Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function. 展开更多

Acetabular fractures in the geriatric population are typically low-energy fractures resulting from a fall from standing height.Compromised bone quality in the elderly,as well as this population’s concomitant medical comorbidities,render the management of such fractures challenging and controversial.Non-operative management remains the mainstay of treatment,although such a choice is associated with numerous and serious complications related to both the hip joint as well as the general condition of the patient.On the other hand,operatively treating acetabular fractures(e.g.,with osteosynthesis or total hip arthroplasty)is gaining popularity.Osteosynthesis can be performed with open reduction and internal fixation or with minimally invasive techniques.Total hip arthroplasty could be performed either in the acute phase combined with osteosynthesis or as a delayed procedure after a period of non-operative management or after failed osteosynthesis of the acetabulum.Regardless of the implemented treatment,orthogeriatric co-management is considered extremely crucial,and it is currently one of the pillars of a successful outcome after an acetabular fracture. 展开更多

Clavicle fractures are frequent orthopedic injuries,often resulting from direct trauma or a fall.Most clavicle fractures are treated conservatively without any complications or adverse effects.Concomitant injuries of the subclavian vein or artery are rarely encountered and most commonly associated with high-energy trauma or comminuted clavicle fractures.They are potentially life-threatening conditions leading to hemorrhage,hematoma,pseudoaneurysm or upper limb ischemia.However,the clinical presentation might be obscure and easily missed,particularly in closed and minimally displaced clavicular fractures,and timely diagnosis relies on early clinical suspicion.Currently,computed tomography angiography has largely replaced conventional angiography for the assessment of subclavian vessel patency,as it demonstrates high accuracy and temporal resolution,acute turnaround time,and capability of multiplanar reconstruction.Depending on the hemodynamic stability of the patient and the severity of the injury,subclavian vessel lesions can be treated conservatively with observation and serial evaluation or operatively.Interventional vascular techniques should be considered in patients with serious hemorrhage and limb ischemia,followed by stabilization of the displaced clavicle fracture.This review aims to provide a comprehensive overview of the incidence,clinical presentation,diagnostic approaches,and current management strategies of clavicle fractures associated with subclavian vessel injuries. 展开更多

BACKGROUND Tibial tubercle osteotomy(TTO) is a well-established surgical technique to deal with a stiff knee in revision total knee arthroplasty(RTKA). However, several reports have described potential osteotomy-related complications such as nonunion, tibial tubercle migration and fragmentation, and metalware related pain.AIM To evaluate the literature and estimate the efficiency of TTO in RTKA in terms of osteotomy union, knee mobility and complications.METHODS MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials were investigated for completed studies until February 2020. The principle outcome of the study was the incidence of union of the osteotomy. Secondary outcomes were the knee range of motion as well as the TTO-related and overall procedure complication rate.RESULTS Fifteen clinical studies with a total of 593 TTOs were included. The TTO union rate was 98.1%. Proximal migration and anterior knee pain were the most common TTO-related complications accounting for 6.9% and 6.4% of all cases,respectively. However, only 2.2% of cases suffering from anterior knee pain needed hardware removal. Knee flexion was improved from 82.9° preoperatively to 100.1° postoperatively and total knee range of motion was increased from 73.4° before surgery to 97° after surgery. Stiffness requiring manipulation under anesthesia was recorded in 4.6% of cases. No major complications were reported.CONCLUSION The current systematic review supports the use of TTO in RTKA, as it is associated with high union rate, significant improvement in knee motion and low osteotomy-related complication risk that rarely leads to secondary tibial tubercle procedures. 展开更多

BACKGROUND Arthroscopic procedures are commonly performed for rotator cuff pathology.Repair of rotator cuff tears is a commonly performed procedure.The intraoperative evaluation of the tear size and pattern contributes to the choice and completion of the technique and the prognosis of the repair.AIM To compare the arthroscopic and open measurements with the real dimensions of three different patterns of simulated rotator cuff tears of known size using a plastic shoulder model.METHODS We created three sizes and patterns of simulated supraspinatus tears on a plastic shoulder model(small and large U-shaped,oval-shaped).Six orthopaedic surgeons with three levels of experience measured the dimensions of the tears arthroscopically,using a 5 mm probe,repeating the procedure three times,and then using a ruler(open technique).Arthroscopic,open and computerized measurements were compared.RESULTS A constant underestimation of specific dimensions of the tears was found when measured with an arthroscope,compared to both the open and computerized measurements(mean differences up to-7.5±5.8 mm,P<0.001).No differences were observed between the open and computerized measurements(mean difference-0.4±1.6 mm).The accuracy of arthroscopic and open measurements was 90.5%and 98.5%,respectively.When comparing between levels of experience,senior residents reported smaller tear dimensions when compared both to staff surgeons and fellows.CONCLUSION This study suggests that arthroscopic measurements of full-thickness rotator cuff tears constantly underestimate the dimensions of the tears.Development of more precise arthroscopic techniques or tools for the evaluation of the size and type of rotator cuff tears are necessary. 展开更多

