A retrospective cohort analysis of arthroscopic Bankart repair with or without remplissage in patients with off-track Hill-Sachs lesion evaluated for functional outcomes, recurrent instability, and range of motion.

BACKGROUND: Lone Bankart repair is associated with high rates of recurrence, especially in off-track Hill-Sachs (HS) lesion. The objective of the study was to assess the impact of remplissage in off-track HS lesion influencing the rate of redislocation and range of motion (ROM) of the shoulder. MATERIAL AND METHOD: We retrospectively reviewed 136 patients for arthroscopic Bankart repair without remplissage (group 1, n = 77) or with remplissage (group 2, n =59) for recurrent anterior dislocation of the shoulder with glenoid bone loss of <25%. Further subgroups of on- and off-track HS lesion were based on computed tomographic assessment. At a minimum follow-up of 2 years; patients were evaluated for functional scores (Rowe, Constant-Murley, Western Ontario Shoulder Instability Index), redislocations, and ROM. RESULTS: At a mean follow-up of 54 and 44 months in group 1 and 2, respectively, there was no difference in postoperative functional scores. There were significantly more dislocations in patients with Bankart repair with off-track lesion than in patients with Bankart repair with on-track lesion (P = .02). There were significantly fewer redislocations in patients with off-track lesion who underwent Bankart repair and remplissage than in those who did not undergo remplissage (P = .0007). Compared with group 1 patients, those in group 2 revealed a statistically significant loss of ROM. CONCLUSIONS: Although a nonremplissaged off-track HS lesion remains an important risk factor for recurrent instability, remplissage also results in significant loss of shoulder ROM compared with those who do not undergo remplissage.

Does application of moderately concentrated platelet-rich plasma improve clinical and structural outcome after arthroscopic repair of medium-sized to large rotator cuff tear? A randomized controlled trial.

BACKGROUND: Platelet-rich plasma (PRP) has the potential to improve tendon-bone healing. The evidence is still controversial as to whether PRP application after repair of medium-sized to large cuff tears leads to superior structural and clinical outcome, especially after single-row repair. METHODS: In a randomized study, 102 patients (PRP group, 52 patients; control group, 50 patients) with medium-sized and large degenerative posterosuperior tears were included for arthroscopic repair with a minimum follow-up of 2 years. Patients were evaluated with clinical scores (visual analog scale score, Constant-Murley score, University of California-Los Angeles score, and American Shoulder and Elbow Surgeons score) and ultrasound to assess retear and vascularity pattern of the cuff. RESULTS: Visual analog scale scores were significantly lower in the PRP group than in controls at 1 month, 3 months, and 6 months but not later. Constant-Murley scores were significantly better in the PRP group compared with controls at 12 and 24 months, whereas University of California-Los Angeles scores were significantly higher in the PRP group at 6 and 12 months (P < .05). The American Shoulder and Elbow Surgeons score in both groups was comparable at all the times. At 24 months, retear in the PRP group (n = 2; 3.8%) was significantly lower than in the control group (n = 10; 20%; P = .01). The retear difference was significant only for large tears (PRP:control group, 1:6; P = .03). Doppler ultrasound examination showed significant vascularity in the PRP group repair site at 3 months postoperatively (P < .05) and in peribursal tissue until 12 months. CONCLUSION: Application of moderately concentrated PRP improves clinical and structural outcome in large cuff tears. PRP also enhances vascularity around the repair site in the early phase.

Functional Outcomes of Anatomic Single Bundle Primary ACL Reconstruction with Peroneus Longus Tendon (Without a Peroneal Tenodesis) Versus Hamstring Autografts.

