J arch: A contemporary soft-tissue landmark for anatomic placement of femoral tunnel in remnant-preserving anterior cruciate ligament (ACL) reconstruction

Objectives: Femoral tunnel placement is a critical step in ACL reconstruction surgery. Surgeons usually end up clearing the soft tissue to access the bony landmarks. Biological ACL reconstruction with preservation of soft tissue can be done with reliable soft tissue landmarks. Our objective is to assess the reliability of a soft tissue landmark- femoral ACL remnant, for appropriate femoral tunnel placement in soft tissue preserving ACL reconstruction. Materials and Methods: This study was a retrospective analysis of prospectively collected data of 40 consecutive patients who underwent primary ACL reconstruction in January 2018 by a single surgeon. An inverse J shaped tissue arch was identified and used as soft tissue landmark for anatomic placement of femoral tunnel. This arch was a part of femoral ACL remnant. MRI films were examined post-operatively to determine the position of the femoral tunnel. Postoperatively, MRI of these patients were reviewed to evaluate the femoral tunnel position in terms of depth and height from the proximal condylar surface and notch roof, respectively. Results: The center of the femoral tunnel was found to be at a mean depth of 27.12 ± 2.2% from the proximal condylar surface (parallel to Blumensaat’s line) and a mean height of 30.96 ± 2.75% from the notch roof (perpendicular to Blumensaat’s line), which is at par with previously defined data given by various studies. Conclusion: J arch can be used as a dependable soft tissue landmark and a guide for the anatomic placement of femoral tunnel in biological ACL Reconstruction.

Isolated MPFL reconstruction for recurrent lateral patellar instability in patients with TT-TG distance <25 mm: A calculated safe risk!

Objectives: The objectives of the study were to describe the surgical technique of our modification of isolated medial patellofemoral ligament (MPFL) reconstruction, in patients with patellar instability. As per literature, isolated MPFL reconstruction is advocated if tibial tubercle-trochlear groove (TTTG) <20 mm. Our study proposes isolated MPFL reconstruction in patients with TT-TG <25 mm and aims to determine any predisposing anatomic variants to aid in the treatment algorithm. Materials and Methods: A retrospective analysis of 52 patients with patellar instability (TT-TG <25 mm), who underwent isolated MPFL reconstruction was undertaken. The study population was divided into two groups; TT-TG <20 mm and TT-TG = 20–24 mm. Both groups were assessed radiologically and on the basis of clinical and functional outcome (KUJALA score), over 5-year follow-up period. Results: The mean age of the study population was 21.98 years, with a female (63.5%) majority. Among the 52 patients included in the study, 39 patients (75%) had TT-TG <20 mm and 13 patients (25%) had TT-TG = 20–24 mm. We noticed statistically significant improvement in both groups with respect to clinical and functional outcome, with no reported complications. None of the patients had patella alta or high grades of trochlear dysplasia. Conclusion: MPFL reconstruction without concomitant bony procedures can be safely performed in patients with a TT-TG <25 mm, in the absence of patella alta or high-grade trochlear dysplasia. Our modification of isolated MPFL reconstruction has shown excellent long-term results. In addition, our technique uses only a single interference screw, thereby reducing cost of surgery and implant hardware.

Multiple ligament knee injuries: Clinical practice guidelines

Multiple ligament knee injuries involve tears of two or more of the four major knee ligament structures, and are commonly noted following knee dislocations. These devastating injuries are often associated with soft-tissue trauma, neurovascular deficit, and concomitant articular cartilage or meniscus tears. The complexity of presentation, and spectrum of treatment options, makes these injuries unique and extremely challenging to even the most experienced knee surgeons. A high level of suspicion, and a comprehensive clinical and radiological examination, is required to identify all injured structures. The current literature supports surgical management of these injuries, with cruciate reconstructions, and repair/augmented repair/ reconstruction of collateral ligaments. This review article analyses management principle of multiple ligament knee injuries, and formulates clinical practice guidelines with treatment algorithms essential to plan individualized management of these complex heterogeneous injuries.

Arthroscopic capsular release for adhesive capsulitis secondary to diabetes provides better functional outcome than conservative management

Objectives: Comparison of outcome of subacromial bursal resection with capsular release for adhesive capsulitis of shoulder secondary to diabetes, with conservative management. Materials and Methods: This study was conducted on 68 patients of adhesive capsulitis of shoulder secondary to diabetes. The patients were divided into two groups: Arthroscopic capsular release group (group I n 32) and Conservative management group (Group II n 36) after fulfilling inclusion/ exclusion criteria. Follow-up was done at 2, 6, 24 weeks, 6 months, 1 year, and 2 years. In addition to pre-operative measurement, at each follow-up pain was assessed by visual analog scale (VAS), range of motion (ROM) was assessed by goniometer and functional outcome was assessed by Constant-Murley score. Values obtained were filled in Excel sheet and analyzed by independent t-test, Wilcoxon Rankosin test, and Analysis of Variance test on Statistical Package for the Social Sciences software. Results: Two patients in Group I and six in Group II were lost to follow-up. There was statistically significant improvement in VAS of both groups at each follow-up, but the noticeable difference was that the patients in arthroscopic release group were pain free by 6 weeks and the pain relief was sustained till final follow-up. In contrast, though there was pain relief in conservative group but they were not completely pain free till final follow-up. There was statistically significant improvement in Constant Murley score in both groups at each follow-up but arthroscopic release group achieved near normal score by 6 months and the improvement was maintained till last follow-up. The comparison of mean and median values of ROM, between the arthroscopic capsular release group and conservative group were statistically significant (P value of 0.001) for each movement. Conclusion: The improvement in ROM, decrease in pain, and functional outcome are better in diabetic patients with adhesive capsulitis undergoing Arthroscopic capsular release than conservative management.

