Greetings, sorry about the concern. I think you are thinking too much into this. This is not an issue to be worried at this stage unless your walking is troubled.
Next Steps
your abnormal patella tracking will not affect your delivery. it is upto the obstetrician to decide how to go about the delivery.
you can consult a physio to correct the patella and if your physio is good before your delivery your hips and patella abnormal tracking can be corrected.
