What are the Factors that Impact the Outcomes of Arthroscopic Rotator Cuff Repair?

BACKGROUND: The cuff is a complex structure with many factors affecting it. How much it is affected after repair is still being investigated. AIM: The aim of this study was to analyze the functional results of individuals who received arthroscopic rotator cuff repair and assess the various factors that could impact these outcomes. METHODS: The study included 57 patients with a mean age of 58.8 years (range: 39-71) who underwent arthroscopic rotator cuff repair between 2013 and 2020, with a minimum of 6 months after the operation. Functional and clinical outcomes of the patients were evaluated using preoperative and postoperative scores (QDASH, ASES, and VAS). The study also analyzed how demographic factors, type and duration of the tear, comorbidities such as diabetes mellitus (DM) and hypertension (HT), and other pathologies may have affected the patients' scores. RESULTS: The effect of the operation on the scores in rotator cuff tears was highly significant (P < 0.05). Age, gender, tear size, fatty degeneration, anchor configuration, comorbidities, and additional procedures presented variable values on postoperative scores, but were not statistically significant. The effect of DM and HT on VAS scores was statistically significant (P < 0.05). CONCLUSION: The results of rotator cuff repair appear to be influenced by several factors, including the sex of the patient, type and duration of tear, comorbidities, and surgical procedures used. Although these factors had an effect on the scores, they were not statistically significant.

Review of Anterior Submuscular Transposition of Ulnar Nerve for Cubital Tunnel Syndrome.

OBJECTIVE: In this study, we report the results of patients who underwent ulnar nerve submuscular anterior transposition surgery due to cubital tunnel syndrome. METHODS: Data of 46 patients who underwent anterior submuscular transposition surgery due to cubital tunnel syndrome between January 2010 and December 2014 were retrospectively reviewed. Twenty-seven patients with preoperative and postoperative complete medical records available and who had completed at least 24 months follow-up were included in the study. RESULTS: According to preoperative McGovan staging system, 1 patient was classified as stage 1, 8 were stage 2A, 3 were stage 2B, and 15 were stage 3. The mean follow-up time was 61.4 (35-88) months. The mean DASH score of the patients was calculated as 19 (0-81.81). Mayo elbow performance score was excellent in 13 patients, good in 7, fair in 6, and poor in 1. CONCLUSION: Anterior submuscular transposition of ulnar nerve had resolved symptoms 89% of our patients. The technique is a successful method with a low recurrence and complication rate.

Mid-term Results of Two-Stage Tendon Reconstruction of Zone II Flexor Tendon Injuries.

BACKGROUND: Secondary repair of flexor tendon injuries remains a challenging procedure for hand surgeons. Usually, secondary reconstruction should be performed by a staged approach. Two-stage surgical reconstruction of the flexor tendons by the Hunter technique is the salvage option in case of a severely damaged fibro-osseous canal or neglected flexor tendon injury. AIMS: We report the results of staged flexor tendon reconstruction in 10 patients (10 fingers) with neglected or failed primary repair of flexor tendon injuries in zone II. MATERIALS AND METHODS: Between 2012-2016, patients who underwent two-stage tendon reconstruction due to flexor digitorum profundus (FDP) sectioning or tearing in zone II with destruction of flexor pulleys and extensive scarring in the flexor tendon bed were included in the study. RESULTS: Ten patients included to study with a mean follow-up of 34 months (range 12-70 months) and the results were assessed by clinical examination and questionnaire. According to the Strickland score, one (20%) of the results were excellent, five (50%) were good, two (20%) were fair and two (20%) were poor. After the second stage, good to excellent results were achieved in 60% of patients, one patient needed graft tenolysis. These results were similar to the subjective scores given by the patients, four of whom complained of functional problems in daily life at follow-up. There was no complication after the first stage. But after the second stage, there was one bowstringing and one adhesion that require tenolysis. CONCLUSIONS: Hunter technique is still the reference procedure for the reconstruction of flexor tendons. The results of our study showed that two-stage tendon reconstruction which is applied in patients with tendon sheath disruption as a result of acute or delayed tendon injuries which are not possible for primary repair is reliable and satisfactory.

Mid term results of radial metaphyseal core decompression on Kienböck's disease.

OBJECTIVE: Kienböck's disease is a commonly seen posttraumatic avascular necrosis characterized by avascular necrosis of the lunate bone of the wrist which involves the dominant hand. In our study, we aimed to present midterm outcomes of 12 cases treated with radial metaphyseal core decompression. PATIENTS AND METHODS: In our clinic, 12 patients who applied to our outpatient clinic with intractable pain despite at least six weeks of conservative treatment were previously diagnosed and evaluated as Kienböck's disease between the years 2006 and 2014. Patients at early stage received radial metaphyseal core decompression. RESULTS: The patients were evaluated as postoperative grip strength, flexion-extension gap, ulnar-radial deviation gap, VAS, Quick DASH and MAYO wrist scoring and patient satisfaction. CONCLUSIONS: We determined that interventions performed for Kienböck's disease cannot halt radiological progression. We are of the opinion that radial metaphyseal core decompression, aiming at increasing blood perfusion, improve early diagnosis and treatment of Kienböck's disease, increasing the patient satisfaction.

