Hip arthroscopy is a rapidly evolving field in terms of indications, prognostic factors and surgical technique. The most common indication for hip arthroscopy is femuro-acetabular impingement. Femuro-acetabular impingement (FAI) may produce symtoms of pain in association with athletic activity or in daily life. FAI is caused by osteophytes on the cervikal head-neck junction (cam) or at the acetabular edge (pincer). Treatment of femuro-acetabular impingement includes resection of the impinging osteophytes, preferably using arthroscopic technique. In Sweden, research is performed in order to clarify possible causes of FAI and to prospectively evaluate the outcome of hip arthroscopy.

Hide Abstract
An acute Achilles tendon rupture is a common sports-related injury in middle-aged men. The diagnosis is always clinical and it is very important that the diagnosis is not missed or delayed. The time period for tendon healing and rehabilitation is long and commonly results in functional deficits. Only half of the patients return to the preinjury lev-el of physical activity. There is no consensus in terms of the optimal treatment for patients with acute Achilles tendon rupture. Both surgical and non-surgical treatment with modern rehabilitation protocols are valid alternatives in the clinical day-by-day work. There is a need for future studies to optimize the treatment and identify predictors in order to individualize the optimal treatment.

Hide Abstract
Anterior cruciate ligament (ACL) injury is a common injury and is often associated with concomitant injuries to the menisci and cartilage and, in the long term, osteoarthritis. Preventive training programs have shown to be highly effective in terms of reducing the risk for ACL injury in sports. ACL reconstruction is indicated when the patient experiences symtoms of instability (»giving way«) despite rehabilitation with a physiotherapist aiming to gain neuromuscular control of the knee. Early ACL reconstruction may be indicated, for example when the patient desires to return to pivoting contact-sports at high level. Modern surgical technique for ACL reconstruction has evolved rapidly and includes »anatomic reconstruction« and individualized treatment, where each patient's unique anatomy, injury and requests on knee function are taken into consideration. In Sweden, more than 90% of all ACL reconstructions performed are included into the Swedish National ACL Register.

Hide Abstract
Achilles tendinopathy is a clinical syndrome characterized by a combination of pain, swelling, morning stiffness and difficulty with physical activity. This is a common overuse injury in sports that include running and jumping. The recovery from Achilles tendinopathy can take between 3 and 12 months. Exercise as treatment has the highest level of evidence and should consist of both concentric and eccentric exercises. For exercises to give a favorable outcome, they are allowed to cause pain and should be performed daily. The use of a pain-monitoring model helps with the balance between overloading and loading enough to achieve a positive response to the exercises. Other treatments, such as injection therapies, shock wave treatment, laser treatment and ultrasound treatment, have not been consistently found to be beneficial but might be useful in conjunction with the exercise treatment.

Hide Abstract
The pivot shift test is the only physical examination test capable of predicting knee function and osteoarthritis development after an ACL injury. However, because interpretation and performance of the pivot shift are subjective in nature, the validity of the pivot shift is criticized for not providing objective information for a complete surgical planning for the treatment of rotatory knee laxity. The aim of ACL reconstruction was eliminating the pivot shift sign. Many structures and anatomical characteristics can influence the grading of the pivot shift test and are involved in the genesis and magnitude of rotatory instability after an ACL injury. The objective quantification of the pivot shift may be able to categorize knee laxity and provide adequate information on which structures are affected besides the ACL. A new algorithm for rotational instability treatment is presented, accounting for patients' unique anatomical characteristics and objective measurement of the pivot shift sign allowing for an individualized surgical treatment.

Evidence to support the interpretation and use of the Anatomic Anterior Cruciate Ligament Reconstruction Checklist.
J Bone Joint Surg Am
PUBLISHED: 10-18-2013
Show Abstract
Hide Abstract
Published papers on anatomic anterior cruciate ligament (ACL) reconstruction often lack details in the description of the surgical procedure, and there are large variations in anatomic ACL reconstruction techniques. We aimed to develop a validated checklist to be used for anatomic ACL reconstruction. First, a list of all potential items that could be used in the checklist was generated. Thirty-four ACL experts were selected to participate in an anonymous online survey to rate the importance of these items on a scale of 1 to 4 (with a score of 4 having the most importance). The results were verified by surveying a large sample of 959 orthopaedic specialists who are peer reviewers for four major orthopaedic journals. Items were included in the final checklist if they received an importance score of 3 or 4 from at least 75% of the survey takers. The survey response rate was 79% (twenty-seven of thirty-four) of the ACL experts and 40% (379 of 959) of the peer reviewers. The final Anatomic ACL Reconstruction Checklist includes seventeen items with a maximum score of 19 points. The final checklist underwent preliminary testing for internal consistency, intertester reliability, and validity. Cronbachs alpha for internal consistency was 0.82, and the intraclass correlation coefficient (ICC) for intertester reliability was 0.65. This large survey-based study on anatomic ACL reconstruction resulted in the development of the Anatomic ACL Reconstruction Checklist; preliminary evidence for interpretation of the scores is provided.

