RESUMEN
BACKGROUND: The purpose was to investigate survival of cartilage repair in the knee joint by osteochondral autograft transfer stratified by location of the lesion; patellofemoral joint (Nâ¯=â¯26) versus the medial or lateral femoral condyles (Nâ¯=â¯58). METHODS: For survival analyses, "failure" was defined as the event of a patient reporting a poor Lysholm score (below 65 points) or undergoing a knee replacement procedure. RESULTS: The survival distribution was not significantly different between the patellofemoral joint and the tibiofemoral joint groups. CONCLUSIONS: The current study suggest that similar long-term outcome can be expected after OAT procedures for the patellofemoral or tibiofemoral joint. LEVEL OF EVIDENCE: Therapeutic study, Level III.
RESUMEN
OBJECTIVE: To investigate survival of cartilage repair in the knee by microfracture (MFX; n = 119) or mosaicplasty osteochondral autograft transfer (OAT; n = 84). DESIGN: For survival analyses, "failure" was defined as the event of a patient reporting a Lysholm score <65 or undergoing an ipsilateral knee replacement. The Kaplan-Meier method was used for construction of a survival functions plot for the event "failure." Log rank (Mantel-Cox) test was used for comparison of survival distributions in the 2 groups. RESULTS: The long-term failure rate (62% overall) was significantly higher in the MFX group (66%) compared with the OAT group (51%, P = 0.01). Furthermore, the mean time to failure was significantly shorter (P < 0.001) in the MFX group, 4.0 years (SD 4.1) compared with the OAT group, 8.4 years (SD 4.8). In the OAT group, the survival rate stayed higher than 80% for the first 7 years, and higher than 60% for 15 years, while the survival rate dropped to less than 80% within 12 months, and to less than 60% within 3 years in the MFX group, log rank (Mantel-Cox) 20.295 (P < 0.001). The same pattern was found in a subgroup of patients (n = 134) of same age (<51 years) and size of treated lesion (<500 mm2), log rank (Mantel-Cox) 10.738 (P = 0.001). The nonfailures (48%) were followed for median 15 yeas (1-18 years). CONCLUSIONS: MFX articular cartilage repairs failed more often and earlier than the OAT repairs, both in the whole cohort and in a subgroup of patients matched for age and size of treated lesion, indicating that the OAT repair is the more durable. LEVEL OF EVIDENCE: Therapeutic study, Level III.

