Sprains, strains, bruises, tendinopathy and bursitis are the most common soft-tissue injuries. They differ in what is damaged and in how they are best managed.
Soft-tissue injuries fall into two groups that behave quite differently. Acute injuries follow sudden trauma — a fall, a twist, a blow — and include sprains (ligament), strains (muscle and tendon) and contusions (bruising of muscle). Overuse injuries build gradually when an activity is repeated so often that the tissue never fully recovers between sessions; tendinopathy and bursitis are the common examples. Getting the category right matters, because early protection helps an acute injury while load management and progressive strengthening are what change an overuse problem.
Assessment focuses on the mechanism of injury, what structure is likely damaged, and whether anything more serious needs excluding — fracture, joint instability, a complete tendon rupture, or in the case of a deep contusion, compartment syndrome. Most soft-tissue injuries are diagnosed clinically and need no imaging. Investigations are ordered when they will change management, such as ruling out a fracture or characterising a suspected muscle tear or haematoma.
First-line care for an acute injury is relative rest, ice, compression and elevation in the first days, followed by graded exercise to restore movement and strength; bracing is used for moderate sprains and surgery reserved for severe ligament or tendon disruption. For overuse problems the mainstay is progressive loading under physiotherapy guidance rather than complete rest — repeated corticosteroid injection around a tendon is discouraged in current Australian guidance because medium-term outcomes are poorer. Where a tendon problem has not responded to a well-delivered loading program, adjuncts such as shockwave therapy may be considered, with the evidence discussed honestly case by case.
