Abstract
Purpose : The purpose of this study was to the functional and radiographic outcomes of isolated arthroscopic partial meniscectomy between patients with generalized joint laxity and patients with normal joint laxity at 5-year minimum follow-up evaluation and to determine the influence of preexisting generalized joint laxity on the results of arthroscopic partial meniscectomy. I used 2 homogenous groups, defined with strict criteria. Materials and Methods : The Beighton and Horan criteria were used to determine generalized joint laxity. 21 patients with excessive joint laxity who met the criteria (Group L) were carefully matched to 21 patients with normal joint laxity who met the established criteria (Group N) for sex, age and medial/lateral meniscus injury. The patients were evaluated clinically using the International Knee Documentation Committee (IKDC) grade and the Lysholm score. Radiologic arthritic changes at final follow-up were evaluated by use of the classification of Tapper and Hoover. Results : Preoperative and postoperative Lysholm score and IKDC grades were similarly excellent in both groups. Osteoarthritic changes were shown in 38% of the patients in group L and in 29% of the patients in group N lateral arthroscopic partial meniscectomy. There were more osteoarthritic changes in respect of frequency and severity in patients with generalized joint laxity than in patients with normal joint laxity, but this finding was not statistically significant. Conclusion : Clinical and functional results are similar in both groups. Although no statistically significant difference was found between the groups, a trend toward higher progress of radiologic sign of osteoarthritis in patients with generalized joint laxity was observed. Studies with a longer follow-up are needed to conclude whether the preexisting generalized joint laxity eventually will influence the clinical and radiographic outcomes of arthroscopic partial meniscectomy.
