RESUMEN
Objectives: This study analyzed whether the isokinetic muscle strength of bilateral knee osteoarthritis patients undergoing unilateral total knee arthroplasty (TKA) is a predictor for prior surgery side. Patients and methods: In the prospective study conducted between April 2021 and December 2021, 58 knees of 29 unilateral TKA candidates (6 males, 23 females; mean age: 66.7±7.4 years; range, 53 to 81 years) were enrolled. The patients were divided into surgical (n=29)and nonsurgical (n=29) groups. The knees of patients with bilateral knee osteoarthritis (Stage III or IV) according to the Kellgren-Lawrence (KL) scale were scheduled for unilateral TKA. An isokinetic testing system was used to assess knee flexor and extensor muscle strength (peak torque) at angular velocities of 60°/sec and 180°/sec (five cycles per velocity). The radiological (X-ray-based KL scale and magnetic resonance imaging-based quadriceps angle) and clinical findings (isokinetic test and Visual Analog Scale pain scores) in both groups were compared. Results: The mean symptom duration was 10±5.4 years. The KL score and quadriceps angle showed no significant differences (p=0.056 and p=0.663, respectively). Isokinetic test results were in accordance with the clinical results of the surgery group. In the isokinetic evaluation, both the 60°/sec concentric extension (35.00 vs. 46.00, p=0.002) and flexion peak torque (18.00 vs. 26.00, p=0.001) values were significantly lower in the surgical group than in the nonsurgical group. Conclusion: Isokinetic testing can be a supportive tool for assessing the prior side of TKA in patients with bilateral knee osteoarthritis. Further studies are required to support these findings.
RESUMEN
The aim of this study was to research the associations between anterior cruciate ligament (ACL) injuries and patella alta and trochlear dysplasia in adult patients using magnetic resonance imaging (MRI). This retrospective study included 221 adult patients: 110 with acute complete noncontact ACL tears and 111 without ACL injuries who underwent knee MRI procedures between May 2016 and July 2018. After the ACL injuries were verified using the sagittal proton density images, the patellar height and patellar tendon length were measured on the sagittal T1-weighted images, and the Insall-Salvati ratio (ISR) was calculated. In the axial proton density MRI scans, according to the Dejour and Le Coultre classification of trochlear dysplasia, the knees were classified as normal or as types A, B, C, or D. The patellar length was not significantly different between the patient and control groups (41.5 ± 3.3 vs. 41.0 ± 2.9 mm, respectively). An increased patellar tendon length (46.1 ± 3.9 vs. 44.5 ± 3.4 mm, respectively) and an increased ISR (1.11 ± 0.08 vs. 1.08 ± 0.06, respectively) were measured in the patient group (with the ACL tears). In the group with the ACL tears, the rate of trochlear dysplasia was higher (15.45%) than that in the healthy group (4.5%). Of the 17 trochlear dysplasia patients in the ACL group, 11 were type A (10%), 2 were type B (1.82%), 3 were type C (2.73%), and 1 was type D (0.91%). Results showed increased patellar tendon lengths, ISRs, and trochlear dysplasia in the patients with the ACL injuries when compared with the healthy control group. Although the causative relationship has not yet been clearly elucidated, one should keep in mind that these variations may be risk factors for ACL tears.

BACKGROUND: Osteitis pubis (OP) is a common source of groin and extra-articular hip pain and is associated with intra-articular hip pathology. In this study, we aimed to determine the prevalence of osteitis pubis on magnetic resonance imaging (MRI) in non-athletic patients with cam-type femoroacetabular impingement (FAI). METHODS: This retrospective cross-sectional study included 178 subjects: 90 patients with cam-type FAI diagnosed by MRI and 88 subjects used as a control group. Additionally, their MRI data were analyzed for the characteristics of osteitis pubis, with severity graded from minimal to severe on a four-point scale. RESULTS: A total of 98 patients and 88 controls were studied. Seventy-two males (80%) and 18 females (20%) were the patient group, whereas 71 males (80.68%) and 17 females (19.32%) were the control group. The mean alpha angle of the patients with FAI was 65.8 ± 3.3° in the right side and 66.2 ± 3.2° in the left side, whereas in the control group, it was 47 ± 5.6° in the right side and 47.8 ± 5.2° in the left side. Alpha angle measurements were significantly higher in the patient group than the control group (p < 0.001). A statistically significant increase in the prevalence of osteitis pubis was found in patients with cam-type FAI (45.56%) compared to control subjects (5.68%) (p < 0.001). CONCLUSIONS: This study demonstrated that the frequency of osteitis pubis was increased in non-athletic patients with FAI syndrome. Further studies are required to determine whether these findings reflect the clinical symptoms in patients with hip pain.

