Effect of Core Stability Exercise on Isolated Patellofemoral Osteoarthritis.
Chondromalacia Patellae
About this trial
This is an interventional treatment trial for Chondromalacia Patellae
Eligibility Criteria
Inclusion Criteria: patients included if they had
- 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 .,
- A grade less than (2) from postero-anterior views on the Kellgren - Lawrence (KL) grading scale.
Exclusion Criteria:
- concomitant pain from tibiofemoral joint or other knee structures .
- current or previous pain in the hip, lumbar spine or foot that had lasted longer than 3 months and/or required intervention.
- a history of lower extremity, pelvis or spine fractures; spine, hip, knee or foot surgeries; hip or patellar subluxation/ dislocation.
- injury to any of knee ligaments or meniscus.
- systemic diseases (e.g. rheumatoid arthritis), neurological conditions or fibromyalgia .
- The professional athletes; people who exercise more than two hours a day or every other day, will be excluded.

Experimental
group A
group B
Patients in this group will receive a traditional therapeutic knee rehabilitation program based on a recent systematic review 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 using clamshell exercise . No emphasis will be placed on stabilizing the core musculature before initiating any of those exercises.
Patients in this group will receive the same program as group (A) plus core stability exercise , but the principles of core 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.
