Relative Energy Deficiency in Sport

Can normal-weight or male athletes develop REDs?

Yes. Any sex or body size can be affected, and stable weight does not exclude inadequate energy availability. Recurrent bone stress injuries, persistent fatigue, menstrual changes or low libido warrant assessment, improved fueling and training adjustment, while excluding other causes.

Hallux rigidus

Can I exercise after first MTP fusion for hallux rigidus?

Many people resume walking and selected sports, but the joint permanently loses motion. Activities needing substantial toe extension may be limited. Confirm fusion healing before progressing gait, strength and sport loading; discuss footwear and sporting expectations before surgery.

Accessory navicular syndrome

Should a painless accessory navicular be removed preventively?

Usually not. This anatomical variant often remains asymptomatic. Medial arch tenderness, shoe irritation or tendon symptoms merit assessment and conservative care. Surgery is considered for persistent symptoms despite appropriate treatment, not an X-ray finding alone.

Osteochondral lesion of the talus

Can talar lesion area alone determine microfracture treatment?

No. Depth, cysts, surface integrity, fragment stability and previous treatment matter. Selected small lesions may suit marrow stimulation; deeper or larger defects may need other reconstruction. Instability and alignment also matter, and repair tissue is not equivalent to native hyaline cartilage.

Peroneal tendon instability

Can static MRI miss painful peroneal tendon snapping?

Yes. Intermittent subluxation may occur only during movement. Dynamic ultrasound can assess tendon motion during a supervised maneuver. Persistent painful snapping or instability warrants evaluation; painless noise alone may not need treatment.

Thumb UCL injury

What is a Stener lesion in skier's thumb?

The torn thumb UCL displaces superficial to the adductor aponeurosis, which can block normal healing. Hand examination and ultrasound or MRI help confirm it; repair is commonly discussed. Protect the thumb and avoid repeated self-stress tests.

SLAP lesion

Does a SLAP tear on MRI require labral repair?

No. Age-related changes require correlation with symptoms and examination. Rehabilitation usually comes first. A randomized trial in selected isolated type II tears found no clear benefit of repair or tenodesis over sham surgery; its findings do not settle treatment for every young throwing athlete.

TFCC injury

Why are some TFCC tears debrided and others repaired?

Central tears have limited blood supply and selected symptomatic tears may be debrided after unsuccessful conservative care. Peripheral tears, particularly with instability, may suit repair. Tissue quality, ulnar length and associated injuries also matter.

Iliotibial band syndrome

Is foam rolling alone enough for iliotibial band syndrome?

Usually not. Adjust running volume and painful hills, and assess hip strength and movement before progressively rebuilding running. Rolling may ease discomfort temporarily but cannot replace load management; avoid aggressive pressure on painful areas.
