The Basketball Player's Ankle and Return-to-Play Decision
A 16-year-old guard lands on an opponent's foot during a game and rolls her right ankle. She has immediate pain, swelling within 10 minutes, and cannot continue. There is tenderness over the lateral ligaments, no bony tenderness over the malleoli, and she can bear weight with a limp. A physiotherapist diagnoses a grade 2 lateral ankle sprain. She is keen to play in a semi-final in 12 days. Her coach wants her back for a key training session in 5 days. She currently has reduced single-leg balance on the right (she can hold 10 s versus 45 s on the left) and her hop test is 70% of the uninjured side.
1. Explain the immediate management of this injury and justify why the coach's request to return to a key session in 5 days is likely to be inappropriate.

Immediate management follows the principles of protection, relative rest, ice, compression, elevation, and referral. Ice for short periods (for example 15–20 min every 2–3 h) reduces pain and blood flow; compression and elevation limit swelling. Relative rest with crutches if needed protects the healing ligament, and referral ensures appropriate diagnosis and a rehabilitation plan. Anti-inflammatory medication should only be used on medical advice.
A grade 2 sprain involves partial tearing of the lateral ligaments, with tissue healing progressing through inflammation, repair, and remodelling. At 5 days the player is still in the early repair phase: the ligament has minimal tensile strength, proprioception is impaired, and the ankle is swollen and stiff. Her single-leg balance is 10 s versus 45 s and her hop test is 70% of the uninjured side, both indicating significant deficits in proprioception and dynamic stability.
Returning to a key training session at day 5 would load healing tissue before it can tolerate force, risking re-injury, prolonged symptoms, and chronic instability. The relevant principle is that return to sport requires functional criteria, not just elapsed time or the player's motivation. The 12-day semi-final is a more realistic target, and even then only if objective criteria are met.
2. Outline the criteria and progression the player should meet before returning to the semi-final, and explain how each criterion reduces re-injury risk.

Return should be criteria-based and staged.
Pain and swelling: minimal pain, no swelling, full pain-free range of motion. Persistent swelling impairs joint position sense and strength.
Strength: calf and peroneal strength within about 90% of the other side on manual or dynamometer testing. Weakness in the peroneals reduces the ability to resist inversion.
Balance and proprioception: single-leg balance on the injured side approaching the uninjured side (for example within a few seconds on a timed test, and successful on unstable surfaces). Impaired proprioception is a major modifiable risk factor for recurrent sprains.
Functional and hop tests: hop for distance and a series of single-leg hops at 90% or more of the uninjured side, with good landing control. This demonstrates the ankle can absorb and produce force under sport-like loads.
Sport-specific progression: straight-line running, then change of direction, then jumping and landing, then controlled contact, each stage pain-free and without swelling the next day.
Prevention: a balance and proprioception programme continued through the season, an external ankle brace or taping for the semi-final, and adequate conditioning. These measures reduce the risk of recurrence.
Only when these criteria are met should she play, and she should be monitored for swelling after training.
