Concomitant Subchondral Bone Cysts Negatively Affect Clinical Outcomes Following Arthroscopic Bone Marrow Stimulation for Osteochondral Lesions of the Talus

To study the effects of concomitant subchondral bone cysts (SBCs) on prognosis after arthroscopic bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLTs) less than 100 mm2 and to further assess the correlation between cystic OLT area, depth, or volume and postoperative outcomes. We retrospectively analyzed consecutive patients with OLTs (<100 mm2) who received BMS between April 2017 and May 2020 with a minimum follow-up of 24 months. Lesion area, depth, and volume were collected on preoperative magnetic resonance imaging. Visual analog scale (VAS), American Orthopedic Foot and Ankle Society, Karlsson-Peterson, Tegner, Foot and Ankle Ability Measure (FAAM)-Activities of Daily Life and Sports scores were assessed before surgery and at the latest follow-up. Additionally, a general linear model (GLM) and a Pearson correlation analysis (PCA) were performed to investigate the effects of concomitant cysts on postoperative results. Eighty-two patients with a mean follow-up of 39.22 ± 12.53 months were divided into non-cyst (n= 45; 39.91 ± 13.03 months) and cyst (n= 37; 38.37 ± 12.02 months) groups. There was no significant difference in the OLT area between the non-cyst and cyst groups (46.98 ± 19.95 mm2 vs 56.08 ± 22.92 mm2; P= .093), but the cyst group showed significantly greater depth (6.06 ± 1.99 mm vs 3.96 ± 1.44 mm; P= .000) and volume (248.26 ± 156.81 mm3 vs 134.58 ± 89.68 mm3; P= .002). The non-cyst group showed significantly more improvement in VAS pain, Karlsson-Peterson, Tegner, and FAAM scores than the cyst group (P < .05). The GLM indicated that SBCs negatively affected VAS pain and Tegner scores (P < .05). For OLTs with cysts, the PCA showed that an area of 90.91 mm2, depth of 7.56 mm, and volume of 428.13 mm3 were potential cutoff values associated with poor outcomes. The concomitant SBCs negatively affected the prognosis of OLTs after BMS. For OLTs with cysts, an area of 90.91 mm2, depth of 7.56 mm, and volume of 428.13 mm3 were the potential cutoff values associated with poor outcomes after BMS. Level III, retrospective comparative study.

Patients with meniscus posterolateral root tears repair during ACL reconstruction achieve comparable post-operative outcome than patients with isolated ACL reconstruction.

Lateral posterior meniscal root tear (LPMRT) repair, at the time of anterior cruciate ligament (ACL) reconstruction are increasingly being performed. The aim of this study was to compare the clinical and functional outcomes, as well as the complication rates at a minimum of 2years follow-up, between an isolated ACL reconstruction group with intact menisci and a combined ACL reconstruction and LPMRT repair group. All patients who underwent combined ACL reconstruction and LPMRT repair between 2016 and 2020 were included in the study. They were matched with an isolated ACL reconstruction group with intact menisci based on age, gender and the pre-injury IKDC score. The KOOS, ACLRSI Tegner-Lysholm score and the TELOS-test were collected pre- and postoperatively; complications (re-rupture, recurrence or persistence of a high grade pivot shift, new meniscal injury) were recorded. All LPMRTs were repaired using transtibial pull-out technique. After matching, 100 patients were included in this study (mean age 29.6 ± 1.0years and mean follow-up 42.9 ± 7.3months): 50 patients in the isolated ACL reconstruction group with intact menisci (group A) and 50 in the combined ACL reconstruction and LPMRT repair group (group B). Preoperatively, patients in group B had significant lower KOOS scores (Global 55.9 ± 2.9 vs. 64.6 ± 2.3, p = 0.02), but similar ACLRSI, TEGNER and TELOS scores. At the last follow-up, all functional scores had improved, and no significant difference between the two groups on any score was observed. There was also no difference in terms of complications rates. At a minimum of 2years follow-up (mean follow-up 42.9months), LPMRT repair during ACL reconstruction has no significant difference in terms of post-operative functional outcomes compared to the isolated ACL reconstruction group.

