A lateral approach defect closure technique with deep fascia flap for valgus knee TKA
نویسندگان
چکیده
BACKGROUND Routinely, we use a midline skin incision and lateral parapatellar approach of the knee to perform valgus knee TKA (total knee arthroplasty). It is generally very difficult to close the lateral capsular defect after valgus knee TKA, especially for severe valgus and flexion knee deformity. METHODS We describe a new surgical technique to close the lateral capsular defect with a deep fascia flap. From 2009 to 2012, we used the new technique to close lateral capsular defects for nine valgus TKA in eight patients. The wound healing, infection, range of motion, and postoperative X-ray Laurien view were evaluated. RESULTS According to follow-up, we found that this technique can reduce the risk of intra- and postoperative complications (exposure of knee prosthesis, larger subcutaneous hematoma, poor wound healing, and higher risk of infection) and improve clinical outcome of total knee replacement (good range of motion and patellar tracking). There is no need for lateral parapatellar capsule Z-plasty during incision or filling the distal capsular defect with fat pad or composite meniscal-capsular-fat pad. CONCLUSION Closing lateral capsular defect with a deep fascia flap for valgus knee TKA through a lateral parapatellar approach is a new and effective surgical technique.

Total Knee Arthroplasty for Severe Valgus Knee Deformity with a Thin Bowl Shaped Patella
Valgus knee is associated with exaggerated dysfunction of the patello-femoral joint and the lateral compartment of the femorotibial joint, and may be associated with contracture of the lateral soft tissues and laxity of the medial soft tissues. The authors encountered a case of severe valgus knee deformity with a thin bowl-shaped patella. The case was treated with total knee arthroplasty (TKA),...

Background In total knee arthroplasty (TKA) for valgus knees, the decision to use a constrained implant is often made intraoperatively depending on the extent of soft tissue releases performed and residual soft tissue imbalance. The purpose of this study is to determine if preoperative radiographic criteria of valgus knees can predict the extent of soft tissue releases required and the level of...

PURPOSE To report long-term results of total knee arthroplasty (TKA) for valgus knees. METHODS 34 women and 19 men aged 39 to 84 (mean, 74) years with valgus knees underwent primary TKA by a senior surgeon. Of the 78 knees, 43, 29, and 6 had type-I, type-II, and type-III valgus deformities, respectively. A preliminary lateral soft-tissue release was performed, and the tibia and femur were pre...
