RESUMO
PURPOSE: This international survey aimed to evaluate the potential controversies regarding the management of first patellar dislocation amongst experienced knee surgeries in the treatment of the first episode of patellar dislocation without osteochondral fragments. METHODS: An online survey was conducted from February 2021 to December 2021 to assess the global trend in the diagnosis and management of first-time patellar dislocation without osteochondral fragments. The online survey was accessible on the homepage of the website of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA). The questionnaire consisted of multiple-choice questions and was divided into three sections. The first section consisted of eight questions regarding demographic information, professional activity, and responder experience. The second section consisted of 13 questions regarding the approach to a first patellar dislocation (clinical examination, imaging, and rehabilitation). The third section contained 2 questions concerning the relevance of patient characteristics to the therapeutic algorithm (age, sports, and pathoanatomical predisposing risk factors). RESULTS: A total of 438 orthopaedic surgeons worldwide completed the questionnaire. At the first approach to diagnose a first-time patellar dislocation, 251 (57%) of the surgeons requested plain radiographs, and 158 (36%) requested magnetic resonance imaging (MRI). In conservatively treated patients, 368 (84%) of the respondents recommended the use of a knee brace. Amongst them, 14 (3%) advocated its use for one week, 75 (17%) for two weeks, 123 (28%) for three weeks, 105 (24%) for four weeks, and 97 (22%) for six weeks. In conservatively treated patients, 215 (49%) of the surgeons recommended load to tolerance, 148 (34%) recommended 30% to 60% of the bodyweight, and 75 (17%) advised against weight-bearing. More than half of the surgeons considered a patient aged less than 35 years practising contact sports to be a candidate for the medial patello-femoral ligament (MPFL) procedure. In addition, a tibial tuberosity to trochlear groove distance (TT-TG) distance of 15 to > 20 mm (for > 75% of the surgeons) and a trochlea types C and D (for > 70% of the surgeons) were considered possible indications for direct surgical management. CONCLUSION: At the first approach to diagnose a first-time patellar dislocation, plain radiographs and MRI should be performed. In conservatively treated patients, most of the surgeons recommend weight-bearing to tolerance and a knee brace during the first four weeks, with range of motion of full extension to 30° during the first 15 days and up to 60° for an additional 15 days. Surgical management should be performed in patients in the second and third decades of life practising contact sports and in those patients who present types C and D trochlea dysplasia and patella alta. LEVEL OF EVIDENCE: IV.

PURPOSE OF REVIEW: We present the reader with insight on the most common disorders of the knee in newborns and infants. Knee issues in this population may confuse the first contact physicians due to certain peculiarities of the immature immune system, small size and underdevelopment of joint anatomy. Data presented here are recent and significant, and something to bear in mind when caring for children of this age. RECENT FINDINGS: With the advent of new diagnostic methods, a shift in the causative agent of pediatric knee infections has been noted. Minimally invasive methods such as arthrocentesis and arthroscopy are successfully employed in treatment of knee problems in newborns and infants. A trial of conservative therapy in congenital patellar instability can give good results, and obviate the need for surgery in some cases. Various syndromes that affect the knee have specific characteristics that need to be recognized early to avoid problems in the future. SUMMARY: Although rare, knee problems in infants can and do occur. Their cause varies significantly and good outcomes require a multidisciplinary approach. Early diagnosis, referral and initiation of treatment protocols can significantly influence the fate of the joint and with it the patients' functional status for life.

The anterolateral ligament is recently recognized as an important structure in restoring rotational stability of the anterior cruciate ligament-deficient knee. Biomechanical and clinical studies confirmed the benefits of concurrent anterior cruciate ligament and anterolateral ligament reconstruction. However, present techniques mostly use hamstring tendons autografts and therefore additionally disrupt the knee biomechanics. The plantaris tendon is a well known and accessible graft and has excellent biomechanical properties for anterolateral ligament reconstruction. The present paper describes a new combined anterior cruciate ligament and anterolateral ligament reconstruction technique using plantaris tendon and semitendinosus tendon.Level of evidence V (Case report).

BACKGROUND: Osteoid osteoma is a painful benign skeletal tumour of unknown aetiology. Most often it occurs in the long bones of extremities and responds well to nonsteroidal anti-inflammatory medications. However, unusual localization and atypical presentation of this tumour might present a diagnostic challenge, especially if symptoms mimic that indicative of juvenile spondyloarthritis. CASE PRESENTATION: A misdiagnosed ten-and-a-half-year-old girl with osteoid osteoma involving the distal phalanx of a little finger is presented. Her initial symptoms were pain and swelling of the little finger resembling dactylitis, while various imaging modalities showed signs of tenosynovitis, indicating a possible development of juvenile spondyloarthritis. Several trials of different non-steroid anti-inflammatory drugs gave no satisfactory results and ultrasound guided triamcinolone-hexacetonide injection provided only a short relief. Finally, almost three years after initial presentation, persistent clinical symptoms warranted repeated imaging that raised suspicion of an osteoid osteoma. Directed treatment with surgical intervention led to almost immediate and complete resolution of her symptoms. CONCLUSIONS: Osteoid osteoma should be suspected in case of a tender swelling of a digit in children and adolescents, regardless of initial imaging findings and clinical presentation. Early diagnosis and treatment of this benign condition can have a substantial impact on quality of life of patients and their families and protect them from many unnecessary diagnostic procedures and treatment.

