The PRP has been used extensively by our clinic’s doctors for the treatment of various illnesses such as the knee pain, shoulder pain and smaller joint pain, lower back pain, and for the aesthetic indications.
The muscle injury happens very frequently. The most common injury includes the “strains” or “pulls” and tear. The muscle injury affects a large population of athletes every day and every year. The muscle is attached to the bone at the both ends through the tendons. Therefore a great amount of force is exerted through the tendon during a burst of forceful activity such as the push-up of the first step of a sprint. During the bursting activities such as sprinting and smashing moment of the tennis game which require sudden change of direction of movement, the force applied across the musculo-tendon unit can be very explosive and immense.
The commonest injury occur during the non-aligned or also called eccentric loading of the muscle. This is to say, the muscle is contracting while it is elongating. The muscle that span across two joints are most susceptible to injury. Such muscle includes for example the hamstrings, the calf, and the quadriceps. The hip adductor muscle, which is the internal rotators is also quite commonly affected.
All the muscle has a outer covering which allow it to move smoothly over one another. The muscle is made up of bundles of muscle fibers called fascicles. The fascicles is made up of myofibrils. The myofibrils is composed of microscopic sarcomeres. The sarcomeres are responsible for muscle contraction. Inside the sarcomeres are protein myosin and actin. The myosin pull against the thinner actin. As the myosin pulls the sarcomere shorten, called contraction. Conversely, when the sarcomeres lengthen back to the initial position, the muscle lengthen.
The muscle injury starts to happen when the force it produces is so great. It is so great that the tissue start to tear apart. The location of this injury may occur:
The 3-stage healing process is:
|Grade 2||Grade 3|
|Mild damage to individual fibers, < 5% fibers||More muscle fibers damaged
Muscle not ruptured
|Minimal loss of strength and motion||Significant loss of strength and motion||Loss of motion and strength
Take surgery to repair, reattaches
|Take 2-3 weeks to improve||Take 2-3 months before complete return to athletics||3 months|
|X ray or CT scan can see if bone fragment detaches||MRI can see deficit, ruptured structures, haematoma|
|Rx: RICE Rest, ice, compression, elevation) , NSAID (eg ibuprofen), progressive functional physical therapy||RICE, NSAID, progressive functional physical therapy||Surgery to reattaches|
|PRP may stimulate muscle healing, regeneration, less scar formation||PRP may stimulate muscle healing, regeneration, less scar formation||PRP may stimulate muscle healing, regeneration, less scar formation
Losartan (anti-hypertensive) is thought to reduce scaring.
