The patellar tendon elongates from the inferior pole of the patella‚ as an extension of the tendon of the quadriceps femoris muscle to the tibial tuberosity. The role of the patella tendon is to transfer the force of the quadriceps muscles‚ much like a rope around a pulley‚ as your knee straightens. (John Miller‚ 2015) Definition Excessive jumping or landing strains the patella tendon. At first the damage may only be minor and not cause any problem. However‚ if the tendon is repeatedly strained

joint contains four ligaments‚ one tendon‚ and some meniscus and cartilage. The lateral collateral ligament (LCL) runs from the femur to the fibula on the inner half of the knee. The medial collateral ligament (MCL) runs from the femur to the tibia on the outer half of the knee. The posterior cruciate ligament (PCL) crosses behind the ACL. The meniscus and cartilage in the knee provide shock absorbing for the knee and helps prevent arthritis. The patellar tendon connects the patella (kneecap) to the

It is important to recognize partial or full thickness tears of the cuff‚ degenerative changes related to age‚ effusion‚ and calcifications. When evaluating tendons it is important to look for a “break” in the hyperechoic tendon‚ if this is seen it usually represents an injury such as a tear. Rotator cuff tears are a common finding in the aging patient. If the humeral head and acromion have direct contact there is indication of a massive cuff tear. Intrasubstance lesions are the most common partial

ADVANTAGES AND DISADVANTAGES OF PRESTRESSED CONCRETE ADVANTAGES : Use of high strength concrete and freedom from cracks‚ in prestressed members‚ contribute to improved durability under aggressive environmental conditions. The use of high strength concrete and high tensile steel in prestressed concrete members results in lighter and slender members than could be possible by using reinforced concrete and Mild steel as reinforcement. In prestressed concrete‚ steel is no longer required for

invincible‚ and he was‚ until an arrow pierced his Achilles tendon. The Achilles tendon stretches down the lower leg to the heel and connects the calf muscle to the heel. You can have many different injuries to this tendon‚ and one of them is the rupturing of the tendon. It is usually a distinct diagnosis‚ whether the Achilles is rupture or not. There are both surgical and non-surgical treatment options to repair a ruptured Achilles tendon (2). Physical therapy can be very helpful to the healing process

takes origin from the extensor surfaces of the radius and ulna‚ as in other squirrels‚ and the tendon passes through the radial compartment of the wrist superficial to the tendons of the extensor carpi radialis brevis and longus muscles. The tendon of the abductor pollicis longus bifurcates with one part inserting on the metacarpal of the thumb and the other part inserting on the falciform bone‚ the tendon to the falciform bone is the larger of the two. Between the dorsal surface of the falciform bone

Figure skaters are at increased risk to ankle injuries‚ particularly injuries to the peroneal tendon. This is mainly due to the increase in boot stiffness since the elimination of figures and shift of training focus to freestyle‚ mainly‚ jumping. Today‚ boots must be stiffer than ever to accommodate impact from more triple and quadruple jumps (Porter et al. 2007). This in turn causes ankles to become weaker and injury rates to increase‚ especially due to poor training habits. According to estimations
