Abstract

Combined knee injuries of the anterior cruciate ligament (ACL), medial collateral ligament (MCL), and medial meniscus were called “the unhappy triad” in the past. With recent advances in diagnostic technology, combined ACL, MCL, and lateral meniscus injuries are now known to be the predominant triad. We examined and verified the treatment outcomes of the triad of combined knee injuries from both patient-based subjective evaluation and objective assessments. We studied 49 knees (49 patients) with combined injuries of the ACL, MCL, and lateral meniscus. These cases were divided into those who underwent simultaneous ACL and MCL reconstruction (group A, 18 cases) and those who underwent ACL reconstruction only because MCL injury could be treated conservatively (group B, 31 cases). Clinical evaluation was conducted preoperative and 24 months or longer after surgery. The methods included patient-reported outcomes using Short Form-36, and conventional assessments using Lysholm's score, visual analogue scale (VAS), and quantitative measurement of knee instability using Telos SE. Compared with presurgical scores, the postsurgical Short Form-36 scores showed improvements in all eight subscales, all reaching the national standard values. Significant improvements were observed in the five subscales in group A and seven subscales in group B. Furthermore, significant improvements in Lysholm's score, VAS pain score, and quantitative knee instability were achieved in both groups. This study demonstrated successful clinical outcomes in patients with a triad of knee injuries who were treated with lateral meniscus repair or partial meniscectomy and either combined MCL/ACL reconstruction or ACL reconstruction alone.
