and improves the quality of life of hemophilic patients.

Abstract
BACKGROUND In patients with severe osteoarthritis of the knee with prior ipsilateral hip fusion who require total knee arthroplasty (TKA), a controversial issue is whether to first convert the hip fusion to a total hip arthroplasty (THA) or to perform TKA without reconstruction of the hip. Also, immobility of the ipsilateral, fused hip adds significant technical challenge because the usual positioning of the leg requires modification in order to gain access needed for the TKA. TECHNIQUE In such cases, we position the patient with the knee suspended, similar to how we perform knee arthroscopy. In our experience, the ipsilateral knee has significant deformity and is best addressed with a constrained, hinged TKA. RESULTS In 3 patients with severe knee osteoarthritis with prior ipsilateral hip fusion-a 72-year-old man and a 79-year-old woman with hip arthrodesis due to posttraumatic arthritis and an 81-year-old woman with hip arthrodesis due to congenital dislocation of the hip-rotating-hinge knee prostheses were implanted due to severe knee instability. All 3 patients had satisfactory results, without complications, after follow-up of 1 to 5 years. CONCLUSIONS We obtained satisfactory results in the short and medium term without previously converting the hip arthrodesis to THA by positioning patients with the knee suspended, in a way similar to when knee arthroscopy is performed, and implanting rotating hinge TKAs due to severe preoperative knee instability.

Abstract
Distal radioulnar joint (DRUJ) instability and triangular fibrocartilage complex (TFCC) tears are more usual than estimated and are frequently overlooked. Diagnosis is often clinical, which can be confirmed using computed tomography (CT) scan and magnetic resonance imaging (MRI). In doubtful cases, bilateral computed tomography in neutral forearm rotation, supination, and pronation should also be performed. Wrist arthroscopy can be diagnostic and therapeutic for ulnar-sided wrist pain. Two systematic reviews showed equivalent outcomes between open and arthroscopic repair of the TFCC. There is scant proof to advise one technique over the other in clinical practice. TFCC repair and reconstruction are contraindicated when there is a bony deformation of the radius or ulna or osteoarthritis of the DRUJ. With the advancement of implant arthroplasty, salvage procedures are less desirable. Constrained distal radioulnar arthroplasty is stable, and the longevity is encouraging.

Abstract
The treatment of small to moderate size defects in revision total knee arthroplasty (rTKA) has yielded good results with various techniques (cement and screws, small metal augments, impaction bone grafting and modular stems). However, the treatment of severe defects remains problematic. Severe defects have typically been treated with large allograft and metaphyseal sleeves. The use of structural allograft has decreased in recent years due to increased long-term failure rates and the introduction of highly porous metal augments (cones and sleeves). A systematic review of level IV evidence studies on the outcomes of rTKA metaphyseal sleeves found a 4% rate of septic revision, and a rate of septic loosening of the sleeves of 0.35%. Aseptic re-revision was required in 3% of the cases. The rate of aseptic loosening of the sleeves was 0.7%, and the rate of intraoperative fracture was 3.1%. The mean follow-up was 3.7 years. Another systematic review of tantalum cones and sleeves found a reoperation rate of 9.7% and a 0.8% rate of aseptic loosening per sleeve. For cones, the reoperation rate was 18.7%, and the rate of aseptic loosening per cone was 1.7%. The reported survival of metal sleeves was 99.1% at three years, 98.7% at five years and 97.8% at 10 years. The reported survival free of cone revision for aseptic loosening was 100%, and survival free of any cone revision was 98%. Survival free of any revision or reoperation was 90% and 83%, respectively.

