Raju Vaishya, Ahmad Tariq Azizi, Amit Kumar Agarwal, Vipul Vijay
Osgood-Schlatter disease (OSD) is a condition in which the patellar tendon insertion on the tibial tuberosity becomes inflamed. It is a well-known condition in late childhood characterized by pain and a bony prominence over the tibial tuberosity. The pain is usually exacerbated by physical activities like running, jumping, and climbing stairs. In the acute stage, the margins of the patellar tendon become blurred in radiographs due to the soft tissue swelling. After three to four months, bone fragmentation at the tibial tuberosity is viewed...

Tear of the quadriceps tendon after revision or primary total knee arthroplasty is a rare complication, but when it occurs, this injury has serious functional consequences. In complete tears, the outcome of direct repair is unpredictable, and several authors recommend that the suture should be reinforced. Several techniques have been described, including the use of autografts, allografts, and synthetic mesh. The goal of this study was to assess the outcomes of a reconstruction technique augmented with synthetic mesh...

BACKGROUND: Anterior cruciate ligament (ACL) tears are frequently treated with surgical reconstruction with grafts, frequently patella tendon or hamstrings. Interference screws are often used to secure the graft in bone tunnels in the femur and tibia. This review examines whether bioabsorbable interference screws give better results than metal interference screws when used for graft fixation in ACL reconstruction. OBJECTIVES: To assess the effects (benefits and harms) of bioabsorbable versus metallic interference screws for graft fixation in ACL reconstruction...

Patellar and quadriceps tendon ruptures are relatively common injuries. Rupture of the knee extensor mechanism may occur because of a forceful eccentric contraction of the quadriceps against a resisted flexed knee, though atraumatic cases have also been described. Patients at higher than normal risk for knee extensor mechanism rupture include those with systemic co-morbidities, fluoroquinolone use, and chronic tendinopathy. Early operative treatment and mobilization of acute extensor mechanism ruptures has proven effective, and numerous techniques have been described...

BACKGROUND: Low-intensity pulsed ultrasound stimulation (LIPUS) has been proven to be a beneficial biophysical therapy for tendon-bone (T-B) healing. However, the optimal time to initiate LIPUS treatment has not been determined yet. LIPUS initiated at different stages of the inflammatory phase may profoundly affect T-B healing. PURPOSE: An established rabbit model was used to preliminarily investigate the effect of LIPUS initiation timing on T-B healing. STUDY DESIGN: Controlled laboratory study...

UNLABELLED: : Tendon injuries are common and present a clinical challenge, as they often respond poorly to treatment and result in long-term functional impairment. Inferior tendon healing responses are mainly attributed to insufficient or failed tenogenesis. The main objective of this study was to establish an efficient approach to induce tenogenesis of bone marrow-derived mesenchymal stem cells (BMSCs), which are the most common seed cells in tendon tissue engineering. First, representative reported tenogenic growth factors were used as media supplementation to induce BMSC differentiation, and the expression of teno-lineage transcription factors and matrix proteins was compared...

Quadriceps tendon rupture is an uncommon injury. This disabling condition is the result of direct or indirect trauma. It requires surgical repair to avoid poor outcomes in cases of neglected or chronic rupture. In most acute cases, simple tendon suture or reinsertion is suitable for an extensor mechanism reconstruction of the knee joint. However, chronic lesions often require a tendon graft or flap reconstruction. We report a case of a 15-year-old male who was diagnosed with a chronic quadriceps rupture with a patellar superior pole fracture...

Platelet-enriched plasma (PRP) contains high concentration of platelets and abundant growth factors, which is made by centrifuging of blood and separating of blood elements. PRP promotes tendon repair by releasing various cytokines to enhance cell proliferation, tenogenic differentiation, formation and secretion of matrix; meantime, it can reduce pain by inhibiting the expression of pain-associated molecules. A number of clinical studies demonstrated that PRP was effective in treatment of tendinopathy, including patellar tendinopathy, lateral epicondylitis and plantar fasciopathy...

Patellar tendon rupture is an uncommon clinical presentation, which generally affects the under 40s who are active in sport. Bilateral rupture of both tendons is much rarer. It occurs most frequently in patients with predisposing factors such as corticosteroid use or systemic diseases. The authors present the case of a 56-year-old male on long-term statin therapy who sustained this injury following a fall on ice. He had no known risk factors for tendon rupture. Surgical treatment involved tendon repair using Krakow suture via bony tunnels in the patella...

BACKGROUND: The "initial graft tension" applied at the time of graft fixation during anterior cruciate ligament (ACL) reconstruction surgery modulates joint contact mechanics, which in turn may promote posttraumatic osteoarthritis (OA). PURPOSE/HYPOTHESES: The study objectives were to compare clinical, functional, patient-reported, and OA imaging outcomes between 2 different initial laxity-based graft tension cohorts and a matched uninjured control group as well as to evaluate the effects of laxity-based graft tension on OA development at 84-month follow-up...

BACKGROUND: Tendon-to-bone healing is a complex and slow process, and the rate of poor healing remains high. In recent years, several new strategies have been developed that enhance tendon-to-bone healing by increasing the bioactivity. Fibrin clots have been widely used to improve tissue healing and tissue engineering, HYPOTHESIS: Modified fibrin clots can improve the bioactivity of the tendon-bone interface and histological appearance. STUDY DESIGN: Controlled laboratory study...