Transient bone loss of distal radius and ulna following clean-cut tendon injuries, repair and passive mobilisation.

The aim of this study was to investigate whether there is any significant bone loss of the ulna and radius following acute tendon-artery-nerve clean-cut injuries at the wrist level which were repaired and rehabilitated by early passive mobilisation. Fifty-eight patients who underwent such operation were enrolled in this study. Patients in Group I (n=28) had primary tendon repairs alone, in Group II (n=15) primary tendon and nerve repairs and in Group III (n=15) primary tendon, nerve and artery repairs. Bone mineral density (BMD) measurements of the ulna and radius were obtained during the first week, the sixth week, the third month and the 12th month after operation. The results demonstrated that BMD decrease in the ulna was more common than in the radius. When compared with the first week BMD measurements, the highest reduction was seen in the sixth week in Group I and during the third month, when bone loss of both the radius and ulna was considerable in Group II. The bone loss in all groups and subgroups were found to have recovered at the 12th month measurements, except in the distal region of the ulna in Group I. This study suggests that passive immobilisation is deleterious in respect of demineralisation of the forearm bones.

Comparison of three conservative treatment protocols in carpal tunnel syndrome.

The aim of this study was to investigate and compare the therapeutic effect of three different combinations in the conservative treatment of carpal tunnel syndrome (CTS) by means of clinical and electrophysiological studies. The combinations included tendon- and nerve-gliding exercises in combination with splinting, ultrasound treatment in combination with splinting and the combination of ultrasound, splinting, tendon- and nerve-gliding exercises. A total 28 female patients (56 wrists) with clinical and electrophysiologic evidence of bilateral CTS were studied. In all patient groups, the treatment combinations were significantly effective immediately and 8 weeks after the treatment. The results of the long-term patient satisfaction questionnaire revealed that symptomatic improvement is more prominent in the group treated with splinting, exercise and ultrasound therapy combination. Our results suggest that a combination of splinting, exercise and ultrasound therapy is a preferable and an efficacious conservative type of treatment in CTS.

Effect of resveratrol in experimental osteoarthritis in rabbits.

OBJECTIVE: Resveratrol (trans-3,4',5-trihydroxystilbene) is a phytoalexin found in high concentration in the skins of grapes and red wines which has been shown to have antiinflammatory, anticancerogen and antioxidant properties. Resveratrol is a potent and specific inhibitor of nuclear factor kappa B (NF-kappaB). Resveratrol also inhibits COX-2 gene expression and enzyme activity. We aimed to determine the in vivo effects of intra-articular injections of resveratrol on cartilage and synovium in an experimental osteoarthritis (OA) model in rabbits. METHODS: As OA model, rabbits underwent unilateral anterior cruciate ligament transection (ACLT). Five weeks after test group was injected with 10 microMol/kg resveratrol in dimethylsulphoxide (DMSO) in the knees once daily for two weeks and as the control group at the same time DMSO was injected into the knees. All rabbits were killed one week after the last injection. Cartilage tissue and synovium were evaluated with a histological scoring system. RESULTS: Histological evaluation of cartilage tissue by H&E staining revealed a significantly reduced average cartilage tissue destruction score of 1.7 in the resveratrol group versus 2.8 in the control group (p = 0.016). Loss of matrix proteoglycan content in cartilage was also much lower, as determined by safranin O staining. Scores of synovial inflammation didn't show difference between groups (1.3 vs 2.2; p = 0.057). CONCLUSION: A characteristic parameter in arthritis is the progressive loss of articular cartilage. This study suggests that intraarticular injections of resveratrol starting at the onset of disease may protect cartilage against the development of experimentally induced OA.

Anterior sacroiliac fusion: a new video-assisted endoscopic technique.

We present a case of sacroiliac fusion performed for an intraarticular osteochondroma of the sacroiliac joint, which was the cause of severe pain and disability. Excision of the lesion and sacroiliac fusion were successfully performed by utilizing minimally invasive surgical techniques. Although the application of this technique requires a dedicated and highly experienced team, the encouraging result of our first case, with minimal morbidity and disability due to the operation, induces us to recommend this technique in sacroiliac fusion, especially when fusion is combined with additional procedures such as drainage, biopsy, or excision.