Abstract
Tarsal tunnel syndrome (TTS) is a neuropathy due to compression of the posterior tibial nerve and its branches. It is usually underdiagnosed and its aetiology is very diverse. In 20% of cases it is idiopathic. There is no test that diagnoses it with certainty. The diagnosis is usually made by correlating clinical history, imaging tests, nerve conduction studies (NCSs) and electromyography (EMG). A differential diagnosis should be made with plantar fasciitis, lumbosacral radiculopathy (especially S1 radiculopathy), rheumatologic diseases, metatarsal stress fractures and Morton’s neuroma. Conservative management usually gives good results. It includes activity modification, administration of pain relief drugs, physical and rehabilitation medicine, and corticosteroid injections into the tarsal tunnel (to reduce oedema). Abnormally slow nerve conduction through the posterior tibial nerve usually predicts failure of conservative treatment. Indications for surgical treatment are failure of conservative treatment and clear identification of the cause of the entrapment. In these circumstances, the results are usually satisfactory. Surgical success rates vary from 44% to 96%. Surgical treatment involves releasing the flexor retinaculum from its proximal attachment near the medial malleolus down to the sustentaculum tali. Ultrasound-guided tarsal tunnel release is possible. A positive Tinel’s sign before surgery is a strong predictor of surgical relief after decompression. Surgical treatment achieves the best results in young patients, those with a clear aetiology, a positive Tinel’s sign prior to surgery, a short history of symptoms, an early diagnosis and no previous ankle pathology.

Abstract
Surgical reconstruction in anterior cruciate ligament (ACL) ruptures has proven to be a highly effective technique that usually provides satisfactory results. However, despite the majority of patients recovering their function after this procedure, ACL reconstruction (ACLR) is still imperfect. To improve these results, various biological augmentation (BA) techniques have been employed mostly in animal models. They include: (1) growth factors (bone morphogenetic protein, epidermal growth factor, granulocyte colony-stimulating factor, basic fibroblast growth factor, transforming growth factor-β, hepatocyte growth factor, vascular endothelial growth factor, and platelet concentrates such as platelet-rich plasma, fibrin clot, and autologous conditioned serum), (2) mesenchymal stem cells, (3) autologous tissue, (4) various pharmaceuticals (matrix metalloproteinase-inhibitor alpha-2-macroglobulin bisphosphonates), (5) biophysical/environmental methods (hyperbaric oxygen, low-intensity pulsed ultrasound, extracorporeal shockwave therapy), (6) biomaterials (fixation methods, biological coatings, biosynthetic bone substitutes, osteoconductive materials), and (7) gene therapy. All of them have shown good results in experimental studies; however, the clinical studies on BA published so far are highly heterogeneous and have a low degree of evidence. The most widely used technique to date is platelet-rich plasma. My position is that orthopedic surgeons must be very cautious when considering using PRP or other BA methods in ACLR.

Abstract
The main complications of surgical reconstruction of multiligament injuries of the knee joint are residual or recurrent instability, arthrofibrosis, popliteal artery injury, common peroneal nerve injury, compartment syndrome, fluid extravasation, symptomatic heterotopic ossification, wound problems and infection, deep venous thrombosis, and revision surgery. Careful surgical planning and execution of the primary surgical reconstruction of multiligament injuries of the knee joint can minimize the risk of the aforementioned complications. Careful postoperative follow-up is required to detect complications. Early recognition and prompt treatment are of paramount importance. To obtain good results in the revision surgery of failed multiligamentary knee reconstructions, it is crucial to perform a thorough and exhaustive evaluation to detect all the causes of failure. Addressing all associated injuries during revision surgery will lead to the best possible subjective and objective results, although functional outcomes are often modest. However, advanced age and high-energy injuries have been associated with the poorest functional outcomes after revision surgery of failed multiligament injuries of the knee joint.

Abstract
Pseudoaneurysms in hemophilic patients are unusual. We must have a suspicion when the patient has suffered an arterial trauma (following arthroscopy, total joint replacement and other surgical operations). Pseudoaneurysms may take place in any anatomical zone where there has been trauma. The diagnosis must be verified by duplex ultrasonography (US), standard angiogram, computed tomography angiogram or magnetic resonance angiography. There are diverse alternatives for the management of arterial pseudoaneurysms. Small pseudoaneurysms can be solved with conservative noninterventional management. It includes outside pressing, US probe pressing or US-guided thrombin injections. In larger pseudoaneurysms, endovascular methods, such as coil embolization, are now preferred. If the aforesaid methods are unsuccessful, standard surgical management with simple ligation or arterial reconstruction must be carried out. We must suspect a pseudoaneurysm when, following an arterial trauma, there is severe bleeding that does not stop with appropriate management with intravenous injection of the insufficient coagulation factor. The diagnosis has to be verified by imaging. Endovascular methods, such as coil embolization, are now preferred by the majority of physicians. The diagnosis and managment of an arterial pseudoaneurysm must be carried promptly to avert adverse events.

