Sports Injuries

The majority of sports-related injuries encountered in primary care and community pharmacy are acute soft-tissue injuries — sprains (ligament), strains (muscle or tendon), and contusions (a direct blow bruising muscle and soft tissue) — rather than fractures, stress fractures, or joint dislocations. This chapter covers the pharmacologic and non-pharmacologic management of these acute soft-tissue injuries specifically; chronic overuse tendinopathy (e.g., patellar or Achilles tendinosis, lateral epicondylosis) follows a different, longer-timeline management paradigm and is not covered here. The single most important, and most commonly missed, practice update in this area is that prolonged rest delays recovery: current sports-medicine guidance replaces the older RICE approach with early, protected, optimally-loaded activity (the POLICE protocol), alongside 1st-line acetaminophen and/or NSAID analgesia (oral or topical) and a low threshold for imaging when a small set of validated clinical criteria suggest a possible fracture.^[1]

• Previous injury to the same structure — the single strongest predictor of reinjury, especially without completed rehabilitation.
• Inadequate warm-up or stretching before activity.
• Poor overall conditioning, strength, or flexibility relative to the demands of the sport.
• Rapid increases in training volume or intensity ("too much, too soon"), or a sudden change in training surface or terrain.
• Improper or worn footwear, or inadequate protective equipment.
• Poor technique or biomechanics specific to the sport (e.g., faulty landing mechanics or cutting technique).
• Fatigue — most sports injuries occur later in a training session or competition, when neuromuscular control is reduced.
• Playing-surface and environmental conditions (uneven ground, wet or icy surfaces).
• Participation in a sport involving contact, collision, jumping, or rapid changes of direction.

Differentiating sprain, strain, and contusion

History

• Exact mechanism of injury (twisting, direct blow, forceful contraction) and the position of the limb/joint at the time.
• Timing — when the injury occurred, and whether pain and swelling developed immediately (suggesting more significant structural disruption) or gradually over hours.
• Ability to bear weight or continue activity immediately after the injury versus needing to stop.
• Any audible or felt "pop" or "snap" — raises concern for a complete ligament or tendon rupture.
• Previous injury to the same structure, and whether it was fully rehabilitated.
• Sport, position, and activity level, to inform return-to-play planning.

Physical examination

• Inspection for swelling, bruising, deformity, and any open wound.
• Palpation for point bone tenderness at fracture-specific landmarks (see the Ottawa Ankle/Knee Rules below) and for the specific ligament, muscle, or tendon suspected to be injured.
• Active and passive range of motion, and pain with resisted movement of the involved muscle-tendon unit.
• Joint stability/stress testing specific to the suspected ligament (e.g., anterior drawer and talar tilt for a lateral ankle sprain).
• Neurovascular examination distal to the injury — pulses, sensation, and motor function.
• Assessment of weight-bearing ability, both immediately after the injury (by history) and at the time of examination.

When imaging is not needed

Most Grade I and many Grade II soft-tissue injuries do not require imaging. The Ottawa Ankle and Knee Rules are validated clinical decision rules that identify which patients with an acute ankle or knee injury need radiography to rule out a fracture, and which do not — applying them appropriately reduces unnecessary radiography without missing a clinically important fracture.^[3][4]

When none of the applicable criteria are present, the rule reliably excludes a clinically important fracture and radiography can safely be omitted — proceed directly to non-pharmacologic and pharmacologic management.

• Reduce acute symptoms — pain, swelling, and inflammation.
• Reduce the risk of recurrence by correcting contributing factors (malalignment, muscle weakness, biomechanical or training errors).
• Restore weight-bearing capacity, flexibility, range of motion, strength, and proprioception to the pre-injury baseline.
• Enable the athlete to return to all pre-injury activities comfortably, safely, and fully.