ACL reconstruction provides superior stability than ACL repair in patients with Schenck III and IV knee joint dislocations: first results of a 12 month follow-up study

PurposeAcute knee dislocation is a rare but devastating multi-ligamentous knee injury with only limited evidence-based surgical technique recommendations. The aim of this study was a comparison of two different anterior cruciate ligament (ACL) restoration techniques as part of an early total surgical care concept: (1) repair of ACL with additional internal bracing (ACLIB) compared to; (2) ACL reconstruction with autograft (ACLR).MethodsRetrospective, clinical-study of patients with an acute type III or IV knee dislocation (according to Schenck classification), in which the ACL was treated with ACLIB or ACLR within 12 days. The PCL was sutured and internally braced in all cases. Medial and lateral complex injuries were repaired and additionally laterally augmented by an Arciero reconstruction. After a minimum 12 months follow-up different patient-reported outcome measurements (IKDC, Lysholm, VAS, Tegner Score) and instrumental stability assessment by Rolimeter -test and stress radiographs (Telos™) were analyzed. Groups were compared by t test with p < 0.05 considered significant.ResultsIn total, 20 patients (5 IIIM, 5 IIIL and 10 IV) were included in this study with an average follow-up of 13.7 ± 2.6 months. There were significant differences in instrumental stability testing (side-to-side difference (SSD) of anterior tibial translation: ACLIB 2.7 ± 1.5 mm vs. ACLR 1.3 ± 1.3; p = 0.0339) and stress radiography (SSD ACL: ACLIB 3.4 ± 2.2 mm vs. ACLR 0.4 ± 2.7; p = 0.0249) between groups. ACLIB group showed greater ROM in terms of flexion (SSD Flexion: ACLIB 7.8 ± 9.9° vs. ACLR 16 ± 7.0°; p = 0.0466; Total Flexion overall 125.5 ± 11.8°). No clinically relevant differences in patient-reported outcome scores (Lysholm Score: ACLIB 82 ± 16.4 vs. ACLR 85 ± 10.4; IKDC subjective score: ACLIB 70.4 ± 17 vs. ACLR 76.6 ± 8.3) were determined.ConclusionACLR provides superior translational stability than ACLIB in terms of instrumental testing and stress radiography. Both techniques were equivalent with respect to PROMS and led to good and excellent clinical results.Level of evidenceRetrospective cohort study, III.

Good stability and mid-term subjective outcomes after repeated anterior cruciate ligament (ACL) revision surgery using allografts.

To evaluate the mid-term clinical outcomes of a cohort of patients who underwent multiple ACL revision reconstructions. The hypothesis was that patients with pre-existing meniscal deficiency conditions, malalignment and cartilage degeneration would have obtained lower results. All cases of multiple ACL revisions performed with allograft tissue at one single sport-medicine institution were extracted and patients with a minimum 2years of follow-up were included. WOMAC, Lhysolm, IKDC, and Tegner activity level before the injury and at last follow-up was collected and laxity evaluated with KT-1000 arthrometer and KiRA triaxial accelerometer. From a cohort of 241 ACL revisions, 28 patients (12%) with Repeated ACL Revision reconstructions were included. Fourteen cases (50%) were considered "Complex" due to the addition of meniscal allograft transplantation (8) or meniscal scaffold (3) or high tibial osteotomy (3). The remaining 14 cases (50%) were considered as "Isolate". The mean WOMAC score was 84.6 ± 11.4, Lysholm 81.7 ± 12.3, subjective IKDC 77.2 ± 12.1, and median Tegner score 6 (IQR 5-6) at pre-injury and at final follow-up. Statistically significant inferior values of WOMAC (p = 0.008), Lysholm (p = 0.02) and Subjective IKDC (p = 0.0193) were detected between "Complex" and "Isolate" revision groups. Higher average values of anterior translation at KT-1000 at both 125 N (p = 0.03) and manual maximum displacement test (p = 0.03) were reported in "Complex" with respect to "Isolate" revisions. Four patients were considered as failures and occurred in patients with "Complex" revisions, none occurred in the "Isolate" (30% vs 0%; p = 0.04). Good mid-term clinical results can be obtained after repeated ACL revision with allograft in patients who experienced multiple failures; however, those who need additional procedure due to malalignment or post-meniscectomy syndrome reported lower objective and subjective results.

Is arthroscopic assisted double tibial tunnel fixation a good option for tibial eminentia fractures?

Tibial eminentia fractures are avulsion fractures of the anterior cruciate ligament caused with additional injuries like meniscus tears or ligamentous injuries. Arthroscopic assisted internal fixation has become a preferred technique with the development of arthroscopic techniques. We aimed to present our results for arthroscopic assisted double tibial tunnel fixation in patients with displaced eminentia fracture. Twenty patients who were operated on for eminentia fracture between January 2010 and May 2014 were included in this study. All fractures were type II according to Meyers's classification. Eminentia was reduced with two nonabsorbable sutures through the ACL. Two tibial tunnels were created over the medial proximal tibia with a 2.4 mm cannulated drill. The two suture ends taken out of the 2 tibial tunnels were connected on the bone bridge between the tunnels. Patients were evaluated with Lysholm score, Tegner score, IKDC score and examined for clinical and radiological evidence of bony union. Quadriceps exercises were started on the third day. The patients were followed up with a locked knee brace in extension for 3 weeks after surgery and later patients were encouraged to mobilize as pain allowed. The preoperative Lysholm score was 75 ±3.3 and the postoperative Lysholm score was 94.5 ±3. Tegner score was 3.52±1.02 preoperatively and 6.84±1.099 postoperatively. International Knee Documentation Committee(IKDC) score was abnormal in all of the 20 patients preoperatively but normal postoperatively. The postoperative scores of the patients were statistically significant when compared with preoperative activity scores(p<0,0001). Tibial eminentia fractures may lead to pain, knee instability, malunion, laxity, or extension deficit. The technique we have described together with early rehabilitation may give good clinical results.