Abstract
BACKGROUND From February 2020 onwards, our country has been hit by the coronavirus severe acute respiratory syndrome-2 (SARS-CoV-2) infection. At a glance, hospitals became overrun and had to reformulate all the assistance guidelines, focusing on the coronavirus disease 2019. One year after the start of the pandemic, we present the results of a morbimortality study.
AIM To analyze how our department was affected by the outbreak in terms of morbimortality, and to analyze demographic data, admission to hospital-related data, and subgroups analyses for patients with hip fractures and polytrauma.
METHODS We designed a study comparing data from patients who were admitted to our unit due to a lower limb fracture or a high energy trauma during the pandemic (from March to April 2020) to those admitted during the same period in 2019 before the pandemic. during the pandemic situation. Both cohorts completed a minimum of 6 mo of follow-up.
RESULTS The number of patients admitted to hospital in 2020 was nearly half of those in 2019. Hip fractures in the elderly represented 52 out of 73 of the admitted patients. Twenty patients had a positive test result for SARS-CoV-2 infection. Patients with SARS-CoV-2 infection were admitted to the hospital for a longer time than the non-infected (P < 0.001), and had a higher mortality rate during hospitalization and follow-up (P = 0.02). Patients with a hip fracture associated with a severe respiratory syndrome were mostly selected for conservative treatment (P = 0.03).
CONCLUSION Mortality and readmission rates were higher in the 2020 cohort and during follow-up, in comparison with the cohort in 2019.

Abstract
Biofilm-related implant infections (BRII) are a disastrous complication of both elective and trauma orthopaedic surgery and occur when an implant becomes colonised by bacteria. The definitive treatment to eradicate the infections once a biofilm has established is surgical excision of the implant and thorough local debridement, but this carries a significant socioeconomic cost, the outcomes for the patient are often poor, and there is a significant risk of recurrence. Due to the large volumes of surgical procedures performed annually involving medical device implantation, both in orthopaedic surgery and healthcare in general, and with the incidence of implant-related infection being as high as 5%, interventions to prevent and treat BRII are a major focus of research. As such, innovation is progressing at a very fast pace; the aim of this study is to review the latest interventions for the prevention and treatment of BRII, with a particular focus on implant-related approaches.

Abstract
The reported dissatisfaction rate after primary total knee arthroplasty (TKA) ranges between 15% and 25%. The purpose of this article is to perform a narrative review of the literature with the aim of answering the following question: What are the main factors contributing to patient dissatisfaction after TKA? A review of the literature was performed on patient satisfaction after TKA. The search engines used were MedLine (PubMed) and the Cochrane Library. The keywords used were "TKA" and "satisfaction". The main reported preoperative factors positively contributing to patient satisfaction were the following: fulfilment of preoperative expectations, preoperative complete joint space collapse, increasing patellar and lateral compartment osteophyte size, and TKA communication checklist. The principal preoperative factors negatively contributing to patient satisfaction included female sex, comorbidities, and Hispanic race. The chief perioperative factor positively contributing to patient satisfaction was cosmetic closure, whereas the fundamental perioperative factors negatively contributing to patient satisfaction included joint laxity, anterior tibial component slope, and greater femoral component valgus angle. The principal postoperative factors positively contributing to patient satisfaction were the following: ameliorated walking distance, improved range of motion, and improvements in pain. The most important postoperative factors negatively contributing to patient satisfaction included poor postoperative knee stability and soft-tissue balance, functional limitation, surgical complication and reoperation, staff or quality of care issues, and increased stiffness.

