PATELLAR / QUADRICEPS TENDINITIS

WHAT IS PATELLAR / QUADRICEPS TENDINITIS?

Patellar tendinitis is a common overuse injury. It occurs when repeated stress is placed on the patellar tendon. The stress results in tiny tears in the tendon, which the body attempts to repair. However when the tears in the tendon increase faster than what the body can recover, it […]

Periarticular Ligamentous Tissue: A Biochemical and Physiologic Assessment-Structure

Structure

The histology of periarticular tendons and ligaments is a much-neglected area of investigation. Although many histology texts combine these two tissues as “dense, regular connective tissue”, certain ligaments and tendons are sufficiently characteristic to be distinguishable from each other based upon their histological appearance .

The variables considered are collagen bundle width, cell morphology […]

Palpation of soft tissues at the medial side

Medial collateral ligament

The medial collateral Hgament is a broad, flat and almost triangular band, with a large insertion on the posterosuperior aspect of the medial femoral epicondyle, dose to the insertion of the adductor magnus tendon. Its fibres run obliquely, anteriorly and inferiorly, to insert at the medial aspect of the tibia, just behind […]

Palpation of the extensor mechanism

This is performed on an extended knee.First the muscular structures are ascertained. Ask the patient to extend the slightly bent knee and resist the movement.This movement usually outlines the vastus medialis, vastus lateralis, rectus femoris and the patellar ligament. Then the patellar border with its tendinous insertions are palpated. With the hip in flexion and […]

Bursitis

The knee is surrounded by several bursae.

Prepatellar bursitis The prepatellar bursa is located anterior and distal to the patella. Its location makes it vulnerable to traumatic bursitis. Team handball players, American football players, soccer players, wrestlers, and gymnasts are at increased risk. One study reported that 9.5% of wrestlers had prepatellar bursitis over a […]

Traction tendinitis

Sinding-Larsen-Johansson disease

Sinding-Larsen-Johansson disease is a traction tendinitis of the distal pole of the patella, caused by microtrauma. It is seen in growing individuals; who have pain at the inferior pole of the patella in association with running and jumping. Typical clinical signs are point tenderness at the inferior pole of the patella, swelling, limitation […]

Knee extension mechanism injuries

The knee extension mechanism includes the quadriceps muscle-tendon, the patellar bone, the patellar tendon, and its insertion into the tibia. Injuries can occur in all these structures.

Quadriceps tendon injuries The distal quadriceps tendon attaches to the patella and its adjacent soft tissue structures (the retinaculum). It is important for the extensor mechanism. This tendon […]

Knee

The knee is the most frequently injured joint in athletics.Most injuries are due to the extreme stresses of twisting and turning activities such as those found in skiing, soccer, and American football. Medial collateral ligament and meniscal injuries are in the majority, but anterior cruciate ligament ruptures are also common and are responsible for a […]

Partial Tendon Rupture

In partial tendon rupture (first- and second-degree strains), the tendon is only partly torn. Depending on the extent of the injury, the affected athlete may not always be aware that a rupture has occurred, but believes the tendon to be overused and inflamed. Partial ruptures can be divided into acute and chronic injuries.

Symptoms and […]

Patellar Tendinosis

SYMPTOMS

Gradual onset of diffuse exercise induced pain or ache around the proximal part of the patellar tendon. It is common in middle-aged runners and recreational athletes in racket sports.

AETIOLOGY

Tendinosis is defined from histopathological findings as a free tendon condition with altered collagen structure, thickening of the tendon, re-vascularisation and increased […]
