Review
Anterior cruciate ligament (ACL) injuries are the most common ligament injury of the knee, accounting for between 100,000 and 200,000 injuries among athletes per year. ACL injuries occur via contact and non-contact mechanisms, with the former being more common in males and the later being more common in females. These injuries typically require surgical repair and have relatively high re-rupture rates, resulting in a significant psychological burden for these individuals and long rehabilitation times. Numerous studies have attempted to determine risk factors for ACL rupture, including hormonal, biomechanical, and sport- and gender-specific factors. However, the incidence of ACL injuries continues to rise. Therefore, we performed a systematic review analyzing both ACL injury video analysis studies and studies on athletes who were pre-screened with eventual ACL injury. We investigated biomechanical mechanisms contributing to ACL injury and considered male and female differences. Factors such as hip angle and strength, knee movement, trunk stability, and ankle motion were considered to give a comprehensive, joint by joint analysis of injury risk and possible roles of prevention. Our review demonstrated that poor core stability, landing with heel strike, weak hip abduction strength, and increased knee valgus may contribute to increased ACL injury risk in young athletes.

Although the role of shoe constructions on running injury and performance has been widely investigated, systematic reviews on the shoe construction effects on running biomechanics were rarely reported. Therefore, this review focuses on the relevant research studies examining the biomechanical effect of running shoe constructions on reducing running-related injury and optimising performance. Searches of five databases and Footwear Science from January 1994 to September 2018 for related biomechanical studies which investigated running footwear constructions yielded a total of 1260 articles. After duplications were removed and exclusion criteria applied to the titles, abstracts and full text, 63 studies remained and categorised into following constructions: (a) shoe lace, (b) midsole, (c) heel flare, (d) heel-toe drop, (e) minimalist shoes, (f) Masai Barefoot Technologies, (g) heel cup, (h) upper, and (i) bending stiffness. Some running shoe constructions positively affect athletic performance-related and injury-related variables: 1) increasing the stiffness of running shoes at the optimal range can benefit performance-related variables; 2) softer midsoles can reduce impact forces and loading rates; 3) thicker midsoles can provide better cushioning effects and attenuate shock during impacts but may also decrease plantar sensations of a foot; 4) minimalist shoes can improve running economy and increase the cross-sectional area and stiffness of Achilles tendon but it would increase the metatarsophalangeal and ankle joint loading compared to the conventional shoes. While shoe constructions can effectively influence running biomechanics, research on some constructions including shoe lace, heel flare, heel-toe drop, Masai Barefoot Technologies, heel cup, and upper requires further investigation before a viable scientific guideline can be made. Future research is also needed to develop standard testing protocols to determine the optimal stiffness, thickness, and heel-toe drop of running shoes to optimise performance-related variables and prevent running-related injuries.

Review
Ankle osteoarthritis constitutes a large burden to society and is a leading cause of chronic disability in the United States. Most commonly, it is post-traumatic, occurs in younger individuals, and is associated with obesity. This entity presents similarly to osteoarthritis of the other joints, with the typical nonspecific symptoms of stiffness, swelling, and pain. Radiographic investigation includes four weight-bearing standard views: antero-posterior and lateral foot, mortise view of the ankle, and a specialized view of the hindfoot. In this review, we covered epidemiology, anatomy and biomechanics, etiology, pathology, differential diagnoses, symptoms, physical examination, appropriate radiological investigation, as well as current treatment options and algorithms. Non-operative treatment options include weight loss, physical therapy, bracing, orthoses, pharmacologic treatments, corticosteroid injections, viscosupplementation, and biologic modalities. Viscosupplementation with hyaluronic acid has the most evidence-based support and has been shown to be safe and efficacious. For patients who have moderate to severe disease, surgery may be indicated. However, current surgical options are either associated with high rates of complications or restrict ankle range of motion (ROM). Early stages of the ankle osteoarthritis should be treated with the above-mentioned non-surgical methods, and once the disease progresses, surgical options can be utilized.

Review
The elbow is a congruent joint with a high degree of inherent stability, provided by osseous and soft-tissue constraints; however, when substantial lesions of these stabilising structures happen, instability of the elbow occurs. Significant improvements in surgical elbow instability diagnosis and treatment have been recently introduced both for acute and chronic cases. Specific stress tests, recently introduced in the clinical practice, and different imaging techniques, both static and dynamic, allow assessment of the elbow stabilisers and detection of the instability direction and mechanism even in subtle forms. Many surgical techniques have been standardised and surgical instruments and devices, specifically dedicated to elbow instability treatment, have been developed. Specific rehabilitation protocols have been designed to protect the healing of the elbow stabilisers while minimising elbow stiffness. However, despite the progress, surgical treatments can be challenging even for expert surgeons and the rate of persistent instability, post-traumatic arthritis, stiffness and pain can be still high especially in most demanding cases. The biology of the soft-tissue healing remains one of the most important aspects for future investigation. If future research will help to understand, correct or modulate the biological response of soft-tissue healing, our confidence in elbow instability management and the reproducibility of our treatment will tremendously improve. In this paper, the state of the art of the current knowledge of elbow instability is presented, specifically focusing on modern surgical techniques used to solve instability, with repair or reconstruction of the damaged elbow stabilisers.