Abstract
Hemophilia is a monogenic mutational disease affecting coagulation factor VIII or factor IX genes. The palliative treatment of choice is based on the use of safe and effective recombinant clotting factors. Advanced therapies will be curative, ensuring stable and durable concentrations of the defective circulating factor. Results have so far been encouraging in terms of levels and times of expression using mainly adeno-associated vectors. However, these therapies are associated with immunogenicity and hepatotoxicity. Optimizing the vector serotypes and the transgene (variants) will boost clotting efficacy, thus increasing the viability of these protocols. It is essential that both physicians and patients be informed about the potential benefits and risks of the new therapies, and a register of gene therapy patients be kept with information of the efficacy and long-term adverse events associated with the treatments administered. In the context of hemophilia, gene therapy may result in (particularly indirect) cost savings and in a more equitable allocation of treatments. In the case of hemophilia A, further research is needed into how to effectively package the large factor VIII gene into the vector; and in the case of hemophilia B, the priority should be to optimize both the vector serotype, reducing its immunogenicity and hepatotoxicity, and the transgene, boosting its clotting efficacy so as to minimize the amount of vector administered and decrease the incidence of adverse events without compromising the efficacy of the protein expressed.

Abstract
The number of rotating-hinge total knee arthroplasties (RH-TKAs) is increasing. As a result, the number of complications related to these procedures will also increase. RH-TKAs have the theoretical advantage of reducing bone implant stresses and early aseptic loosening. However, these implants also have complication rates that cannot be ignored. If complications occur, the options for revision of these implants are limited. Dislocation of RH-TKAs is rare, with an incidence between 0.7% and 4.4%. If it occurs, this complication must be accurately diagnosed and treated quickly due to the high incidence of neurovascular complications. If the circulatory and neurological systems are not properly assessed or if treatment is delayed, limb ischemia, soft tissue death, and the need for amputation can occur. Dislocation of a RH-TKA is often a difficult problem to treat. A closed reduction should not be attempted, because it is unlikely to be satisfactory. In addition, in patients with dislocation of a RH-TKA, the possibility of component failure or breakage must be considered. Open reduction of the dislocation should be performed urgently, and provision should be made for revision (that is, the necessary instrumentation should be available) of the RH-TKA, if it proves necessary. The mobile part that allows rotation can have various shapes and lengths. This variance in design could explain why the reported outcomes vary and why there is a probability of tibiofemoral dislocation.

Abstract
In aseptic tibial diaphyseal nonunions after failed conservative treatment, the recommended treatment is a reamed intramedullary (IM) nail.Typically, when an aseptic tibial nonunion previously treated with an IM nail is found, it is advisable to change the previous IM nail for a larger diameter reamed and locked IM nail (the rate of success of renailing is around 90%).A second change after an IM nail failure is also a good option, especially if bone healing has progressed after the first change.Fibular osteotomy is not routinely advised; it is only recommended when it interferes with the nonunion site.In delayed unions before 24 weeks, IM nail dynamization can be performed as a less invasive option before deciding on a nail change.If there is a bone defect, a bone graft must be recommended, with the gold standard being the autologous iliac crest bone graft (AICBG).A reamer-irrigator-aspirator (RIA) system might also obtain a bone autograft that is comparable to AICBG.Although the size of the bone defect suitable to perform bone transport techniques is a controversial issue, we believe that such techniques can be considered in bone defects > 3 cm.Non-invasive therapies and biologic therapies could be applied in isolation for patients with high surgical risk, or could be used as adjuvants to the aforementioned surgical treatments.

Abstract
BACKGROUND Blood transfusion rates after total knee arthroplasty (TKA) in patients without hemophilia have diminished with the use of a standardized multimodal blood loss prevention method (MBLPM) that includes intra-articular tranexamic acid (TXA) (MBLPM-TXA). However, the topic has not been addressed in people with hemophilia. QUESTIONS/PURPOSES Our aim was to investigate whether the MBLPM-TXA prevents blood loss in patients with hemophilia A who undergo TKA, thereby decreasing the need for post-operative blood transfusion. METHODS This retrospective case-control comparative study involved 30 TKA patients who had a severe degree of hemophilia A without inhibitions: one group treated with the MBLPM-TXA (n = 15) and a second group treated without it (n = 15). In all cases, the pre-operative hemoglobin level was greater than 13 g/dL. RESULTS The MBLPM-TXA group had a transfusion rate of zero, whereas 46.6% of the patients (seven of 15) in the non-MBLPM-TXA group needed transfusion. CONCLUSION This retrospective case-control study showed that the use of an MBLPM-TXA in patients with hemophilia A who underwent TKA was effective in reducing rates of transfusion. We recommend its use.

