Pes anserinus ("goose foot") refers to the conjoined tendons of three muscles of the thigh. It inserts onto the anteromedial (front and inside) surface of the proximal tibia. The muscles are the sartorius, gracilis and semitendinosus sometimes referred to as the guy ropes. The name "goose foot" arises from the three-pronged manner in which the conjoined tendon inserts onto the tibia. Structure
The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. It inserts onto the proximal anteromedial surface of the tibia.The pes anserinus is around 5 cm below the medial tibial joint line. It lies superficial to the tibial insertion of the medial collateral ligament of the knee. Clinical significance
Pes anserine bursitis is a cause of chronic knee pain and weakness. It occurs when the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This condition usually occurs in athletes from overuse. This pathology is characterized by pain, swelling, and / or tenderness.The semitendinosus tendon can be used in certain techniques for reconstruction of the  anterior cruciate ligament. History
The name "goose foot" arises from the three-pronged manner in which the conjoined tendon inserts onto the tibia. Additional Images

By the age of 60, this number goes up to 70%. Construction workers also have an elevated risk. A screening program focused on construction workers employed at US Department of Energy facilities found 58% with significant abnormal hearing loss due to noise exposures at work. Occupational hearing loss is present in up to 33% of workers overall. Occupational exposure to noise causes 16% of adult disabling hearing loss worldwide.The following is a list of occupations that are most susceptible to hearing loss:
Agriculture
Mining
Police
Construction
Manufacturing
Utilities
Transportation
Military
Musicians
Orchestra conductors

Among musicians
Musicians, from classical orchestras to rock groups, are exposed to high decibel ranges. Some rock musicians experience noise-induced hearing loss from their music, and some studies have found that "symphonic musicians suffer from hearing impairment and that the impairment might be ascribed to symphonic music. "In terms of the population of musicians, usually the rates of hearing disorders is lower than other occupational groups. However, many exposure scenarios can be considered a risk of hearing disorders, and many individuals are negatively impacted by tinnitus and other hearing problems. While some population studies have shown that the risk for hearing loss increases as music exposure increases, other studies found little to no correlation between the two.
