Introduction: Harvesting peroneus longus for ACL reconstruction is thought to create ankle instability which could add to postural instability from an ACL injury. This apprehension prevents its use as a graft of primary choice for many surgeons. To date, there is no evidence available describing changes in postural control after its use in ACL reconstruction. The purpose of the study was to analyse the changes in postural control in the form of static and dynamic body balance after ACL reconstruction with Peroneus Longus Tendon Graft and compare it with the unaffected limb at different time intervals.

Materials and methods: Thirty-one participants with ACL injury were selected and subjected to an assessment of static and dynamic balance before and after ACL reconstruction using the HUMAC balance system. Outcome measures for Centre of Pressure (COP) assessment were average velocity, path length, stability score, and time on target. Comparison of scores was done pre-operatively as well as at three- and six-months post-reconstruction with Peroneus longus tendon graft.

Results: Static balance of the affected limb showed significant improvement with a decrease in average velocity (F=4.522, p=0.026), path length (F=4.592: p=0.024) and improvement of stability score (F=8.283, p=0.001). Dynamic balance measured by the time on the target variable also showed significant improvement at six-month follow-up (F=10.497: p=0.000). There was no significant difference between the affected and non-affected limb when compared at the different time intervals.

Conclusion: The static and dynamic balance, which is impaired after ACL injury, improves with ACL reconstruction with PLT autologous graft. Hence PLTG can be safely used as a graft for ACL reconstruction without affecting postural control and body balance.

Introduction: Proximal tibial plateau fractures are one of the major problems in orthopaedic surgery and are associated with high complication rates. Intra-articular proximal tibia plateau fractures represent approximately 1% of fractures in adults. Various modalities of proximal tibial plateau fracture management have been considered, ranging from simple external fixators in impending compartment syndrome to periarticular proximal tibia plates and inter-locking nails with poller screws. Purpose of this study is to determine clinical outcomes of proximal tibial plateau fractures treated with plate.

Materials and methods: We did this study of proximal tibial plateau fracture according to Schatzker's classification treated with proximal tibial periarticular plates in 53 patients prospectively admitted at the author's institute from June 2018 to May 2020 with follow-up period of 6 months.

Results: In our study, the average knee score was 89.30 (ranging from 79 to 93) and functional knee score was 97.92 (ranging from 75 to 100). Fifty-one (51) patients (96.23%) showed excellent results and 2 patients (3.77%) showed good results according to Knee Society Score, which suggest that internal fixation of proximal tibia plateau fracture with plating provides better results. Out of 53 patients, 9 patients had post-operative complications. Average radiological union was seen at 14 weeks.

Conclusion: Locking compression plate in proximal tibia plateau fractures act as a good biological fixation provide stable fixation, articular reduction and limb alignment even in difficult fracture situations. Fixation of proximal tibia plateau fractures with plate gives excellent to good knee society score, with satisfactory functional and radiological outcome.

Introduction: Total knee arthroplasty (TKA) is a common operation and is becoming more common due to population aging and increasing BMI. TKA provides excellent improvement in quality of life but carries risk of arterial complications in the perioperative period. This systematic review aims to provide a greater understanding of the incidence of such complications, and time taken to diagnose arterial injury.

Materials and methods: PubMed, Medline, Ovid SP and EMBASE databases were searched with the following MeSH keywords: 'complication', 'vascular injury', 'ischaemia', 'spasm', 'thrombosis', 'pseudoaneurysm', 'transection', 'pulse', 'ABPI OR ABI', 'Doppler', 'amputation'. All arterial vascular events in the perioperative state of the total knee replacement were included. Records were independently screened by two reviewers, and data was extracted according to a pre-determined proforma. Overall incidence and time to diagnosis was calculated for complications. Systematic review registration PROSPERO: CRD42018086643. No funding was received.

Results: Twelve studies were selected for inclusion. A total of 3325 cases of arterial complications were recorded across all studies, and were divided into three categories, pseudoaneurysms (0.06%); ischaemia and thrombosis (0.17%); haemorrhage and arterial transections (0.07%). Time taken to reach the diagnosis for each complication was longest in the ischaemia and thrombosis group (6.8 days), followed by pseudoaneurysm (3.5 days) and haemorrhage and transections (3.0 days).

Conclusion: TKA post-operative vascular complications are rare, but when they do occur they lead to limb and life threatening complications. This should be discussed with patients during the consent process. Current times to diagnosis represent missed opportunities to recognise arterial injury and facilitate rapid treatment of the complication. A very low threshold for seeking specialist input should be adopted, and any concern for vascular injury, such as unexplained perioperative bleeding, absent lower limb pulses in the post-operative period or unexplained severe pain should warrant immediate review by a vascular surgeon, and in centres where this is not possible, immediate blue-light transfer to the closest vascular centre.