Abstract
: In hemophilic patients methods are needed to better diagnose joint damage early, so that treatments can be adjusted to slow the progression of hemophilic arthropathy. The aim of this study is to investigate the relationship between the Hemophilia Joint Health Score version 2.1 (HJHS 2.1) and hemophilia early arthropathy detection with ultrasound (HEAD-US) scales, as well as each of their individual items, to better understand the value each provides on the joint condition of patients with hemophilia. The study included data from patients with hemophilia older than 16 years of age, who attended a routine check-up. HJHS 2.1 and HEAD-US assessments were performed on the elbows, knees and ankles. We studied the correlations and agreements between the two scales and analyzed the relationship between the various items of the HJHS 2.1 (inflammation, duration, atrophy, crepitation, flexion deficit, extension deficit, pain, strength, gait) and HEAD-US (synovitis, cartilage and bone). The study included 203 joints from 66 patients with hemophilia (mean age, 34 years). We found a good correlation between the two scales (r = 0.717). However, HJHS 2.1 revealed only 54% of the cases with synovitis and 75% of the cases with osteochondral damage. HEAD-US detected several relevant physical and functional aspects in less than 53% of the cases. HJHS 2.1 and HEAD-US provide complementary data on joint disease in adults with hemophilia; both assessments should therefore, be made available. HEAD-US presented the added value of detecting early joint changes (synovitis and osteochondral damage), while HJHS 2.1 showed the added value of detecting relevant physical and functional changes.

Abstract
INTRODUCTION The coronavirus disease 2019 (COVID-19) pandemic represents an unprecedented global health crisis. To combat its effects, many governments have opted for strategies of social isolation that involve a radical change in people's behavior. AREAS COVERED For patients with hemophilia, the negative consequences of these measures can be greater, given they modify aspects of health care and lifestyles needed to counteract the adverse effects of hemophilia. The long-term consequences of the pandemic on patients with hemophilia are not well known. The aim of this special report is to show what COVID-19 could mean for this population, beyond the risk of infection. EXPERT OPINION Considerations of the clinical, care, therapeutic, physical, nutritional, mental health, pain, and disability aspects that might be affected are included. Strategies are also suggested to minimize the effects that these issues can have on patients' lives. Patients, health professionals, and society as a whole must work together to mitigate the effects of the pandemic on people with hemophilia.

Abstract
The use of an external fixator (EF) in the emergency department (ED) or the emergency theatre in the ED is reserved for critically ill patients in a life-saving attempt. Hence, usually only fixation/stabilization of the pelvis, tibia, femur and humerus are performed. All other external fixation methods are not indicated in an ED and thus should be performed in the operating room with a sterile environment. Anterior EF is used in unstable pelvic lesions due to anterior-posterior compression, and in stable pelvic fractures in haemodynamically unstable patients. Patients with multiple trauma should be stabilized quickly with EF. The C-clamp has been designed to be used in the ED to stabilize fractures of the sacrum or alterations of the sacroiliac joint in patients with circulatory instability. Choose a modular EF that allows for the free placement of the pins, is radiolucent and is compatible with magnetic resonance imaging (MRI). Planning the type of framework to be used is crucial. Avoid mistakes in the placement of EF.

Abstract
Some authors have reported that outpatient total knee arthroplasty (TKA) is a successful, safe and cost-effective treatment in the management of advanced osteoarthritis. The success obtained has been attributed to the coordination of the multidisciplinary team, standardized perioperative protocols, optimal hospital discharge planning and careful selection of patients. One study has demonstrated a higher risk of perioperative surgical and medical outcomes in outpatient TKA than inpatient TKA, including component failure, surgical site infection, knee stiffness and deep vein thrombosis. There remains a lack of universal criteria for patient selection. Outpatient TKA has thus far been performed in relatively young patients with few comorbidities. It is not yet clear whether outpatient TKA is worth considering, except in very exceptional cases (young patients without associated comorbidities). Outpatient TKA should not be generally recommended at the present time.

