The treatment of massive rotator cuff tears remains controversial. There is lack of studies comparing patient-reported outcomes (PROM) of arthroscopic massive rotator cuff repairs (RCR) against large, medium and small RCRs. Our study aims to report the PROM for arthroscopic massive RCR versus non-massive RCR. Patients undergoing an arthroscopic RCR under a single surgeon over a 5-year period were included. Demographic data were recorded. Pre-operative Quick-DASH and Oxford Shoulder Score (OSS) were prospectively collected pre-operatively and at final review (mean of 18 months post-operatively). The scores were compared to a matched cohort of patients who had large, medium or small RCRs. A post-hoc power analysis confirmed 98% power was achieved. 82 patients were included in the study. 42 (51%) patients underwent massive RCR. The mean age of patients undergoing massive RCR was 59.7 and 55% (n=23) were female. 21% of massive RCRs had biceps augmentation. Quick-DASH improved significantly from a mean of 46.1 pre-operatively to 15.6 at final follow-up for massive RCRs (p<0.001). OSS improved significantly from a mean of 26.9 pre-operatively to 41.4 at final follow up for massive RCRs (p<0.001). There was no significant difference in the final Quick-DASH and OSS scores for massive and non-massive RCRs (p=0.35 and p=0.45 respectively). No revision surgery was required within the minimum one year follow up timescale. Arthroscopic massive rotator cuff repairs have no functional difference to non-massive rotator cuff repairs in the short term follow up period and should be considered in appropriate patient groups.
The aim of this study was to investigate the influence of age on the cost-effectiveness of arthroscopic rotator cuff repair. A total of 112 patients were prospectively monitored for two years after arthroscopic rotator cuff repair using the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), the Oxford Shoulder Score (OSS), and the EuroQol five-dimension questionnaire (EQ-5D). Complications and use of healthcare resources were recorded. The incremental cost-effectiveness ratio (ICER) was used to express the cost per quality-adjusted life-year (QALY). Propensity score-matching was used to compare those aged below and above 65 years of age. Satisfaction was determined using the Net Promoter Score (NPS). Linear regression was used to identify variables that influenced the outcome at two years postoperatively.Aims
Patients and Methods
There is clear evidence to support removal of the calcific deposit in patients with calcific tendonitis, however, there is conflicting evidence as to whether concomitant subacromial decompression (SAD) is of benefit to the patient. The aim of this study was to conduct a prospective double blind randomised control trial to assess the independent effect of SAD upon the functional outcome of arthroscopic management of calcific tendonitis. During a four year period 80 patients (power calculation was performed) were recruited to the study who presented with acute calcific tendonitis of the shoulder. Forty patients were randomised to have SAD and 40 were randomised not to have a SAD in combination with arthroscopic decompression of the calcific deposit. All surgery was performed by the senior author who was blinded to the functional assessment of the patients. There were 21 male and 59 female patients with a mean age of 48.9 (32 to 75) years. The pre-operative short form 12 physical component summary (PCS) was 39.8 and the mental component summary was 52.6, disability arm should and hand (DASH) score was 34.5, and the Constant score (CS) was 45.7. Both groups had a significant improvement in the PCS, DASH, CS at 6 weeks and at one year compared to their pre-operative scores (p<0.001). There were no significant differences demonstrated between the groups for any of the outcome measures assessed at 6 weeks or at one year. SAD should not be routinely performed as part of the arthroscopic management of acute calcific tendonitis.
We compared the outcome of arthroscopic repair of the rotator cuff in 32 diabetic patients with the outcome in 32 non-diabetic patients matched for age, gender, size of tear and comorbidities. The Constant-Murley score improved from a mean of 49.2 (24 to 80) pre-operatively to 60.8 (34 to 95) post-operatively (p = 0.0006) in the diabetic patients, and from 46.4 (23 to 90) pre-operatively to 65.2 (25 to 100) post-operatively (p = 0.0003) in the non-diabetic patients at six months. This was significantly greater (p = 0.0002) in non-diabetic patients (18.8) than in diabetics (11.6). There was no significant change in the mean mental component of the Short-Form 12, but the mean physical component increased from 35 to 41 in non-diabetics (p = 0.0001), and from 37 to 39 (p = 0.15) in diabetics. These trends were observed at one year. Patients with diabetes showed improvement of pain and function following arthroscopic rotator cuff repair in the short term, but less than their non-diabetic counterparts.