Objectives: There is a paucity of comparative studies on the Peroneus longus tendon versus conventional hamstring autograft use in primary single-bundle ACL reconstruction. To date, there are no studies that reported donor ankle functional outcomes when a peroneus longus graft is harvested without performing a tenodesis to peroneus brevis. Methods: A single-center retrospective comparative study was undertaken to evaluate the functional outcomes (IKDC & Tegner-Lysholm scores) of primary isolated single bundle anatomic ACL Reconstruction with Peroneus Longus tendon (PL group) versus Hamstring (HT group) autografts. Further, an evaluation of donor ankle morbidity using the AOFAS score for the PL group and persistent anteromedial thigh pain and paraesthesia around the knee for the HT group was also performed. Results: 30 patients were evaluated in each group. The mean graft diameter was 8.61 +/- 0.66mm (HT) & 9.6 +/- 0.84mm (PL) and the mean graft length was 7.39cm (HT) & 7.86cm (PL) respectively. The mean IKDC scores were 58.2 (Pre-op) & 89.52 (1 year) for the HT group and 61.8 (Pre-op) & 90.9 (1 year) for the PL group respectively. The mean Tegner-Lysholm scores were 69.83 (Pre-op) & 91.96 (1 year) for the HT group and 70.66 (Pre-op) & 92.36 (1 year) for the PL group respectively.10% of the HT group had residual anteromedial thigh pain & 6.7% had paraesthesia at one-year follow-up. In the PL group, the mean AOFAS score was 96.37 +/- 2.49 at the end of one year. Two cases (6.66%) reported paraesthesia around the harvested site. Conclusion: Peroneus longus tendon appears to be a better autograft choice than hamstrings for primary ACL reconstruction. Further, without a peroneal tenodesis, the functional outcomes of the donor ankle remained excellent.

A Retrospective Study on the Efficacy, Safety, and Clinical and Radiological Outcomes of PEEK Anchors (CEPTRE® Knotted Suture Anchor and VIPLOK® Knotless Anchor) in the Treatment of Rotator Cuff Repairs.

BACKGROUND: Rotator cuff tears are a common cause of disability in the shoulder of the aging population. Rotator cuff repair is performed to address disability arising from rotator cuff tears, which fails to improve by conservative treatment. The present retrospective study was undertaken to explore the efficacy, safety, clinical, and radiological outcomes of PEEK suture anchors (Ceptre® suture anchor and Viplok® knotless anchor; Sironix, Healthium MedTech, India) in the treatment of arthroscopic rotator cuff repairs. METHOD: This is a retrospective cohort study of arthroscopic rotator cuff repair of posterosuperior tears, which was performed between January 2019 and December 2020 with a minimum follow-up of one year. The demographic data, history, preoperative clinical, magnetic resonance imaging report, and intraoperative details of each patient operated on were obtained from medical records. Post-operative clinical assessments of patients were done based on American Shoulder and Elbow Score (ASES) and Single Sssessment Numeric Evaluation (SANE) scores. Ultrasonography (USG) was done to assess any anchor pull-out and structural healing of the cuff. X-rays were performed to look for the anchor's metallic tip migration. RESULTS: A total of 65 patients were included in the study. There were 43 males (66.2%) and 22 females (33.8%). The mean age was 55.98 (±7.9) years (range: 40-69 years). The mean follow-up was 21.9 months (range: 12-46). Mean (±SD) postoperative ASES and SANE scores at the end of one year were 81.5 (±14.27) and 83.55 (±13.83), respectively. There was significant improvement with respect to the preoperative scores (p<0.0001). USG revealed complete healing in 80% of cases, partial tears in 10.8 %, and full-thickness tears in 9.2% of cases. No anchor pull-outs were noted on USG. X-rays did not reveal unusually large cystic areas in the humeral head or metallic tip migration from the humeral head at their last follow-up. CONCLUSIONS: The results of this study suggest that PEEK suture anchors (Ceptre® knotted suture anchor and Viplok® knotless anchor; Sironix, Healthium MedTech, India) are a viable option for successful surgery in the treatment of arthroscopic rotator cuff repairs without any major anchor related complications.

Improvement in condition specific and generic quality of life outcomes in patients with knee osteoarthritis following single intraarticular viscosupplementation injection.