Nonoperative Management, Repair, or Reconstruction of the Medial Collateral Ligament in Combined Anterior Cruciate and Medial Collateral Ligament Injuries—Which Is Best? A Systematic Review and Meta-analysis

Background: Combined injury of the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL) is a common injury pattern and accounts for 20% of all ligamentous knee injuries. Despite advancements in surgical technique, there is no up-to-date consensus regarding the superiority of nonoperative versus operative management in higher-grade MCL tears of combined ACL-MCL injuries. Purpose: To interpret recent literature on treatment options and to provide an updated evidence-based approach for management of combined ACL-MCL knee injuries. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: We performed a systematic review on outcomes following treatment of concomitant ACL and MCL injuries. A computerized search was conducted in PubMed, Embase.com, and Scopus.com. Authors independently assessed eligible studies and screened titles and abstracts. Articles reporting on patients with concomitant ACL and MCL injuries with or without concomitant procedures were included. Data regarding study design, sample size, patient age and sex, length of follow-up, timing of surgery, indications, surgical methods, concomitant procedures, outcomes, and complications were recorded. Patient-reported outcomes (PROs) and functional outcomes, including Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee scores, Lysholm and Tegner scores, and range of motion, were estimated via meta-analysis and compared statistically by surgical approach. Results: In total, 18 studies were included in the systematic review with level 1 to level 4 evidence, with a total of 1,534 cases, were included in the systematic review. Of these, 16 studies with sufficient statistical reporting including 997 cases with sufficient follow-up were included in meta-analysis. Three different approaches to combined ACL-MCL injuries were identified: ACL reconstruction with (1) nonoperative MCL, (2) MCL repair, and (3) MCL reconstruction. There was no statistical difference between nonoperative versus surgically managed MCL injuries for PROs, range of motion at final follow up, or quadriceps strength. Conclusion: Reconstruction of combined injury in a delayed fashion facilitates return of range of motion and may allow time for low-grade MCL tears to heal. If residual valgus or anteromedial rotatory laxity remains after a period of rehabilitation, then concomitant surgical management of ACL and MCL injuries is warranted. Avulsion MCL injuries and Stener-type lesions may benefit from early repair techniques.

Paresthesia Is Predictive of Symptom Recurrence After Fasciotomy for Exertional Compartment Syndrome of the Leg.

Exertional compartment syndrome (ECS) is an underdiagnosed cause of lower extremity pain among athletes. The condition can be managed operatively by fasciotomy to relieve excess compartment pressure. However, symptom recurrence rates after fasciotomy are considerable, ranging from 3% to 17%. Leg paresthesia and its distribution during ECS episodes would be a significant predictor of outcomes after fasciotomy. Retrospective cohort study. Level 4. We conducted a retrospective chart review of patients who underwent fasciotomy for ECS at our center from 2010 to 2020 (institutional review board no. 21-00107). We measured postoperative outcomes including pain frequency and severity, Tegner activity level, and return to sport. Significant predictors of outcomes were identified using multivariable linear and logistic regression. P values <0.05 were considered significant. A total of 78 legs (from 42 male and 36 female participants) were included in the study with average follow-up of 52 months (range, 3-126 months); 33 participants (42.3%) presented with paresthesia. Paresthesia was an independent predictor of worse outcomes, including more severe pain at rest (P = 0.05) and with daily activity (P = 0.04), reduced postoperative improvement in Tegner scores (P = 0.04), and lower odds of return to sport (P = 0.05). Those with paresthesia symptoms in the tibial nerve distribution had worse outcomes than those without paresthesia in terms of preoperative-to-present improvement in pain frequency (P < 0.01), pain severity at rest (P < 0.01) and with daily activity (P = 0.04), and return to sport (P = 0.04). ECS patients who present with paresthesia have worse pain and activity outcomes after first-time fasciotomy, but prognosis is worst among those with tibial nerve paresthesia. Paresthesia among ECS patients is broadly predictive of more severe recurrent leg pain, reduced activity level, and decreased odds of return to sport after fasciotomy.

