Andrew Bynum to receive knee treatment in Germany

Philadelphia 76ers center Andrew Bynum will go to Germany in early September to have the same procedure on his knee that Kobe Bryant, Grant Hill and Alex Rodriguez have undergone, the Philadelphia Inquirer reported.

Bynum, traded from the Lakers to Philadelphia last week in a four-team deal, has had surgery on both knees. It is unknown whether the procedure will be performed on one knee or both. According to the Inquirer, a person familiar with the situation said Bynum’s knees are fine and the procedure, which has been used to treat osteoarthritis, is nonsurgical.

The procedure, known as Orthokine/Regenokine, is to be performed by Peter Wehling, founder of the Center for Molecular Orthopaedics in Dusseldorf. Though it is not yet performed in the United States, it is similar to another blood-spinning treatment that has gained popularity, known as platelet-rich plasma therapy. In that procedure, the goal is to produce a high concentration of platelet cells, which are believed to speed the healing process. Wehling’s procedure differs in that he uses the patients’ own blood to produce a high concentration of anti-inflammatory proteins, rather than the platelets, which he injects into the troubled joint.

An accreditation warning issued to Penn State is serious and necessary given the issues raised by a recent child sex-abuse scandal, but the school is unlikely to lose the all-important designation, experts said Tuesday.

They also expect the university to comply quickly with demands to show that its governance, finances and integrity meet standards set by the Middle States Commission on Higher Education.

The Philadelphia-based commission issued the warning last week based on the school’s handling of molestation allegations against Jerry Sandusky, a former assistant football coach convicted in June of sexually abusing 10 boys.

Concerns include whether Penn State trustees provide sufficient oversight of the administration, the strength of the university’s ethical standards and the school’s compliance with government policies, such as those requiring campus crime reports, said Middle States spokesman Richard Pokrass. The commission also wants the school to address its financial status in light of a $60-million penalty imposed by the NCAA and any lawsuits from Sandusky’s victims.

Louisiana State Coach Les Miles declined to close the door completely on the possibility, however remote, of Tyrann Mathieu playing football for the Tigers in 2013.

“Tyrann can be a student at LSU,” Miles said after practice Tuesday, adding that he is “not in any way speculating” about whether Mathieu could conceivably play for the Tigers again. “He will not be on this football team this year — I guarantee that’s a fact. So I have no idea beyond that.”

Andy Roddick developed back spasms during his opening match at the Western & Southern Open at Mason, Ohio, setting up a two-set loss that left questions about his health heading into the U.S. Open.

The National Hockey League Players’ Assn. has made its first proposal in the latest round of collective bargaining talks with the NHL.

The union says its proposal to the league includes a smaller percentage of revenues for players and an expanded revenue sharing program to help struggling teams

Donald Fehr, the executive director of the union, says players are set to surrender as much as $465 million in revenue under the proposal if the league continues to grow at an average rate. He says that number could balloon to $800 million if the league grows at the same rate it has over the last two seasons.

That proposal called for lowering the players’ share in revenue and introducing new contract restrictions, including a five-year cap on deals.

The current CBA expires Sept. 15. The NHL has said there will be a lockout if a new agreement isn’t in place by then. The regular season is slated to start on Oct. 11.
