[PMID: 39006795 PMCID: PMC11240015 DOI: 10.1016/j.asmr.2024.100914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Accepted: 02/12/2024] [Indexed: 07/16/2024] Open
Abstract
Purpose To assess outcomes of arthroscopic posterior capsular release among athletes for loss of terminal extension following anterior cruciate ligament (ACL) reconstruction. Methods A retrospective review of prospectively collected data was performed for patients undergoing arthroscopic posterior capsular release for knee extension loss following ACL reconstruction between January 2014 and December 2019. Procedure indications included extension loss greater than 10° at least 3 months after ACL reconstruction that was refractory to physical therapy. Patients were included if they were involved in either high school or college athletics, had complete outcomes of interest, and had at least 2 years of follow-up. Prospectively collected outcomes included preoperative and postoperative measurement of knee extension, International Knee Documentation Committee score, Lysholm score, return to sport data, and complications. Results Eighteen athletes with minimum 2 years of follow-up who underwent posterior capsular release following ACL reconstruction performed by a single surgeon were included in the analysis. Patients underwent surgery at an average of 16 weeks after ACL reconstruction. Knee extension improved an average of 13.8° at 2 years' follow-up (prerelease mean extension deficit 15.1°, postrelease mean extension deficit 1.3°, P < .005). Improvements in the International Knee Documentation Committee score averaged 21.7 at 6 months and 35.0 at 24 months, both of which were statistically significant (P < .001). Similarly, differences in Lysholm included a significant improvement of 23.0 and 34.2 at 6 months and 2 years, respectively (P < .001). In total, 77.8% returned to sport at an average of 9.8 months from their primary ACL surgery and 6.5 months following posterior capsular release surgery. No infections or neurovascular complications were observed. One patient required secondary release to achieve adequate extension. Conclusions For athletes with persistent knee extension loss after ACL reconstruction, knee extension was significantly improved at 2 years following arthroscopic posterior capsular release. Substantial improvements in patient-reported outcomes also were seen. In addition, subjects demonstrated a high rate of return to sport and return to preinjury performance levels. Level of Evidence Level IV, therapeutic case series.

Abstract
Purpose To systematically review the literature and provide a detailed summary of the current treatments and outcomes for arthrofibrosis following knee arthroscopy and anterior cruciate ligament reconstruction (ACLR) and to compare the treatment strategies in pediatric and adult populations. Methods A systematic review was performed in March 2022 using PubMed, EMBASE, and Cochrane Library Databases per Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Search terms consisted of variations of the following: ("arthrofibrosis" OR "stiffness" OR "stiff" OR "complications") AND ("arthroscopy" OR "arthroscop" OR "ACL" OR "anterior cruciate") AND ("treat" OR "care" OR "management" AND "knee"). The inclusion criteria were studies that were written in English, were published since 2000, and that reported outcomes of knee arthroscopy or ACLR for treatment of arthrofibrosis of the knee. The study quality was assessed, and data about the patients and treatments were recorded. Treatments were compared between pediatric and adult patients. Results A total of 1,208 articles were identified in the initial search, 42 (3.48%) of which met eligibility criteria, involving treatment regimens for arthrofibrosis following knee arthroscopy or ACLR. Of the 42 studies included, 29 (69.0%) were reported data for adults and 13 (31.0%) reported data for pediatric patients. Thirty-nine studies (92.8%) discussed manipulation under anesthesia and/or lysis of adhesions (LOA) as treatment for arthrofibrosis of the knee, whereas 2 (4.8%) described the use of medications. Conclusions Within orthopaedic sports medicine literature, there is variability in the reported treatment options for arthrofibrosis of the knee. Most studies identified manipulation under anesthesia and/or LOA as the treatment among both adult and pediatric patients. Other variants include notchplasty, open posterior arthrolysis, total graft resection, removal of hardware with LOA, dynamic splinting, casting in extension, bracing, and medications. Level of Evidence Level IV, systematic review of Level I-IV studies.

