Spain's King Juan Carlos I is showing "very positive" improvement and "is getting up and moving naturally, with the help of two crutches," according to the medical report released Sunday by Javier de Joz, the director of the Madrid medical center where the monarch is recovering from hip surgery.

The report - signed by the lead orthopedist treating the king, Angel Villamor, and the chief of the Royal Palace's Medical Service, Miguel Fernandez-Tapia Ruano - said that Juan Carlos rested during the night and "early in the morning he underwent his first treatment and is continuing with the scheduled exercise program."

"The recovery is progressing satisfactorily and, currently, he is getting up and moving naturally, with the help of two crutches," the statement added.

The Spanish monarch underwent hip replacement surgery under general anesthesia last Friday.

The operation lasted 90 minutes and doctors were able to deal with the deterioration of the left hip joint caused by osteoarthritis by implanting an artificial hip.

This is the third operation in the same area the king has undergone and his sixth overall in the past two-and-a-half years. Most of them have been to treat orthopedic issues resulting from accidents or problems related to bone wear and tear.

On Sunday, the king received several visitors, including Prime Minister Mariano Rajoy. Members of the royal family who stopped by included Queen Sofia and their two daughters, Princess Elena and Princess Cristina, along with the latter's husband, Iñaki Urdangarin, and their son Juan Valentin. Also coming by to check on the monarch were Crown Prince Felipe and his wife, Princess Letizia, accompanied by their two children, Leonor and Sofia. EFE