Review
BACKGROUND
Adhesive capsulitis of the shoulder (AC) is characterized by fibrosis and contracture of the glenohumeral joint capsule, resulting in progressive stiffness, pain, and restriction of motion of the shoulder. The prevalence of AC is estimated to be 2-5% of the general population. Patients with AC typically have an insidious onset of pain and can progress to severe limitation of the shoulder leading to significant disability and decreased quality of life.
OBJECTIVES
The objective of this manuscript is to provide a comprehensive review of AC with a focus on clinical presentation, natural history, pathophysiology, and various treatment modalities.
STUDY DESIGN
A review article.
SETTING
A review of literature.
METHODS
A search was made on the Pubmed database using the keywords of adhesive capsulitis, frozen shoulder, shoulder capsulitis, arthrofibrosis, shoulder pain, shoulder stiffness.
RESULTS
Our search identified numerous studies in order to provide a comprehensive review of the current understanding of the treatment and management of AC.
LIMITATIONS
There remains limited evidence in literature about the understanding of AC and optimal treatment.
CONCLUSION
AC is an important cause of chronic pain and disability. There is currently no consensus on treatment. Initial treatment modalities revolve around conservative measures as well as aggressive physical therapy. Further treatment options include intraarticular injections, hydro-dilation, nerve blocks, and for more refractory cases, surgical interventions such as arthroscopic capsulotomy.

A 10-year-old North Indian boy presented with swelling of multiple joints in his hands for the past 3 years. This swelling involved the small joints of his hands and some restriction of joint movement, without any associated tenderness or morning stiffness. No other joints were symptomatically involved. Prior to visiting our hospital, he had received disease-modifying antirheumatoid drugs for suspected juvenile idiopathic arthritis, without any clinical benefit. On examination, the metacarpophalangeal and interphalangeal joints were nontender but had swelling and flexion deformities. He also had a short stature (below the third centile) for his age. Inflammatory markers, including erythrocyte sedimentation rate (7 mm per hour; normal range, 0-22 mm per hour) and C-reactive protein level (1.5 mg/L; normal level, <10 mg/L), were normal, and the rheumatoid factor test result was negative. A skeletal survey of the patient was performed and is shown in Figures 1-6.

Review
Joint bleeds cause major morbidity in haemophilia patients. The synovial tissue is responsible for removal of blood remnants from the joint cavity. But blood components, especially iron, lead to a series of changes in the synovial tissue: inflammation, proliferation and neovascularization. These changes make the synovium vulnerable to subsequent bleeding and as such a vicious cycle of bleeding-synovitis-bleeding may develop leading to chronic synovitis. The initial step in the treatment is adequate clotting factor supplementation and immediate physiotherapeutic involvement. If these measures fail, synovectomy may be indicated. Non-surgical options are chemical and radioactive synovectomy. This is a relatively non-invasive procedure to do synovectomy, leading to a reduction in pain and joint bleeds. Radioactive synovectomy seems more effective than chemical synovectomy in larger joints. Surgical options are open and arthroscopic synovectomy. Open synovectomy has been found to decrease the incidence of breakthrough bleeds but at the cost of loss of joint motion. Use of arthroscopic synovectomy has been advocated to reduce bleeding episodes with less morbidity to extra-articular tissue and preservation of joint motion. Use of a continuous passive motion (CPM) machine and early mobilization can decrease the postoperative stiffness and promote early recovery. This review addresses the current understanding of synovitis and its treatment options with specific emphasis on chemical and radioactive synovectomy and surgical options.

Review
Infections in the joints of the hand and wrist carry the risk of significant morbidity. Common presenting symptoms include joint redness, swelling, and pseudoparalysis that occurs several days following a penetrating trauma. Diagnostic workup should be expedited, including a laboratory evaluation and arthrocentesis. Imaging, including radiographs, ultrasound, computed tomography, and/or MRI, are helpful tools in diagnosis. Once infection is identified, prompt surgical debridement and antibiotics are required. Once the infection has been managed, hand therapy is initiated to decrease the risk of stiffness. Stiffness is the most common complication following infection; additional reported complications include arthritis, ankylosis, and amputation."

Review
Shoulder stiffness is a condition of restricted glenohumeral range of motion, which can arise spontaneously or as consequence of a known cause, including surgical procedures on the shoulder. Several approaches to shoulder stiffness have been proposed and high-level evidence is available to analyze and discuss their results. The aim of this review was to summarize the current concepts on conservative and operative treatment of shoulder stiffness and discuss the results of the available studies with a high level of evidence, which should be considered to guide clinical practice. Treatment of shoulder stiffness should be tailored to the patient's clinical situation and the stage of its shoulder pathology and should aim at pain reduction, restoration of range of motion, functional regain and shortening of symptoms duration. When possible, known risk factors for primary shoulder stiffness and causes of secondary shoulder stiffness should be addressed to avoid relapse. Conservative therapy is the mainstay of treatment for shoulder stiffness and should include a multimodal and activity-oriented program. Intra-articular injection of a low dose of corticosteroid is safe and effective, provides immediate benefits, and is recommended in combination to an appropriate rehabilitation protocol. In conservative refractory cases, arthrolysis and capsular release can be performed with an arthroscopic approach.

Review
Degenerative disorders of the wrist may affect isolated joints and inhibit normal functions of the wrist secondary to pain and stiffness. These processes that affect only the radiocarpal joint may be secondary to posttraumatic osteoarthritis, primary osteoarthritis, or rheumatoid arthritis. Radiocarpal wrist arthrodesis may help preserve some of the native wrist kinematics while alleviating pain and improving the range of motion. However, the surgeon must ensure that the patient's pathologic process primarily affects the radiocarpal articulations while relatively sparing the midcarpal articulations. Depending on the location of the pathology, isolated radiolunate or radioscapholunate arthrodesis have been described to preserve some motion in the midcarpal joint. To maximize motion in the midcarpal joint after radiocarpal arthrodesis, techniques for distal scaphoid and triquetrum excision have been described. We report patient outcomes for various techniques and describe our preferred technique for radioscapholunate arthrodesis using distal scaphoid excision.