Abstract
The knee is a joint that is often injured in sport, with a large and increasing number of ligament tears and repairs; postoperative complications can lead to poor outcome, such as stiffness. Beyond the well-known and well-described intra- and extra-articular causes of postoperative stiffness, the present study introduces the concept of a central reflex motor inhibition mechanism called arthrogenic muscle inhibition (AMI). AMI occurs after trauma and can be defined as active knee extension deficit due to central impairment of Vastus Medialis Obliquus (VMO) contraction, often associated with spinal reflex hamstring contracture. This explains the post-traumatic flexion contracture that is so common after knee sprain. The clinical presentation of AMI is easy to detect in consultation, in 4 grades from simple VMO inhibition to fixed flexion contracture by posterior capsule retraction in chronic cases. After recent anterior cruciate ligament (ACL) tear, more than 55% of patients show AMI, reducible in 80% of cases by simple targeted exercises initiated in consultation. Practically, in patients who have sustained knee sprain, it is essential to screen for this reflex mechanism and assess reducibility, as AMI greatly aggravates the risk of postoperative stiffness. In case of hemarthrosis, we recommend joint aspiration, which provides immediate benefit in terms of pain and motor inhibition. In case of persistent AMI, classical electrostimulation and "cushion crush", as used by all physiotherapists, are ineffective. To reduce the risk of postoperative stiffness, no surgery should be considered until AMI has resolved. LEVEL OF EVIDENCE: expert opinion.

Abstract
Background Guided physiotherapy and surgical arthrolysis are effective in most patients with knee extension deficit. However, in refractory cases, posterior knee capsulotomy may be needed. Purpose To assess extension restoration, pain reduction, and functional improvement after arthroscopic complete posterior knee capsulotomy in patients with extension deficit refractory to guided physiotherapy and surgical arthrolysis. Study Design Case series; Level of evidence, 4. Methods Included were patients with symptomatic asymmetric extension deficit >3° refractory to at least 6 months of guided physiotherapy and initial arthrolysis (15 patients with 12-month follow-up and 8 patients with 24-month follow-up). The mean duration of extension deficit was 24.6 months. An arthroscopic complete posterior knee capsulotomy was performed with transection of the posteromedial, posterolateral and central capsule, and the posterior septum. The primary outcome measure was knee extension, with hyperextension denoted as negative knee extension values. Secondary outcome measures included visual analog scale (VAS) for pain during maximum effort and exercise, International Knee Documentation Committee (IKDC) score, and Knee injury and Osteoarthritis Outcome Score (KOOS). Results The mean patient age was 40.0 years (range, 26-70 years); 6 out of 15 patients had developed knee contracture after isolated anterior cruciate ligament reconstruction. The mean knee extension deficit decreased from 16.9° (range, 7° to 45°) preoperatively to -0.2° (range, -5° to 5°) at 12-month follow-up (P = .003) and to -0.3° (range, -5° to 5°) at 24-month follow-up (P = .035). The mean VAS pain score decreased from 3.5 (range, 1-6) preoperatively to 1.1 (range, 0-2) at 12-month follow-up (P = .004) and to 1.5 (range, 0-4) at 24-month follow-up (P = .005). The mean IKDC increased from 37.9 (range, 21-62) preoperatively to 63.9 (range, 46-87) at 12-month follow-up (P < .001) and to 60.9 (range, 39-80) at 24-month follow-up (P = .003). The mean KOOS increased from 45.0 (range, 30-62) preoperatively to 75.3 (range, 49-94) at 12-month follow-up (P < .001) and to 72.3 (range, 49-92) at 24-month follow-up (P = .003). There were no significant differences between 12- and 24-month follow-up in extension deficit or functional outcomes. One patient had a midcalf subcutaneous hematoma 5 weeks postoperatively, requiring evacuation. Conclusion Arthroscopic complete posterior knee capsulotomy was able to restore knee extension, reduce pain, and improve function, with 12-month follow-up results sustained at 24-month follow-up.

Abstract
Many surgical solutions for knee flexiondeformity in the pediatric population alter the anatomical bony alignment in the distal femur. Posterior knee capsule release has been presented as an alternative surgical procedurethat maintains the anatomical shape of relevant bones while solving the issue of knee flexion contracture. The aim of this study is to assess the results of a double-incision posteriorknee capsulotomy release performed on pediatric patients with neuromuscular or congenital severe knee flexion deformity. Thirty cases (24 patients, mean age 7.4 years) of severe knee flexion contractures were retrospectively analyzed in a cohort of varying underlying conditions (including spina bifida, muscular dystrophy, cerebral palsy, sclerodermia, and congenital patellar dislocations). Posterior knee release was performed through medial and lateral short incisions with subsequent serial casting. Range and pace of correction as well as the complication rate were recorded. Follow-up information (>1 year) included functionality (FMS scale) and pain (Kujala/Knee Injury Osteoarthritis Score [KOOS]) scales. Significant correction in the knee position was achieved in all analyzed knees (from mean 40.2° to 0.7°; P < 0.01). Twenty-nine out of 30 cases achieved correction by 7 days postoperatively (average number of casts: 1.93 ± 1.05). Overall complication rate in the analyzed cohort reached 6.7% (2/30 cases; double metaphyseal fracture and arthrofibrosis). At follow-up (22.3 months on average), functional ambulation and pain parameters improved drastically, with no further complications observed. Double-incision posterior knee release is an effective method of knee contracture release, which does not affect the axial alignment of the distal femoral bone. Thus, posterior knee release should be considered as potential alternatives to osteotomies and eight-plate corrections, which are currently the basic methods of knee contracture treatment.

