baseline and six weeks

Study Arms (2)

group A

OTHER

Patients in this group will receive a traditional therapeutic knee rehabilitation program in the form of mini-squatting exercise (up to 45 degree knee flexion measured by a universal goniometer) , strengthening of hip abductors and external rotators

Other: traditional knee rehabilitation program

group B

EXPERIMENTAL

Patients in this group will receive the same program as group (A) plus proximal stabilization exercise

Other: traditional knee rehabilitation programOther: proximal stabilization

Interventions

traditional knee rehabilitation programOther

group Agroup B

proximal stabilizationOther

the principles of proximal stability will be explained to patients before initiation of treatment and patients will be asked to comply with these principles during exercise. These principles include learning how to activate transversus abdominus by abdominal bracing without allowing pelvis tilting and ensure neutral spine and diaphragmatic breathing during exercise.

Eligibility Criteria

Age35 Years - 55 Years

Sexfemale

Healthy VolunteersNo

Age GroupsAdult (18-64)

You may qualify if:

Anterior- or retro-patellar knee pain aggravated by at least two activities that load the PFJ (eg; stair ambulation, squatting and/or rising from sitting) .
Pain during these activities presented on most days during the past month and their pain severity was ≥ 4 on an 11 point numerical pain scale during aggravating activities .,