PURPOSE: Some studies suggest a common degenerative path might contribute to a range of shoulder diseases involving subacromial pain syndrome and full-thickness rotator cuff tears. One could therefore theorize arthroscopic subacromial decompression and rotator cuff repair as interventions at different stages of a degenerative shoulder disease. Few studies have compared long-term outcomes after these two procedures. METHOD: Matched case-controls undergoing arthroscopic rotator cuff repair combined with subacromial decompression (Nâ¯=â¯180) or subacromial decompression only (Nâ¯=â¯180) were evaluated pre- and 7.5 years postoperatively using QuickDASH score, VAS of function, VAS of pain and VAS of satisfaction. New surgery and complications were recorded. Baseline characteristics were related to outcomes to investigate predictors of good/poor outcome. RESULTS: A general improvement from baseline was seen - from 51 to 14 (QuickDASH) in the combined group and from 53 to 16 in the decompression only group. No differences in outcomes were seen between groups (n.s.). Age above 55 at surgery predicted better VAS of function (Pâ¯=â¯.04) while acute onset of symptoms predicted better QuickDASH in the combined group (Pâ¯=â¯0.03). None in the decompression group had undergone later rotator cuff repair. CONCLUSION: Major improvements in pain/function were seen at mid- to long-term after isolated arthroscopic subacromial decompression and combined decompression/rotator cuff repair. Several patient-specific factors predicting worse outcomes were identified.
RESUMEN
PURPOSE: To identify early determinants of clinical outcome after knee cartilage repair. METHODS: 205 patients were evaluated before surgery and at median 14-years follow-up. RESULTS: Baseline factors predicting a good outcome were: single lesion; normal appearing cartilage surrounding the lesion; high baseline Lysholm score; short duration of symptoms; non-involvement of the patella-femoral joint; young age; and small defect. Factors predicting a poor outcome were: multiple lesions; low baseline Lysholm score; degenerative cartilage surrounding the lesion; long symptom duration; meniscal lesion; and large defect. CONCLUSIONS: The choice of surgical method seem to be less important than other patients-specific predictors. LEVEL OF EVIDENCE: Case series, Level IV.
RESUMEN
BACKGROUND: Few comparative randomized long-term studies on microfracture versus mosaicplasty have been published, and only 2 studies reported a follow-up of 10 years. Hypothesis/Purpose: The purpose was to compare the clinical outcome of microfracture versus mosaicplasty/osteochondral autograft transfer in symptomatic cartilage lesions. The null hypothesis was that the outcome was not statistically different at any point of time. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Forty patients with articular cartilage defects were randomized to undergo cartilage repair by either microfracture (n = 20) or mosaicplasty (n = 20). Inclusion criteria were as follows: age 18 to 50 years at the time of surgery, 1 or 2 symptomatic focal full-thickness articular chondral defects on the femoral condyles or trochlea, and size 2 to 6 cm2. The main outcome variable was the Lysholm knee score recorded before the surgery and at 12 months, median 5 years, median 10 years, and minimum 15 years after the surgery. RESULTS: Forty patients were included in the study (28 men, 12 women; median age, 32 years; range, 18-48 years). Defects with a median size of 3.5 cm2 (range, 2-5 cm2) were treated. A significant increase in the Lysholm score was seen for all subjects- from a mean 53 (SD, 16) at baseline to 69 (SD, 21) at the minimum 15-year follow-up ( P = .001). The mean Lysholm score was significantly higher in the mosaicplasty group than the microfracture group at 12 months, median 5 years, median 10 years, and minimum 15 years: 77 (SD, 17) versus 61 (SD, 22), respectively ( P = .01), at the last follow-up. At all follow-up time points, the difference in mean Lysholm score was clinically significant (>10 points). CONCLUSION: At short, medium, and long term (minimum 15 years), mosaicplasty results in a better, clinically relevant outcome than microfracture in articular cartilage defects (2-5 cm2) of the distal femur of the knee in patients aged 18 to 50 years.

BACKGROUND: The purpose of this study was to evaluate the outcome after cartilage repair surgery in focal defects of the knee by microfracture versus mosaicplasty. METHODS: A cohort of 102 patients undergoing microfracture (n=52) or mosaicplasty (n=50) of a single articular cartilage defect in the medial femoral condyle of ≤50mm2 was evaluated by Lysholm score before surgery, at six months, 12months, five years, 10years, and 15-18years after surgery. RESULTS: Median age of patients at the time of surgery was 36years (range 16-58) and median follow-up time was 16years (range 14-18). Defects were treated with a median size of three square centimetres (range one to five). A significant increase was seen in the Lysholm score from mean 48 (SD 16) at baseline to 66 (SD 23; P<0.001) at the 15-18year follow-up. The Lysholm score was higher in the mosaicplasty group at six months, 12months, five years and 10years (P<0.05 for all comparisons). These differences were clinically significant at all points (>10 points). However, at the final follow-up, the difference (eight points) did not reach statistical significance. CONCLUSIONS: In the short-term, medium-term and long-term (10years), mosaicplasty in a single cartilage defect size one to five square centimetres of the femoral condyle resulted in clinically relevant better outcome than microfracture. However, at 15-18years after the surgery such a difference could not be found. In the six month to 10-15year (after surgery) perspective, the mosaicplasty procedure offered a better outcome in this type of lesion. LEVEL OF EVIDENCE: Level III.