POLICE protocol

• Protection — protect the injured structure from further injury in the first 24 to 48 hours (e.g., a brace, tape, crutches, or a sling), without resorting to prolonged immobilization.
• Optimal Loading — begin weight-bearing and gentle movement as soon as pain and stability allow, progressing gradually; this is the key departure from the older RICE approach and the single most important non-pharmacologic instruction in this chapter — mobilizing early, within the limits of pain, promotes healing and prevents the deconditioning, stiffness, and loss of proprioception that prolonged rest causes.^[1][5]
• Ice — apply an ice pack wrapped in a damp, thin cloth to the injured area for 15 to 20 minutes at a time, at least 4 times daily for the first 48 hours (or longer if swelling continues); never apply ice directly to the skin.
• Compression — an elastic bandage or compression wrap over the swollen area, particularly useful for an ankle sprain; counsel the patient to check for numbness, tingling, or increasing pain distal to the wrap, which signals it is too tight.
• Elevation — elevate the injured limb above the level of the heart when possible, particularly in the first 48 hours.

Correcting contributing factors and structured rehabilitation

• Address muscle imbalances, improper footwear, training errors, and inadequate protective equipment before the athlete resumes full activity.
• Refer to physiotherapy for a structured rehabilitation program, progressing through range of motion, strength, endurance, and proprioception/balance training as tolerated.
• Taping or bracing can support the injured joint during the return-to-activity phase.

Return to activity

Return to play is a graded process, not a single decision point: progress from pain-free activities of daily living, to pain-free range of motion, to strength and proprioception approaching the uninjured side, to sport-specific movement patterns, and only then to full unrestricted competition. Returning to full activity before these criteria are met is a common, preventable cause of reinjury.

Pregnancy

The same treatment principles apply to pregnant and non-pregnant athletes, with a few exceptions. A clinical evaluation is recommended before continuing or initiating an exercise program, and participation in sports with a high risk of contact, falling, or abdominal trauma, along with prolonged supine positioning (particularly beyond the first trimester), should generally be avoided. For analgesia, acetaminophen is preferred. NSAIDs can be used, but must be avoided in the third trimester because of the risk of premature closure of the fetal ductus arteriosus, and used cautiously — lowest effective dose, shortest duration — from approximately 20 weeks' gestation onward given the risk of fetal oligohydramnios from reduced fetal kidney perfusion; ultrasound monitoring of amniotic fluid should be considered if NSAID use extends beyond 48 hours, and the NSAID should be discontinued if oligohydramnios is detected.^[9]

Breastfeeding

Acetaminophen and NSAIDs (outside the pregnancy-specific restrictions above) can both be used safely while breastfeeding. Moderate exercise during breastfeeding does not affect the quantity or composition of breast milk.

Pediatric and skeletally immature athletes

Consider a growth-plate (physeal) injury in any skeletally immature athlete with point tenderness near a growth plate, even after a seemingly minor mechanism, and image/refer accordingly rather than assuming a simple sprain. Avoid ASA in children and adolescents with a viral illness or fever, given the risk of Reye syndrome; acetaminophen and ibuprofen are the preferred analgesics, dosed by weight (see Acute Pain for full pediatric dosing).

Older adults

Acetaminophen or a topical NSAID should be considered first for initial and ongoing treatment of sports- and activity-related musculoskeletal pain in older adults, since this group is more likely to experience an oral NSAID adverse drug reaction (dyspepsia, GI bleeding, renal impairment, blood pressure elevation) — see Osteoarthritis for detailed NSAID risk-management guidance in this population.

Renal or hepatic impairment

Avoid oral NSAIDs in significant renal impairment; a topical NSAID is a reasonable alternative given its much lower systemic exposure, though caution is still appropriate with extensive or prolonged use. Adjust or avoid acetaminophen in significant hepatic impairment per standard dosing caution.

