Journal of Medicine University of Santo Tomas 2019;3(1):270-276
Background:
Anterior Cruciate Ligament (ACL) reconstruction is commonly performed to restore knee
kinematics and halt the progression of osteoarthritis.
A primary variable that could infl uence the outcome
of ACL reconstruction is the tension applied to the
graft at the time of fi xation. If the tension is too great,
an abnormal compressive force could potentially develop across the tibiofemoral joint, hindering knee
motion, and subjecting the articular surfaces to increased stress. If the tension in the graft is too low,
the graft will not be effective in restoring normal kinematics. The Tegner Lysholm Knee Scale is a functional scoring for patients with ligamentous injuries. It is
a patient-reported measure of knee function and is
important for comprehensive assessment conditions
in both the clinical and research context. Our objective was to compare which tension technique (15 lbs graft tension using a Mitek Tensioner™ vs maximal
sustained two-hand technique) would yield better
functional outcome at 6 months and 12 months postoperatively using the Tegner Lysholm Knee Scale.
Methods :
Twenty-nine patients who underwent arthroscopic ACL reconstruction at the University of
Santo Tomas Hospital Private Division were randomly divided equally into two groups (group A or group
B). During tibial fi xation, group A would receive 15
lbs graft tension using a Mitek Tensioner and group
B would receive graft tension using the maximal sustained two-handed pull technique. The patients underwent a standard rehabilitation protocol at an institution of their choice and a Lysholm Scoring Scale
and Tegner activity scale were self-administered at 6
months and 12 months after the surgery in order to
assess their functional outcome.
Results :
The results showed that the functional outcome scores of group A were higher than group B.
The yielded p-value was 0.10 (6 months), 0.07 (12
months) for group A and 0.27 (6 months), 0.46 (12
months) for group B. The results showed no suffi cient
evidence of a signifi cant difference between the effects of arthroscopic ACL reconstruction with 15 lbs
weight using a Mitek Tensioner (group A) and graft
tension using the maximal sustained two-handed pull technique (group B) in the knee functional outcome of
patients at 6 months and 12 months postoperatively
Conclusion
The functional outcome scores of patients who underwent ACL reconstruction using different graft tension did not show signifi cant results.
Further re-evaluation of patients’ functional outcome
score is necessary after 12 months postoperatively.
The desired tensioning technique of the ACL surgeon
would be at his/her convenience knowing beforehand the pros and cons of each technique.

2.Open Wedge High Tibial Osteotomy and Combined Arthroscopic Surgery in Severe Medial Osteoarthritis and Varus Malalignment: Minimum 5-Year Results
The Journal of Korean Knee Society 2016;28(4):270-276
PURPOSE: To evaluate the radiologic and functional outcomes of medial open wedge high tibial osteotomy (HTO) combined with arthroscopic procedure in patients with medial osteoarthritis. MATERIALS AND METHODS: From June 1996 to March 2010, 26 patients (32 knees) who underwent medial open wedge osteotomy and arthroscopic operation for medial osteoarthritis were retrospectively reviewed. Measurements included hip-knee-ankle (HKA) angle, femorotibial angle, medial proximal tibial angle, posterior tibial slope angle, and Kellgren-Lawrence grade. Clinical evaluation was performed using Lysholm knee scoring scale and knee and function score of the American Knee Society. RESULTS: Differences between the mean preoperative and postoperative measurements were significant in all angles including the HKA angle (−5.7° and +5.5°), femorotibial angle (−1.9° and +9.8°), and medial proximal tibial angle (82.9° and 90.5°) (p<0.05). Mean Lysholm knee scoring scale was 63.6 preoperatively and 88.7 at the last follow-up, mean Knee Society knee score was 61.2 and 86.6, and mean function score was 59.3 and 87.2, respectively. All differences were significant (p<0.05). CONCLUSIONS: Medial open wedge HTO in combination with arthroscopic procedure is an effective treatment method for medial osteoarthritis to treat varus deformity and an intra-articular lesion.

PURPOSE: High Outerbridge grade lesions of the articular cartilage have been associated with poor outcomes of high tibial osteotomy (HTO). However, there has been no report on the efficacy of HTO in the presence of kissing lesions. The purpose of this study was to compare clinical and radiographic outcomes of HTO between kissing lesion and non-kissing lesion groups. MATERIALS AND METHODS: Of the patients with medial compartment osteoarthritis and varus deformity treated with HTO between 2007 and 2012, 21 cases with kissing lesions and 22 cases without kissing lesions were selected. Clinical outcomes were assessed using the Lysholm knee scoring scale score, visual analogue scale score, Hospital for Special Surgery score, Western Ontario and McMaster Universities score, and Tegner activity score. Radiographic outcomes were assessed using the femoral-tibial angle, mechanical axis deviation, medial proximal tibial angle, posterior tibial slope angle, and joint space width. RESULTS: Clinical outcomes were improved in both groups from the postoperative assessment to the final follow-up, which showed no statistically significant difference between groups at the final follow-up. No statistically significant differences were observed with regard to radiographic assessment. CONCLUSIONS: Since both groups showed favorable short-term clinical and radiographic outcomes, HTO might be an alternative treatment option for degenerative osteoarthritis with kissing lesions in relatively young patients.