Hide Abstract
PURPOSE: To understand orthopedic surgeons views, preferences, and awareness on "treatment gap" and various conservative and surgical treatments for early to mid-stage knee osteoarthritis (OA). METHODS: A self-administered questionnaire on the treatment of knee OA was developed in collaboration with orthopedic surgeons with extensive research experience and methodological expertise. The survey was distributed electronically to a group of international orthopedic surgeons and surgical trainees. The data were collected, reviewed, and analyzed using descriptive statistics. RESULTS: One hundred and seventy-three surgeons and surgical trainees completed the survey. The respondents reported that about 58 % of the patients they treat have early to mid-stage knee OA (Kellgren and Lawrence grade I-III). There were significantly higher usage of medications and lower usage of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) (P < 0.05) in developing countries than in developed countries. Four of five surgeons (84 %) perceived a need for better treatments for younger (<60 years old) physically active OA patients in which UKA or TKA is not indicated. Most respondents (80 %) would be willing to adjust age/activity threshold for surgery if a procedure was reversible and recovery was minimal. Two of three surgeons (68.4 %) perceived a treatment gap for early knee OA. However, effective treatments for patients within the treatment gap would have substantial positive social, and economic impacts. CONCLUSION: The study suggests an ongoing treatment gap for patients with early knee OA and the need for better evidence to guide practice.

Evaluation of injured-knee laxity is essential for treatment selection, clinical follow-up, and research. Interest in rotatory knee laxity increased with implementation of anatomic anterior cruciate ligament reconstruction. The pivot shift test represents a link between static testing with 1° of freedom and dynamic testing during functional activity. Difficulties lie in standardizing the performance of the pivot shift test and extracting measurable and relevant kinematic data. Noninvasive methodologies based on electromagnetic or acceleration sensors can evaluate the pivot shift in a quantitative and reliable manner. Further validation and reliability testing of devices for examination of rotatory laxity is warranted.

Show Abstract
Hide Abstract
In this article, we discuss current topics for rotatory knee laxity. All tests for knee laxity have a value. Static knee laxity tests reveal information for each individual patients laxity status, especially compared to the contralateral side. Static knee laxity tests are simple to do, and some of them are instrumented, therefore quantifiable. Dynamic knee laxity tests are more complex. Dynamic stereo radiography (DSX) is considered the gold standard. Utilizing DSX, information can be gained on 3-D kinematics, functional joint space, and joint contact patterns. The disadvantage is that DSX is expensive and can only be performed in a laboratory environment. The pivot shift test is a unique test, because it is dynamic and easily performed in the office. However, it is subjective and only recently quantifiable. Future endeavors will attempt to improve the value of the pivot shift test by standardizing the test and improving measurement technologies, while keeping the pivot shift test simple and non-invasive.

Anatomic single- and double-bundle anterior cruciate ligament reconstruction, part 2: clinical application of surgical technique.
Am J Sports Med
PUBLISHED: 05-21-2011
Show Abstract
Hide Abstract
The anterior cruciate ligament has been and is of great interest to scientists and orthopaedic surgeons worldwide. Anterior cruciate ligament reconstruction was initially performed using an open approach. When the approach changed from open to arthroscopic reconstruction, a 2- and, later, 1-incision technique was applied. With time, researchers found that traditional arthroscopic single-bundle reconstruction did not fully restore rotational stability of the knee joint and a more anatomic approach to reconstruct the anterior cruciate ligament has been proposed. Anatomic anterior cruciate ligament reconstruction intends to replicate normal anatomy, restore normal kinematics, and protect long-term knee health. Although double-bundle anterior cruciate ligament reconstruction has been shown to result in better rotational stability in both biomechanical and clinical studies, it is vital to differentiate between anatomic and double-bundle anterior cruciate ligament reconstruction. The latter is merely a step closer to reproducing the native anatomy of the anterior cruciate ligament; however, it can still be done nonanatomically. To evaluate the potential benefits of reconstructing the anterior cruciate ligament in an anatomic fashion, accurate, precise, and reliable outcome measures are needed. These include, for example, T2 magnetic resonance imaging mapping of cartilage and quantification of graft healing on magnetic resonance imaging. Furthermore, there is a need for a consensus on which patient-reported outcome measures should be used to facilitate homogeneous reporting of outcomes.