Background: Non-operative management of Osteoarthritis (OA) can be challenging. The intra-articular injection with hyaluronic acid (IAHA), corticosteroids and Platelet rich plasma are some of the popular modalities which are increasingly being employed as a stop-gap strategy before considering any surgical intervention for OA management. Among these, the intra-articular HA (IAHA) has been widely studied with variable and conflicting results. Method: This was a prospective observational study conducted in adults with knee OA. Suitable patients were given IAHA (Synvisc-One®) on an out-patient basis. They were assessed in terms of VAS score, WOMAC score and SF36 scores at successive follow-up visits at 8, 24 and 52 weeks. Results: 50 patients were recruited in this study and followed for 52 weeks post injection of HA. Mean and SD values of VAS, WOMAC and SF36 scores were on a decreasing trend in each follow up visit. Percentage change between the visits was also statistically significant. The improvement in pain scores at successive visits was significant in KL grade 1 OA than grade 2 or 3 indicating strong association between them. Conclusion: Short-term (up to one year) beneficial effects of intra-articular viscosupplementation with HA in early primary knee OA can be seen with a decreasing trend in the intensity of pain and an increasing trend in improving the physical functioning and health-related quality of life.

Clinical and radiological outcome of acute high-grade acromioclavicular joint dislocation: A retrospective cohort study on Hook plate versus arthroscopic assisted single coracoclavicular tunnel with DogBone™ button dual FiberTape® construct.

Purpose: Hook plate (HP) is a popular implant of choice in the management of highgrade acute acromioclavicular joint (ACJ) dislocations. Recently, suspensory loop systems have drawn significant interest with comparable results and additionally does not warrant implant removal. However, no studies have compared the outcomes of HP vis-a-vis Dog Bone TM Button with dual FiberTape® (DB). Methods: 38 patients who underwent HP or Arthroscopic assisted single tunnel DB fixation to stabilize high-grade ACJ dislocations were retrospectively included in study for clinically and radiological evaluation at a minimum follow up of one year. American Shoulder and Elbow Society and Constant Murley scores were used for clinical assessment. The radiological evaluation was done by assessing quality of reduction, measuring coracoclavicular distance (CCD), and extent of subacromial erosion. Results: For final follow up evaluation, both HP and DB group had 16 patients each. The mean follow-up was 55.38 ± 10.9 and 32.88 ± 14.0 months in HP and DB group, respectively. No significant difference in mean ASES (p=0.71) and CM score (p=0.62) was found between the two groups. The DB group revealed higher CCD at the final follow-up compared to the HP group (p=0.01). Although statistically insignificant, there were more subluxations and dislocations in the DB group (37.5%) compared to the HP group (25%). The subacromial erosion was noted in all cases of the HP group at time of implant removal. Conclusion: Both groups revealed satisfactory functional and radiological outcome. However, the DB group showed a higher tendency of loss of reduction.

The promising role of autologous and allogeneic mesenchymal stromal cells in managing knee osteoarthritis. What is beyond Mesenchymal stromal cells?

Mesenchymal stromal cells (MSCs) express a wide range of properties anticipated to be beneficial for treating genetic, mechanical, and age-related degeneration in diseases such as osteoarthritis (OA). Although contemporary conservative management of OA is successful in many patients with mild-moderate OA, it often fails to improve symptoms in many patients who are not a candidate for any surgical management. Further, existing conservative treatment strategies do not prevent the progression of the disease and therefore fail to provide a long-term pain-free life. On the other hand, tremendous progress has been taking place in the exciting field of regenerative medicine involving MSCs (autologous and allogeneic), with promising translation taking place from basic science to the bedside. In this review, we comprehensively discuss the potential role of MSCs in treating OA, both autologous and off-the-shelf, allogeneic stem cells. Further, newer therapies are in the offing to treat OA, such as exosomes and growth factors.

Current concepts on management of medial and posteromedial knee injuries.

Traditionally, while managing ligament injuries around the knee, medial side injuries are frequently overlooked or considered 'benign' with very little influence on overall knee stability outcomes. However, much has changed in the recent past, and like the lateral side of the knee, it is gaining considerable attention. It is now well known that the Medial collateral ligament and Posteromedial corner are fundamentally two distinct structures that differ in anatomy and biomechanics. When it comes to decision making between conservative versus operative approach for medial side injuries, treating orthopaedic surgeons are subjected to walking on a thin line trying to balance between potential residual laxity and joint stiffness. This review will delve into some of the recent works focusing on the medial side injuries and discuss the evolving concepts.

