"Foot peak pressures are comparable to normal foot after flexor hallucis longus transfer for chronic retracted tendo-achilles tear: A pedobarographic analysis of normal foot versus affected foot".

INTRODUCTION: Foot pressure changes and morbidity after flexor hallucis longus (FHL) transfer in chronic retracted tendoachilles (TA) tears have not been documented. The primary aim of our study is to analyze the peak pressure changes in various zones of the foot at each successive follow-up in the affected foot versus normal foot. The secondary aim is to determine FHL tendon healing and muscle hypertrophy. METHODS: This is a prospective study of 46 patients who underwent FHL augmentation for chronic retracted TA tears (between 2019 and 2022). Included TA tear > 6 weeks duration and retraction > 2.5 cm. Excluded open TA tear, < 6 weeks and retraction < 2.5 cm. Depending on the amount of retraction, FHL augmentation combined with TA repair/VY plasty/turn-down-plasty. Functional outcome was analyzed with AOFAS hallux metatarsophalangeal scale. Pedobarographic analysis was done pre-operatively and at 3, 6, 9 months, 1 year and at the final follow-up. Parameters studied included forefoot peak pressure (FFPP), hindfoot peak pressure (HFPP), great toe peak pressure (GTPP), first Mmeta-tarso phalangeal peak pressure (MTPP), area under the pedobarograph and maximum force. At final follow-up MRI was done to assess FHL healing and hypertrophy. Statistical analysis was done for these parameters using appropriate tests. RESULTS: Study involved 29 male and 17 female patients, mean age 49.5 years (33-65 years) and mean follow-up 26.8 months (14-38.4months). Mean hallux MTP-AOFAS score increased from 46.04 ± 7.31 preoperatively to 96.17 ± 3.22 at the final follow-up (P < 0.01). There was gradual improvement noted in FFPP, GTPP, MTPP Peak pressures at subsequent follow-ups, and by the end of 1-year foot pressures were comparable to normal side FFPP (8.02 ± 3.8 N/cm2 to 31.35 ± 3 N/cm2), GTPP(30.78 ± 13.01 N/cm2 to23.17 ± 7.5 N/cm2), MTPP(5.22 ± 2.64 N/cm2 to 23.3 ± 9.6 N/cm2). Initial high HFPP showed decline in subsequent follow-up and restored back to normal HFPP (36.91 ± 5.7 N/cm2 to 25.09 ± 3.7 N/cm2). Changes in pressures were statistically significant (< 0.001). Six patients had superficial wound infections healed with antibiotics. 23 patients who underwent a post-operative MRI showed a mean of 27 mm muscle thickness and 7.1 mm tendon thickness with complete incorporation of the FHL. CONCLUSION: Foot peak pressures though initially deranged, are restored and comparable to normal foot after FHL transfer for chronic retracted TA tear. FHL hypertrophy is observed at the muscle thickness and at the distal tendon and provides adequate strength to repair and restore foot pressures. LEVEL OF EVIDENCE III: Prospective comparative study (normal versus operated foot).

Neglected Desmoplastic Fibroma of calcaneum with collapsed hindfoot, restored with allograft transplantation: A rare case report.

Desmoplastic fibroma of the calcaneum is a rare, locally aggressive tumour. A 24-year-old female presented with long-standing heel pain, with the collapse of the calcaneum (hindfoot) that was untreated for 7 years. Eradication of this locally aggressive lesion by adjuvant therapy and restoration of calcaneal bony morphology by allograft was an arduous and challenging task. At the final follow-up, the heel was painless, and the patient could walk normally without support. Conclusion: Restoration of calcaneal height is challenging in young patients, and using structural allograft restores calcaneal and hindfoot morphology. Patient education about the high chances of recurrence despite surgical clearance is essential, and intraoperative adjuvant usage can reduce the recurrence.

Concomitant Patellar Tendon Tear (PTT) with Cruciate and/ Collateral ligament injury (Multi- Ligamentous Knee Injury -MLKI) and new pathoanatomical -Ganga PTT classification aids to strategize treatment options.