OBJECTIVES: In this study, we aimed to investigate plantar fasciitis syndrome on balance and the risks of the falls. METHODS: Fifty patients with clinical diagnosed plantar fasciitis participated in this study. Patients were evaluated using the visual analog scale (VAS) for pain. Balance and fall risk were measured with the biodex balance system. Postural stability and fall risk were measured with total score (TS), antero-posterior (AP) and mediolateral (ML) as statically and dynamically at 2. and 8. degrees. Nineteen healthy volunteers with no active complaints and no previous plantar fasciitis/calcaneal spur were included in this study as a control group. RESULTS: The mean VAS value in the patient group was 6.65±1.84. There was no statistical difference between the mean age and body mass index of patients and control groups. A statistically significant difference was found between the group in TS2 (p=0.005), TS8 (p=0.009), AP2 (p=0.006), AP8 (p=0.018), DR2 (p=0.01) and DR8 (p=0.002) in favor of the control group. There was no statistical difference between the groups in the static and dynamic mediolateral balance evaluations. CONCLUSION: The findings demonstrated that postural balance, especially in the antero-posterior plane, was impaired in patients with plantar fasciitis syndrome and increased risk of falls.
RESUMEN
Tethered cord is a clinical syndrome associated with short and thick filum terminale. It can occur because of congenital or acquired reasons and can lead to progressive neurological deficits. A thorough medical history, physcial examination, imaging, and electrophysiological tests are heplful in its diagnosis. An 11-year-old patient with a prior diagnosis of spina bifida was operated for pes ekinovarus at the age of 1.5 years. The patient visited our physical medicine and rehabilitation polyclinic with complaints of pain and weakness in the left ankle and region around the knee. She had been suffering from walking disruption, thinning of leg muscles, and pain for past 1 year. After imaging, a diagnosis of tethered cord syndrome was made. Follow-up of patients diagnosed with spina bifida during growth period is important to prevent complications such as syringomyelia and tethered cord syndrome.
RESUMEN
OBJECTIVES: This study aims to investigate the isokinetic characteristics of wrist strength in flexion, extension, supination, pronation, radial, and ulnar deviation in patients with moderate or severe carpal tunnel syndrome (CTS). PATIENTS AND METHODS: Thirteen patients (23 hands) (2 males, 11 females; mean age 45 years; range 29 to 60 years) with moderate or severe CTS were compared to six healthy control subjects (12 hands) (2 males, 4 females; mean age 41 years; range 27 to 63 years) in this study, which was conducted between January 2016 and April 2016. Wrist flexion, extension, supination, pronation, radial, and ulnar deviation muscle strengths were measured at 30°/second (5 sets) angular velocity with isokinetic dynamometer. Grip strength was measured with hand dynamometer (kilograms). Boston Questionnaire was used for clinical assessment. RESULTS: Grip strength (p=0.003); wrist flexion 30°/second (p=0.014); extension 30°/second (p=0.016); and ulnar deviation 30°/second (p=0.017) muscle strengths were lower in CTS patients compared with the control group. An evaluation according to symptom duration did not reveal any significant relationship in any of the isokinetic tests with the exception of pronation 30°/second (p=0.039, r= -0.432) and ulnar deviation 30°/second (p=0.034, r=0.443) in CTS patients. No significant relationship was found between Boston Questionnaire, grip strength, and isokinetic test results. CONCLUSION: Quantitative wrist strength measurements with isokinetic dynamometers are beneficial in conservative exercise treatments and motor assessments of CTS patients.

Upper limb occlusions are rare and the clinical presentation may vary depending on the affected arteries. A detailed history and physical examination may reveal possible causes and can facilitate the differential diagnosis. It can be misdiagnosed as musculoskeletal diseases due to similar clinical manifestations. In this report, we present a case with wrist pain mimicking de Quervain's syndrome diagnosed as subacute brachial artery thrombosis due to factor II gene mutation. In conclusion, physicians should be cautious to avoid unnecessary delay in the diagnosis of thrombosis in young patients.
