Zimmer (NYSE:ZMH) said it agreed to pay an undisclosed amount for Knee Creations LLC and its joint preservation treatment.

The Warsaw, Ind.-based orthopedic medical device company said West Chester, Pa.-based Knee Creations’ subchondroplasty treatment is designed to treat knee pain, whether associated with arthritis or not.

"Zimmer is committed to developing the most comprehensive range of therapies for knee patients, from early intervention and joint preservation products to patient specific instrumentation and personalized joint replacements," Zimmer reconstructive president Jeff McCaulley said in prepared remarks. "The acquisition of Knee Creations’ revolutionary subchondroplasty treatment provides Zimmer with another clinically differentiated offering that addresses an unmet clinical need."

The outpatient subchondroplasty procedure aims to meet the unmet need spanning the gap between early intervention for knee trouble, like anti-inflammatory drugs and arthroplasty, and total joint replacement, according to a press release. A bone void filler is injected to treat subchondral bone marrow edema, which are an early sign of stress fracture. More than 1,500 subchondroplasty procedures have been performed since November 2010, according to the release.