PURPOSE: The purpose of this study is to compare the clinical and radiographic outcomes of high tibial osteotomy (HTO) and unicompartmental arthroplasty (UKA) in advanced medial compartment arthritis accompanied by kissing lesions in relatively young patients. MATERIALS AND METHODS: Forty-five patients were divided into the HTO (n=23) and UKA (n=22) groups. Clinically, we evaluated the Lysholm knee scoring scale, visual analogue scale, Hospital for Special Surgery, and Western Ontario and McMaster Universities Osteoarthritis index scores preoperatively, 6 and 12 months postoperatively, and at the final follow-up. Radiographically, we measured the femoral-tibial angle and mechanical axis deviation preoperatively and at the final follow-up. RESULTS: All clinical outcomes gradually improved in both groups from the postoperative period to the final follow-up. At the final follow-up, all clinical outcomes were slightly better in the UKA group than in the HTO group; however, differences were not statistically significant. CONCLUSIONS: HTO is comparable to UKA in terms of clinical outcomes. Thus, the results of this study suggest that HTO might be a good alternative treatment to UKA for medial unicompartmental arthritis accompanied by kissing lesions in relatively young patients.

BACKGROUND: The purpose of this study was to compare the clinical and radiological results of 2 different tibial fixations performed using bioabsorbable screws with added hydroxyapatite (HA) and pure poly-L-lactic acid (PLLA) screws in anterior cruciate ligament (ACL) reconstruction. METHODS: A total of 394 patients who underwent arthroscopic ACL reconstruction between March 2009 and June 2012 were retrospectively reviewed. Of those, 172 patients who took the radiological and clinical evaluations at more than 2 years after surgery were enrolled and divided into 2 groups: PLLA group (n = 86) and PLLA-HA group (n = 86). Both groups were assessed by means of the Lysholm score, International Knee Documentation Committee (IKDC) subjective knee score, and Tegner activity score. Stability was evaluated using the KT-2000 arthrometer. Magnetic resonance imaging was performed to evaluate tibial tunnel widening, screw resorption, osteoingeration, and foreign body reactions. RESULTS: The PLLA-HA group showed significant reduction in the extent of tibial tunnel widening and foreign body reactions and significant increase in screw resorption compared to the pure PLLA group (p < 0.001 for both). In contrast, postoperative Lysholm score, Tegner activity score, IKDC score, and side-to-side difference on the KT-2000 arthrometer showed no significant differences between groups (p = 0.478, p = 0.906, p = 0.362, and p = 0.078, respectively). The PLLA group showed more significant widening in the proximal tibial tunnel than the PLLA-HA group (p = 0.001). In the correlation analysis, proximal tibial tunnel widening revealed a positive correlation with knee laxity (r = 0.866) and a negative correlation with Lysholm score (r = −0.753) (p < 0.01 for both). CONCLUSIONS: The HA added PLLA screws would be advantageous for tibial graft fixation by reducing tibial tunnel widening, improving osteointegration, and lowering foreign body reactions. Even though no clinically significant differences were noted between the pure PLLA group and PLLA-HA group, widening of the proximal area of the tibial tunnel showed a tendency to increase knee laxity measured using the KT-2000 arthrometer.

BACKGROUND: We aimed to examine the factors that influence synovialization of the grafted tendon after double-bundle anterior cruciate ligament (ACL) reconstruction based on second-look arthroscopic findings. METHODS: Out of 205 knees that were treated between August 2008 and May 2016 with double-bundle ACL reconstruction using bio-absorbable cross-pins and Endobuttons for femoral tunnel fixation, we enrolled 65 knees (64 patients) that underwent second-look arthroscopy with hardware removal at 1 year postoperatively. Measured clinical outcomes included the Lysholm score and Tegner activity score that were evaluated preoperatively and during the final follow-up. We analyzed the relationship between synovial coverage and patient age, length of the preserved remnant tissue on the tibial side, type of bundle (anteromedial or posterolateral), type of graft (autograft or allograft), and time from injury to surgery. RESULTS: The area of synovial coverage showed a significant statistical correlation with patient age and the length of the preserved remnant tissue on the tibial side. The average synovial coverage was significantly better for the anteromedial bundle than for the posterolateral bundle, better for the autograft than for the allograft reconstruction, and better when treated in the acute stage than in the chronic stage. However, synovialization of grafted tendon did not correlate to clinical outcomes. CONCLUSIONS: While we were able to identify several factors influencing synovialization of the grafted tendon after double-bundle ACL reconstruction, including patient age, length of preserved remnant tissue of the torn ACL, type of bundle, type of graft, and time from injury to surgery, we found no evidence that increased synovialization improves clinical outcomes at 1 year postoperatively.