Effect of preoperative anterior bony impingement on lateral collateral ankle ligament reconstruction

Objective: To explore whether the combination of anterior bony impingement before surgery will affect the efficacy of the lateral collateral ankle ligament reconstruction surgery in patients with chronic ankle instability (CAI). Methods: A prospective cohort study. Patients with CAI who underwent lateral collateral ankle ligament reconstruction from January 2014 to October 2017 in the Department of Sports Medicine, Huashan Hospital, Fudan University were enrolled in this study. The patients were divided into no bony impingement group (NI group) and bony impingement group (BI group) according to the presence of bone impingement in front of the ankle during the operation. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson ankle functional socre (KAFS), Tegner score, visual analogue scale (VAS) of pain were extracted and were reevaluated at least 2 years after surgery as well as imaging evaluation of ankle. Results: A total of 59 patients were enrolled in this study. There were 29 patients in the NI group, 23 males and 6 females with a mean age of (28.4±7.1) years. And there were 30 cases in the BI group, 28 males and 2 females with a mean age of (31.9±8.6) years. The AOFAS, KAFS and Tegner scores in NI group increased from 65.8±10.6, 65.9±10.1 and 3.0 (3.0, 4.0) before the operation to 97.5±4.3, 97.8±4.7 and 6.0(5.0,6.0) after the operation, respectively; and the VAS decreased from 3.0(3.0, 4.0) to 0(0, 0); there were significant differences in those indexes before and after the operation (all P<0.05). The scores of AOFAS, KAFS and Tegner in BI group increased from 65.2±11.0, 64.2±10.0 and 3.0(3.0, 4.0) before the operation to 97.1±4.3, 97.3±4.3 and 5.0(4.0, 6.0) post the operation, respectively; and the VAS scores decreased from 3.0(3.0, 5.0) to 0(0, 1.0); there were significant differences in up-mentioned indexes before and after the surgery (all P<0.05). There was no significant differences in baseline and preoperative clinical function scores between the two groups (all P>0.05). No significant difference was found in postoperative AOFAS, KAFS and VAS scores between the two groups (all P>0.05), while postoperative Tegner score in the NI group was significantly higher than that in the BI group [6.0(5.0, 6.0) vs 5.0(4.0, 6.0), P=0.026]. Imaging evaluation of all patients showed that the reconstructed ligament was clearly visible, and the intraarticular injuries existing before surgery showed obvious signs of healing. Conclusion: Ankle lateral collateral ligament reconstruction for CAI with or without anterior bony impingement results in similar outcomes in ankle function, stability and pain levels.

Efficacy comparison between a new generation of artificial ligaments and bone-patellar tendon-bone autograft for anterior cruciate ligament revision

Objective: To compare the clinical efficacy of a new generation of ligaments (LARS artificial ligament) and bone-patellar tendon-bone (BPTB) autograft as grafts in anterior cruciate ligament (ACL) revision. Methods: A retrospective cohort study. The clinical data of 54 patients who underwent ACL revision from January 2018 to June 2020 in the First Hospital Affiliated to Army Medical University were retrospectively analyzed. There were 44 males and 10 females with a mean age of (28.5±7.7) years (15-45 years). Among them, 24 cases underwent ACL revision with LARS artificial ligament (LARS group), the other 30 cases underwent ACL revision with BPTB (BPTB group). The subjective and objective knee joint evaluation indexes were compared between the two groups to evaluate the clinical efficacy. The subjective evaluation indexes included Tegner score, Lysholm score and the International Knee Documentation Committee (IKDC) score. The objective evaluation indexes included the Lachman test, pivot-shift test, the anterior tibial translation (ATT) measurement at the weight-bearing position and the rate of patients returned to pre-injury sports. Results: The follow-up period was (32.8±5.3) months (24-42 months). At the last follow-up, the IKDC score, Tegner score and Lysholm score in the two groups significantly increased when compared with those before surgery (all P<0.05), and there was no significant difference in those indexes between the two groups (all P>0.05). The ATT measurement in the weight-bearing position was (3.1±0.7) mm in the LARS group and it was (4.1±0.9) mm in the BPTB group, which were significantly improved when compared with those before surgery (both P<0.05), and it was better in the LARS group than in the BPTB group (P<0.05). Postoperative Lachman test and pivot-shift test results in the LARS group were better than those in the BPTB group with statistically significant difference (both P<0.05). The rate of patients returned to pre-injury sports one year after surgery was 79.2%(19/24) in the LARS group and it was 50.0%(15/30) in the BPTB group, and the difference was statistically significant (P=0.029). Conclusions: Both LARS artificial ligament and BPTB autograft can achieve good short-term clinical efficacy in ACL revision, but LARS artificial ligament group has more advantages than BPTB autograft group in knee stability and early return to sports.