An unusual case of anteroinferior paralabral cyst with axillary nerve compression: A case report

Paralabral cysts are an uncommon cause of shoulder pain in young adults. Their association with neurological symptoms is seldom reported in the literature. The cysts are believed to develop when there is a labral tear allowing synovial fluid entry into tissues causing one-way valve effect. This case report describes a case of anteroinferior paralabral cyst in a painful shoulder associated with axillary nerve palsy. MRI revealed an anteroinferior labral cyst. Electromyography revealed denervation of deltoid and teres minor muscles. Shoulder arthroscopy was performed with cyst decompression and labral repair. Shoulder function improved gradually and by the end of 1 year, power was back to pre-injury status. Paralabral cysts are a rare entity. When associated with nerve injury, prompt decompression is necessary to prevent irreversible nerve and muscle damage.

Arthroscopic management of synovial chondromatosis of the shoulder: A case report

Synovial chondromatosis of the shoulder is a rare entity that is generally mono-articular and uncommon in diarthrodial joints. Treatment of synovial chondromatosis of the shoulder includes open arthrotomy retrieval of loose bodies and synovectomy. With advances in arthroscopy, the same could be achieved using arthroscopic techniques. This case report describes a case report of a 35-year-old male patient who presented with complaints of pain and restriction of movement for 6 months. The MRI of the patient was suggestive of multiple loose bodies in the shoulder joint, in the subdeltoid region, and subscapularis muscle with subacromial bursitis. Arthroscopically more than 100 loose bodies were retrieved with subacromial decompression. Shoulder synovial chondromatosis has been rarely reported in the literature. The malignant transformation although rare, but it is still a possibility. The recurrence rate varies from 3.2% to 22.3%. Open arthrotomy, synovectomy, and retrieval of loose bodies cause delayed recovery and more morbidity with high chances of subscapularis insufficiency due to the need of subscapularis tenotomy. Arthroscopic treatment although have limitations such as limited visualization, limited synovectomy, and difficult interventions around the axillary recess or biceps sheath, but provides with the advantage of lesser morbidity and early rehabilitation. Synovial chondromatosis can be successfully treated arthroscopically as it provides intra-articular and extra articular access with early rehabilitation, lesser morbidity, and early recovery.

Tips and tricks of meniscal repair

With the well-established fact that meniscectomy predisposes patients to early osteoarthritis, there has been an increase in the incidence of meniscal repairs in recent years, even in active older patients, and in avascular zones. Although many techniques have been described for meniscal repair, even experienced surgeons face difficulties in certain scenarios. In this technical note, we present some techniques to facilitate the arthroscopic treatment of meniscal repair in general and introduce some novel techniques in some special scenarios.

Suggestions to improve shortcoming in reporting and data collection procedure for studies of injuries in Kabaddi

Objectives: Kabaddi is a commonly played sport in Asia and now it is getting recognition worldwide. With the emergence of this sport, concern related to injuries associated with this sport is also increasing. For uniform reporting of injuries and illness in the epidemiological study (Kabaddi), it desired to have standard definitions on Kabaddi-related injuries. Materials and Methods: After the initial review of various studies on other sports; the definitions and terms which can be valid for Kabaddi were selected and modified according to this sport. These definitions were then reviewed by experts, who have an abundance of experiences in the treatment of injuries related to this sport. After multiple meetings among the expert panel final definitions, terms, and methodology for injury surveillance studies were laid down. Results: Only new and modified definitions were used in this paper, therefore, it is advised to use this paper in conjunction with STROBE-SIS. Injury rates were defined per 1000 raids or 1000 tackles. Various definitions like match time loss, general time loss, match injury incidence, training injury incidence, match injury prevalence, etc. were included in this paper. Conclusion: These standard definitions will help inconsistent and better data collection in injury surveillance studies. This will also help in a better understanding of injury patterns.

Multiple ligament anatomic-based reconstructions of the knee: State- of-the-art

Multiple knee ligament injuries are defined as a disruption of any combination of the four main ligament complexes; the cruciate ligaments, posterolateral corner, and posteromedial corner. Evaluation requires consideration of the entire clinical picture, including injury to associated structures, directions and degree of instability, neurovascular compromise and appropriate imaging, and physical examination. Reconstruction is favored over repair and anatomic- based reconstruction techniques have been validated to restore the native biomechanics of the knee and lead to successful patient-reported and objective outcomes. Anatomic-based reconstruction of many knee ligaments simultaneously requires precise knowledge of the relevant anatomical landmarks, careful planning of reconstruction tunnel positions, and orientations to avoid tunnel convergence, and employment of immediate early motion in the post-operative rehabilitation regimen to provide the patient the best chance for relatively normal use of the affected limb.
