This case involved a 53 year old man who sustained a significant tear of his rotator cuff while playing baseball. He underwent surgical repair and was given a referral for physical therapy. The referral was to begin passive ROM 3 times per week for 2 weeks then initiate a supervised home program of active exercise for 2 weeks, and elastic resistance exercises for internal and external rotation every other day for a month. 2 weeks after surgery, he had his first PT visit in a sports medicine clinic that was managed by an athletic trainer (ATC).”
The most common knee injury in sports is damage to the anterior cruciate ligament (ACL) through tears or sprains. “They occur in high demand sports that involve planting and cutting, jumping with a poor landing, and stopping immediately or changing directions” (University of Colorado Hospital). The ACL is a ligament that runs diagonally in the middle of the knee and found at the front of the patellar bone. Its function involves controlling the back and forth motion of the knee, preventing the tibia from sliding out in front of the femur, and providing rational stability to the knee. Interestingly, women are more prone to ACL injuries than men. The occurrence is four to six times greater in female athletes.

Ligaments are tough, non-stretchable fibers that hold bones together. Damage to cruciate ligaments, which crisscross the knee to give it stability, is one of the most common sports injuries. The “tear” occurs from changing direction rapidly, slowing down from running, or landing from a jump improperly. The A.C.L tear is one injury that worries athletes in all sports at all levels because of its devastating effects. People ages 15-25 that participate in basketball and other sports that require pivoting are especially at risk.
Osteoarthritis is a degenerative joint condition that primarily affects the hands, spine and the ankles and hips. It is known to be associated with aging, and is concerned with the cartilage that protects the joints (the meeting place of two bones). Normal cartilage allows for bones to slide over each other uniformly, acting as a shock absorber to any damage. However cartilage in osteoarthritis, located at the ends of the bones erodes and deteriorates, causing friction and hence pain, swelling and restricted movement. Therefore in osteoarthritic both the composition and appearance of the cartilage alters, while the body attempts to repair this damaged cartilage is broken down faster than it can be built up. A defective repair process can cause bone overgrowth, bone spur/osteocytes to form which can be seen at the ends of the joints. In osteoarthritis the bones come in close contact with each other, and wear away leaving the bone exposed and unprotected.
Anterior knee pain plagues the athletic community, the most common being runner’s knee or patellofemoral pain syndrome (PFPS). One point or another in an athlete’s career they have experienced this kind of pain. When comparing between male and female athletes and who has the higher chance of knee pain, female athletes have a higher prevalence than male athletes (Dolak KL). There are several different mechanisms of patellofemoral pain a few being: pes planus,an increased Q angle, weak, tight or an imbalance in the quadriceps or hip muscles. Recently in my clinic site as the spring sports such as, baseball, soccer and track and field the athlete’s perform a lot of squatting, running, and kneeling which load the patellofemoral joint. We are now starting to see several and treat several athletes with patellofemoral knee pain. Each of them experiencing the pain from a different mechanism. As an athletic trainer we want to treat not only the symptoms, but the mechanism of injury to prevent further injuries down the road. If patellofemoral pain syndrome is not properly treated it can develop into chronic diseases such as chondromalacia or arthritis, maybe eventually leading to a total knee plan. (Lee SE) Treatment while the athletes are young and symptoms aren’t severe is key to preventing further injury.
The majority of ACL injuries suffered during athletic participation are of the noncontact variety. Three main noncontact mechanisms have been identified planting and cutting, straight-knee landing and one-step stop landing with the knee hyperextended. Pivoting and sudden deceleration are also common mechanisms of noncontact ACL injury. Basketball, soccer, and volleyball consistently produce some of the highest ACL injury rates across various age groups. Other activities with a high rate of injury are gymnastics, martial arts, and running. In most sports, injuries occur more often in games than in practice. Many injuries have occurred during the first 30 minutes of play. One-reason physicians are seeing more ACL injuries in female patients that more women play sports, and they play more intensely. But as they continued to do more studies, they are finding that women's higher rate of ACL is probably due ...
In order to develop this prosthesis they had to go through two main phases, the analysis of a jogger wearing a standard walking prosthesis and computer simulation of the flexing of the knee on this walking prosthesis. They had to measure rotation, weight bearing, moments, and t...
Orthopedic surgeons are responsible for mending and operating on the musculoskeletal system. “Orthopedics is a medical specialty that focuses on the diagnosis, care, and treatment of patients with disorders of the bones, joints, muscles, ligaments, tendons, nerves, and skin” (Career in Orthopaedics). Depending on the damage the patient has sustained determines how the orthopedic surgeon is able to correct the patient’s injury. In many cases there are multiple ways of correcting the patient’s injury such as; using medical, physical, and rehabilitative techniques to using complex surgical methods. “Typically, as much as 50 percent of the orthopedic surgeon’s practice is devoted to no surgical or medical management of injuries or disease and 50 percent to surgical management” (Career in Orthopaedics). The majority of surgeons, including orthopedic surgeons, prefer to choose the least invasive procedures such as; arthroscopy which is a technological advancement allowing orthopedic surgeons to use special cameras in order to diagnose and treat a joint with minimal cutting and trauma to...
The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
A study on the late effects of meniscectomy ten to thirty years after surgery revealed that only 10 percent of women who underwent the surgery had symptom-free knees [TAPPER et. al, 1969]. Less invasive methods such as arthroscopic surgeries have been introduced to preserve the joint capsule as much as possible and have provided satisfactory results. For instance, central quadriceps tendon-bone autograft performed on patients with ACL injuries produced successful results in a majority of patients 27 to 49 months post operatively [Lee et. al, 2004]. Therefore, the complicated interaction of tissues inside the knee plays a crucial role in the well-being of the organ. Thorough understanding of this complex interaction enables the healthcare professionals to design better treatment plans and also provide better injury prevention
Each patient receives a comprehensive examination using objective and subjective measures to assess pain, movement patterns, muscle performance, posture, endurance, flexibility, joint accessory motion, and a detailed medical history in order to identify the underlying cause of symptoms. Getting to the root cause of the issue allows us to more effectively treat the problem and devise a personalized treatment plan.