Medial patellofemoral ligament reconstruction in skeletally immature patients without correction of bony risk factors leads to acceptable outcomes but higher failure rates

ObjectivesTo report outcomes and re-dislocation rates of medial patellar stabilizers reconstruction without bone procedures for correction of anatomical risk factors for patellar instability in skeletally immature patients; to compare isolated medial patellofemoral ligament (MPFL) reconstruction to combined MPFL and medial patellotibial ligament (MPTL) reconstruction in this population. MethodsPatients with open physis and bone abnormalities including patella alta and/or increased tibial tubercle-trochlear groove (TT-TG) distance and/or trochlear dysplasia underwent MPFL reconstruction, either isolated or associated with MPTL reconstruction. Preoperative, 1-year follow-up and the latest follow-up (5 years minimum) data were collected. Radiological and clinical evaluations were conducted, with special attention to failure rate. Comparison of results from isolated MPFL and combined MPFL/MPTL reconstructions was performed. ResultsTwenty-nine patients were included, 19 in the isolated MPFL group (median 14 years old; follow-up 5.8 ​± ​1.7 years) and 10 in the combined MPFL/MPTL group (median 13.5 years old; follow-up 5.2 ​± ​1.4 years). Kujala and Tegner scores increased over time, although without statistically significant differences between the two groups at the latest follow-up (p ​= ​0.840 and p ​> ​0.999, respectively). During follow-up, 5 of 19 (26.3%) isolated MPFL and 2 of 10 (20%) MPFL/MPTL reconstructions experienced recurrence of patellar dislocation (p ​> ​0.999). Trochlear dysplasia type D (p ​= ​0.028), knee rotation (p ​= ​0.009) and lateral patellar tilt angle (p ​= ​0.003) were associated with patellar instability recurrence. The isolated MPFL group showed increased laxity on physical exam at the latest follow-up compared to the 1-year follow-up (patellar glide test (p ​= ​0.002), patellar tilt test (p ​= ​0.042) and subluxation in extension (p ​= ​0.019). This increased laxity was not observed in the MPFL/MPTL group (p ​> ​0.999). Comparing both groups, the glide test was significantly better in the combined MPFL/MPTL group in comparison to the isolated MPFL reconstruction group at the latest follow-up (p ​= ​0.021). ConclusionMPFL reconstruction in isolation or combined with MPTL reconstruction in skeletally immature patients with additional uncorrected anatomical patellofemoral abnormalities leads to acceptable clinical outcomes within a minimum of 5 years follow-up, although has a high failure rate of 24.1%. Addition of a MPTL reconstruction to the MPFL may result in decreased patellar laxity on physical exams, as demonstrated by better patellar glide test, patellar tilt test and subluxation in extension. Level of evidenceLevel III; retrospective cohort study.

Pregabalin does not reduce postoperative pain after outpatient ACL surgery: A case-control study

IntroductionIn France, prescribing pregabalin requires a secure prescription valid for 6 months since the decree of 12 February 2021, based on recommendations of the French Centre for Evaluation and Information on Pharmacodependence and Addiction vigilance (CEIP-A). This led to discontinuation of this treatment as a postoperative analgesic in the French ACL Study (FAST) cohort. We aimed to evaluate the impact of this change on early postoperative pain. HypothesisPregabalin is an important analgesic for reducing early postoperative pain after anterior cruciate ligament (ACL) repair. MethodsAt our healthcare facility, 584 patients from the FAST cohort who underwent primary isolated ACL reconstruction were included: 292 patients operated before June 1, 2021 who received pregabalin postoperatively and 292 patients operated after June 1, 2021 who did not receive pregabalin. The patients were matched based on age, sex, preoperative Lysholm and Tegner scores. Pain was evaluated on a visual analog scale (VAS) on D0 in the evening, D0 at night, D1, D2 and D3. ResultsThe patients who did not receive pregabalin had more severe pain at night on D0: 5.21 vs 5.68 (p=.048). There was no difference between groups in the postoperative pain at rest during the evening of D0 (p=.89), D1 (p=.33), D2 (p=.37) and D3 (p=.21). ConclusionIn the context of outpatient arthroscopic ACL reconstruction, pregabalin does not reduce early postoperative pain in a clinically significant manner. Level of evidenceIV; case-control study.

Clinical outcomes in dynamic intraligamentary stabilization technique for anterior cruciate ligament tear: A meta-analysis.

