Introduction:
The lateral parapatellar approach provides direct access to the pathological area in a valgus knee deformity and allows sequential titrated release of contracted lateral soft tissues during total knee arthroplasty.
Step 1 Preoperative Planning:
Differentiate the flexible and fixed components of the valgus deformity by clinical and radiographic examination.
Step 2 Expansile Lateral Arthrotomy:
Open the knee joint from the lateral side by coronal z-plasty of the lateral retinaculum, oblique lateral tenotomy of the quadriceps tendon, and iliotibial band release.
Step 3 Quadriceps Snip And Joint Exposure:
Perform a quadriceps snip and expose the knee joint.
Step 4 Tibial And Distal Femoral Cuts:
Make proximal tibial and distal femoral cuts in appropriate alignment.
Step 5 Extension Gap Balancing:
A rectangular extension gap is the goal.
Step 6 Flexion Gap Balancing:
Determine the femoral component size and femoral rotation, and balance the flexion gap.
Step 7 Component Fixation:
Confirm tibial rotational alignment, fix the components, and assess patellar tracking.
Step 8 Prosthetic Joint Closure:
Perform closure of the prosthetic joint with expanded lateral structures.
Results:
Between 2003 and 2009, thirty-two knees with clinical valgus deformity of >10° underwent total knee arthroplasty with an expansile lateral arthrotomy technique11.IndicationsContraindicationsPitfalls & Challenges.