Introduction: Isolated meniscal repair has been suggested as one of the contributing factors in unhealed meniscal repair. The purpose of this study was to compare the healing rate between isolated meniscal repair and meniscal repair with concomitant anterior cruciate ligament reconstruction (ACLR) using a standardised assessment method after propensity score matching.

Materials and methods: Accuracy of the Crues' grading system for meniscal healing was validated using second-look arthroscopy as the reference standard in 17 patients. Propensity score matching (one-to-one) was performed between 26 patients who underwent isolated meniscal repair and 98 patients who underwent meniscal repair with concomitant ACLR. Patients were matched for sex, age, side and zone of the meniscal repair, and number of sutures. Healing rates at one year which were evaluated with magnetic resonance imaging (MRI) were compared between the two groups.

Results: The sensitivity and specificity of the Crues' grading system on multiple plane MRI for meniscal healing were 100% and 83.3%, respectively. Both the isolated meniscal repair group and the meniscal repair with concomitant ACLR group included 21 patients after propensity score matching. Baseline characteristics did not differ significantly between the two groups. The healing rate was significantly lower in the isolated meniscal repairs group (14.3%) than in the meniscal repair concomitant with ACLR group (47.6%, P=0.04).

Conclusion: The healing rate for isolated meniscal repair using a standardised MRI assessment method was inferior to that of meniscal repair with concomitant ACLR after propensity score matching.

Introduction: Spinal osteochondroma is rare. The purpose of this study is to examine the clinical characteristics and surgical treatment outcomes of 11 patients with spinal osteochondroma.

Materials and methods: The study included 11 patients with spinal osteochondroma. In these patients, we examined the onset level, onset site, initial symptoms, surgical procedure, outcomes and complications.

Results: Of the 11 patients, 9 presented with solitary tumours, and 2 had multiple. The mean post-operative observation period was six years and two months. The onset level was the cervical spine in eight patients, thoracic in two, and lumbar in one. The most common onset site was the posterior elements. The initial presentation was myelopathy in seven patients, radiculopathy in two, neck pain in one and feeling of mass in one. All patients underwent excision of the tumour, and depending on the tumour onset site, additional posterior or anterior decompression with or without fusion was performed. There was no recurrence in all patients. Intra-operative complications included dura tear and oesophageal injury in one patient with cervical onset, while post-operative complications included C5 palsy in one patient.

Conclusions: In this study, surgical excision for osteochondroma of the spine were excellent with no recurrence of the tumour.

Introduction: ACL rupture is the most common type of knee injury. The All-inside ACL reconstruction procedure features some distinguished components including closed-socket tunnels with less bone expulsion, double suspensory fixation, and smaller incisions. We aimed to compare the outcomes between the All-inside Single-bundle and the Double-bundle ACL reconstruction techniques.

Materials and methods: This study was a retrospective study which analysed the patient-reported and the clinical outcomes on patients who underwent ACL reconstruction between January and December 2020 at Dr Kariadi General Hospital Semarang, Indonesia. We compared the patient-reported and the clinical outcomes at 6- and 12-month follow-ups between the All-inside Single-bundle and the Double-bundle groups. The patient-reported outcomes were determined using the IKDC and Tegner-Lysholm scores while the clinical outcomes included the measurement of Thigh Circumference, Single Hop test, Anterior Drawer test, Lachman test, Range of motion, and the patient's level of return to sport.

Results: A total of 24 subjects were divided into two groups, namely the All-inside Single-bundle and the Double-bundle groups, consisting of 12 subjects in each group. Most of the subjects were male in both groups, including 9 (75%) subjects in the All-inside Single-bundle group, and 11 (91.67%) subjects in the Double-bundle group. The mean age of the subjects were 25.75±7.57 years old in the All-inside Single-bundle group, and 24.5±6.87 years old in the Double-bundle group. In terms of the side of the knee that suffered the most injuries in both groups were the right knees. The result of the patient-reported outcomes using IKDC and Tegner-Lysholm scores showed no statistically significant differences in both groups at 6- and 12-month follow-ups (p=0.864; p=0.293 and p=0.589; p=0.233, respectively). The results of clinical assessments at 6- and 12-month follow-ups also showed no statistically significant differences in both groups.

Conclusion: Our study showed no significant differences in the patient-reported and the clinical outcomes between the All-inside Single-bundle and the Double-bundle ACL reconstruction techniques at 6- and 12-month follow-ups.

Introduction: This study aimed to determine on-admission and perioperative factors predicting six-month mortality and functional recovery in Vietnamese patients with hip fracture.

Materials and methods: Between April 2020 and July 2021, 118 patients participated in this prospective study. Patients' data were collected from medical records. Harris hip score (HHS) was used to evaluate the functional recovery six months after fractures. The obtained data were analysed using a univariate and multivariate model.