To compare the clinical outcome between dynamic intraligamentary stabilization (DIS) and anterior cruciate ligament (ACL) reconstruction in ACL tears. PubMed, the Cochrane Library, and Embase databases were searched to identify published articles on clinical studies comparing DIS versus ACL reconstruction. The results of the eligible studies were analyzed in terms of anteroposterior knee laxity translation (ΔATT) between the injured and contralateral knees, and subjective International Knee Documentation Committee (IKDC), Lysholm score, Tegner score, and ipsilateral ACL failure, implant removal, and ACL revision. Five clinical studies including 429 patients with ACL tears met the inclusion criteria. DIS showed statistically comparable outcomes of ΔATT (P = .12), IKDC (P = .38), Tegner (P = .82), ACL failure (P = .50), ACL revision (P = .29) with ACL reconstruction. A significantly higher rate of implant removal (odds ratio for DIS vs ACL reconstruction, 7.73; 95% confidence interval [CI], 2.72-22.00; P = .0001) but statistically higher Lysholm score (mean difference between DIS and ACL reconstruction, 1.59; 95% CI, 0.24-2.93; P = .02) were found in DIS group. Five clinical studies including 429 patients with ACL tears met the inclusion criteria. DIS showed statistically comparable outcomes of ΔATT (P = .12), IKDC (P = .38), Tegner (P = .82), ACL failure (P = .50), ACL revision (P = .29) with ACL reconstruction. A significantly higher rate of implant removal (odds ratio for DIS vs ACL reconstruction, 7.73; 95% CI, 2.72-22.00; P = .0001) but statistically higher Lysholm score (mean difference between DIS and ACL reconstruction, 1.59; 95% CI, 0.24-2.93; P = .02) were found in DIS group.

Arthroscopic percutaneous pullout suture transverse tunnel technique repair for tibial spine fractures in skeletally immature patients.

We introduce an arthroscopic percutaneous pullout suture transverse tunnel (PP-STT) technique for repair tibial spine fractures (TSF) in skeletally immature patients (SIPs) to avoid damage to the tibial epiphyseal and evaluate the clinical and radiological outcomes of the PP-STT technique for repair TSF in SIPs. Between February 2013 and November 2019, 41 skeletally immature patients were diagnosed with TSF; 21 patients were treated using the conventional transtibial pullout suture (TS-PLS) technique (group 1), and 20 patients were treated using the PP-STT technique (group 2). We compared clinical outcomes using the International Knee Documentation Committee (IKDC), Lysholm, Tegner, and visual analog scale (VAS) scores and participant sport levels, after a minimum of twoyear follow-up. Residual knee laxity was evaluated using Lachman and anterior drawer tests. Fracture healing and displacement were compared using X-ray. Significant improvements in clinical and radiological outcomes between preoperative and final follow-up (Lysholm, Tegner, IKDC, and VAS scores; Lachman and anterior drawer tests; and fracture displacement; p = 0.001) were achieved in both groups, with no significant between-group differences. Groups 1 and 2 exhibited no significant difference in time to radiographic healing (12.2 ± 1.3weeks vs 13.1 ± 1.5weeks, respectively; p = 0.513) or in the rate of return to sports level (19 (90.4%) vs 18 (90.0%), respectively; p = 0.826). Both surgical techniques provided satisfactory clinical and radiological outcomes. PP-STT may be a suitable alternative to protect the tibial epiphyseal for repair TSP in SIPs.

Comparative Study of Graft Healing in 2 Years after “Tension Suspension” Remnant-Preserving and Non-Remnant-Preserving Anatomical Reconstruction for Sherman Type II Anterior Cruciate Ligament Injury

To evaluate the degree of graft healing after "tension suspension" reconstruction of "Sherman II" anterior cruciate ligament injuries versus non-remnant preserving anatomical reconstruction and to compare the clinical outcomes of the two procedures. The clinical data of 64 patients were retrospectively included. There were 31 cases in the "tension suspension" remnant-preserving reconstruction group and 33 cases in the non-remnant-preserving anatomical reconstruction group. The International Knee Documentation Committee (IKDC) score, the Tegner score, and the Lysholm activity score were assessed preoperatively and at 6 months, 1 year, and 2 years postoperatively, respectively. The signal/noise quotient (SNQ) of the grafts was measured at 6 months, 1 year, and 2 years after surgery to quantitatively evaluate the maturity of the grafts after ACL reconstruction; the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) of the reconstructed ACL region of interest (ROI) were measured using DTI. A total of 64 patients were included in the study. The mean SNQ values of the grafts in the 6 months, 1 year, and 2 years postoperative remnant-preserving reconstruction (RP) groups were lower than those in the non-remnant-preserving (NRP) reconstruction group, with a statistically significant difference (p < 0.05). At each postoperative follow-up, the SNQ values of the tibial and femoral sides of the RP group were lower than those of the NRP group; the SNQ values of the femoral side of the grafts in both groups were higher than those of the tibial side, and the differences were statistically significant (p < 0.05). At 6 months, 1 year, and 2 years postoperatively, the FA and ADC values of the grafts were lower in the RP group than in the NRP group, and the differences were statistically significant (p < 0.05); the IKDC score and Lysholm score of the RP group were higher than the NRP group, which was statistically significant (p < 0.05). For Sherman II ACL injury, the graft healing including ligamentization and revascularization at 2 years after the "tension suspension" remnant-preserving reconstruction was better than that of non-remnant-preserving anatomic reconstruction.

