Salvation for failure of lateral retinacular release / 中国医师进修杂志

ABSTRACT

Objective To investigate a simple effective way to salvage failure of lateral retinacular release. Methods From March 2007 to May 2009,there were 23 knees of 23 cases for failure after lateral retinacular. All the patients had patellofemoral joint malatignment in some extend,whose patellofemoral joint CT scanned in dynamic. Before curing,the index of patellar tilting angle (PTA) was 19.6° ±5.7° , congruence angle(CA) was 23.6° ± 12.5° , patellar femoral index(PFI)was 2.7 ± 0.8, and hospital special score (HSS) knee score was (74.0 ± 9.2) points,then put on elastic knee sleeves for arranging the malalignment of patellofemoral joints, coincidentally, rehabilitation of vastus medians administered. Results All the patients were followed up for 6 - 26 (11.0 ± 2.3 ) months, 22 cases of 24 knees gained the excellent or good results,1 case had to experience surgery again. After curing, PTA was 11.2° ±3.7°,CA was 6.4° ±7.8°, and PFI was 1.1 ±0.3,escalated HSS knee score was (87.0 ±6.5) points, in these excellent or good patellofemoral joints. Significant difference showed apparently in the cohort through curing (P <0.05). Conclusion Administering elastic knee sleeves along with correct rehabilitation is a simple effective no-incisive cure for salvaging failure of lateral retinacular release.
