Adhesive capsulitis is a common condition causing painful limitation of shoulder movements. Hydrodistension is one of the techniques, is well recognised and has shown good outcomes. However, the results of hydro distension release in secondary adhesive capsulitis are not clear. This is a retrospective study on patients undergoing hydro distension release. Patients who had any surgical intervention were classed as secondary whilst the rest were included in the primary group. The hydro distension is a standard technique where in the senior author locates the gleno humeral joint using radio opaque dye, followed by injection of 20 mls 0.5% L-bupivacaine and 80 mg of Triamcinolone, this is followed by use of 60 mls saline to perform the hydro distension.Introduction
Patients and Methods
To see if minor upper limb surgery procedures like CTR, Trigger release, Joint injections are safe for a remote telephonic review by specialist nurse. This arrangement was to help maintain our current agreed departmental New to Follow up ratio of 1:1.56 and also to improve access to specialist clinics. This was a prospective study. Patients undergoing minor procedures were informed about the remote follow up arrangements when placed on waiting list and on the day of surgery. Patients were assured access to clinic up to 3 months after procedure. A specialist nurse undertook a telephone consultation at 2 and 6 weeks using a proforma provided by the Consultant.Aim
Methods
The MHRA guidelines for metal on metal (MOM) suggest cobalt and chromium levels of more than 7ppb as potential for soft tissue reaction. However, in some patients soft tissue reaction is seen even in the presence of normal serum metal ions levels. A prospective review of all patients who had metal-on-metal hip arthroplasty was done. Patients who had both serum metal ion levels and MARS MRI scan were included in this study.Introduction
Methods
The Bankart lesion is the most common form of labro-ligamentous injury in patients with traumatic dislocations of the shoulder. Various methods have been described each with its own advantages and disadvantages. We describe 5-year results of arthroscopic Bankart repair using knotless anchors. There were 38 patients, with involvement of the dominant arm in 28 patients. Recurrent dislocation was the most common indication in 21 patients, followed by first dislocation in 9 patients and second dislocation in 8 patients. All patients were done under general anesthesia and regional block in beach-chair position. Standard portals were used and repair done using 2.9 mm pushlock knotless anchors (Arthrex®). Patients had sling for 4 weeks and followed by a strict physiotherapy rehab protocol. Patients were followed up at 6 weeks and 3 monthly thereafter.Introduction
Patients and Methods
Revision surgery for a failed metal on metal (MoM) hip arthroplasty is often unpredictable and challenging due to associated massive soft tissue and bony lesions. We present the analysis and early outcomes of revision surgery in failed MoM hip arthroplasties at our institution. We have retrospectively analysed the findings and outcomes of revision surgery in 61 failed MoM hip arthroplasties performed between 2009 and 2014. These patients were identified in the special MoM hip surveillance pathway. All these patients underwent clinical assessment and relevant investigations. Intra-operative and histopathological findings were analysed.Background
Methods
A prospective study was done to assess the outcome of MPFL reconstruction for patellar instability using quadriceps graft. MPFL reconstruction was done using superficial strip of quadriceps by an anteromedial incision and attached close to medial epicondyle of femur. There were 15 knees in thirteen patients with a mean age of 23.4 years. All patients had MPFL reconstruction and 5 had tibial tuberosity transfers. With a mean follow-up of 39.4 (12–57) months, the mean pre-op Kujala scores improved from 47.8 to 87.2. The mean Lysholm scores improved from 54.2 to 86.8. None of the patients had patella re-dislocations. MPFL reconstruction with quadriceps graft appears to be effective producing good results in patients with patellar instability.
Total knee replacement (TKR) can be associated with significant post-operative blood loss requiring blood transfusion and haematinics. With increase in the use of navigation for total knee replacement, it is anticipated the blood loss may be lower as the medullary cavity is not breached. Hence, a prospective study was performed to compare the blood loss and the transfusion rates between patients with navigated and conventional total knee replacement. Between September 2006 and December 2009, nearly 100 patients underwent total knee replacement by a single surgeon. Patients who underwent revision total knee replacement and complex primary total knee replacement were excluded. There were 73 patients with an average age of 70.3 (47-91) years. There were 37 males and 36 females with an average BMI of 30. Thirty eight patients underwent navigated TKR and 35 patients conventional TKR. Left knee was replaced in 29 patients, right knee in 40 patients and 4 patients underwent non-simultaneous bilateral total knee replacements. Cruciate retaining prosthesis was used in 17 patients and cruciate substituting prosthesis in 56 patients. Patella was not replaced in any patient. The average pre-operative haemoglobin was 13.26 (8.7-18.4) g/dl in the navigated group and 13.47 (9.6-15.8) g/dl in the conventional group. The average tourniquet time was 110(90-150) minutes in the navigated group and 96.7(60-145) minutes in the conventional group. Seven patients in the navigated group and 3 patients in the conventional group did not have documentation of the tourniquet time. The average post-operative haemoglobin in the navigated group was 10.34 (7.5-14.8) g/dl and 10.03 (7.5-12.2) g/dl in the conventional group. Six patients each in the navigated group and conventional group required blood transfusion. Six patients in the navigated group and 8 patients in the conventional group were started on haematinics. This study does not show any significant difference in the blood loss as estimated by the average drop in the post-operative haemoglobin between navigated and conventional total knee replacement. There was also no difference in the rates of blood transfusion between both the groups. However the average operative time was marginally higher in the navigated group than the conventional group.
To analyse the intra-operative variation in mechanical axes of the lower limb at various stages during navigated total knee replacement. A prospective study was performed to analyse the intra-operative variation in the mechanical axes of the lower limb during navigated total knee replacement. All consecutive patients who underwent navigated total knee replacement were included and patients with inadequate data were excluded from the study. The intra-operative initial, trial and the final mechanical hip-knee-ankle axes were recorded from the navigation system. The differences between these axes were calculated and analysed. There were forty patients, of which 24 were females and 16 males with the age ranging from 37-89 (average 68.4) years. The right knee was replaced in 27 and the left knee in 13 patients. The average initial mechanical axes alignment was 0.03° valgus (3° varus to 3° valgus), trial alignment 0.64° varus (3° varus to 1.5° valgus) and final alignment 0.25° varus (4° varus to 4° valgus). Average deviation from initial to trial axes was 0.97°, trial to final axes was 0.74° and initial to final axes was 1.08°. The correlation co-efficient between the initial and the trial axes was 0.25, trial and final axes was 0.43 & initial and final axes was 0.09. This study highlights a significant variation in mechanical axes between the different stages of navigated total knee replacement. The potential sources of intra-operative errors causing these changes could be soft tissue imbalance, variations in implant placement and possible tracker micro motion. Execution of bony cuts in near normal neutral alignment does not guarantee achievement of near normal final alignment. We advocate surgeons to be vigilant to avoid potential malalignment during navigated total knee replacement.
