Patellar disorders are common and painful. Although in many cases no precise cause for the pain is identified, poor patellar tracking, leading to imperfect distribution of forces in the patello-femoral joint, is a frequent finding. Tightness of the lateral retinaculum or anatomic predisposition for lateral tracking (e.g., femoral anteversion or an elevated Q angle) also places patients at increased risk for patellar pain. Most patients with patellar disorders will improve with simple programs of activity modification, therapy, and other nonsurgical modalities. Nonoperative therapy can include short arc quadriceps strengthening and stretching regimens, the application of ice, and the use of knee sleeves. Surgical treatment spans a wide range of choices, each tailored to specific diagnoses. These operations are reserved only for patients for whom conservative measures fail.

This prospective study determined whether selected anatomic measures identified women at increased risk of patellofemoral pain syndrome (PFPS) and shin splints (SS). Ten anatomic measures were performed on 748 women before basic training at the Marine Corps Recruit Depot (MCRD), Parris Island, South Carolina. Recruits were then followed throughout basic training for occurrence of injuries. Logistic regression modeling indicated that a left hip internal rotation range of motion (ROM) < or =25 degrees and > or =46 degrees, a right Q angle > or =20 degrees, and left knee hyperextension ROM > or =6 degrees were positively associated with PFPS. Whereas left dorsiflexion ROM > or =21 degrees was associated with SS, right Q angle > or =20 degrees was inversely associated with SS. These findings suggest that multiple anatomic measures can be used to identify women entering MCRD basic training at risk for PFPS and SS injuries.

Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with signs of patellofemoral osteoarthritis (PFOA). A key factor in PFPS development is dynamic valgus of the lower extremity, which leads to lateral patellar maltracking. Causes of dynamic valgus include weak hip muscles and rearfoot eversion with pes pronatus valgus. These factors can also be observed in patients with PFOA. The available evidence suggests that patients with PFP are best managed with a tailored, multimodal, nonoperative treatment program that includes short-term pain relief with nonsteroidal anti-inflammatory drugs (NSAIDs), passive correction of patellar maltracking with medially directed tape or braces, correction of the dynamic valgus with exercise programs that target the muscles of the lower extremity, hip, and trunk, and the use of foot orthoses in patients with additional foot abnormalities.

Patellofemoral pain syndrome (PFPS) is one of the most common diseases that cause pain in the knee joint. At present, there is no specific diagnostic measure. The diagnosis of patellofemoral pain syndrome may be considered when imaging is performed without cartilage, ligament and soft tissue injuries. The etiology includes abnormalities of the patellar motion caused by various anatomical abnormalities, such as abnormal patellar position, increased Q angle, and excessive valgus foot. Dysfunction of the lower extremity muscles such as the imbalance of the four biceps and the dysfunction of the gluteal muscles also play an important role in the development of patellofemoral pain syndrome. At present, there are many treatments, and the exercises of four biceps exercises and hip abductor exercises are aimed at improving the dynamic stability of patella; The muscle patch and the patellar brace mainly reduce the pressure of the patellofemoral joint by improving the patellar trajectory; Foot orthopedic pads are used primarily in patients with valgus feet. After the conservative treatment is ineffective, the patellar lateral retinaculum can be loosened under arthroscopy. Because the patellofemoral pain syndrome is caused by the combined effects of various etiologies, a variety of treatments are helpful to improve the therapeutic effect.

Recurrent patella instability is a common condition that may potentiate substantial knee dysfunction resulting in loss of time from work and sports. There are numerous factors that contribute to recurrent patella instability including tearing of the medial patellofemoral ligament (MPFL), shallow trochlea, valgus alignment, externally rotated tibia tubercle, ligamentous laxity, elevated Q angle, and increased tibial tuberosity trochlear groove distance. Reconstruction of the MPFL has been shown to restore patella stability where concomitant pathology is within acceptable limits. Major complications include recurrence from inadequate MPFL reconstruction or failure to address other pathology, patella femoral pain from over constrained MPFL or unaddressed cartilage defects to the patella femoral compartment, or patella fracture. This technique provides a reproducible method of restoring patella stability through MPFL reconstruction while minimizing stress risers in the patella by using suture anchor fixation that creates a ligamentous footprint instead of tendon healing into a socket on the patella.