Results: The mean age of the participants was 79.5±9.4 years and 68.6% of the patients were female. The six-month mortality rate was 5.9% and independently associated with age (odds ratio (OR): 3.512, 95% confidence interval (CI) 1.538 - 8.019; P<0.001, patients aged >80 years vs those aged ≤80 years) and hypoproteinemia (OR: 2.859, 95% CI: 1.001 - 8.166, P=0.049). Among 111 survivors there were 66 (59.5%) of patients with a good functional recovery. Patients aged >80 years had a higher risk of poor functional outcome (OR: 3.167, 95% CI: 1.386 - 7.235, P: 0.006) compared to those aged ≤ 80 years. No significant correlations between other clinical (gender, body mass index, comorbidities, type of fractures or surgery, time until surgery) or laboratory parameters (anaemia, hyperglycemia, marked elevation of C reactive protein level, electrolyte abnormalities, elevated urea) and mortality or functional outcome were found.

Conclusion: Advanced age is the most important factor affecting both mortality and functional outcome while hypoproteinemia is associated with a higher risk of mortality in elderly patients with hip fractures.

Introduction: Despite several techniques for corrective osteotomy in congenital radioulnar synostosis (CRUS) the published literature lacks a guide for radiographic planning and rationale for the site and level of the osteotomy. The primary objective of this study is to report a technique of radiographically controlled corrective osteotomy using the axis of rotation of the forearm in CRUS.

Materials and methods: Children with CRUS underwent corrective osteotomy based on radiographic planning; the extent of rotational correction and functional outcomes were assessed at a mean of 27 months after the operation.

Results: Seven forearms in six children of an average of 6.25 years were assessed for correction and functional outcomes. The average pre-operative pronation deformity was 71.5°. The average correction achieved was 64°. At follow-up, there were five excellent and two good functional outcomes. All children could perform daily tasks besides eating with hand and personal hygiene.

Conclusion: Radiographic determination of the osteotomy sites by the method described is effective, consistent, and reproducible in achieving optimal functional outcomes in congenital radioulnar synostosis.

Introduction: The awareness of under-representation of female surgeons in orthopaedics has been increasing in this decade. We aim to investigate the reasons why female surgeons chose orthopaedic, the barriers that possibly hinder female surgeons into orthopaedics and analyse the obstacles that they encountered in their career in Malaysian context.

Materials and methods: A total of 101 registered female orthopaedic surgeons registered with the Malaysian Medical Council, during the period 1980 to 2020, were contacted for a cross-sectional survey, consisting of thirty-four questions on their experience in the orthopaedic career. Eighty-two responses were received (81.2%). Questions in this survey consisted of four sections: (1) demographic details, (2) current clinical practice environment, (3) orthopaedics training experience, and (4) career experience.

Results: A total of 49% of respondents had subspeciality training, highest in paediatric orthopaedic (30%). Enjoyment of manual tasks (64.6%) and professional satisfaction (64.6%) were the top reasons for choosing orthopaedic as a career. Primary barriers to orthopaedic were physical strength required (56.0%) and public gender bias (52.4%). Twenty-eight percent reported gender discrimination in career opportunities while 60% reported similar in daily work. Thirty-three percent reported verbal and 11% physical sexual harassment in their career. Forty-four percent of respondents reported benefits as female orthopaedic surgeon in their work.

Conclusion: The reasons for Malaysian female orthopaedic surgeons to choose orthopaedic as their career and the barriers perceived to hinder other females from choosing orthopaedics were similar to reports worldwide with no exception to gender discrimination and sexual harassment. The support given by male colleagues to married female surgeons marked a unique phenomenon in Malaysian culture.

Introduction: Various non-operative treatment modalities have been advocated for a frozen shoulder. In the present study we compared the efficacy of single intra-articular steroid injection vs hydrodilatation with intra-articular steroids for frozen shoulder (FS) in the frozen phase.

Materials and methods: This was a prospective, randomised control trial (RCT) done at a tertiary care centre. A total of 108 participants were randomised into two groups-one group received intra-articular steroid with hydrodilatation (HDS) and other group received intra-articular steroid injection only (S). Shoulder Pain and Disability Index (SPADI) scores were taken, and statistical analysis was done to measure the outcome at two weeks, six weeks and three-month intervals after the injection.

Result: There was significant improvement in symptoms at each interval for both the groups (p=0.0). There was no statistically significant difference in the SPADI score between the two groups at two weeks post injection, however at six weeks (p=0.04) and 3 months (p=0.001) significant difference in the SPADI score was demonstrated with better scores in group S. The mean duration of analgesia required in group HDS was 5.17 days (S.D.=1.73) and for group S was 4.28 days (S.D.=1.01), with a statistical significance (p=0.002).

Conclusion: Better clinical results were obtained at six weeks and three months with the group receiving corticosteroid only and also had a lesser requirement of analgesia post-intervention. Thus, intra-articular steroid injection only seems to be a more desirable method of management during the frozen phase of FS than that of hydrodilatation with intra-articular steroid injection.
