Joint locks in MMA place repeated stress on the elbow, shoulder, and knee through hyperextension, compression, and rotational forces. Over time, this may affect ligament stability, tendon integrity, and cartilage surfaces. While not all discomfort indicates injury, persistent symptoms may reflect underlying structural changes that can influence joint function, training capacity, and long-term movement patterns.

Clavicle fractures are common in athletes involved in contact and high-impact sports. This article explores when sling treatment may be appropriate, when surgery may be considered, and how fracture displacement, shoulder mechanics, rehabilitation, and sporting demands influence recovery. It also explains key factors affecting return-to-sport timelines and long-term shoulder function following a broken collarbone injury.

Persistent pain near the “sit bone” during running or prolonged sitting may be linked to proximal hamstring tendinopathy rather than simple muscle tightness. This article explores the symptoms, contributing biomechanical factors, and differences from sciatica, while outlining how tendon overload develops over time and what recovery and rehabilitation may involve for runners experiencing ongoing deep buttock pain.