Abstract
Purpose To 1) evaluate the clinical efficacy of arthroscopic posterior capsular release for improving range of motion (ROM) in cases of recalcitrant flexion contracture and 2) determine patient-reported outcomes (PROs) postoperatively. Methods Retrospective chart review was performed to identify patients who underwent arthroscopic posterior capsular release due to persistent extension deficit of the knee despite comprehensive nonoperative physical therapy between 2008 and 2021. Knee ROM and PROs (International Knee Documentation Committee [IKDC], Tegner, and visual analog scale [VAS]) were collected at final follow-up. Results Overall, 22 patients were included with a median age of 37 years (interquartile range [IQR]: 20.5-44.3). Of these, 8 (36%) were male and 14 (64%) were female, and average follow-up was 3.7 ± 3.3 years. The most common etiology was knee flexion contracture after anterior cruciate ligament (ACL) reconstruction (59%). All patients failed a minimum of 3 months of nonoperative management. Prior to operative intervention, 100% of patients received physical therapy, 64% received extension knee bracing or casting, and 36% received corticosteroid injection. Median preoperative extension was 15° (IQR: 10-25) compared to 2° (IQR: 0-5) postoperatively (P < .001). At final follow-up, median extension was 0° (IQR: 0-3.5). Postoperative VAS pain scores at rest (2 vs 0; P = .001) and with use (5 vs 1.8; P = .017) improved at final contact, and most (94%) patients reported maintaining their extension ROM. Patients with ACL-related extension deficit reported better IKDC (81 vs 51.3; P = .008), Tegner (5.8 vs 3.6; P = .007), and VAS pain scores (rest: 0.2 vs 1.8; P = .008; use: 1.3 vs 5; P = .004) compared to other etiologies. Conclusion Arthroscopic posterior capsular release for recalcitrant flexion contracture provides an effective means for reducing pain and restoring terminal extension. The improvement in extension postoperatively was maintained for most (94%) patients at final follow-up with a 14% reoperation rate.

Abstract
PURPOSE To assess the recovery of extension and improvement in functional scores after an arthroscopic or open posterior knee capsulotomy in the setting of an extension deficit. METHODS A systematic search of articles published between 1980 and 2020 was performed in the MEDLINE/PubMed database, EMBASE/Ovid database and Web of Science database. The inclusion criteria consisted of patients with primary extension deficits > 5° who underwent an arthroscopic or open posterior knee capsulotomy. The assessed outcomes were preoperative and postoperative range of motion and functional outcome scores. Randomized controlled trials, cohort studies and case series with a follow-up longer than 6 months were included. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool for case series. The certainty of evidence was assessed using the GRADE approach. RESULTS Of 226 records identified through database searching, 7 studies were included in the final analysis. The outcomes of 107 patients with a mean age of 34.1 (range 15-63) years were available. In all the included studies, a posterior capsulotomy resulted in the restoration of knee extension to normal or nearly normal values (mean postoperative extension deficit: 0.4-4.2 degrees) with a significant increase in functional outcome scores. No neurovascular complications were reported within the studies. Due to the diverse methodology of studies, the direct comparison of arthroscopic versus open approaches was not possible. Concerning the risk of bias assessment, the greatest concerns raised the selection of participants among the included studies and the methods of outcome measurement. The certainty of evidence was very low according to the GRADE. CONCLUSIONS Both arthroscopic and open posterior capsulotomy of the knee results in restoration of normal or nearly normal knee extension and significant improvement in functional outcomes. LEVEL OF EVIDENCE IV.

