So right meniscus tear preceded by 2 left rib fractures preceded by chronic left anterior hip pain when cleaning or squatting ?
Right off the bat I'd start by integrating some hip focused unilateral exercises and just continue correcting any length tension imbalances. Soft tissue work, stretching, re-establishing proper movement pattern in squat and clean. Video record your movements for your own analysis and or have another trained eye take a look as well. IMO you can better prescribe corrective protocol when you establish what your doing wrong in your movement pattern.
By the way did you figure out what caused or led up to the meniscus tear? That might a great place start too?