INTRODUCTION: Concomitant patellar tendon (PT) tear with cruciate or multi-ligament knee injuries (MLKI) following high-velocity injury requires a systematic approach. METHODS: The study is a retrospective case series of patients (2008-2019) with concomitant PT ligament injury with cruciate or collateral ligament injury (MLKI), including bony avulsion injuries. Isolated cruciate and MLKI without patellar tendon tears are excluded. N = 32 patients (1 female and 31 male) are divided into two groups, Group 1 (11 patients) with PT tear and ACL tear and group 2 (21 patients) with PT tear and MLKIs. Patients were taken up for a single stage in types 1,2,3 and staged repair with reconstruction for types 4,5 of our new classification. All the patients are followed up regularly, and IKDC and Lyshom's score and objective radiological stress x-rays taken at each follow-up RESULTS: Incidence of PTT combined injuries among all knee ligament injuries is 0.57%. The mean age was 35.09+/-11.96 SD(group1) and 36.55+/-11.89 SD(group2). The average follow-up was 34.45 months +/- 12.86SD (group 1) and 35.3 months +/- 15.75 SD (group2). Mean post-operative Lysholm score and IKDC score of group 1 and group 2 improvement was statistically significant p-value <=0.01. The mean post-operative ROM of the two groups were 132.73 (SD 6.46) (Group 1) and 111.75 (15.75) (Group 2) and was a statistically significant p-value <0.01. Residual lag of 30° seen in all patients improved by 3rd month in group 1 and 6th month in group 2. Knee stiffness is seen in 2 patients and superficial infection in 2 patients. CONCLUSION: PTT combined injuries are rare and occurs due to direct impact injuries. Single-stage PT repair with ACL reconstruction gives adequate stability, and extensor lag is eminent and needs supervised rehabilitation. PT with MLKI is a challenging scenario that can be performed in single-stage/multiple stages, depending on the injuries, surgical expertise, and institutional facilities. Newer simplified classification aids surgeons in planning a treatment strategy.

Arthroscopic capsular release versus manipulation under anaesthesia for treating frozen shoulder - a prospective randomised study.

PURPOSE: Arthroscopic capsular release (ACR) and Manipulation under anaesthesia(MUA) have been widely used in the treatment of frozen shoulder (FS). However, there is only limited Level-I evidence to prefer ACR over MUA. The purpose of our study was to conduct a randomised trial comparing ACR versus MUA to assess the difference in outcome, complications and cost-effectiveness of both procedures. METHODS: From May 2020 to June 2021, patients presenting with FS were randomised into two groups ACR (n = 44) and MUA (n = 41). Patients with arthritis, full-thickness cuff tears, history of trauma/previous surgery around the shoulder were excluded from the study. Range of movement (ROM), pain grading using visual analogue scale (VAS), functional scores- UCLA, CONSTANT and EuroQol-5D scores were measured pre-operatively and post-operatively. MRI was done at three weeks post-operatively for screening complications of either procedure. Quality-adjusted life years (QALY) was used for cost-analysis. RESULTS: Post-operatively, patients had significant improvement in pain, ROM and functional scores in both groups (P < 0.001) with no significant difference between groups at 24 weeks of follow-up. Diabetic patients undergoing ACR had lesser improvement in abduction and external rotation when compared to non-diabetic patients. Labral tears in MUA group and bone bruises in ACR group were the most common complications noted on the post-operative MRI. For ACR cost per QALY gained was 896 USD while that for MUA was 424 USD. CONCLUSION: Both ACR and MUA resulted in good improvement in pain and shoulder function. Good outcomes, simple technique and better cost-effectiveness would still make MUA an attractive option over ACR for treating FS.

Peek screw displacement after PCL reconstruction: A radiographic red herring solved by MRI.

Posterior cruciate ligament (PCL) repair has been increasingly performed as opposed to conservative management of PCL tears, in order to protect against future osteoarthrosis and meniscal degeneration. Fixation of the graft to bone can be done with interference screws, of which those composed of a bioresorbable material such as polyetheretherketone (PEEK) are preferred, owing to their inertness, good fixation strength and superior MR imaging compatibility. However, PEEK screws (unlike titanium screws) are radiolucent, and can make accurate post-operative evaluation by radiographs challenging. This is the first reported case of loosening of PEEK screw post-PCL repair, which highlights the importance of MRI and potential pitfall of radiography in evaluating post-surgical ligament laxity.