Trends in Primary Anatomical Single-Bundle Anterior Cruciate Ligament Reconstruction Practice in Adult Patients Prevalent Among Arthroscopy Surgeons of Six Southern States of India.

Background: Although guidelines from multiple scientific studies decide the general trend in ACLR practice, there is often a variation between scientific guidelines and actual practice. Methods: A 17-member committee comprised of sports surgeons with experience of a minimum of 10 years of arthroscopy surgery finalized a survey questionnaire consisting of concepts in ACL tear management and perioperative trends, intraoperative and post-operative practices regarding single-bundle anatomic ACLR. The survey questionnaire was mailed to 584 registered sports surgeons in six states of south India. A single, non-modifiable response was collected from each member and analyzed. Results: 324 responses were received out of 584 members. A strong consensus was present regarding Hamstring tendons preference for ACLR, graft diameter ≥ 7.5 mm, viewing femoral footprint through the anterolateral portal, drilling femoral tunnel from anteromedial portal guided by ridges and remnants of femoral footprint using a freehand technique, suspensory devices to fix the graft in femur and interference screw in the tibia and post-operative bracing. A broad consensus was achieved in using a brace to minimize symptoms of instability of an ACL tear and antibiotic soaking of graft. There was no consensus regarding the timing of ACLR, preferred graft in athletes, pre-tensioning, extra-articular procedure, and return to sports. There was disagreement over hybrid tibial fixation and suture tapes to augment graft. Conclusion: Diverse practices continue to prevail in the management of ACL injuries. However, some of the consensuses reached in this survey match global practices. Contrasting or inconclusive practices should be explored for potential future research.

Clinical Guidelines in the Management of Frozen Shoulder: An Update!

Among all the prevalent painful conditions of the shoulder, frozen shoulder remains one of the most debated and ill-understood conditions. It is a condition often associated with diabetes and thyroid dysfunction, and which should always be investigated in patients with a primary stiff shoulder. Though the duration of 'traditional clinicopathological staging' of frozen shoulder is not constant and varies with the intervention(s), the classification certainly helps the clinician in planning the treatment of frozen shoulder at various stages. Most patients respond very well to combination of conservative treatment resulting in gradual resolution of symptoms in 12-18 months. However, the most effective treatment in isolation is uncertain. Currently, resistant cases that do not respond to conservative treatment for 6-9 months could be offered surgical treatment as either arthroscopic capsular release or manipulation under anaesthesia. Though both invasive options are not clinically superior to another, but manipulation could result in unwarranted complications like fractures of humerus or rotator cuff tear.

Five Year Follow up of Retrospective Cohort Comparing Structural and Functional Outcome of Arthroscopic Single-row ersus Double-row Suture Bridge Repair of Large Posterosuperior Rotator Cuff Tear in Patients Less than or Equal to 70 Years.

BACKGROUND: High re-tear rates after repairing large-sized posterosuperior rotator cuff tears remain a significant concern which may affect the clinical outcome. The most optimal type of repair (single versus double-row suture bridge) suited for large size tear remains debatable. METHODS: In a retrospective cohort study with a minimum of five years follow up, the structural and functional outcome of 103 patients with large size cuff tear repaired with single row (SR) or double row suture bridge (DRSB) were evaluated. The structural outcome was assessed with ultrasonography whereas functional outcome was evaluated with Constant Murley (CM) and American shoulder elbow score (ASES). RESULTS: There were 55 patients in the SR group and 48 patients in the DRSB group with a mean follow-up of 74.2 months (range, 60-96 months). While comparing the structural integrity in two groups, we found significantly lower re-tear rates in the DRSB group as compared to the SR group (10.4% vs. 32.7%; P=0.006). Also, there were more focal defects in the SR group (25.4%) than the DRSB group (8.3%). Overall, there was no significant difference in CM and ASES scores when the SR group was compared to DRSB. However, subgroup analysis between those with intact and retorn tendon revealed significant difference (P=0.0001) in the clinical scores. CONCLUSION: At a minimum of five years follow-up, the DRSB repair of large posterosuperior cuff tear resulted in superior structural healing over SR repair. Nevertheless, overall there was no significant functional difference between both the techniques. However, the functional outcome of the healed tendon subgroup was superior to retear tendon subgroup.

