The relationship between ACL reconstruction and meniscal repair: quality of life, sports return, and meniscal failure rate-2- to 12-year follow-up.

BACKGROUND: Few studies have approached in a long-term follow-up of meniscal repair at an amateur level, specially studying variables as a quality of life and failure rate. The purpose of this review is to study medium to long-term clinical results in patients at amateur sports patients, that have required meniscal sutures at our center, with or without ACL reconstruction. We evaluate the objective function of the knee, as well as patients' return to sports activities, quality of life, and the rate of failed repair and study of the possible reasons. METHODS: This was an observational retrospective study. Ninety-two patients who regularly perform amateur sports activities (Tegner 4 to 7) were assessed, with a minimum follow-up period of 2 years, divided into 2 groups: group 1, isolated meniscal suture (43 cases) and group 2, associated to ACL reconstruction (49 cases). Each patient made this test in 2019: Lysholm and Tegner (validated for Spanish) before a knee injury and after surgery, motivation to return to sports activity (Likert scale with 3 items: low, regular, or high), and quality of life through SD-12 test. RESULTS: High return to amateur sports rate (92%) was even higher in the isolated meniscal repair group in comparison to the group with associated ACL. We have not found statistically significant differences between sports return and age, gender, injured meniscus, chondral injuries, preoperative Tegner score, or motivation. No significant differences in physical or mental health fields between both groups. Meniscal repair failed in 12 patients (13%). Higher rate of failure in isolated bucket-handle tear injuries (p < 0.0062). No statistically significant association was found between the other variables studied. CONCLUSIONS: Good results with 92% of sports return, low rate of complications, and low retear rate, even lower when is associated with ACL reconstruction and in external meniscus repair, and high values at SF-12 between 2 groups.

The anterior limited approach of the elbow for the treatment of capitellum and trochlea fractures: Surgical technique and clinical experience in eight cases.

When a coronal fracture affects the capitellum and the trochlea, the Kocher lateral approach may be inadequate for the correct visualisation, reduction and fixation of the fracture. In such cases an associated medial elbow approach may be required, or a posterior transolecranon approach may be preferred. The anterior limited approach to the elbow (ALAE) could be a valid option when treating these types of fracture, as it does not involve the detachment of any muscle group or ligament, thereby facilitating the recovery process. We can also treat associated injuries such as fractures of the radial head or coronoid process with this approach. We describe the surgical technique and the functional outcome of eight patients with a mean of 66 years of age (range, 53-76) who where treated with open reduction and internal fixation for capitellar and trochlear fractures through the ALAE. Patient outcomes were assessed with physical and radiological evaluation, range-of-motion measurements with a follow-up from 24 to 60 months. Two different quality of life questionnaires were carried out: the EuroQol Five Dimensions Questionnaire (EQ-5D) and the patient-answered questionnnaire of the Liverpool Elbow Score patient (PAQ-LES). Four fractures involved the capitellum, one involved the capitellum with the lateral ridge of the trochlea, and three involved the capitellum and trochlea as separate fragments. The patients presented a favorable clinical evolution at a median of 33 months (range, 24-60), with an average of motion of 10-138°. Four patients presented a fracture of the head of the radius (Mason type 2) and 3 fractures of the coronoid (Bryan-Morrey Type 1) associated. All the patients presented radiological consolidation without signs of osteonecrosis, being the average EQ-5D 0.857 (range, 0.36-1.0) and the PAQ-LES of 35 (range 17 to 36). Patients with isolated capitellar fractures had better results than those with trochlear involvement. The presence of associated fractures does not seem to worsen the results. We believe that the ALAE is a technical option to consider for the open surgical treatment of a capitellar fracture with or without involvement of the trochlea. LEVEL OF EVIDENCEIS: Therapeutic Level III.

A biomechanical comparison of the modified Bunnell pullout and Teo intraosseous suture techniques for attachment of tendon to bone.

We compared the biomechanical properties of the Teo intraosseous suture technique with the modified Bunnell pullout technique in a cadaver model after a tendon to bone repair. Thirty-six fresh-frozen cadaveric fingers were assigned randomly to three groups (Teo, Bunnell and control groups). They were loaded cyclically from 2 to 15 N at 25 mm/min, for 500 cycles. Gap formation at the repair site was assessed every 100 cycles and then specimens were tested to failure. The Teo group had an approximately 30% smaller gap every 100 cycles and needed 30% more energy to obtain a 2 mm gap than the modified Bunnell group. Displacement after 500 cyclic loads was significantly lower in the Teo group than in the Bunnell group. For the failure of the Teo suture, it was necessary to apply 31% more load than the Bunnell technique.