Outside-in technique versus inside-out semitendinosus graft harvest technique in ACLR: a randomised control trial.

BACKGROUND: Paraesthesia after hamstring graft harvest is a ubiquitous complication in the early post-operative period, and its correlation with vertical versus horizontal skin incision are well documented. The purpose of the study is to evaluate the incidence and extent/area of sensory loss of saphenous nerve branches occurring with the outside-in (OI) versus inside-out technique (IO) of semitendinosus graft harvest from the sartorius fascia and to determine a better method of graft harvest. METHODS: Sixty patients who underwent isolated semitendinosus graft harvest during anterior cruciate ligament reconstruction (ACLR) between 2016 and 2017. Patients were randomised into two groups depending on the graft harvest technique: 30 in the OI group and 30 in the IO group. The area of sensory loss was mapped on the patients' skin using tactile feedback from the patients at each follow-up (10 days, 1 month, 3 months, 6 months and 1 year). Then, the area of sensory changes for the infrapatellar branch (IPBSN) and sartorial branch (SBSN) of the saphenous nerve, incision length, graft harvest duration, and graft length were analysed statistically between the groups. RESULTS: In groups 1 and 2, 18/30 (60%) and 19/30 (63%) of patients, respectively, developed sensory changes, with no significant difference between the groups (p = 0.79). Isolated SBSN and IPBSN paraesthesia occurred in 2/60 (3%) and 19/60 (32%), respectively. Combined SBSN and IPBSN paraesthesia was present in 16/60 (27%) of patients. There was no significant difference in the area of the sensory deficit between OI and IO groups on the 10th post-operative day or at 1-month, 3-month or 1-year follow-up (p = 0.723, p = 0.308, p = 0.478, p = 0.128, respectively). However, at 6-month follow-up, the area of paraesthesia was significantly higher in the IO group (p = 0.009). The length of incision and duration of graft harvest was higher in the OI group than in the IO group (p = 0.002 and p = 0.007, respectively), and the total length of the graft was greater in the IO group (p = 0.04). CONCLUSION: Incidence is equally distributed, area of iatrogenic saphenous nerve injury gradually decreases, and recovery is seen in the majority of the patients in both graft harvest techniques. IO graft harvesting technique is better in terms of graft harvest time and cosmetics and yields longer graft; however, area of paraesthesia, though not significant, was two-fold higher than the OI technique at 1-year follow-up. CLINICAL RELEVANCE: IO graft harvest technique would enable the surgeon to adopt quicker graft harvest, smaller surgical scar and lengthier graft than the OI technique. LEVEL OF EVIDENCE: Therapeutic randomised controlled prospective study, Level II.

Insertional versus non-insertional tendoachilles tears: a comparative analysis of various predisposing factors and outcome following a repair.

BACKGROUND: Association of tendon degeneration, pre-existing posterior heel pain, Haglund's bump, retrocalcaneal spur, and mode of injury varies for the insertional and non-insertional type of tendoachilles tears (TA). PURPOSE: The study compares the various predisposing factors that determine the distinct type of TA tear and the outcome following a repair. METHODS: This is a retrospective study of the patients who underwent tendoachilles repair during January 2012-June 2018. Patients above 18 years with a minimum follow-up of two years were included. Patients with calcaneal tuberosity avulsions, prior surgeries, and open injuries were excluded. Patients were divided into groups 1 (insertional tears (IT)) and 2 (non-insertional tears (NIT)), and further subdivided based on the tendon degeneration (as D-degenerative and N-normal sub types) from ultrasound findings. AOFAS score and predisposing factors like degeneration, posterior heel pain, Haglund's bump, spur, and mechanism of injury were compared between the groups. RESULTS: The study included N = 146 with a mean age of 51.6 years and mean follow-up of 38.6 (range 24 to 96) months. IT associated with degeneration (IT-D) had a trivial fall as the predominant mechanism (P < 0.001). All patients had significant postoperative improvement of scores with no significant difference between the groups (P = 0.59) and subgroups (P = 0.27).75.34% had degenerative tendon, of which 64.5% were in the IT group and the rest in the NIT group (P = 0.02). 51.4% patients had a Haglund bump in the IT group and n.s. (P = 0.9). Forty-seven percent of patients had pre-existing posterior heel pain, 68% in IT and 32% in NIT (P = 0.04). Subgroup analysis revealed 65% of patients were in the IT-D subgroup (P < 0.001). CONCLUSION: Predisposing factors like posterior heel pain, tendon degeneration, and trivial trauma have a strong propensity for insertional TA tear. In contrast, the prominence of Haglund's bump does not predispose to a distinct type of TA tears. The outcome following a surgical repair-yields good results with no difference between the two groups.

