Hope this helps. Of course, this is general; nobody knows what exact injury Cam has.
It's important to differentiate between a muscle tear(strain)and a central tendon tear, which has implications for hamstrings, quads and calves for starters.
- Injuries involving the quadriceps or hamstring intramuscular tendon have prolonged rehabilitation and return to play times—they must be treated differently to ‘muscle strains’.
- Differentiation of these intramuscular tendon injuries seems particularly important in injuries to the biceps femoris and rectus femoris muscles.
- If injury to these tendons is suspected, MRI is indicated for accurate diagnosis
- There may be a role for surgical repair of the tendon in injuries with significant damage of the intramuscular tendon
- Improved recognition of injury of the intramuscular tendon may allow more accurate prediction of time to return to sport and thus, reduce risk of recurrence.
- The role of surgical repair versus conservative management in some of these injuries is not clear. The options need to be weighed carefully and discussed appropriately (shared decision-making) until more data provide a basis for clear recommendations.
Classification of Quadriceps Strains
Below provided is an outline of a clinical grading system for muscle strains. Factoring in pain, loss of strength, and physical exam findings in a grading system helps provide guidance for treatment, rehabilitation, and eventual return to play.
Muscle injuries also be broadly classified as either acute or chronic injuries.
- Grade I (mild) strains affect only a limited number of fibers in the muscle. There is no decrease in strength and there is a fully active and passive range of motion. Pain and tenderness are often delayed to the next day.
- Grade II (moderate) strains have nearly half of muscle fibers torn. Acute and significant pain is accompanied by swelling and a minor decrease in muscle strength.
- Grade III (severe) strains represent the complete rupture of the muscle. This means either the tendon is separated from the muscle belly or the muscle belly is actually torn in 2 parts. Severe swelling and pain and a complete loss of function are characteristic of this type of strain
- Acute injuries: are usually the result of a single traumatic event and cause a macro-trauma to the muscle. There is an obvious link between the cause and noticeable symptoms.They mostly occur in contact sports such as rugby, soccer and basketball because of their dynamic and high collision nature.
- Overusechronic or exercise-induced injuries)are subtler and usually occur over a longer period of time.They result from repetitive micro-trauma to the muscle. Diagnosing is more challenging since there is a less obvious link between the cause of the injury and the symptoms.
Grades of quadriceps strain
- Grade 1 symptoms: Symptoms of a grade 1 quadriceps strain are not always serious enough to stop training at the time of injury. A twinge may be felt in the thigh and a general feeling of tightness.The athlete may feel mild discomfort on walking and running might be difficult.There is unlikely to be swelling. A lump or area of spasm at the site of injury may be felt.
- Grade 2 symptoms: The athlete may feel a sudden sharp pain when running, jumping or kicking and be unable to play on.Pain will make walking difficult and swelling or mild bruising may be noticed.The pain would be felt when pressing in on the suspected location of the quad muscle tear.Straightening the knee against resistance is likely to cause pain and the injured athlete will be unable to fully bend the knee.
- Grade 3 symptoms: Symptoms consist of a severe,sudden pain in the front of the thigh.The patient will be unable to walk without the aid of crutches.Bad swelling will appear immediately and significant bruising within 24 hours.A static muscle contraction will be painful and is likely to produce a bulge in the muscle.The player can expect to be out of competition for 6 to 12 weeks.
Thanks Vdubs.
A concise explanation that we can all understand.
Thanks for taking the time mate.
