Joint loose bodies

Do loose bodies from synovial chondromatosis need arthroscopic treatment?

If loose bodies cause recurrent pain, swelling, catching, or restricted motion, surgery is often needed to remove them, and some patients also need treatment of abnormal synovium. Arthroscopic or open surgery depends on the number, size, and location of loose bodies and the synovial condition. Follow-up is needed for recurrence and osteoarthritis progression.

Clavicle fracture

Does every clavicle fracture need plate fixation?

Many clavicle fractures recover with a sling, pain control, and gradual activity. Surgery can be assessed for marked displacement, comminution, threatened skin, neurovascular risk, or special sport demands. Return to sport requires fracture healing and recovery of shoulder function.

Hand ligament injury

Could thumb-base instability after skiing or ball sports be skier’s thumb?

Yes. Skier’s thumb usually refers to injury of the ulnar collateral ligament of the thumb metacarpophalangeal joint, often after a fall onto the hand, ball-sport contact, or forced opening of the thumb. Mild injury may use splinting; complete tear, obvious instability, or Stener lesion usually requires hand-surgery assessment.

Stress fracture

Which stress fractures are high risk and need more active management?

Stress fractures of the femoral neck, navicular, proximal fifth metatarsal, and talus are higher risk because they may progress to complete fracture or non-union. MRI is often used when pain persists despite normal X-rays. High-risk sites may require stricter weight-bearing restriction, and some patients need surgery.

Ankle sprain rehabilitation

Should an acute ankle sprain be managed with complete non-weight bearing?

Most ankle sprains do not require prolonged complete non-weight bearing. Guidelines recommend bracing or taping according to pain and injury severity, with progressive return to weight bearing. Severe sprains may need short-term immobilization early, but prolonged immobilization is usually avoided to protect motion and muscle control recovery.

Anterior knee pain treatment

Does long-standing patellofemoral pain require surgery?

Most patellofemoral pain improves with non-operative care, including load modification, quadriceps and hip strengthening, flexibility work, orthoses, or taping. Surgery is rarely the first choice and is considered only when symptoms are severe and prolonged, non-operative care fails, and a clear structural problem is present.

Read answer
Anterior knee pain treatment

Can orthoses or taping help patellofemoral pain?

They can help some patients, especially when foot-ankle alignment, patellar tracking, or movement-control problems are present. Orthoses, taping, and manual therapy are usually best combined with hip and knee strengthening. Passive treatments alone have limited effect.

Patellar tendinopathy treatment

Can patellar tendinopathy be treated with repeated corticosteroid injections?

Repeated corticosteroid injection around the patellar tendon is not recommended. The patellar tendon bears high jumping and landing loads, and corticosteroids may increase tendon weakening and rupture risk. Treatment usually focuses on load management, quadriceps and hip strengthening, and jump mechanics; persistent cases can be assessed for other options.

Achilles tendinopathy treatment

Can Achilles pain be treated with corticosteroid injection?

Corticosteroid injection into or around the Achilles tendon is generally not recommended because it may increase rupture risk. Achilles tendinopathy is more often treated with load adjustment, calf strengthening, orthoses or heel lifts, shockwave therapy, and similar options. Any injection treatment should be evaluated cautiously.

Anterior shoulder pain

Can long-head biceps tendinitis be treated with injection?

It can be considered after a clear diagnosis. Treatment usually begins with rest, ice, anti-inflammatory pain control, and shoulder rehabilitation. Some patients may receive corticosteroid injection, often with image guidance to improve accuracy. Persistent failure or associated shoulder disease may require arthroscopic treatment, tenodesis, or release.

Sports rehabilitation safety

Who is not suitable for blood flow restriction training?

People with deep-vein thrombosis risk, peripheral vascular disease, severe circulatory problems, active infection, tumor, severe kidney disease, pregnancy, open wounds, or inability to tolerate cuff pressure need caution or avoidance. A doctor or rehabilitation therapist should screen risk before starting.

Read answer
Postoperative management

Do plates or screws need to be removed after foot and ankle surgery?

Not always. Hardware removal depends on pain, soft-tissue irritation, restricted motion, fracture healing, infection risk, and implant location. Asymptomatic hardware can usually be observed. If it affects shoes, sport, or tendon gliding, a doctor should assess the timing and risks of removal.

Read answer
Ankle impingement

Could pinching pain at the back of the ankle be posterior ankle impingement?

Yes. Football, dance, gymnastics, and repeated ankle plantarflexion can trigger posterior ankle pain that worsens with toe-standing, squatting, or kicking. Treatment includes reducing provoking movements, rehabilitation, anti-inflammatory pain control, and imaging assessment; persistent bony or soft-tissue impingement may require arthroscopic treatment.

Read answer
Forefoot pain

Could forefoot pain after running be a plantar plate injury?

Yes. Plantar plate injury often causes pain and swelling under the second metatarsophalangeal joint, floating or drifting of the toe, and worsening with running, jumping, or thin-soled shoes. Treatment includes reducing forefoot load, using a metatarsal pad or stiff-soled shoe, and intrinsic foot strengthening; obvious instability or progressive deformity requires specialist assessment.

Sports-related back and leg pain

What exercise is suitable for lumbar spinal stenosis?

Cycling, swimming, interval walking, core stability, and hip strengthening are often preferred. Leg pain or numbness after walking a distance that improves with bending forward or resting may indicate neurogenic claudication. Progressive weakness, bowel or bladder changes, or saddle numbness requires prompt medical attention.

Read answer
Hip labrum

Does every hip labral tear need repair?

Not always. Treatment depends on symptoms, tear pattern, acetabular coverage, bony impingement, cartilage condition, and sport demands. Mild symptoms can start with rehabilitation and load adjustment. Persistent groin pain, catching, and limited sport with matching imaging and examination may warrant arthroscopic repair or treatment of associated bony problems.

Read answer
After hip arthroscopy

What should be done if pain recurs after hip arthroscopy for impingement?

The pain source should be reassessed, including residual bony impingement, recurrent labral injury, cartilage damage, capsular problems, hip flexor tendinitis, and lumbar-sacral or sacroiliac sources. Management may include rehabilitation adjustment, repeat imaging, diagnostic injection, and, in a small number of patients, revision surgery assessment.

Wrist condition

Is a bump on the back of the wrist a ganglion cyst, and does it need removal?

It may be a ganglion cyst. A painless cyst that does not affect activity can be observed. Aspiration or surgical removal can be assessed when it causes recurrent pain, limits push-up or racquet activity, compresses a nerve, or creates major cosmetic concern. Other soft-tissue masses and joint disease should be excluded before treatment.