Single Stage in Situ Suture Repair of a Multi-Ligament Knee Injury, an Observational Study

Objective: This study aims to observe the clinical outcomes associated with in situ single-stage suture repair for knee dislocation in patients suffering from multiple knee ligament injuries with the use of unabsorbable materials of the suture. Study design: A retrospective observational study Place and Duration this study was conducted in Gambat Medical College Pir Syed Abdul Qadir Shah Jellani Institute of Medical Science GIMS Gambat from May 2021 to May 2022. Methodology: In this study35 patients treated surgically with in situ suture repair were recruited. A retrospective analysis was done on 35 patients with a mean follow-up score of 3.8 ± 1.3 years. Patients were undergone in situ surgical procedures for all the ruptured ligaments followed by a proper rehabilitation protocol post-operatively. Outcome variables were assessed by Lysholm score, satisfactory score, Meyers functional rating score, VAS score, and Tegner score. Results: Results of the study states that the mean follow-up a score of VAS was recorded as 1.98 ± 0.4, Lysholm score was recorded as 82.5 ± 6.7, and the patient satisfaction score was recorded as 7.5 ± 0.9. Statistically, significant differences have been observed between the pre and post-scores of ranges of motion and Tegner activity scores with a p-value of &lt; 0.001 for both activity and ROM scores. Final follow-up of these patients reported that patients were left with no ligament laxity except for two patients who were unable to restore back to work. Among 35 patients, 5 were unable to achieve full ROM and had stiffness whereas two had infections at the surgical site. Conclusion: In situ suture repair of multiple ligaments had shown significant improvement in terms of ligament repair and early rehabilitation and therefore can be considered an effective treatment approach for the management of multiple ligament injuries. Keywords: Multiple ligament injuries, in situ repair, knee dislocation, cruciate ligament injury, single-stage repair.

Clinical Outcome after Medial Open-Wedge High Tibial Osteotomy: Comparison of Two Angular Stable Locking Plates—TomoFix™ versus LOQTEQ® HTO Plate

This study evaluated bony healing and clinical results after medial open-wedge HTO to compare the outcome of the LOQTEQ® HTO plate and the TomoFix™ internal plate fixator. A prospective, non-randomised, comparative study was undertaken. The same surgical technique for the medial open-wedge HTO was used in two treatment groups. In Group 1, the TomoFix™ implant was used for osteosynthesis, and, in Group 2, the LOQTEQ® HTO plate was used. All patients were examined before surgery (T0) and then at 12 months (T1) and at 24 months (T2) postoperatively. The primary outcome measure was the KOOS pain subscore. The secondary outcome criteria were other KOOS subscales, the Tegner score, radiological healing (RUST), and incision length. The KOOS pain subscale and the other KOOS subscores increased significantly in both groups from T0 to T1 and T2 without a significant group difference at each timepoint. The activity measured with the Tegner scale increased significantly from T0 to T2 without a significant group difference. No radiological signs of implant failure were observed in any case at the one-year X-ray, and no patient fulfilled the criteria for non-union. There was no significant difference in the frequency of adverse effects between the two treatment groups. The length of the incision was significantly shorter in the LOQTEQ® HTO group than in the TomoFix™ group. The results of this study show that patient-related outcome scores (KOOS, Tegner) increased after medial open-wedge HTO. There was no difference in clinical outcome or radiological healing between the treatment groups. Both plates are suitable for the osteosynthesis of open-wedge HTO.

The Relationship between Lower Extremity Functional Performance and Balance after Anterior Cruciate Ligament Reconstruction: Results of Patients Treated with the Modified All-Inside Technique.

Anterior cruciate ligament (ACL) ruptures are common injuries, and ACL reconstruction (ACLR) is among the most common surgical procedures in sports surgery. Our research aims to compare the 6-month post-operative results of the modified all-inside (MAI) ACLR technique, single leg hop tests (SLHT), and Y balance tests applied in different directions on the operated and non-operated sides. A retrospective cohort of 22 male recreational athletes who underwent MAI ACLR techniques performed by the same surgeon were evaluated. The functional knee strengths of the participants on the operated and non-operated sides were evaluated with five different tests of SLHTs: single hop for distance (SH), triple hop for distance (TH), crossover triple hop for distance (CH), medial side triple hop for distance (MSTH), and medial rotation (90°) with hop for distance (MRH). Their dynamic balance was evaluated with the Y balance Test. Compared to pre-operative levels, there was a significant improvement in the mean Lysholm, Tegner, and IKDC scores during the post-operative period (p < 0.05). There was a difference between SH, THD, CHD, MSTH, and MRH on the operated and non-operative sides (p < 0.05). There was no difference between Y balance scores on the operated and non-operative sides, and there were no differences between LSI scores resulting from SLHTs (p > 0.05). There were no significant relationships between YBT (composite scores) and SH, TH, CH, MSTH, and MRH distances in the healthy leg (p > 0.05), but a significant correlation with only CH in the ACL leg (p < 0.05). Our research shows that sixth-month post-operative SLHT findings were lower on the ACL side compared to the healthy side in patients tested with the MAI ACLR technique. However, when these scores are evaluated in terms of balance, it can be seen that both sides reveal similar findings. The similarity of LSIs in SLHTs applied in different directions, and balance scores of ACL and healthy sides revealed that the MAI technique is also an ACLR technique that can be used in athletes from a functional point of view.