Single-Stage Arthroscopy-Assisted Reduction and Internal Fixation (ARIF) of Tibial Rim Fracture With Posterior Cruciate Ligament Reconstruction and Repair of Posterolateral Complex and Meniscal Injury.

Multiligament knee injury with periarticular fractures are high-velocity injuries and generally require a staged treatment approach that involves multiple hospitalizations and results in delayed return to activity. We report a single-stage management technique for these injuries with arthroscopy-assisted reduction and internal fixation of a depressed tibial rim fracture with concomitant posterolateral complex repair, medial meniscal repair, and posterior cruciate ligament reconstruction.

Meniscal Root Repair Along with Auxiliary Procedures for Joint Preservation: Current Concepts.

Meniscal root repair and joint preservation surgeries have gained increased interest in the last decade, from a better interpretation of the role of meniscal functions, from the biomechanical studies. Several published results from both biomechanical and clinical studies has proven the effectiveness of meniscal root repairs and has led to a unanimous international consensus for the need for root repair surgery. Meniscal repair by suture pull-out technique is widely followed around the world and leads to adequate healing and good clinical outcome. There are auxiliary procedures like centralization sutures (to reduce the meniscal extrusion), high tibial osteotomy, cartilage repair procedures, meniscal root reconstruction and ligament reconstructions are performed along with meniscal root repair, especially in the younger patients and recently sub-chondroplasty for the bone marrow lesions (BMLs) are also executed. This review article discusses the anatomy, types of root tears, evaluation, treatment, outcomes of root repair, and the need for additional procedures, which are imperative for joint preservation and restoration of the biomechanics of the knee.

Do coracohumeral interval and glenoid version play a role in subscapularis tears?

PURPOSE: To study the effect of the coracohumeral interval and orientation of the glenoid for causation of subscapularis tears and literature review for the need of coracoplasty. METHODS: This is a retrospective cohort study of patients who underwent arthroscopic shoulder surgery from January 2013 to December 2017. The coracohumeral interval and orientation of the glenoid in patients with arthroscopically diagnosed subscapularis tears (group A, n = 40) were compared with 2 control groups (group B, n = 38 [intact subscapularis with supraspinatus and infraspinatus cuff tears] and group C, n = 39 [intact rotator cuff]). Group A1 (n = 23) consisted of the isolated subscapularis and combined subscapularis + supraspinatus tears, and group A2 (n = 17) all the 3 rotator cuff tears. The measurements were made on preoperative axial magnetic resonance imaging. Statistical analysis was performed to compare the groups. RESULTS: The mean coracohumeral interval was 8.81 ± 2.69 mm in group A and 10.62 ± 2.21 and 10.39 ± 2.59 mm in control groups B and C, respectively; this difference was statistically significant (P = .002 and .01, respectively). The mean glenoid version in patients with subscapularis tears was -3.7°, whereas the mean version in patients with intact cuff was -3.4°, and this difference was not statistically significant (P = .74). The mean glenoid version was -4.69° ± 4.22° in group A1 and -3.28° ± 4.04° in group B, with no statistically significant difference (P = .07). CONCLUSION: The coracohumeral interval was significantly decreased in patients with subscapularis tears. The glenoid was retroverted in the subscapularis group but was not statistically significant.

