Arthroscopic Procedure for Chronic Isolated Bucket-Handle Meniscal Tears

Meniscocapsular release technique to reduce chronic and challenging bucket-handle meniscus tear

Several surgical procedures for the repair of bucket handle meniscus tears have been reported in the literature. However, even the most skilled surgeon can find it difficult to treat chronic and locked lesions, which typically result in meniscectomies. Therefore, a repair method for bucket-handle meniscus tears that are chronic and locked is shown, along with a case series where this procedure was used. The technique consists of a release of the joint capsule attachment to the meniscal body, which increases the mobility of the meniscus and facilitates the reduction of the injury, allowing subsequent repair through a combination of both all-inside and inside-out repair techniques. The main objective of this technique is to reduce the need for meniscectomies in difficult cases of bucket-handle meniscus tears, protect the meniscal tissue, and slow the progression of osteoarthritis in the process.

Clinical and Radiologic Outcomes of Arthroscopic Rotator Cuff Repair in Medial Bursal-Side Fosbury Flop Tears Compared With Tendinous Avulsion Lesions

Purpose

To determine the clinical and radiologic outcomes after surgical repair of medial bursal-side Fosbury flop rotator cuff tears compared with traditional avulsion of tendinous attachments lesions.

Methods

A retrospective cohort study was performed. All patients who had undergone arthroscopic posterosuperior repair were recruited. Patients with previous shoulder rotator cuff surgery were excluded. Recruited patients were divided into 2 groups: one presenting Fosbury flop tears and the other presenting with standard avulsion lesions. Preoperative demographics such as age, gender, and arm dominance were recorded. Range of motion (ROM), visual analog scale (VAS) for pain and satisfaction, Constant score, Single Alpha-Numeric Evaluation score, and American Shoulder and Elbow Surgeons score were evaluated at 3 points in time: preoperatively, and at 6 months and minimum 1-year postoperatively. The healing of repaired cuffs was evaluated by ultrasound at 6 months.

Results

Two hundred thirty-six patients were recruited, with 27 (11.4%) Fosbury flop tears and 209 (88.6%) tendon avulsions. Although there was no significant difference in gender or arm dominance between the groups, Fosbury flop tears had significantly older patients (P < .05) with a mean age 61.6 years (standard deviation 9.0), compared with tendon avulsions with a mean age of 56.1 years (standard deviation 9.1). There was no significant difference in tendon retraction between the groups. Both groups demonstrated significant improvement in ROM, visual analog scale, American Shoulder and Elbow Surgeons, Single Alpha-Numeric Evaluation, and Constant score postoperatively at 6 months and minimum 1 year. The groups demonstrated no significant difference in the ROM and clinical scores. There was a nonsignificant difference in re-tear rate of 7.4% (2/27) in Fosbury flop tears compared with 2.8% (6/209) in tendon avulsions (P = .361).

Conclusions

Arthroscopic rotator cuff repair of medial bursal side Fosbury Flop rotator cuff tears results in favorable clinical and radiologic outcomes at 4 years after surgery. These outcomes are comparable with surgically repaired avulsion lesions, with an acceptable retear rate after arthroscopic repair.

Long-term clinical results of using a posteromedial all-inside and anteromedial inside-out approach to repair unstable or irreducible bucket-handle medial meniscal tears

BACKGROUND

In irreducible bucket-handle medial meniscal tears (BHMMTs), the displaced central fragment is rotated 180° or more, meaning reduction is impossible without derotation of the tear. In chronic cases, the rotated meniscus is deformed and degenerated; thus, the issue of reproducibility and repairability arises. This study presents the clinical outcomes of chronic irreducible and unstable locked BHMMTs. Radiological outcomes were also evaluated using magnetic resonance imaging (MRI).

METHODS

This is a retrospective study of 37 patients with 11 cases of irreducible BHMMT and 26 cases of reducible but unstable chronic BHMMT who underwent operations between 2011 and 2016. Posterior arthroscopy was performed after temporary meniscus fixation using a provisional needle fixation technique. After the posterior repair with vertical mattress sutures was completed using an all-inside technique, the classic outside-in technique was performed for the anterior third of the meniscus. The Lysholm, International Knee Documentation Committee (IKDC), and Tegner activity scores were obtained from all patients before surgery and at the latest follow-up. Radiological evaluations were performed using MRI before surgery and at 6 months postoperatively.

RESULTS

Between 2011 and 2016, a total of 37 consecutive patients with irreducible and chronic BHMMTs underwent surgery. The average postoperative follow-up was 7.2 ± 1.4 years (mean ± SD). Postoperative Lysholm (89.57 ± 2.7) and IKDC (87.22 ± 3.2) scores improved significantly at the last follow-up when compared with the pre-operative scores (38.44 ± 4.5 and 23.52 ± 7.8, respectively). According to the Tegner activity scale, patients' postoperative activity levels remained unchanged compared to preoperative levels at the last follow-up.

CONCLUSION

Posterior knee arthroscopy with the all-inside posterior suture and inside-out anteromedial suture technique presented in this study yielded excellent clinical outcomes when used to repair chronic irreducible or unstable BHMMTs.

Current concepts on meniscal repairs

The specific meniscus injury pattern were divided into many patterns. Nowadays, the meniscus root injury, radial tear meniscus, bucket handle tear meniscus and Ramp lesion were particularly focused on many way to manage and still controversial a lot of issues. Meniscus root tears (MRTs) and Ramp lesion are the most ignored, or misdiagnosed causes of chronic knee pain. Most patients delayed seeking treatment, consequently resulting in cartilage loss, and leading to the condition progressing to osteoarthritis knee. This has resulted in the rate of MR and Ramp repair increase significantly. The bucket handle meniscus tear trend to strong saving the anatomical meniscus and avoid to menisectomy. This article, on the other hand, will reveal you how to save and secure a nearly native meniscus fixation. In case of the radial meniscus, the partial meniscectomy is still used to treat this type of injury today, but it does not prevent degenerative changes from occurring, which can lead to unfavorable outcomes. Meniscal repair is a popular procedure for treating radial tears as an alternative to surgery. However, this pattern of meniscus tear can be difficult to repair and has a high failure rate, the arthroscopic meniscus repair techniques are published.
