Training and recovery

Can insufficient sleep increase sports injury risk and slow recovery?

Insufficient sleep can reduce reaction speed, attention, and movement control and can interfere with muscle repair, pain regulation, and recovery after training. Athletes should keep a regular schedule and allow enough sleep for their training load. Persistent insomnia, marked daytime sleepiness, or snoring with pauses in breathing warrants assessment.

Youth strength training

Can strength training stunt growth or damage growth plates in young athletes?

When supervised by a qualified adult, strength training with appropriate loads, sound technique, and gradual progression does not usually impair height development. The main risks come from unsupervised training, maximal-load attempts, poor technique, and equipment accidents. Maximum-lift testing should be avoided before skeletal maturity.

Knee osteoarthritis

Can someone with knee osteoarthritis continue running or doing squats?

Many people with knee osteoarthritis can remain active, and strength training can improve pain, stability, and daily function. Running and squat depth should be adjusted to pain, swelling, range of motion, and previous training experience. Reduce the load or use lower-impact exercise when symptoms remain meaningfully worse after activity.

Foot sports injury

What is turf toe after the big toe bends too far upward?

Turf toe is a sprain of the structures under the first metatarsophalangeal joint caused by excessive upward bending of the big toe. It is common in football, basketball, and dance and hurts during push-off, running, or rising onto the toes. Mild injuries may be protected with activity modification, taping, and a stiff-soled shoe; marked instability requires further assessment.

Muscle injury

Could inner-thigh pain after kicking or changing direction be an adductor strain?

Yes. An adductor strain often occurs during sprinting, kicking, or rapid changes of direction. Pain is usually felt in the inner thigh or groin and worsens with squeezing the legs or moving sideways. Rehabilitation should progressively restore adductor strength, trunk control, and change-of-direction ability while excluding hip or bone stress injury.

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.
