Tennis - German tennis star Anna-Lena Friedsam has had to undergo another surgery on her shoulder, which she had earlier operated upon in 2016. The former World No. 45 is now ranked No. 369 in the world and took to Instagram to announce that she underwent surgery on Saturday.

Friedsam posted the update - "Yesterday I was operated on the shoulder one more time. The operation went well. It was not an easy decision, but the OP showed that it was the right one. The next months I will invest all my strength in a healthy and stable recovery.

Thanks to all the lovely people who are going through this time with me a second time!"

Gestern wurde ich ein weiteres Mal an der Schulter operiert. Die OP ist gut verlaufen. Es war keine einfache Entscheidung, aber die OP hat gezeigt, dass es die Richtige war. Die nächsten Monate werde ich all meine Kraft in eine gesunde und stabile Genesung investieren. Danke an all die lieben Menschen, die mit mir ein zweites Mal durch diese Zeit gehen! 🍀❤️🍀 A post shared by Anna-Lena Friedsam (@friedi_and_friends) on Apr 7, 2018 at 7:02am PDT