Reassess pain, swelling, and function at intervals matched to the injury grade — days for a Grade I injury, 1 to 2 weeks for a Grade II injury. Confirm the patient is progressing through optimal loading rather than remaining at strict rest, and that analgesic use is trending down as symptoms improve rather than being continued indefinitely. For a topical or oral NSAID used beyond its labelled short-term duration, or for pain that has not improved (or has worsened) within about 7 days, reassess the diagnosis before simply continuing or escalating the same therapy. For a Grade III injury managed conservatively, reassess for orthopedic referral if there is no meaningful improvement after 8 to 12 weeks, or if there is recurrent pain or instability. Before clearing an athlete for full return to play, confirm pain-free range of motion, strength approaching the uninjured side, and restored proprioception/balance — not simply the absence of rest-pain.

1. Reassess the diagnosis — confirm a fracture, complete rupture, or growth-plate injury was not missed, particularly if pain and swelling are not following the expected trajectory for the assigned grade; obtain imaging if this has not already been done.
2. Confirm the patient has actually been following optimal loading, rather than remaining at strict rest or returning to full activity too soon — both errors delay recovery.
3. Confirm the analgesic regimen is adequate — appropriate agent, dose, and duration; consider adding an NSAID to acetaminophen, or trialling a topical NSAID if not already used, before escalating to an opioid.
4. Refer to physiotherapy for a structured rehabilitation program if this has not already happened, particularly for persistent symptoms beyond the expected recovery window for the injury grade.
5. For persistent symptoms despite adequate conservative therapy — especially a higher-grade injury not improving after 8 to 12 weeks, or recurrent instability — refer to a sports-medicine or orthopedic specialist; further options at that level of care may include an imaging-guided corticosteroid or platelet-rich plasma injection, or surgical evaluation, depending on the structure involved, and are beyond first-contact pharmacologic management.
6. Do not add an opioid as the default next step for inadequate pain control — reassess the diagnosis and optimize non-opioid therapy first, given the marginal incremental benefit opioids provide in this setting.

• Prescribing or reinforcing prolonged strict rest or immobilization instead of early, protected optimal loading — this is the single most common outdated practice pattern, and it delays recovery.
• Continuing to use RICE terminology and practice without incorporating optimal loading — the rest component has specifically been updated, not simply relabelled.
• Defaulting to an opioid, including tramadol, for routine sports-injury pain when acetaminophen and/or an NSAID (oral or topical) would be appropriate 1st-line therapy.
• Overlooking topical NSAID therapy as a genuine 1st-line option, particularly in older adults or patients with GI, cardiovascular, or renal NSAID risk.
• Assuming "it's just a sprain" without applying the Ottawa Ankle/Knee Rule criteria (or equivalent point-bone-tenderness/weight-bearing assessment) when they apply, and missing a fracture.
• Continuing an oral NSAID at a fixed dose for many weeks for what should be a short, symptom-driven course.
• Missing early signs of compartment syndrome or neurovascular compromise because they were attributed to "just" swelling from a sprain or strain.
• Giving ASA to a child or adolescent athlete with a viral illness or fever.
• Clearing an athlete for full return to play based on pain relief alone, without confirming restored strength, range of motion, and proprioception.

General oral acetaminophen/NSAID/opioid dosing follows the same principles as Acute Pain; the doses below reflect sports-injury-specific practical guidance and duration.

Oral analgesics and NSAIDs

Topical NSAID

Provides pain relief comparable to an oral NSAID for a localized injury, with substantially lower systemic drug exposure than an equivalent oral NSAID dose — a genuine 1st-line option, not only a fallback for patients who cannot take an oral NSAID.^[6]

Muscle-relaxant combination

An option specifically when muscle spasm is a prominent component of a strain (e.g., a low back or neck strain), as an adjunct to — not a replacement for — POLICE and 1st-line analgesia.

Weak-opioid combination (special situation only)

Not routine therapy for a sports-related soft-tissue injury — reserve for a genuinely severe injury or true intolerance of 1st-line agents, per current opioid-stewardship guidance for acute musculoskeletal pain. See Acute Pain for the complete opioid analgesic ladder and dosing.^[7]
