In most cases, the patellar tendon tears at the point where it attaches to the knee cap. [1] Diagnosis is based on symptoms, examination, and medical imaging. [1] Small tears may be treated with rest and splinting, followed by physiotherapy. [1] [2] Larger tears typically require surgery within a couple of weeks. [1] [2] Outcomes are generally ...
Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .
Symptoms are pain and the inability to extend the knee against resistance. A gap can often be palpated at the tendon's normal location. A gap can often be palpated at the tendon's normal location. Diagnosis
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
Symptoms include pain, swelling, and bruising to the front of the knee. [1] A person may also be unable to walk. [1] Complications may include injury to the tibia, femur, or knee ligaments. [2] It typically results from a hard blow to the front of the knee or falling on the knee. [1] The patella can also be fractured indirectly.
The initial injury to the knee, whether resulting from macro- or repetitive microtrauma, leads to the same result: calcific ossification of the soft tissue structures surrounding the medial femoral condyle. [2] This sprain or tear in the medial collateral ligament leads to inflamation of the area.
High quality MRI images (1.5 T magnet or higher [22]) of the knee can be extremely useful to diagnose injuries to the posterolateral corner and other major structures of the knee. [23] While the standard coronal , sagittal and axial films are useful, thin slice (2 mm ) coronal oblique images should also be obtained when looking for PLC injuries.
The common signs and symptoms of a torn meniscus are knee pain, particularly along the joint line, and swelling. These are worse when the knee bears more weight (for example, when running). Another typical complaint is joint locking, when the affected person is unable to straighten the leg fully.