RESUMEN
[Purpose] The aim of this study was to investigate the usefulness of ultrasonography for the diagnosis of polyneuropathy in diabetic patients by examination of the median and ulnar nerves. [Subjects and Methods] Sixty-three diabetic patients and fourteen controls were enrolled in the study. Nerve conduction studies were performed on both upper and lower limbs. Median and ulnar nerve cross-sectional areas were measured at the wrist and forearm levels in 140 hands by ultrasound. [Results] The median nerve cross-sectional area was increased at the hook of hamatum, pisiform bone, and radioulnar joint levels in patients with carpal tunnel syndrome. The ulnar nerve area at the medial epicondyle was significantly increased in the diabetic polyneuropathy (9.2 ± 1.6), diabetic polyneuropathy plus carpal tunnel syndrome (9.3 ± 1.4), and carpal tunnel syndrome (9.2 ± 1.9) groups compared with the control group (7.7 ± 1.1). In receiver operating characteristics analysis, the cutoff value of the ulnar nerve was 8.5 mm2 at ulnar epicondyle with 71.4% specificity and 70.4% sensitivity, corresponding to the highest diagnostic accuracy for diabetic polyneuropathy. [Conclusion] Ultrasonographic examination of the median and ulnar nerves can be an alternative or additional diagnostic modality for the evaluation of neuropathies in diabetic patients.
RESUMEN
OBJECTIVES: This study aims to investigate the accuracy and effectiveness of blind and fluoroscopic-guided intra-articular shoulder injections in patients with shoulder pain. PATIENTS AND METHODS: The study included 17 patients (6 males, 11 females; mean age 52.6±9.9 years; range 36 to 66 years) with shoulder pain more than three months. First intra-articular joint injections were performed with anterior approach blindly. Following the injection and after confirming that the needle tip was intra-articular with fluoroscopy and contrast distribution, the procedure was completed using 3 mL of local anesthetic (prilocaine and bupivacaine) and 1 mL of steroid (40 mg methylprednisolone). When the contrast distribution was observed to be extra-articular at the first administration, a second injection was continued under fluoroscopy guidance. All of the injections were intra-articular with the continuation of the procedure. Pain intensity was measured with visual analog scale (VAS). RESULTS: According to the contrast distribution viewed with fluoroscopy, first blind injections were intra-articular in 11 of the 17 shoulders (64.7%). Mean of initial VAS score was 7.11. Improved pain was observed in the clinical follow-ups at the first hour (mean VAS: 2.35), third day (mean VAS: 2.64), and at the end of the first month (mean VAS: 2.23). The mean durations for blind and fluoroscopic-guided procedures excluding patients' preparation time were 0.8 minutes and 4.2 minutes, respectively. CONCLUSION: Although blind intra-articular shoulder injections are inexpensive and easily applicable, injections should be performed under fluoroscopy or another guide to ensure that the needle is intra-articular, not peri-articular.

OBJECTIVE: To determine utility of comparative electrophysiological techniques in differentiating carpal tunnel syndrome (CTS) in the background of diabetic polyneuropathy (DPN). DESIGN: Ninety diabetic patients were classified into three groups: normal, CTS, and DPN according to nerve conduction studies (NCSs). The patients in the DPN group were divided into two subgroups of DPN and DPN-CTS according to clinical criteria. The comparative electrophysiological parameters including median-radial sensory distal latency difference (M-RSLD), median-ulnar sensory distal latency difference (M-USLD) and lumbrical-interosseous median-ulnar distal latency difference (LIMULD) were compared in subgroups of DPN, DPN-CTS and CTS. RESULTS: Thirty-five (38.8%), 47 (52.3%), and 8 (8.9%) patients were diagnosed as CTS, DPN, and normal, respectively, according to NCS. After clinical stratification, 25 patients were diagnosed as DPN and 22 patients were diagnosed as DPN-CTS. The mean M-USLD and LIMULD values were similar in CTS and DPN-CTS groups, but larger than DPN statistically (p<0.05 for all). LIMULD, M-RSLD and M-USLD were positive in 88.4, 73 and 54% in the DPN-CTS group, respectively. CONCLUSIONS: Electrophysiological abnormalities were common in diabetic patients and LIMULD can identify CTS in diabetic DPN patients better than M-RSLD and M-USLD.
