  Background

Tears of the medial meniscus posterior horn (MMPH) are frequently found in knees with deficient anterior cruciate ligaments (ACLs). There are few studies that have evaluated healing of the menisci and the factors associated with healing.

Hypothesis

The repaired menisci would show good healing in the knees with reconstructed ACLs, and the healing capacity of the menisci would differ according to the size, type, and location of the tear as well as the age and gender.

Study Design

Case series; Level of evidence, 4.

Methods

From August 1997 to February 2007, 311 knees underwent MMPH repair using either a modified all-inside or inside-out technique with concomitant ACL reconstruction. Among these patients, a second-look arthroscopy was performed at a mean of 37.7 months postoperatively (range, 12–128 months) in 140 patients. Clinical parameters and outcomes were evaluated. The repaired menisci were divided into complete, incomplete, and failure-to-heal groups. The factors associated with meniscal healing were statistically assessed.

Results

Among 140 patients, 118 (84.3%) showed complete healing, 17 (12.1%) had incomplete healing, and 5 (3.6%) failed to heal. The clinical success rate was 96.4% (135/140) because patients in the incomplete group showed no clinical symptoms associated with meniscal tears. Healing was associated with the tear location (P <.001) and type of tear (P =.0237) on the univariate analysis and the location (P =.0401) only on the multivariate analysis.

Conclusion

Repaired MMPH tears in knees with reconstructed ACLs healed without complications and had satisfactory clinical results. The tear location and type were factors associated with healing on the univariate analysis and location only on the multivariate analysis.

Background: During rotator cuff repair, biceps tendon lesions are frequently encountered. However, there is still controversy about optimal treatment for these lesions.

Purpose: To compare the results of tenotomy and suture anchor tenodesis prospectively.

Study Design: Cohort study; Level of evidence, 2.

Methods: From January 2006 to June 2007, 90 patients (age, >55 years) with a rotator cuff tear and biceps tendon lesion (tear more than 30%, subluxation or dislocation, or degenerative superior labrum anterior to posterior lesion type II) were evaluated prospectively. The first 45 patients treated consecutively underwent biceps tenodesis, and the next 45 underwent biceps tenotomy. Postoperatively, patient evaluations were conducted with a focus on (1) "Popeye" deformity, (2) arm cramping pain, and (3) elbow flexion powers (measured with a hand dynamometer). Overall shoulder function was assessed with the American Shoulder and Elbow Surgeons (ASES) score and the Constant score.

Results: At final follow-up, 43 in the tenodesis and 41 in the tenotomy groups were available for evaluation. There was no difference between groups in demographic data such as age, sex, dominant arm, and the time from symptom to surgery and in preoperative ASES score, Constant score, and rotator cuff tear size. A Popeye deformity occurred in 4 (9%) in the tenodesis group and in 11 (27%) in the tenotomy group (P = .0360). Mild cramping pain was observed in 2 in the tenodesis group and 4 in the tenotomy group (P = .4274). Mean elbow flexor power ratio (vs the contralateral side) showed no difference between the 2 groups, with mean values of 0.92 ± 0.15 (tenodesis) and 0.94 ± 0.19 (tenotomy) (P = .7475). The ASES and Constant scores were improved from 38.9 ± 14.2 and 52.1 ± 21.3 to 84.7 ± 13.6 and 82.9 ± 13.5 in the tenodesis group (P < .0001) and from 35.2 ± 10.5 and 48.1 ± 21.3 to 79.6 ± 15.8 and 78.3 ± 14.1 in the tenotomy group (P < .0001), respectively.

Conclusion: Suture anchor tenodesis of the long head of the biceps tendon appears to lead to less Popeye deformity than tenotomy. No other clinical variables showed a difference between the 2 modalities.