PURPOSE: Anterior cruciate ligament (ACL) injury is one of the most common injuries that occur in the knee, and ACL reconstruction (ACLR) is commonly performed for preventing aggravation of degenerative changes and restoring of knee stability in young, athletic patients. This metaanalysis has a purpose of evaluating the clinical and arthrometrical outcomes of ACLR in a group of middle age patients (40 years and older) and comparing with patients under 40 years of age. METHODS: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, and SCOPUS electronic databases were searched for relevant articles comparing the outcomes of ACLR between younger and older than 40 years of age until December 2016. Data searching, extraction, analysis, and quality assessment were performed based on the Cochrane Collaboration guidelines. Clinical outcomes were evaluated and compared between groups. The results were presented as mean difference for continuous outcomes with 95% confidence intervals whereas risk ratio for binary outcomes. RESULTS: Seven studies were included in the meta-analysis. Based on International Knee Documentation Committee classification, side-to-side difference, Tegner activity score, Lysholm knee score, there were no significant clinical and mechanical differences between the groups. CONCLUSIONS: This meta-analysis confirmed that after ACLR, middle age (>40 years) and young age (<40 years) patients did not present with significant difference in clinical and arthrometric results.

The Journal of the Korean Orthopaedic Association 1994;29(7):1767-1775
Endoscopic anterior cruciate ligament reconstruction using central one-third of bone-patellar tendon-bone autografts were performed on 76 consecutive patients. 36 patients out of them were reviewed and evaluated with subjective and functional rating scales according to the Lysholm knee scoring system, physical examination and instrumented anterior laxity test. The average follow-up was 2 years and 1 month, ranging from 1 year and 6 months to 3 years and 8 months and the everage age at operation was 31 years old, ranging from 20 to 49 years old. At follow-up, the average Lysholm knee score was 87.2 compared to the average score of 49.5 prior to reconstruction. Physical examination and instrumented anterior laxity test showed that excellent anterior stability was regained in all patients but two. There were 4 cases of complication, a fibrous nodule anterior to reconstructed ACL, an effusion of knee, a thrombophlebits, and an inadequate placement of screw fixation with protrusion of bone peg out of tibial hole. In summary, endoscopic ACL reconstruction using central 1/3 of bone-patellar tendon-bone seems to be a good procedure, which leaves less operative scar, takes short operation time and gives a constant good result as far as the surgeon is familiar with the technique.

The treatment of acutely torn anterior cruciate ligament(A.C.L) remains a controversial subject. The purpose of this paper is to show the arthroscopic technique of A.C.L. primary repair with or without augmentation with semitendinosus tendon. Twenty-one patients with acute A.C.L. tear were treated with repair or augmented repair under arthroscopic control from April 1989 to August 1993. Five A.C.L. torn at femoral attachment with intact distal stump were treated with arthoscopic repair alone & 16 A.C.L. torn at substance near the femoral attachment with arthroscopic repair & augmentation with semitendinosus tendon. The patient population included of 16 males and 5 females with an average age 28.3 years. Fifteen patients injuried during sports activity. Postoperative results were evaluated by Lysholm knee score & Hospital for Special Surgery knee scale in average 26 months (range from 12 months to 64 months). All patients were rated as good or excellent result except one patient who had fair result. At follow-up study, testing with KT1000 arthrometer revealed 17 patients had less than 3mm of side to side difference. Second look arthroscopy was performed in 15 patients from 4 to 29 months after repair or augmented repair. Eleven out of these 15 A.C.L. were well healed with good tension 8r. revascularization of graft. Remaining 4 A.C.L. were healed with scar tissue. On the based of this study, arthroscopic repair or augmented repair is very effective treatment for acutely torn A.C.L. near the femoral attachment.

The significance of the posterior cruciate ligament (PCL) in the stability of the knee and the necessity for surgical repair of its tears are still controversial. The purpose of this study is to present the short term results of surgical repair and Kennedy LAD augmentation for 15 cases with PCL injury. In 14 patients (15 knees), the torn PCL was repaired with pullout suture technique and Kennedy LAD augmentation was done from june 1993 to june 1994. The follow-up period ranged from 12 months to 25 months (average, 18months). The main causes of injuries were traffic accidents in 12. Thirteen of the patients were men and one was a woman, ranging in age from 17 to 52 years(average, 35 years). 10 knees were acute injury and repaired at average 9 days after injury. There were 11 cases that had combined injuries(4 ACL injuries, 4 meniscus injuries, 3 MCL injuries etc). In eight knees, the tear was in mid substance area and in five it was near femoral attach site and in two it was near tibial attach site. Postoperative results were evaluated by roentgenographic evaluation of posterior sagging and Lysholm knee score. 11 knee were stable but 4 knees were unstable posteriorly during postoperative follow-up period. 3 chronic injuried knees were included in 4 posteriorly unstable knees. There are 7 combined knee injuries in 11 stable knees and no combined injuries in unstable knees and average Lysholm knee score was 89.7 in stable knees and 90 in unstable knees and there was no significant difference between two groups. On the based of this study, surgical repair with pollout suture technique and augmentation with Kennedy LAD in acute PCL injury is a one of the good method for preventing posterior sagging but more longer follow-up period and more cases must be needed to accept this method.