Autologous osteochondral cylinder transfer is a treatment option for small articular defects, especially those arising from trauma or osteochondritis dissecans. There are concerns about graft integration and the nature of tissue forming the cartilage-cartilage bridge. Chondrocyte viability at graft and recipient edges is thought to be an important determinant of quality of repair. The aim was to evaluate cell viability at the graft edge from ex vivo human femoral condyles, after harvest using conventional technique. With ethical approval and patient consent, fresh human tissue was obtained at total knee arthroplasty. Osteochondral plugs were harvested using the commercially available Acufex 4.5mm diameter mosaicplasty osteotome from regions of the lateral femoral condyle (anterior cut) that were macroscopically non-degenerate and microscopically non-fibrillated. Plugs were assessed for chondrocyte viability at the graft edge using confocal laser scanning microscopy (CLSM), fluorescent indicators and image analysis. The central portions of the plugs remained healthy, with >
99% cell viability (n=5). However, there was substantial marginal cell death, of thickness 382 ± 68.2 microm in the superficial zone (SZ). Demi-plugs were created by splitting the mosaicplasty explants with a fresh No. 11 scalpel blade. The margin of SZ cell death was 390.3 ± 18.8 microm at the curved edge of the Acufex, significantly (Mann-Whitney; P= 0.0286; n =4) greater than that at the scalpel cut (34.8 ± 3.2 microm). Findings were similar when the cartilage was breached but the bone left intact. In time-course experiments, the SZ marginal zone of cell death after Acufex harvest showed no increase over the time period 15 minutes to 2 hours. Mathematical modelling of the mosaicplasty surface shows that cell death of this magnitude results in a disturbing 33% of the superficial graft area being non-viable. In conclusion, mosaicplasty, though capable of transposing viable hyaline cartilage, is associated with an extensive margin of cell death that is likely to compromise lateral integration. There would appear to be considerable scope for improvement of osteochondral transplant techniques which may improve graft-recipient healing and clinical outcomes.
We describe a new technique for open reduction, bone grafting and fixation with a single Kirschner wire of unstable fractures of the distal radius. Of the 83 patients treated by this technique, most had regained volar tilt when seen at an average of 13 months after injury. Malunion was seen in 18 patients due either to poor placement of the graft and Kirschner wire or because of both volar and dorsal comminution. Assessment of hand and wrist function showed an average recovery of 63% of mass grip strength with an excellent return of specialised grip strength and range of movement. The advantages of this technique over closed methods include the ability to regain the volar tilt of the distal radius and to achieve reduction at any time before union of the fracture.
We performed transoesophageal echocardiography in 111 operations (110 patients) which included medullary reaming for fresh fractures of the femur and tibia, pathological lesions of the femur, and hemiarthroplasty of the hip. Embolic events of varying intensity were seen in 97 procedures and measured pulmonary responses correlated with the severity of embolic phenomena. Twenty-four out of the 25 severe embolic responses occurred while reaming pathological lesions or during cemented hemiarthroplasty of the hip and, overall, pathological lesions produced the most severe responses. Paradoxical embolisation occurred in four patients, all with pathological lesions of the femur (21%); two died. In 12 patients large coagulative masses became trapped in the heart. Extensive pulmonary thromboembolism with reamed bone and immature clot was found at post-mortem in two patients; there was severe systemic embolisation of fat and marrow in one who had a patent foramen ovale and widespread mild systemic fat embolisation in the other without associated foraminal defect. Sequential analysis of blood from the right atrium in five patients showed considerable activation of clotting cascades during reaming.
We performed an epidemiological analysis of 523 fractures treated in the Edinburgh Orthopaedic Trauma Unit over a three-year period using modern descriptive criteria. The fractures were defined in terms of their AO morphology and their degree of comminution, location and cause. Closed fractures were classified using the Tscherne grading system and open fractures according to the Gustilo classification. Further analysis of fractures caused by road-traffic accidents and football was carried out. The use of the AO classification allowed the common fracture patterns to be defined. Correlation of the classification systems showed an association between the AO morphological system and the Tscherne and Gustilo classifications. The relative rarity of severe tibial fractures is indicated and it is suggested that in smaller orthopaedic units the infrequency of these fractures has implications for training and the development of treatment protocols.
