Purpose The aim of this study was to analyze patient-reported outcomes in those undergoing the triad of simultaneous osteotomy, meniscal transplantation, and articular cartilage repair. Methods: Patients undergoing simultaneous meniscal transplantation, distal femoral or proximal tibial osteotomy, and articular cartilage surgery by a single surgeon (B.J.C.) were analyzed. Meniscal transplantation was performed using bone-in-slot techniques. Distal femoral and high tibial osteotomies were performed for valgus and varus malalignment, respectively. Microfracture, autologous chondrocyte implantation, and osteochondral autograft or allograft were performed for articular cartilage disease. Validated patient-reported and surgeonmeasured outcomes were collected. Preoperative and postoperative outcomes and medial versus lateral disease were compared using Student t tests. Results: Eighteen participants (mean age, 34 ± 7.8 years; symptomatic patients, 7.4 ± 5.6 years; 2.4 ± 1.0 surgical procedures before study enrollment; mean follow-up, 6.5 ± 3.2 years) were analyzed. Two thirds of participants had medial compartment pathologic conditions and one third had lateral compartment pathologic processes. At final follow-up, there were statistically significant clinically meaningful improvements in International Knee Documentation Committee (IKDC) subjective classification, Lysholm score, and 4 Knee Injury and Osteoarthritis Outcome Score (KOOS) subscores. Postoperative 12-item short form (SF-12) physical and mental component scores were not significantly different from preoperative scores. The Kellgren-Lawrence classification grade was 1.5 ± 1.1 at 2.5 ± 3.0 years after surgery. There was a significantly higher preoperative SF-12 physical composite score (PCS) in participants with lateral compartment pathologic conditions (v medial compartment conditions) (P =.011). Although there were 13 reoperations in 10 patients (55.5% reoperation rate), only one patient was converted to knee arthroplasty (5.6%) and one to revision cartilage surgery and meniscal transplantation (5.6% revision rate). The most common complication was arthrofibrosis (16.7%). Conclusions: Statistically significant and clinically meaningful improvements in validated patient-reported clinical outcome scores at long-term follow-up were observed in 18 participants undergoing combined meniscal transplantation, osteotomy, and articular cartilage surgery. Although there was a low rate of cartilage or meniscal revision (or both) and total knee arthroplasty, there was a high rate of reoperation. There was no significant difference in outcomes between participants with medial versus lateral pathologic conditions. Level of Evidence: Level IV, therapeutic case series.