Comparison of Anterior Cruciate Ligament Reconstruction With Versus Without Anterolateral Augmentation: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

It is clear that the anterolateral ligament has an important role in rotational knee stability. However, whether patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) can benefit from anterolateral augmentation (ALA) is still controversial. To compare the effects of isolated ACLR versus ACLR combined with ALA (ACLR+ALA) on clinical outcomes and knee stability. Systematic review; Level of evidence, 1. The methodology followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of the PubMed, Embase, and Cochrane Library Central Register of Controlled Trials databases was undertaken to identify all randomized controlled trials (RCTs) comparing isolated ACLR with ACLR+ALA for the treatment of ACL injuries in the last 15 years. The Cochrane Collaboration risk-of-bias tool and the revised Jadad scale were utilized by 2 independent reviewers to determine the quality of RCTs. Relevant data were extracted and compared between procedures, and heterogeneity across the RCTs was assessed using the I 2 statistic. The initial search yielded 849 articles. A total of 14 studies (1850 patients; 941 ACLR and 909 ACLR+ALA) satisfied the eligibility criteria for the meta-analysis. There were no significant differences between the procedures in terms of patient-reported outcomes (International Knee Documentation Committee score, Tegner score, Knee injury and Osteoarthritis Outcome Score) or return-to-sport rates. However, patients who underwent ACLR+ALA had better knee stability based on the pivot-shift test (risk ratio [RR], 1.06 [95% CI, 1.02 to 1.10]; P = .0008), Lachman test (RR, 1.03 [95% CI, 1.00 to 1.07]; P = .04), and side-to-side difference in anterior laxity (standardized mean difference, -0.55 [95% CI, -0.98 to -0.12]; P = .01) as well as a lower incidence of graft failure (RR, 0.30 [95% CI, 0.19 to 0.45]; P < .01) compared with patients who underwent isolated ACLR. ALA can be considered as a reinforcement of ACLR to improve anteroposterior and anterolateral rotational stability of the knee and reduce the risk of failure. The patient-reported outcomes of isolated ACLR were similar to those of ACLR+ALA, and both procedures provided improved knee function.

Does Accelerated Rehabilitation Provide Better Outcomes Than Restricted Rehabilitation in Postarthroscopic Repair of Meniscal Injury?

Meniscal injury is a common pathology, and the postoperative rehabilitation program is essential to patients after surgery. However, the optimal rehabilitation plan after meniscus suture is still controversial. To compare the clinical outcomes between accelerated rehabilitation and restricted programs in patients with meniscus suture (with or without anterior cruciate ligament reconstruction, ACLR). Four databases, including PubMed, Ovid, Embase, and the Cochrane Library, were searched up to November 2021. This study only included studies comparing the clinical outcomes between accelerated (immediate range of motion and weight-bearing) and restricted rehabilitation (immobilization and progressive weight-bearing) for meniscus suture. All selected studies were divided into 2 subgroups: isolated meniscus suture or combined with ACLR. The Lysholm score, Tegner score, and Knee Injury and Osteoarthritis Outcome Score were evaluated in simple meniscus sutures no less than 1year. Failure rate was evaluated in both groups, and the tunnel enlargement was additionally evaluated in patients who underwent ACLR. Eleven studies with 612 patients were eligible for analysis. The accelerated group included 4 studies with 330 participants, while the restricted group included 7 studies with 282 participants. For the patients after isolated meniscus suture, the accelerated group achieved higher Lysholm scores (mean difference = -4.66; 95% confidence interval, -8.6 to -0.73; P = .02; I2 = 88%) than the restricted group. For the patients after meniscus suture with ACLR, patients undergoing accelerated rehabilitation were associated with a significantly larger tibial tunnel enlargement in the anterior-posterior view (mean difference = -7.08; 95% confidence interval, -10.92 to -3.24; P = .0003; I2 = 0%) and lateral view (mean difference = -10.33; 95% confidence interval, -16.9 to -3.75; P = .002; I2 = 17%). This meta-analysis evaluated the effects of postoperative rehabilitation in either accelerated or restricted programs in patients with meniscus lesions after repair. A significant higher mean self-reported function was discovered at final follow-ups in the accelerated group. However, a significant increase in tibial tunnel enlargement was also found in accelerated group.