Abstract
Knee flexion contractures can arise from posterior capsule arthrofibrosis secondary to trauma, surgery, or chronic degenerative disease. This leads to limited knee extension and increased mechanical stress on the contralateral joint. Depending on the severity of the contracture, a treatment option may include surgical release of the posterior capsule. Arthroscopic posterior capsular release has been reported previously to have excellent resolution of extension deficits with minimal risk of postoperative complications. These techniques typically use an array of instruments, including shavers, biters, or scissors to perform arthrolysis of the posteromedial and posterolateral capsules. Our primary objective is to present a modified arthroscopic surgical technique for percutaneous treatment of knee flexion contracture using a spinal needle to perform a posterior capsule release.

Abstract
Lack of full extension of the knee is a disabling condition that sometimes needs to be treated by a posterior capsulotomy of the knee. However, it is not clear if the full extension acquired can be kept throughout long-time follow-up. We conducted a retrospective cohort study of 20 patients diagnosed with minimal flexion contracture of the knee who underwent open posterior capsulotomy between 1990 and 2010. All patients (100%) presented with a preoperative Lysholm's score classified as poor or fair (mean = 58.6 ± 13.8, 95% confidence interval [CI]: 52.3-64.9), but 14 patients (70%) experienced an improvement to good or excellent scores (mean = 87.6 ± 8.8, 95% CI: 83.6-91.6) after the follow-up. The mean preoperative angle of fixed flexion was 25.0 ± 9.1 degrees (95% CI: 20.8-29.2), and it decreased to 4.2 ± 4.1 degrees (95% CI: 2.3-6.1) after the follow-up. We conclude that posterior capsulotomy of the knee proved to be an effective procedure to treat properly patients with painful knees secondary to lack of full extension after 10.3 years of follow-up.

PHYSIOTHERAPY RESEARCH INTERNATIONAL 2020; 25:e1826.

Abstract
BACKGROUND AND PURPOSE Anterior cruciate ligament (ACL) ruptures are common knee injuries, and siblings of individuals with an ACL injury may be at higher risk of ACL injury. Generalized hypermobility may be a familial factor predisposing siblings to ACL injury and may also relate to faulty lower limb alignment. There is a need to determine whether the interaction between hypermobility, family history, and faulty alignment makes siblings with hypermobility at higher risk for ACL injury so that appropriate preventative measures can be taken. This study therefore aimed to (a) compare the prevalence of generalized hypermobility and faulty limb alignment in siblings with and without injury and (b) assess the relationship between generalized hypermobility and lower limb alignment. METHODS In this case-controlled study, 24 siblings with ACL injuries from 10 families were matched with 24 healthy uninjured siblings from 10 unrelated families. Generalized hypermobility was assessed using Beighton's criteria. Chi-square analyses compared generalized hypermobility and lower limb alignment between siblings and sibling pairs with and without injuries. Spearman's rho was used to assess correlations between generalized hypermobility and lower limb alignment. RESULTS There were significant differences between the number of injured and uninjured siblings demonstrating generalized hypermobility when tallied individually (p = .003) and in same-family sibling pairs (p = .019). Significant (or close) differences were found between siblings for knee hyperextension (p < .001), knee valgus (p = .01), and foot pronation (p = .002) and for sibling pairs sharing knee hyperextension (p < .001), knee valgus (p = .06), and foot pronation (p = .06). Generalized hypermobility correlated with knee hyperextension (rs = .722; p < .001), knee valgus (rs = .385; p = .007), and foot pronation (rs = .328; p = .023). CONCLUSIONS Generalized hypermobility and faulty limb alignment occur significantly more frequently in injured than uninjured families. Screening for both features would assist in identifying at-risk siblings. Prevention programmes reduce ACL injuries by 50-70% and should target hypermobile siblings of the ACL injured.