Does Second-Generation Suspensory Implant Negate Tunnel Widening of First-Generation Implant Following Anterior Cruciate Ligament Reconstruction?

PURPOSE: Tunnel widening following anterior cruciate ligament (ACL) reconstruction is commonly observed. Graft micromotion is an important contributing factor. Unlike fixed-loop devices that require a turning space, adjustable-loop devices fit the graft snugly in the tunnel. The purpose of this study is to compare tunnel widening between these devices. Our hypothesis is that the adjustable-loop device will create lesser tunnel widening. MATERIALS AND METHODS: Ninety-eight patients underwent ACL reconstruction from January 2013 to December 2014. An adjustable-loop device was used in 54 patients (group 1) and a fixed-loop device was used in 44 patients (group 2). Maximum tunnel widening at 1 year was measured by the L'Insalata's method. Functional outcome was measured at 2-year follow-up. RESULTS: The mean widening was 4.37 mm (standard deviation [SD], 2.01) in group 1 and 4.09 mm (SD, 1.98) in group 2 (p=0.511). The average International Knee Documentation Committee score was 78.40 (SD, 9.99) in group 1 and 77.11 (SD, 12.31) in group 2 (p=0.563). The average Tegner-Lysholm score was 87.25 (SD, 3.97) in group 1 and 87.29 in group 2 (SD, 4.36) (p=0.987). There was no significant difference in tunnel widening and functional outcome between the groups. CONCLUSIONS: The adjustable-loop device did not decrease the amount of tunnel widening when compared to the fixed-loop device. There was no significant difference in outcome between the two fixation devices. LEVEL OF EVIDENCE: Level 3, Retrospective Cohort.

Comparison of KD3-M and KD3-L Multiligamentous Knee Injuries and Analysis of Predictive Factors That Influence the Outcomes of Single-Stage Reconstruction in KD3 Injuries.

BACKGROUND: The knee dislocation-3 (KD3) injury pattern is the most common form of multiligamentous injury. Medial KD3 (KD3-M) and lateral KD3 (KD3-L) are 2 anatomically different varieties of this injury. PURPOSE: To compare the surgical outcomes of KD3-M and KD3-L multiligamentous knee injury patterns and to determine the factors that could influence the outcomes after single-stage reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A cohort of 45 patients with multiligamentous knee injuries (31 KD3-M, 14 KD3-L) who were operated on between 2011 and 2015 were compared. The cruciate ligaments were reconstructed, and the collateral ligaments were managed either conservatively or surgically depending on intraoperative laxity, tissue condition, injury site, and chronicity. The mean follow-up was 36 months (range, 24-72 months). The International Knee Documentation Committee (IKDC) score, Lysholm score, knee flexion range of motion (ROM), and laxity on stress radiographs were compared. Various factors likely to influence the outcomes were also analyzed. RESULTS: The mean IKDC score, Lysholm score, and knee flexion ROM for the 45 patients were 74.74, 87.66, and 126.78°, respectively. There was no significant difference between the KD3-M and KD3-L groups in terms of the postoperative IKDC score (P = .768), Lysholm score (P = .689), knee flexion ROM (P = .798), and laxity on stress radiographs (P = .011). Patients with a transient dislocation had better outcomes (76.51, 89.41, and 128.61°, respectively) than those with a frank dislocation (67.62, 80.66, and 119.44°) (P = .037, .007, and .043). The acute group had better outcomes (77.00, 89.51, and 127.86°) when compared with the subacute (66.26, 86.00, and 121.00°) and chronic groups (67.40, 76.40, and 125.00°) (P = .045, .006, and .486). Regression analysis showed the influence of these factors on outcomes. The presence or absence of dislocations, time frame in which surgery was performed, and follow-up duration were found to influence the outcome. All other factors had no bearing on outcomes. Two patients had knee stiffness and underwent arthrolysis. CONCLUSION: Despite anatomic and biomechanical differences between KD3-M and KD3-L injuries, single-stage management did not produce any significant difference in results. The presence of a frank dislocation, delay in surgery, and duration of follow-up were found to influence outcomes.
