Western Bulldogs backman Dale Morris has revealed the extraordinary lengths he's going to as he attempts a miraculous recovery from a serious knee injury, including consuming one litre of bone broth a day. 

The catch is, he has no idea if it's working, and won't for another couple of weeks until his leg brace comes off.

After damaging the anterior cruciate ligament in his left knee at training in mid-March, the 36-year-old opted to avoid surgery, as he did last year when he had a similar injury in the opposite knee.

His leg is kept in a brace that keeps it straight and the 2008 All Australian explained why when speaking to Channel Seven.

"The knee is in the perfect position. The brace holds it all there," Morris said.

"There's a lot of fluid in the knee and for the ACL to heal you want the blood clots to form and to be able to scar up, to heal, to strengthen the ACL.

"If you move your knee, it kind of washes all those blood clots out. To lock it in place gives it the best opportunity to heal."

His wife Gemma is making bucket loads of chicken and turkey broths, and Morris is aiming to consume one litre per day. It's all part of the healing process.

"You boil the bones down and all the ligaments and cartilage and bone marrow all goes into this soup. You take the bones and the meat out, boil it down into this gelatinous substance and that's great for your body to heal," Morris said.

"It's good for your body anyway, but even more so for healing ligaments and good for joints.

"When I found out I'd done my ACL, after I rang her and you have your little cry on the phone - 'why me' sort of thing - you look at what's next.

"She goes 'I'm going to go home and I'm going to cook you the biggest pot of bone broth you've ever seen, and you're going to drink it and you're going to get better'."

In around 10 days time, Morris will be allowed to bend his knee 30 degrees.

Whether the efforts he and his wife have put in are rewarded remains to be seen.

"It's all unknown. I don't know if this is healing. I don't know if this is getting better," Morris said.

"I think it is and I'm hoping it is and I'm sending out all those positive vibes that it's healing, but there's no guarantees with what we're doing."

If the knee is not getting better, going under the knife might be necessary.

This type of recovery method is rarely used, but the Bulldogs had a test case before last year's situation with Morris.

Daniel Giansiracusa suffered a partially torn ACL in his right knee in December 2007, returned for round one, played every game that season and didn't retire until 2014.

Morris wants to follow that example.

"Hopefully this can heal and I'll get back," Morris said.