Abstract
BACKGROUND Loss of motion (LOM) remains a common complication after anterior cruciate ligament (ACL) reconstruction and can be detrimental to patient outcomes after surgery. LOM is multifactorial, but nonsurgical and surgical solutions to this complex problem are available. A paucity of quality data exists evaluating clinical outcomes after the surgical treatment of patients with LOM after ACL reconstruction. HYPOTHESIS Patients undergoing surgical lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction will exhibit decreased function, lower outcome scores, and delayed time of release to play when compared with matched controls without LOM. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A database of 1572 patients undergoing ACL reconstruction was sampled from 2013 to 2017 to identify a total of 58 patients (LOM group [n = 29] vs matched control group [n = 29]). Group comparisons were examined for patients requiring a second surgical procedure for LOM versus matched controls after ACL reconstruction for differences in surgical timing, self-reported International Knee Disability Committee scores, objective function at release to play, and subjective knee function at 2 years with the Single Assessment Numeric Evaluation. The risk of a type I error was set at α = .05 for all statistical analyses. RESULTS Patients who underwent lysis of adhesions and manipulation under anesthesia for LOM after ACL reconstruction exhibited no differences in Single Assessment Numeric Evaluation knee function at 2 years when compared with matched controls (85.8 ± 14.9 vs 88.0 ± 10.8, P = .606). All patients met release-to-play criteria. Only International Knee Disability Committee scores (P = .046) and single-legged hop testing (P = .050) reached statistically significant differences, with higher scores in the control group. There was no difference in the time to release to play (P = .034) or level of participation (P = .180) between the control and surgical groups. Subjective function scores at 2 years were not significantly different between groups. Tourniquet time during the index ACL reconstruction was shorter in the control group (P = .034). CONCLUSION The findings of this study suggest that patients who undergo surgical treatment for LOM after ACL reconstruction can release to play at similar times but display relative deficits in single-legged-hop symmetry and lower self-reported function when compared with matched controls. Longer surgical times may increase the risk for LOM after ACL reconstruction. REGISTRATION NCT03704376 (ClinicalTrials.gov identifier).

Abstract
PURPOSE Posterior capsular contracture is a potential consequence of osteoarthritis, post-traumatic arthritis, and surgical procedures of the knee. Many patients who undergo TKA will be found to have some degree of flexion contracture intraoperatively, which necessitates posterior capsular release. There is no information in the literature about the safety of posterior capsular release done during TKA. The present cadaveric study investigates the safety of posterior capsular release during TKA. METHODS This study involved ten fresh-frozen cadaver specimens, each of which underwent three successive releases of the posterior capsule medially, laterally, and in the midline. One senior joint surgeon performed this procedure with a 1.27 cm curved osteotome, hugging the bone posteriorly on the distal aspect of the femur until the osteotome moved freely behind the bone without resistance. The distance from the distal aspect of the femur to the tip of the osteotome was then measured. Finally, the popliteal fossa was dissected, and the course of the neurovascular bundle was followed to assess for any macroscopic injury. RESULTS The capsule was penetrated at a median depth of 13.6 cm (range 10.3-17.6). Even at this depth, no injuries to the popliteal artery, tibial nerve, or popliteal vein occurred in any of the 30 penetrating events. CONCLUSION This study suggests that posterior capsular release can be performed safely with this technique.

Abstract
INTRODUCTION Knee extension deficit or loss of extension (LOE) is a potential complication following ACL reconstruction (ACLR); however, the change in postoperative knee extension during rehabilitation is not well defined. The aim of this review is to establish the trajectory of knee extension recovery and incidence of knee extension deficit during rehabilitation after ACL rupture. METHODS AND ANALYSIS A systematic search will be conducted in MEDLINE, Embase, Cochrane Library, Scopus, SPORTDiscus, and relevant trials databases of English language papers in publication as of May 2018, with no restrictions on publication year applied. References will be screened and assessed for eligibility by two independent reviewers as per the PRISMA guidelines. Cohort, cross-sectional or case-controlled studies will be included for the analysis. Data extraction will be conducted using a predefined template and quality of evidence assessed. Statistical summaries and meta-analyses will be performed as necessary. ETHICS AND DISSEMINATION This review will provide clearer definitions for the measurement and interpretation of postoperative knee extension and establish its natural history after ACL reconstruction. Evidence of the incidence and factors associated with loss of extension will be identified. The findings of this systematic review will be disseminated in peer-reviewed journals and presented at national/international conferences. TRIAL REGISTRATION The protocol was registered on the PROSPERO international prospective register of systematic reviews prior to commencement (registration number CRD42018092295 ).

