Sports Medicine Q&A

Brief, easy-to-understand answers to common sports injury, treatment, and rehabilitation questions.

Wrist sports injury

Could pain on the little-finger side of the wrist be a TFCC injury?

Yes. The triangular fibrocartilage complex (TFCC) lies on the ulnar side of the wrist and can be injured by a fall onto the hand, racquet sport, lifting, or repeated wrist rotation. Common symptoms include ulnar-sided pain, pain with rotation or pushing up from a chair, clicking, and reduced grip strength. Tendon disorders and occult fractures can cause similar symptoms.

Acromioclavicular joint injury

Does an acromioclavicular joint injury or separation require surgery?

An acromioclavicular joint injury often follows a fall directly onto the shoulder. Mild-to-moderate injuries commonly recover with short-term sling use, pain control, and progressive rehabilitation. Surgery may be considered for marked clavicle displacement, high sporting demands, or persistent pain and weakness after non-operative care.

Shoulder injury

What is a shoulder SLAP tear, and what symptoms can it cause?

A SLAP tear affects the upper shoulder labrum near the attachment of the long head of the biceps tendon. It can follow throwing, repeated overhead activity, traction on the arm, or a fall onto the hand. Symptoms may include deep shoulder pain, clicking, catching, reduced throwing power, and early fatigue.

Sports medicine injection

Does PRP injection work for sports injuries, and who may benefit?

The effects of platelet-rich plasma (PRP) vary with the condition, duration of symptoms, and preparation method. Selected patients with chronic tendinopathy or mild-to-moderate joint degeneration may discuss PRP when structured rehabilitation has provided limited relief. Review the strength of evidence, cost, and realistic expectations before treatment.

Sports injury care

Which department should you visit for a sports injury: orthopaedics, sports medicine, or rehabilitation?

Sports medicine is a suitable first choice for acute sprains, muscle strains, joint swelling, or persistent exercise-related pain. Go to emergency care or orthopaedics for deformity, inability to bear weight, or a suspected fracture or dislocation. Rehabilitation medicine is helpful when the diagnosis is established and the main goal is to restore motion and strength.

Return to sport

What criteria should be met before returning to sport after an injury?

Return-to-sport decisions should assess pain and swelling, range of motion, strength, balance, endurance, psychological readiness, and the quality of sport-specific movement. Time is only one consideration. Athletes should complete graded training and monitor the response afterward; standardised functional tests can support decisions in higher-risk sports.

Foot sports injury

How can a Lisfranc injury be recognised after a midfoot sprain?

A Lisfranc injury affects the tarsometatarsal joints and commonly causes midfoot swelling, pain with weight bearing, and bruising on the sole. A ligament or bone injury may still be present when walking is possible. Prompt assessment with weight-bearing X-rays and, when needed, CT or MRI is important.

Read answer
Heel pain

Could heel pain with the first steps in the morning be plantar fasciitis?

Yes. Plantar fascia pain commonly affects the inner heel and is most noticeable with the first steps after waking or sitting, sometimes easing temporarily with movement. Treatment often includes modifying running and jumping load, calf and plantar-fascia mobility work, foot strengthening, and suitable footwear. Persistent pain requires assessment for a stress fracture or nerve entrapment.

Muscle injury rehabilitation

When can running and competition resume after a hamstring strain?

Use functional criteria rather than a fixed number of days. Before running, walking and basic movement should be nearly pain-free and strength should be adequate. Before competition, the athlete should complete high-speed running, acceleration, deceleration, and sport-specific drills without a meaningful increase in symptoms afterward.

Read answer
Throwing injury

Could pain on the inside of the elbow during throwing be an ulnar collateral ligament injury?

Repeated throwing in baseball, javelin, and similar sports places high stress on the elbow ulnar collateral ligament. Symptoms may include medial elbow pain, reduced throwing speed, or a sense of instability. Assessment should also consider throwing volume, technique, the flexor tendons, and the ulnar nerve. Treatment may involve load modification, rehabilitation, or surgery for a severe tear.

Sports-related back pain

Could recurrent low-back pain in an adolescent athlete be spondylolysis?

Spondylolysis is seen in sports that repeatedly extend and rotate the lower back, including gymnastics, diving, and football. Pain often worsens with back extension or after training. Early cases may improve with training modification, core rehabilitation, and a staged return to sport; persistent pain warrants imaging assessment.

Sports hydration

How much should you drink during exercise, and how can dehydration and hyponatraemia be avoided?

Fluid intake should reflect sweat loss, temperature, exercise duration, and individual tolerance. After long sessions, body-weight change can help estimate replacement needs. Avoid forcing large amounts of fluid over a short period, and consider electrolytes during prolonged exercise with heavy sweating. Headache, nausea, confusion, or severe weakness requires immediate assessment.

Read answer
Sports nutrition

Can sports supplements improve performance or speed recovery from injury?

Supplements such as protein or creatine may help selected people when used appropriately, but they cannot replace a balanced diet, sound training, and sleep. Products may contain inaccurate doses, contaminants, or banned substances. Competitive athletes should choose independently tested products and consult a doctor or sports dietitian first.

Read answer
Training and recovery

Do persistent fatigue and declining performance indicate overtraining syndrome?

Persistent fatigue, reduced performance, sleep or mood changes, an unusual resting heart rate, and recurrent illness can occur when training load and recovery are out of balance. Anaemia, infection, thyroid disease, and low energy availability should also be excluded. Management centres on reducing load, improving sleep and nutrition, and returning gradually.

Sports nutrition

What is relative energy deficiency in sport (RED-S)?

RED-S develops when long-term energy intake does not adequately support training and essential body functions. It can affect menstrual function, bone health, hormones, immunity, mood, and performance. Recurrent stress fractures, unusual weight change, persistent fatigue, or menstrual disturbance warrant coordinated assessment by sports medicine, nutrition, and other relevant specialists.

Read answer
Sports emergency

How can exertional heat stroke be recognised during exercise?

A very high body temperature with confusion, unusual behaviour, poor coordination, seizures, or loss of consciousness should raise strong concern for exertional heat stroke. Start emergency care and rapid whole-body cooling immediately and call emergency services. Continue cooling while transport is arranged.

Read answer
Sports concussion

Can an athlete return to play on the same day after a concussion?

No. Anyone with a suspected concussion should be removed from sport immediately, assessed by a qualified professional, and guided through a staged return to learning, daily activity, and sport. Worsening headache, repeated vomiting, altered consciousness, seizures, or limb weakness requires emergency care.
