Hot Topics in Sports Medicine 2015• Sports concussion

– Diagnosis– Treatment

• Knee pain due to osteoarthritis + meniscus tear– Exam– Treatment evidence

• Rotator cuff tears– Physical examination evidence

Concussions are common US military and traumatic brain injury

• 320,000 blast-related TBIs from wars in Iraq and Afghanistan (MacDonald CL et al. Detection of Blast-Related Traumatic Brain Injury in US Military Personnel, New England Journal of Medicine 2011.)

• mTBI accounts for 80-90% of TBI in civilian and military populations (Levin HS and Diaz-Arrastia RR. Lancet Neurol2015; 14: 506-17.)

Concussion numbers increasing

Marin JR et al. Trends in visits for traumatic brain injury to emergency departments in the United States. JAMA. 2014 May 14;311(18):1917-9.

Concussion legislation• California: Education Code 49475 (effective

1/2012)1. Student athletes and guardians sign a concussion

information form yearly2. Athlete suspected of having concussion removed at

time of injury for the rest of the day3. Athlete can return only after cleared by healthcare

professional trained in evaluation and management of concussion

Case #1• 40 y/o woman presents to your office for ER follow-up

two days after bike accident.• Slid out while crossing streetcar tracks on wet city

streets. • No loss of consciousness.• Taken by ambulance to ER.• Had trauma work-up including head CT (-).• Has headache, fatigue, dizziness, light sensitivity.

Trouble staying focused at work, sleeping more than usual.

• Normal neck and neurologic exam.

Concussion definition• Type of mild traumatic brain injury• Blow to head, neck, body � force to head• Rapid onset of neurologic impairment• Symptoms usually resolve in weeks, spontaneously,

but in some cases can be prolonged.• May or may not include loss of consciousness.• CT and MRI studies are normal

Clinic concussion evaluation• History of injury• PMHx ADHD, anxiety,

depression, head injury• Clinical status: improving or

worsening since time of injury?

• Neck and neurological exam

• Age > 60• GCS < 14 initially or < 15

two hours post injury• Vomiting more than once• Seizure• LOC• Focal neuro deficit• Suspected skull fx• Severe headache

• Decreased alertness after initially lucid

• High velocity injury (hit by car, fall from height)

• Comorbid illness (cirrhosis, diabetes, immunosuppression)

• Pregnancy• Anticoagulants

Adapted from Levin HS and Diaz-Arrastia RR. Lancet Neurol 2015; 14: 506-17, using NICE 2014 and 2008 American College of Emergency Physicians/US CDC policy statement.

How severe is my concussion?• Concussion grading is retrospective

– Historically concussions were graded on the sideline based on amnesia and LOC at time of injury.

– American Academy of Neurology, 1997– Cantu, 2001

– Studies have shown these factors not to be predictive of recovery.

• Only when the athlete recovers can you tell how severe the concussion was

Symptom resolution• Athletes become asymptomatic in 1-2 weeks

(Williams RM et al. Sports Med. 2015 Mar 28.)• Recovery in athletes may be faster than in others

(Levin HS and Diaz-Arrastia RR. Lancet Neurol 2015; 14: 506-17.)• Pre-existing neuropsychiatric disorder associated

with symptoms > 3 months (Levin HS and Diaz-Arrastia RR. Lancet Neurol 2015; 14: 506-17.)

Case #1• 40 y/o woman presents to your office for ER follow-up

two days after bike accident.• Slid out while crossing streetcar tracks on wet city

streets. • No loss of consciousness.• Taken by ambulance to ER.• Had trauma work-up including head CT (-).• Has headache, fatigue, dizziness, light sensitivity.

Trouble staying focused at work, sleeping more than usual.

• Normal neck and neurologic exam.

How would you treat this patient?A. Order urgent head CT to rule out subtle

post traumatic bleed, return to clinic after CT.

B. Rest from work and biking, return to clinic 1 week.

C. Return to work but rest from biking, return to clinic in a month.

D. Return to work and biking.O r d

Return to school/work progression

No school. OK to do light reading, little bit TV, drawing, cooking as long as doesn’t worsen symptoms.

15 min cognitive activity at a time.

Return to full day of school.