Uncommon hand injury to the batsman in 'gully cricket': report of two cases.

Volar plate injuries are typically caused by hyperextension of the proximal interphalangeal joint. These injuries are usually seen in sports where the ball comes in direct contact with the hands. Forceful dorsiflexion of the finger caused by the speeding ball leads to volar plate avulsion. In cricket, such finger injuries predominantly occur in fielders trying to catch or stop the speeding ball with bare hands. We report two unusual cases of volar plate avulsion injury occurring in batsmen that occurred during 'gully cricket' (street-cricket). We propose the possibility of a novel contrecoup-type mechanism causing this type of injury in the two cases. Both were successfully managed with splinting and had excellent recovery without any residual deformity or instability.

Does application of abduction brace after arthroscopic rotator cuff repair improve blood flow around posterosuperior rotator cuff and repair site, affecting pain levels and clinical and structural outcomes? A pilot randomized controlled trial.

BACKGROUND: As per some cadaveric studies, blood flow in posterosuperior rotator cuff tendons improves in the abducted shoulder position compared with the neutral position. In a clinical post-rotator cuff repair scenario, the impact of abduction on altered blood flow in and around the posterosuperior rotator cuff tendons is unknown in terms of clinical outcomes and structural healing. MATERIALS AND METHODS: This study included 42 eligible patients aged between 40 and 70 years with clinically diagnosed and radiologically confirmed rotator cuff tears undergoing arthroscopic rotator cuff repair. Patients were randomly allocated to undergo application of either an abduction brace (group 1) or an arm pouch (group 2). On postoperative day 1, power Doppler scanning was performed on the index shoulder in adduction and 30° of abduction in each patient; the allocated treatment (abduction brace or arm pouch) was then applied. Power Doppler scanning was repeated at 6 weeks in the immobilization position assigned to the patient (abduction or adduction). The vascular flow in 6 regions was noted as per the criteria of Fealy et al. A visual analog scale score was assessed preoperatively and at 1, 3, 6, 12, and 56 weeks postoperatively. Clinical assessment was performed with the Constant-Murley score at 1 year, and structural healing of the cuff was assessed using ultrasonography at 3 and 12 months. RESULT: On the first postoperative day, blood flow was significantly higher in all 6 areas of the shoulder in group 1 than in group 2. The mean total vascular score was significantly higher in group 1 than in group 2 on postoperative day 1 (P = .0001) and remained so at 6 weeks (P = .0001). However, significantly higher vascular flow was noted only in the peribursal region at 6 weeks in group 1 (P = .04). No significant difference in the visual analog scale score was noted between the 2 groups at any given point of follow-up. Furthermore, no clinical and structural healing differences were noted between the 2 groups at final follow-up. CONCLUSION: Higher blood flow in and around the posterosuperior rotator cuff owing to an abducted shoulder position with an abduction brace in the first 6 weeks postoperatively fails to offer any advantage in terms of lower pain levels, better clinical scores, or superior cuff healing.

Multiple Lipomatous Hemangiopericytomas in the Foot and Ankle.

Since its first description, the diagnosis and terminology of hemangiopericytoma have been in controversy. We report perhaps the first case of multiple lipomatous hemangiopericytoma occurring in the foot and ankle region.

Clinical outcome of primary medial collateral ligament-posteromedial corner repair with or without staged anterior cruciate ligament reconstruction.