Anterior cruciate ligament graft fixation--a myth busted?
Arthroscopy
PUBLISHED: 04-08-2010
Show Abstract
Hide Abstract
Anterior cruciate ligament graft fixation has become one of the most investigated topics in the sports traumatology literature. With over 400 publications within the past decade, a plausible explanation for the popularity of the topic would be that anterior cruciate ligament graft fixation represents an obvious clinical problem. Yet this does not seem to be the case. We set out to analyze the veracity of the notion that the fixation site is the weak link in a reconstructed knee in the early postoperative period. A mere temporal association is found between the first clinical reports on increased anterior tibial translation relative to the femur with soft-tissue grafts and the first pullout studies reporting lower ultimate failure loads with such grafts. This association was sufficient to convince the orthopaedic community at large that actual causality exists between soft-tissue graft fixation failure and increased knee laxity during healing. Thus the concept of "graft slippage" was born. Even with the imminent risk of being misconstrued as contentious, we submit that the entire concept of graft slippage is a myth, founded on poor scientific practice and affected by commercial bias. As a way forward, clinically important phenomena should be demonstrated through experiments with clear and sound clinical endpoints. As for preclinical studies, although they are indisputably helpful in the elaboration of such phenomena, serious hazards lie in declaring them a sufficient scientific basis for new research or, worse, for clinical standards of care. More importantly, no matter how sophisticated or fascinating their methodology, preclinical studies do not relieve us from the necessity and duty of proving our theories, whenever possible, with randomized controlled trials.

Hide Abstract
Internal impingement syndrome is a painful shoulder condition related to the impingement of the soft tissue, including the rotator cuff, joint capsule and the long head of the biceps tendon and glenoid labrum. Two types of internal impingement syndrome can be differentiated: posterior-superior impingement and anterior-superior impingement (ASI). The aetiology of ASI in particular is not clear. The purpose of this paper is to discuss the different aetiological theories relating to ASI, try to clarify the clinical, radiological and arthroscopic findings and, finally, suggesting treatment for this complex shoulder syndrome.

Hide Abstract
The aim of this investigation was to evaluate the long-term outcome of arthroscopic subacromial decompression (ASD) in patients with primary impingement syndrome stage II and early stage III. Ninety-five patients (105 shoulders, 48 female), mean age 54 years (range 26-69), who had undergone surgery between 1996 and 1999, were included. Pain intensity during activity and at rest, patient satisfaction, active range of motion (ROM), muscular strength and shoulder function using the Constant score were evaluated. Fifty-three (50%) shoulders were pain-free (Visual Analogue Scale < or = 10 mm) during activity and 72 (68%) shoulders were pain-free at rest. Sixty-one (58%) patients stated that they were very satisfied and 27 (25%) were quite satisfied with regard to their current shoulder function. Shoulders were divided into Group 1: Pain-free patients (n = 53), Group 2: Patients with shoulder pain and no arthropathy (n = 41) and Group 3: Patients with shoulder pain and arthropathy (n = 11). The groups had average active ROM of 157 degrees, 135 degrees and 117 degrees, respectively, in abduction and 97 degrees, 79 degrees, and 68 degrees in external rotation. The average strength in elevation in the scapular plane was 7.4, 5.8 and 3.9 kg, respectively, whereas the mean value in external rotation was 8.4, 7.9 and 5.3 kg, respectively. The Constant score had a mean value of 87, 69 and 59 points in the three groups, respectively. Eleven shoulders have undergone re-operation, one after a new trauma. We conclude that ASD is a valuable procedure. Patients expressed a high degree of satisfaction with shoulder function 8-11 years after ASD.

A new measurement of heel-rise endurance with the ability to detect functional deficits in patients with Achilles tendon rupture.

