Everyone tells me that full squat will lead to a injury on knees and it's better to do parallel squat.... But my knees feel much better when doing full squat than parallel. For me, when doing parallel squat, knees will break my descent and be under big stress at bottom position, but on the contrary, hip will take the stress when doing full squat. The only problem for full squat is that waist may be a little bent when at the bottom.

What's your opinion guys?

Who is EVERYONE??
I think there are a lot of us on the WBB that like to Full Squat...
My joints love it.. and I have never gotten a knee injury via squatting...
I have playing football, crashing on a motorcycle and a car crash.. but never full squatting...

Everyone in my gym :) They call their action "deep squat" but it's just half squat to me...

Yeah, you pretty much already nailed the answer you just seem unsure of yourself.

Your waist shouldn't bend.

My knees crackle when my ass touches my calves when I squat. BTW I squat bare footed, it's been mentioned it's real bad for the knees. So I'd just put my heels on plates while squatting.

"My knees crackle when my ass touches my calves when I squat"

Do you mean that they crackle every time when you reach the bottom, or just got badly injured once?

full squats are no different from parallels. (as far as injuries are concerned)

My knees always crackled, even when I was younger, I would remember my knees making that "Crackle" sound when I would squat down.

Although it doesn't crackle if I'm squatting just about parallel, or a bit below parallel.

Except that the knee joint absorbs more of the braking force at parallel than at the bottom of a full squat.

SkinnySadMan,

Same to me. But they won't crackle after a few sets warming up. I used to play basketball - this sport is quite a killer on knees.

i have occasional knee discomfort and anecdotally speaking, the more leg work I have done, the less my knee has bothered me

There are several schools of thought on squat depth. Many misinformed individuals caution against squatting below parallel, stating that this is hazardous to the knees. Nothing could be further from the truth. (2) Stopping at or above parallel places direct stress on the knees, whereas a deep squat will transfer the load to the hips,(3) which are capable of handling a greater amount of force than the knees should ever be exposed to. Studies have shown that the squat produces lower peak tibeo-femoral(stress at the knee joint) compressive force than both the leg press and the leg extension.(4) For functional strength, one should descend as deeply as possible, and under control. (yes, certain individuals can squat in a ballistic manner, but they are the exception rather than the rule). The further a lifter descends, the more the hamstrings are recruited, and proper squatting displays nearly twice the hamstring involvement of the leg press or leg extension. (5,6) and as one of the functions of the hamstring is to protect the patella tendon (the primary tendon involved in knee extension) during knee extension through a concurrent firing process, the greatest degree of hamstring recruitment should provide the greatest degree of protection to the knee joint. (7) When one is a powerlifter, the top surface of the legs at the hip joint must descend to a point below the top surface of the legs at the knee joint.

Knee injuries are one of the most commonly stated problems that come from squatting, however, this is usually stated by those who do not know how to squat. A properly performed squat will appropriately load the knee joint, which improves congruity by increasing the compressive forces at the knee joint. (8,(9) which improves stability, protecting the knee against shear forces. As part of a long-term exercise program, the squat, like other exercises, will lead to increased collagen turnover and hypertrophy of ligaments. (10,11) At least one study has shown that international caliber weightlifters and powerlifters experience less clinical or symptomatic arthritis. (12) Other critics of the squat have stated that it decreases the stability of the knees, yet nothing could be further from the truth. Studies have shown that the squat will increase knee stability by reducing joint laxity, as well as decrease anterior-posterior laxity and translation. (13,14) The squat is, in fact, being used as a rehabilitation exercise for many types of knee injuries, including ACL repair. (15)
