I think the best you can do is to become as familiar as possible with the limitations and potential consequences imposed by whatever structural deviations you might have. This may simply mean fine tuning your technique and/or fitness training, or depending on the severity of your issue, perhaps even evaluating the risk/reward ratio of even playing a physically demanding sport like tennis.
One thing I would pay particular attention to is if the structural deviation predisposes to overuse of any particular muscles as this is something that you have control over.
If possible, find someone with a good understanding of functional anatomy and movement dysfunction to help you through this. If you're brave enough to dig in yourself, Diagnosis and Treatment of Movement Impairment Syndromes by Shirley Sahrmann would be a good place to look. It's not easy reading, though. Especially if your anatomy knowledge is limited.