Longitudinal epiphyseal bracket (LEB) is a rare bone dysplasia of the tubular bones. Owing to an abnormal secondary ossification center, the affected bones can develop progressive shortening and angular deformity. The aim of our study was to provide an overview of the reported data regarding epidemiology and surgical procedures available for LEB of the first metatarsal bone in a pediatric population combined with a small case series. We report a retrospective case series of 3 nonsyndromic pediatric patients with different ages and with confirmed dysplasia of the first metatarsal bone. All patients presented with unilateral congenital hallux varus deformity and underwent surgical treatment. The radiographs and medical records were reviewed to evaluate the deformity characteristics, treatment, and clinical results. The mean patient age at initial surgery was 34 (range 12 to 63) months, and the median follow-up period was 46 (range 31 to 75) months. Almost all specific radiographic measurements showed correction of the deformity, and each foot demonstrated functional and cosmetic improvement. A standardized literature search was performed to obtain studies of LEB of the first metatarsal bone in the pediatric population. From on our results and the current data available, surgical treatment should be tailored to the patient's age and radiographic stage of LEB. However, monitoring until skeletal maturity of the feet is necessary to assess the final results.

Medial patellofemoral ligament reconstruction is a standard treatment option for patients with patellar instability. The main purpose of this study was to determine whether isolated anatomic medial patellofemoral ligament reconstruction using double folded, four-strand plantaris tendon autograft restores patellar stability in adolescent patients. Plantaris tendon autografts were harvested through proximal approach and used in four adolescent patients. A four-strand autograft was prepared in a double-limbed configuration and fixed on the patella and the femur with suture anchors and interference screws, respectively. The mean Kujala score improved significantly from 44 ± 24 SD (range, 19 to 69) points preoperatively to 94 ± 10 SD (range, 78 to 100) points postoperatively (P< 0.001). All patients reported excellent subjective outcomes and returned to their pre-injury level of sporting activities. The use of a four-strand plantaris tendon autograft in isolated anatomic medial patellofemoral ligament reconstruction can restore patellar stability in adolescents.
RESUMO
BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is a standard treatment option for selected patients with patellar instability. Although frequently performed, the optimal graft source for the procedure has not yet been established. This study aimed to determine whether a two-strand plantaris tendon construct possesses the biomechanical properties needed to act as an MPFL reconstruction graft. METHODS: Thirty paired plantaris and gracilis tendons were harvested from 15 cadavers, mean age at death of 42.7 years. All specimens were frozen and maintained at -20 °C until biomechanical testing. Prior to mechanical testing, specimens were thawed at room temperature. The two-strand plantaris tendon and two-strand gracilis tendon constructs were created and secured in a uniaxial tensile testing machine in a triangular-shaped mode. Biomechanical properties for tensile testing to failure were determined using validated method. Results obtained were compared with the previously published data on native MPFL biomechanical properties. RESULTS: The mean maximal force was 220.3 ± 108.1 N and 448.1 ± 117 N for the two-strand plantaris tendon construct and two-strand gracilis tendon construct, respectively. Significant differences were observed between all biomechanical properties of two-strand plantaris tendon and two-strand gracilis tendon constructs. The mean maximal force of a two-strand plantaris tendon construct and a two-strand gracilis tendon construct were greater than the mean maximal force of the native MPFL reported in all previous studies. CONCLUSIONS: This study suggests that, due to its biomechanical properties, the two-strand plantaris tendon graft is suitable as a graft for MPFL reconstruction.

Tuberculous trochanteric bursitis (TTB) is an extremely rare form of extrapulmonary tuberculosis. Due to a low clinical suspicion and poor collaboration among medical professionals, the diagnosis of TTB can be often delayed. In this report, we describe a case of neglected TTB in an adolescent girl that initially presented with right thigh swelling and fluctuance. The patient underwent repeated unsuccessful surgical treatment; however, dull pain and periodic wound drainage remained for eight years. Complete excision of fistula and trochanteric bursa and one year of oral antituberculous drug therapy led to complete recovery. This case report highlights tuberculosis as a diagnostic challenge, when rare localizations are affected. In addition, this report addresses several diagnostic pitfalls and reviews the literature regarding TTB in adolescent patients. Orthopedic surgeons need to consider TTB, when swelling, fluctuance or repeated wound drainage are present on the thigh.

We report a case of hand soft tissue tumor-proliferative fasciitis (PF)-in a 12-year-old patient that presented as a painful lump causing trigger finger. After meticulous diagnostic workup, a surgical excision led to immediate amelioration of symptoms. PF is a rare benign pseudosarcomatous lesion arising typically in the subcutaneous tissue and fascia in adults. It is very uncommon in the hand. To the best of our knowledge, this is the first report of a trigger finger being caused due to this pathology. In this report, the authors review PF lesions on hands, advice careful evaluation of magnetic resonance imaging features, and recommend surgical management.

Plantaris muscle (lat. musculus plantaris) is a fusiform muscle of the superficial posterior leg compartment, characterized with a small muscle belly and very long and slender tendon. Many anatomical variations of plantaris muscle have been reported previously, including its inconstancy. Evolutional studies strongly suggest that plantaris muscle is a rudimentary muscle that plays minor role in gait biomechanics. However, plantaris muscle seems to have very important proprioceptive role since it has very high density of muscle spindles. Clinically, plantaris muscle is involved in differential diagnosis of posterior leg pain and several pathological entities such as: plantaris muscle rupture, non-insertional Achilles tendinopathy and popliteal artery compression syndrome. Different surgical specialties have recognized plantaris muscle tendon as a valuable graft. However, literature on plantaris muscle tendon biomechanical properties is rather scant and inconsistent with several limitations for proper data comparison and interpretation. Further comparative studies are needed to properly define biomechanical properties of plantaris muscle tendon grafts for various ligament and tendon reconstructive procedures.