Hide Abstract
Studies evaluating treatment effects on muscle function after an Achilles tendon rupture often use various tests for evaluating calf muscle strength. However, these tests rarely demonstrate the difference between treatment groups; therefore, new tests with a higher ability to detect possible differences in outcome are needed. The purpose of this study was to evaluate the validity and ability to detect differences in outcome of a heel-rise work test that would measure both the height of each heel-rise and the number of repetitions. Seventy-eight patients (65 men and 13 women) at a mean (standard deviation) age of 42 (9) years with Achilles tendon ruptures were included. The patients were evaluated with the new heel-rise test at 6 and 12 months after injury. The limb symmetry index (LSI = involved/uninvolved x 100) was calculated to determine the size of the difference in function between the injured and the uninjured side. The heel-rise height differed significantly between the injured and uninjured sides at the 6- and 12-month evaluations (P < 0.001). At the 6-month evaluation, the patients had achieved a mean LSI of 84% on the number of repetitions parameter but only a mean LSI of 61% on the work parameter. At the 12-month evaluation the mean, LSI of the heel-rise repetition parameter was 95%, indicating that the patients had fully recovered function, but on the work parameter the mean LSI was only 76%. The heel-rise work test in the present study has good validity and greater ability to detect differences between the injured and the uninjured sides than a test that measures only the number of heel-rise repetitions in patients with Achilles tendon rupture.

Hide Abstract
The aims of the study were to analyse the change in knee laxity over time after anterior cruciate ligament (ACL) reconstruction, using either bone-patellar-tendon-bone (BPTB) or hamstring (HS) tendon autografts, and to compare the knee laxity measurements between the study groups both pre-operatively and on multiple follow-up occasions. Another aim was to compare the radiographic findings in terms of degenerative changes between the study groups. A randomised series of 71 patients, who underwent ACL reconstruction using BPTB or HS tendon autografts and interference screw fixation, were included in the study. Of these patients, 47/71 (66%) attended a clinical examination, including laxity measurements using the KT-1000 arthrometer, pre-operatively and on four post-operative occasions; 6 months, 1 year, 2 years and 7 years after the reconstruction. The BPTB group consisted of 22 patients, while there were 25 patients in the HS group. There were no significant differences in the mean side-to-side knee laxity between the BPTB and the HS group pre-operatively or at the follow-up examinations. There was a tendency towards a reduction in side-to-side knee laxity over time in both groups, measured with the KT-1000 arthrometer. The decrease was significant when analysing the injured and uninjured knee separately (injured side p < 0.001 (BPTB) and p = 0.005 (HS), uninjured side p = 0.008 and p = 0.042, respectively). Forty-four patients (BPTB 21, ST 23) underwent a radiographic assessment at the 7-year follow-up, which revealed no significant differences between the study groups in terms of osteoarthritic findings classified according to the Fairbank and Ahlbäck rating systems. In overall terms, osteoarthritis was identified in 16% (BPTB 19%; ST 13%; n.s.) according to the Ahlbäck rating system and 68% (BPTB 67%; ST 70%; n.s.) according to the Fairbank rating system. There were no significant differences in knee laxity measurements between the two study groups pre-operatively or at 7 years. A decrease in knee laxity over time was seen in both groups. There were no significant differences between the BPTB and ST groups in terms of osteoarthritic findings at 7 years.

High incidence of deep venous thrombosis after Achilles tendon rupture: a prospective study.

PUBLISHED: 01-16-2009
Show Abstract
Hide Abstract
Deep venous thrombosis (DVT) is common after lower limb injury, but the effect of prophylactic treatment has not been documented in large randomised trials or meta-analyses. As a result, evidence-based recommendations have not been established. The purpose of this study was to evaluate the incidence of venous thromboembolism in patients with Achilles tendon rupture. A total of 100 consecutive patients with an acute Achilles tendon rupture were included in a prospective study and randomised to either surgical or non-surgical treatment. At 8 weeks after the initiation of treatment, 95/100 patients were screened for DVT using colour duplex sonography (CDS) with blinded interpretation by two experienced examiners and adjudication in cases of disagreement by a third person. A total of 95 patients (79 male and 16 female) with a median (range) age of 41 (24-63) years were screened for CDS at 8 weeks. Of the 95 patients, 32 had a CDS-verified thrombosis, 5 proximal and 27 distal, whereas 3 had non-fatal pulmonary embolism. Surgical treatment was performed in 49 patients, non-surgical in 46. There were no significant differences in DVT frequency between the two treatment groups. The incidence of asymptomatic and symptomatic deep venous thrombosis is high after Achilles tendon rupture and there is a need to define the possible benefit of thromboprophylaxis.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
