Introduction
Treatment of patients with degenerative knee and varus malalignment presents a difficult clinical problem. Arthroscopic debridement or chondral resurfacing in combination with a medial opening wedge high tibial osteotomy seems to be a viable treatment option.
Study design
Retrospective review of our data pool from the last 4 years.
Material and Methods
We followed a group of 31 consecutive patients (mean age 49 years; range 35 - 63 years; 22 men, 9 women) with varus malalignment and intraarticular meniscal or chondral lesions who were treated with arthroscopic debridement or chondral resurfacing (an abrasion or microfracture technique) combined with a medial opening wedge high tibial osteotomy. All patients had >5 degrees of varus malalignment. Patients were evaluated pre,- and postoperatively with the Lysholm and Tegner Score for function and daily activities at a minimum of 6 month follow-up.
Results
Twenty-eight of 31 patients (90%) were available for the follow-up (average 26 months; range, 6 to 48 months). Lysholm scores improved from a preoperative score of 45 to 78 at follow-up. The average Tegner score was 5.0.
Conclusions
Combining a medial opening wedge high tibial osteotomy with an arthroscopic debridement or microfracture chondral resurfacing procedure in the varus knee is an effective method of decreasing pain and increasing function at a mean of 2 years follow-up.
