Assistive Patellar Stabilizers

It is estimated that up to 40% of knee injuries are caused by patellar problems, which disturb movement especially during squatting or descending stairs and cause serious anterior knee pain (Rothermich MA et al., 2015).

Patellar tracking is guided mainly by the quadriceps and patellar tendon which presents the motion of the patella relative to the femur or femoral groove during knee flexion and extension. However, various forces on the connective tissues around the patella may cause tracking abnormalities, which are related to many disorders of the patellofemoral joint.

Realign the patella

Physicians and therapists realign the patella and help patients regain patellar mobility through professional techniques for applying corrective forces on the patella. Maintaining the corrected position of the patella after treatment until the next appointment may enhance the prognosis.

Assistive patellar stabilizers

Provide sustained forces and protection for the patella, maintaining proper patella tracking during knee movements in daily lives. OPPO Medical offers guiding principles to assist medical professionals with selection of the most appropriate patella brace for patients and achieve better prognosis.

Shift out of alignment

Patellar subluxation due to structural imbalance or pre-trauma requires the 2923 C-knee Stabilizer with adjustable C-shaped pad as a barrier against patellar displacement. The pad may be placed according to the subluxation condition and direction of the patella. Medical professionals are required for this decision making.

 

2923 C-knee Stabilizer

  • High density weave around kneecap helps stabilize it in place
  • Detachable panel fits different severity and direction of patellar displacement
  • Bilateral spiral stays provide additional knee stability and better support
 
Indications
  • Patellar lateral subluxation or medial subluxation
  • Patellar instability

Abnormal tracking

Abnormal patellar tracking resulting from muscular imbalance requires the 2323 Premium C-pad Stabilizer. It offers stability in proper tracking and its delicate knit provides more sensory inputs to elevate knee control.

2323 Premium C-pad Stabilizer

  • 3D energizing pattern around medial patella stimulates sensory inputs of vastus medialis obliquus
  • Bilateral spiral stays provide additional knee stability and better support
  • Skin-friendly structure offers superior comfort
 
Indications
  • Patellofemoral pain syndrome
  • Patellar maltracking

Abnormal tracking with rotation

Abnormal patellar tracking with patellar rotation requires the 1028 Patella Tracking Support. Its unique centralized reinforced straps can be adjusted to different degrees of tension to finely adjust rotation of patella as desired.

1028 Patella Tracking Support

  • Adjustable reinforced straps centralize medially to provide counter-rotation force for patella
  • Dynamic ventilated material and open patella design are suitable for sports use
  • Wrap-around design for easy wear
 
Indications
  • Patellofemoral pain syndrome
  • Patellar maltracking combined with or without patellar rotation
