Lateral parapatellar approach to TKA shows good mid-term results
Researchers from India confirmed that a lateral parapatellar approach without tibial tubercle osteotomy for total knee arthroplasty in fixed valgus knees provides good mid-term results, according to results of this study.
“In conclusion, modified Keblish approach is an effective surgical technique and provides good functional results. This lateral approach with coronal Z-plasty of the lateral retinaculum capsule complex and quadriceps snip without tibial tubercle osteotomy could achieve adequate surgical exposure, titrated release of contracted lateral soft tissue structures, good patellar tracking and satisfactory lateral joint closure in valgus arthritic knees requiring primary arthroplasty,” Bhavia R.J. Satish, MS, DNB, and colleagues wrote in the study. “This approach provides satisfactory mid-term functional results, can be employed in severe fixed valgus deformities and can potentially preserve the lateral soft tissue stabilizers necessary for long-term prosthetic stability and survival.”
Satish and colleagues analyzed the results of 32 arthritic knees with a valgus deformity at 5-year follow-up, according to the abstract. The surgeons preserved the tendon popliteus or lateral collateral ligament in 30 cases and no knees had late instability or required revision. At follow-up, valgus alignment improved from 25.4° to 4° and the mean Knee Society Score increased from 34 points to 95 points.