Abstract
The treatment of joint contracture continues to represent a challenging problem in orthopedic surgery and rehabilitation medicine. Existing animal models of knee contracture for evaluating new treatments are mostly created by extensive joint tissue damage with Kirschner-wire immobilization which requires a second surgery to remove Kirschner-wires. This study aimed to develop a less invasive rabbit model of moderate knee contracture through a single surgery. Skeletally mature New Zealand White rabbits had their right knee operated to create surgical damage to the posterior capsule under direct visualization. Operated knees were then held in a flexed position by suturing the superficial flexion muscles with absorbable sutures. The flexion contracture (net extension loss) was determined by comparing the extension angles between the operated and non-operated knees from 8 to 24 weeks post-surgery. The flexion contracture of the operated knees was significantly greater (p < 0.01/0.001) than the non-operated knees at each weekly measurement. The mean flexion contractures were 22° at 8 weeks, 19° at 16 weeks, and 18° at 24 weeks. No significant differences in the severity of flexion contracture were observed between 8-week and each of the following weeks, suggesting that the flexion contracture was essentially stabilized by 8 weeks post-surgery. Histopathologic analyses demonstrated intra-articular and peri-articular scar formation. This less invasive rabbit model of moderate knee contracture is more quickly established through a single surgery with lower risk of surgical complications compared to the previously reported invasive models, and could be an alternative animal model for joint contracture research. © 2018 Orthopaedic Research Society.

Abstract
BACKGROUND Some patients with recurrent symptomatic instability after primary anterior cruciate ligament (ACL) reconstruction have an extension deficiency (ED). This study (a) compared preoperative clinical conditions between the ED and non-ED groups undergoing revision ACL reconstruction, (b) documented clinical and arthroscopic findings in ACL-reconstructed patients with reinstability and ED, and (c) determined whether the ED could be resolved and whether the clinical results of revision surgery differed between the ED and non-ED groups. METHODS This study included 58 patients who underwent revision ACL reconstruction. Patients were divided into the ED and non-ED groups. Preoperatively, the demographics and clinical conditions of the two groups were compared. Intraoperatively, the pathological structures that related to ED were documented. After surgery, the degree of postoperative ED and functional outcomes were compared between the two groups at 2-year follow-up. RESULTS The International Knee Documentation Committee subjective score and SF-36 physical component summary scores were worse in the ED group than the non-ED group preoperatively (54 vs 48 [P = 0.014]; 42 vs 39 [P = 0.031], respectively). Intraoperatively, the ED group showed significantly more frequent graft malposition (50% vs 5%), anvil osteophytes (44% vs 0%), and scarring around posterior intercondylar notch (100% vs 0%). However, there was no difference in the degree of postoperative ED and functional outcome between the two groups at follow-up. CONCLUSIONS ED in patients with recurrent instability after primary ACL reconstruction could be treated with good clinical result by addressing the pathological conditions causing ED in addition to ACL re-reconstruction.

Abstract
The loss of knee extension, even if minimal, is disabling and considerably affects the individual's quality of life. This loss of extension can be a consequence of prior surgery, including a previous anterior cruciate ligament reconstruction. Although this loss of extension may be treated through an isolated arthroscopic procedure, a more severe case may warrant an invasive approach. In these cases, a posterior capsulotomy of the knee may be done if all conservative measures have been exhausted. This procedure has been proven to be safe and effective in the re-establishment of full extension in the setting of a minor flexion contracture of the knee. The purpose of this Technical Note was to describe our preferred technique when performing an open posterior capsulotomy of the knee for the treatment of minimal extension deficit.

Abstract
BACKGROUND Postoperative extension deficits following anterior cruciate ligament (ACL) reconstruction can cause major limitation during daily life. The purpose of this study was to evaluate the efficiency of an all-arthroscopic approach and posterior capsule release for the treatment of persistent knee extension deficits following ACL reconstruction. METHODS Between 2009 and 2013 a total of 10 patients with knee flexion contractures after ACL reconstruction were assessed following an all-arthroscopic approach and posterior capsulotomy. The clinical outcomes were reviewed using the range of motion (ROM), Tegner Activity Level, Lysholm score and visual analogue pain scale (VAS). RESULTS Four women and six men with a median age of 34years (range: 17 to 49years) were included in the study. The median follow-up period was 25months (range: 14 to 69months). The median preoperative extension deficit was 15° (range: 10 to 20°) compared to the normal contralateral knee. Postoperatively at final follow-up the median extension deficit was one degree (range: 0 to five degrees) (P<0.01). The median preoperative Lysholm score improved from 52 (range: 32 to 67) to 92 (range: 84 to 100) postoperatively (P<0.01), while the median Tegner Activity Level improved from three (range: two to six) to six (range: three to seven) respectively (P<0.02). The median VAS status for pain decreased from five (range: one to 10) to one (range: 0 to three) (P<0.01). No complications were observed. CONCLUSIONS Arthroscopic posterior capsulotomy is a safe and effective additional procedure in the treatment of persistent knee extension deficits following ACL reconstruction with excellent results regarding ROM and subjective outcomes. LEVEL OF EVIDENCE Level IV.