• 188 patients followed x 2 years• Primary endpoint WOMAC score (knee pain + fxn)• Avg age 60, 2/3 female, BMI 31• Excluded bucket handle meniscus and severe

varus or valgus alignment

Interventions• Control

– PT: 1 hour/week x 12 weeks

– Home ex program 2x/day

– Instruction on ADLS– Self management

arthritis education reading + videotape

– Medications (APAP, NSAIDs, hyaluronic acid injections)

• Arthroscopic surgery– Irrigation with saline– 1 or more of the

following:• Debridement or excision

of degenerative meniscus tears

• Removal loose bodies, chondral flaps, bone spurs

– Medical and physical therapy like controls

Katz JN et al. Surgery versus physical therapy for a meniscal tear and osteoarthritis. N Engl J Med. 2013 May 2;368(18):1675-84.

Surgery vs PT for meniscal tear and OA• Multicenter RCT• 351 patients with meniscus tear + OA• Meniscus sxs (clicking, popping, catching, giving

way, joint line pain, pain with twisting)• Avg. age 60 years• 50% men, 50% women• Primary outcome = change in WOMAC physical-

function score between groups at 6 mo

Interventions• Control (PT)

– Usually 6 weeks– 3-stage program

• APAP, NSAIDs, intraarticular steroid injections as needed

• Arthroscopic partial meniscectomy (APM)– Trim damaged meniscus

back to stable rim– Remove loose cartilage

and bone• PT protocol• APAP, NSAIDs,

intraarticular steroid injections as needed

Conclusions• 30% crossed over from PT to APM at 6mo

– These people had WOMACs that didn’t improve until crossover

• No sig difference in adverse events• PT and APM are reasonable options with similar

outcomes for these patients (with allowed cross over if not achieving relief with PT)

• Starting with conservative approach is reasonableKatz JN et al. Surgery versus physical therapy for a meniscal tear and osteoarthritis. N Engl J Med. 2013 May 2;368(18):1675-84.

Thorlund et al. Arthroscopic surgery for degenerative knee: systematic review and meta-analysis of benefits and harms. BMJ. 2015 Jun 16;350:h2747.

• Benefits and harms of knee arthroscopy for degenerative knees• Meta-analysis of RCTs to determine benefit and including cohort

studies to determine harms• Arthroscopy effect size 2.4 mm on a 0-100 mm visual analog scale.

No effect after 6 months.• Harms: DVT, PE, infection, death• Conclusion: “These findings do not support the practise of

arthroscopic surgery for middle aged or older patients with knee pain with or without signs of osteoarthritis.”

Osteoarthritis with meniscus tear• Meniscus tear is part of the natural history of osteoarthritis• Treat as osteoarthritis initially• Imaging: Start with xray, MRI if exam c/w meniscus tear and not

improving with PT• Could consider arthroscopic meniscus surgery if weight loss, PT,

medications, injections not helping or if patient prefers surgical treatment but effect may be small and of short duration.

Caveats: Who to Refer• Younger patients• Bucket handle meniscus tears

– Knee locked due to meniscus blocking joint movement

• Mechanical symptoms: locking, catching• Failure of nonoperative knee OA treatment

Non op treatment knee OA 2015• Mainstay

– Weight loss– Exercise– Pain control: APAP, NSAIDs

(topical vs oral), injections• Increased concern use of

– APAP– Opioids

• Stronger evidence developing for– Duloxetine– Tai Chi

• Controversial – Unloader brace– Specific types of

rehab/exercise

Case #357 y/o RHD man presents with R shoulder pain that started after he slipped and fell 3 months ago. Pain at R deltoid. He tried physical therapy without benefit. Waking at night from sleep due to pain.

Differential diagnosis?

Rotator cuff disease in primary care• The 3rd most frequent musculoskeletal reason

patients present to the office• The most common cause of shoulder pain in

patients in the US primary care settings

Whittle S, Buchbinder R. In the clinic. Rotator cuff disease. Ann Intern Med. 2015 Jan 6;162(1):ITC1-15.

What is rotator cuff disease?• Impingement• Tendinitis/tendinopathy• Partial thickness tear• Full thickness tear

6/23/2015

13

Rotator cuff disease treatmentMost do well with conservative treatment• Impingement• Tendinitis, tendinopathy• Partial tear • Full thickness tear � Consider ortho referral.

PT+/- Injection

+/- Medication

Rotator cuff surgery outcomesBetter if (acute) full thickness rotator cuff tears fixed earlier than later • Smaller tear size associated with better

outcome (Cofield RH et al. Surgical repair of chronic rotator cuff tears. JBJS 2001.)

• Less fatty infiltration and muscle atrophy associated with better outcome (Gladstone JN et al. Fatty infiltration and atrophy of the rotator cuff do not improve after rotator cuff repair and correlate with poor functional outcome. AJSM 2007.)