INTRODUCTION: Medial collateral ligament (MCL) is a prime valgus stabilizer of the knee, and MCL tears are currently managed conservatively. However, posteromedial corner (PMC) injury along with MCL tear is not same as isolated MCL tear and the former is more serious injury and requires operative attention. However, literature is scarce about the management and outcome of PMC-MCL tear alongside anterior cruciate ligament (ACL) tear. The purpose of this study is to report the clinical outcome of primary repair of MCL and PMC with or without staged ACL reconstruction. METHODS: A retrospective evaluation was performed on patients with MCL-PMC complex injury with ACL tear who underwent primary repair of MCL-PMC tear followed by rehabilitation. Further, several of them chose to undergo ACL reconstruction whereas rest opted conservative treatment for the ACL tear. A total of 35 patients of two groups [Group 1 (n=15): MCL-PMC repaired and ACL conserved; Group 2 (n=20): MCL-PMC repaired and ACL reconstructed] met the inclusion criteria with a minimum follow-up of two years. Clinical outcome measures included grade of valgus medial opening (0° extension and 30° flexion), Lysholm and International knee documentation committee (IKDC) scores, KT-1000 measurement, subjective feeling of instability, range of motion (ROM) assessment and complications. RESULTS: While comparing group 2 versus group 1, mean Lysholm (94.6 vs. 91.06; p=0.017) and IKDC scores (86.3 vs. 77.6; p=0.011) of group 2 were significantly higher than group 1. 60% patients of group 1 complained of instability against none in the group 2 (p<0.0001). All the knees of both the groups were valgus stable with none requiring late reconstruction. The mean loss of flexion ROM in group 1 and 2 was 12° and 9° respectively which was not statistically different (p=0.41). However while considering the loss of motion, two groups did not show any significant difference in clinical scores. CONCLUSIONS: Primary MCL-PMC repair renders the knee stable in coronal plane in both the groups and further ACL reconstruction adds on to the stability of the knee providing a superior clinical outcome. Minor knee stiffness remains a concern after primary MCL-PMC repair but without any unfavorable clinical effect.

Simultaneous combined complete tear of radial and ulnar collateral ligaments of thumb in an adolescent.

Isolated tear of collateral ligaments of thumb are common but combined injuries of both radial and ulnar collateral ligaments are rare. These cases are reported in athletes involved in high-impact sports. Here, we report a case of a 15-year-old boy with pain at base of the thumb and instability following low-impact sporting activity. On subsequent clinicoradiological assessment, simultaneous combined complete tear of both radial and ulnar collateral ligaments of the thumb was noted. Delayed primary repair of both collateral ligaments was done. This case highlights the rarity of this type of injury in an adolescent and also the use of appropriate clinical tests and imaging modalities for early diagnosis of such injuries. Restoration of joint stability as early as possible either by repair or reconstruction of ligaments needs to be considered to prevent secondary osteoarthritis of metacarpophalangeal joint.

Bilateral tarsal tunnel syndrome attributed to bilateral fibrous tarsal coalition and symmetrical hypertrophy of the sustentaculum tali.

Tarsal tunnel syndrome (TTS) is one of the frequently encountered entrapment neuropathies of the lower limb. Most often the aetiology is considered to be idiopathic. However, it has to be thoroughly investigated to rule out diverse extrinsic and intrinsic causes. The sustentaculum tali (ST) forms the superior part of the distal tarsal tunnel, and any increase in its size may result in irritation of the tibial nerve or its branches, the medial and lateral plantar nerves or decrease the overall volume of the tarsal tunnel culminating to clinical features of TTS. A hypertrophied ST is an extremely rare cause for TTS, and we report perhaps a first case of bilateral TTS in a young adult due to bilateral symmetrical hypertrophied ST which in turn was a result of bilateral fibrous tarsal coalition. Staged bilateral surgical excision of the hypertrophied part of ST and the underlying fibrous tarsal coalition ensured prompt symptomatic relief.

Simultaneous, Isolated Traumatic Bilateral Patella Fractures.

INTRODUCTION: Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. CASE PRESENTATION: We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. CONCLUSIONS: In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella.

A case of bilateral aberrant pectoralis minor insertion with absent coracohumeral ligament: Clinical relevance and controversies.

Aberrant insertions of the pectoralis minor tendon are quite rare. Most cases are incidental findings during cadaver dissections, on an MRI or during surgical procedures of the shoulder joint. Rarely the aberrant insertion points can be a source of pain or restriction of the shoulder joint. From the literature review, we found that there has been no mention regarding the frequency of occurrence of this variation with respect to unilateral or bilateral occurence, and only three cases have been reported, in which aberrant bilateral insertions have been documented of which two were noted during cadaveric dissection and one radiologically. We report a rare case of aberrant bilateral insertions of the pectoralis minor, which was found during an arthroscopic procedure, and we discuss its clinical and surgical implications.