BACKGROUND Development of infrapatellar saphenous neuroma(ISN)is a well-recognized reason for knee pain following total knee arthroplasty(TKA).So far,very few studies have addressed the development of painful ISN after TKA and its impact on functional outcome and patient satisfaction.AIM To present the results of surgical treatment for ISN after primary TKA,the level of pain relief,and the improvement of knee motion and function.METHODS Fifteen patients(13 women,2 men)with persistent medial pain for more than six months after primary TKA,due to osteoarthritis,underwent surgical excision of ISN.ISN diagnosis was confirmed with the presence of Tinel’s sign along the course of the infrapatellar branch of the saphenous nerve and with pain relief after selective nerve block using local anesthetic.Component loosening,malalignment,instability and infection were excluded systematically in all patients as a source of pain.Pain relief in terms of visual analog scale(VAS),active knee range of motion(ROM),and the Knee Society Score(KSS)for pain and function were evaluated preoperatively and at least six months postoperatively.RESULTS The mean patients’age was 71.3±5.4 years old.The mean interval between TKA and neuroma excision was 10 mo(range,6 to 14 mo),while the mean follow-up was 8 mo(range:6 to 11 mo).All 15 patients experienced almost complete immediate pain relief and resolution of allodynia and hyperesthesia after surgery.Pain on the VAS scale improved from 8.6±1.3 preoperatively to 0.8±0.9 at the final follow-up(P=0.001).KSS pain and function scores were improved from 49.3±5.9 and 62.7±12.8 before surgery to 91.8±4.2 and 75.3±11.3 after surgery,respectively(P=0.001 and P=0.015).Active knee ROM was also increased postoperatively from 96±4 to 105±6 degrees(P=0.001).There were no complications and no further operations required.CONCLUSION ISN should be considered a potential cause of persistent pain following TKA.Neuroma excision not only provides immediate pain relief and resolution of symptoms but may also improve the knee range of motion. 展开更多

The anterolateral ligament(ALL)is a primary structure of the anterolateral complex of the knee that contributes to internal rotational stability of the joint.Injury of the ALL is commonly associated with rupture of the anterior cruciate ligament.If left untreated,ALL lesions may lead to residual anterolateral rotational instability of the knee after anterior cruciate ligament reconstruction,which is a common cause of anterior cruciate ligament graft failure.The function of the ALL can be restored by lateral extraarticular tenodesis or anterolateral ligament reconstruction(ALLR).In the lateral extraarticular tenodesis procedure,a strip of the iliotibial band is placed in a non-anatomical position to restrain the internal rotation of the tibia,while in ALLR,a free graft is fixed at the insertion points of the native ALL.Gracilis and semitendinosus grafts have mainly been utilized for ALLR,but other autografts have also been suggested.Furthermore,allografts and synthetic grafts have been applied to minimize donor-site morbidity and maximize the size and strength of the graft.Nevertheless,there has been no strong evidence to fully support one method over another thus far.The present review presents a detailed description of the graft choices for ALLR and the current literature available in regard to the effectiveness and outcomes of published surgical techniques. 展开更多

The musculoskeletal system involves multiple tissues which are constantly exposed to being exposed to various biological and mechanical stimuli.As such,isolating and studying a particular system from a complex human clinical environment is not always a realistic expectation.On top of that,recruitment limitations,in addition to the nature of orthopaedic interventions and their associated cost,sometimes preclude consideration of human trials to answer a clinical question.Therefore,in this mini review,we sought to rationalize the rapid evolution of biomedical research at a basic scientific level and explain why the perception of orthopaedic conditions has fundamentally changed over the last decades.In more detail,we highlight that the number of orthopaedic in vitro publications has soared since 1990.Last but not least,we elaborated on the minimum requirements for conducting a scientifically sound infection-related laboratory experiment to offer valuable information to clinical practitioners.We also explained the rationale behind implementing molecular biology techniques,ex vivo experiments,and artificial intelligence in this type of laboratory research. 展开更多