Rodriguez-Merchan EC. Tranexamic acid is effective in decreasing postoperative intraarticular bleeding in arthroscopic knee surgery. Blood Coagul Fibrinolysis 2020; 31:175-8.

Abstract
: Arthroscopic knee surgery to perform partial meniscectomy and anterior cruciate ligament (ACL) reconstruction is frequent and effective, although a possible complication is postoperative hemarthrosis. When intraarticular bleeding occurs, in addition to the associated pain, the patient usually requires joint aspiration (arthrocentesis) to avoid loss of range of motion (ROM). Sometimes this complication ends up associated with a poor result of surgery due to a loss of ROM. The aim of this narrative review of the literature is to attempt to clarify whether tranexamic acid (TXA) should be utilized in arthroscopic ACL reconstruction and arthroscopic meniscectomy and by what route (intraarticular or intravenous). A number of studies seem to favor the use of intravenous TXA in patients undergoing ACL reconstruction and arthroscopic synovectomy to diminish articular postoperative bleeding and its consequences (pain, swelling, loss of ROM, and the need for arthrocentesis). Regarding the use of intraarticular TXA, one in-vitro study has indicated that TXA in high concentrations is cytotoxic to chondrocytes. Common sense leads me to conclude that until better designed studies can confirm that intraarticular TXA is not cytotoxic to chondrocytes, its use should not be advised. Currently, for patients undergoing arthroscopic ACL reconstruction and arthroscopic meniscectomy, it seems safer to use intravenous TXA.

Abstract
It is clear that the stiff total knee arthroplasty (TKA) is a multifactorial entity associated with preoperative, intraoperative and postoperative factors. Management of the stiff TKA is best achieved by preventing its occurrence using strategies to control preoperative factors, avoid intraoperative technical errors and perform aggressive, painless postoperative physical medicine and rehabilitation; adequate pain control is paramount in non-invasive management. Careful attention to surgical exposure, restoring gap balance, minimizing surgical trauma to the patellar ligament/extensor mechanism, appropriate implant selection, pain control and adequate physical medicine and rehabilitation (physiotherapy, Astym therapy) all serve to reduce its incidence. For established stiff TKA, there are multiple treatment options available including mobilization under anaesthesia (MUA), arthroscopic arthrolysis, revision TKA, and combined procedures.

Abstract
Background: In general, chronic problems of soft tissues (muscles, tendons, ligaments) are due to scarring or degeneration. Astym therapy (Performance Dynamics, Inc. Muncie, Indiana) has been reported to address tendinopathy by stimulating regeneration in soft tissues (muscles, tendons, ligaments) and the resorption of unwanted scar tissue that causes pain and limits mobility.Purpose: To analyze the effectiveness of Astym therapy in the treatment of musculoskeletal problemsMethods: A narrative review of the literature on the topic was carried out. A Cochrane Library and PubMed (MEDLINE) search related to the role of Astym therapy was analyzed. The only language searched was English. Scientific meeting abstracts and other sources of evidence were not considered. The main criteria for selection were articles that were focused on the role of Astym therapy.Results: Astym therapy seems to be useful for the treatment of chronic ankle sprains, Achilles tendon tendinopathy, hamstring tendinopathy, elbow tendinopathy, and the stiff total knee arthroplasty. Astym therapy also appears to be useful to gain range of motion, muscle strength, and function in patients with cerebral palsy, and after mastectomy.Conclusions: Astym therapy seems to activate a regenerative response in degenerative tendinopathy and eliminate or reduce the scar tissue/fibrosis that causes pain and limitation of mobility. Based on the positive findings of the emerging published research further study is warranted to confirm the benefits of Astym therapy on a variety of musculoskeletal disorders.