PURPOSE: To evaluate mid- to long-term results after arthroscopic rotator cuff repair and to explore possible predictors of inferior outcome. METHODS: Patients treated for full-thickness supraspinatus and/or infraspinatus tears from 2004 to 2008, using a uniform single-row arthroscopic technique, were included in the study. Pre- and post-operative QuickDASH were used as the primary outcome measure, and VAS of pain, function and satisfaction were also collected. An additional questionnaire explored demographic and preoperative factors like onset and duration of symptoms, preoperative treatment and smoking habits. RESULTS: One hundred and forty-seven patients (82 %) were available at 6-9 years after surgery. All outcomes improved significantly from the preoperative values. A total of 8 % of patients had undergone additional surgery to the same shoulder during the follow-up period. Long-standing symptoms (>12 months) (P < 0.01), non-acute onset of symptoms (P < 0.01) and preoperative use of NSAIDs (P = 0.01) were correlated with inferior outcome at follow-up. No other factors investigated (i.e. gender, age, smoking and steroid injections) were found to affect the primary outcome (QuickDASH). CONCLUSION: The current study is one of few reports of mid- to long-term outcomes after arthroscopic single-row repair of full-thickness rotator cuff tears. Global improvement in symptoms and function was found between the preoperative and the 6-9 years evaluation, and the technique therefore seems like a viable approach for treating tears of the supra- and the infraspinatus tendon. Several predictors of inferior long-term outcome after rotator cuff repair were, however, identified: preoperative use of NSAIDs, long-standing symptoms before surgery and non-acute onset of shoulder symptoms. In light of the current findings, accurate diagnosis and prompt treatment seem important in optimizing outcomes after rotator cuff surgery. LEVEL OF EVIDENCE: IV.

PURPOSE: To compare the outcome of 2 arthroscopic techniques for treating recalcitrant lateral epicondylitis. METHODS: The study included patients undergoing arthroscopic treatment of lateral epicondylitis during 2 different time periods: April 2005 to October 2007 (tenotomy) and May 2009 to June 2010 (debridement). By using a patient-administered form, baseline information including QuickDASH (disabilities of the arm, shoulder and hand) score (primary outcome), visual analog scale (VAS) of pain, and VAS of function was recorded prospectively. To have the same follow-up period of minimum 4 years in the 2 groups, the follow-up was conducted at 2 different points of time. RESULTS: Of a total of 326 patients fulfilling the requirements for inclusion in the study, 283 patients (87%) were followed up (144 male and 139 female, median age 46 [21 to 65] years), 204 (87%) in the tenotomy group and 79 (88%) in the debridement group. In both groups, a significant improvement in the QuickDASH was found at the follow-up compared with baseline: from 60 to 12 in the debridement group (P < .001) and from 59 to 13 in the tenotomy group (P < .001). No statistically significant difference was found in baseline or follow-up QuickDASH, VAS of pain, VAS of function, or failure (reoperation) rate between the 2 groups. The mean length of sick leave was 2 weeks shorter in the debridement only group (P = .007). CONCLUSIONS: Both arthroscopic methods lead to a significant improvement of pain and function, and no statistically significant difference was found in any outcome parameters between the 2 techniques at this minimum 4-year evaluation. The results indicate that tenotomy of the extensor carpi radialis brevis may be an unnecessary step in the arthroscopic treatment of lateral epicondylitis Debridement only is a potentially less costly procedure, and the current finding of a mean 2 weeks shorter sick leave in the debridement only group proposes a substantial cost saving in a societal perspective. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

PURPOSE: The purpose of the present study was to evaluate the outcome at a minimum of 7 years following meniscal repair using the RapidLoc (suture anchor) system. It was hypothesized that most patients would have an intact meniscus, as has been reported in several short- and medium-term studies. METHODS: In the time period from 2002 to 2007, all patients with a vertical longitudinal tear of the meniscus that was judged to be repairable were treated with rasping of the tear area and nearby parameniscal synovium and fixation of the torn part with the use of RapidLoc implants. Using a surgeon-administered form, baseline information about the arthroscopic findings and procedures performed was recorded (at the time of surgery). A median 10-year (range 7-12 years) follow-up was conducted in 2014-2015, and surgical procedures to the knee following the (index) meniscal repair were registered. Treatment failure was defined as a new surgical procedure to the same meniscus. RESULTS: At the time of follow-up, 39 out of 82 patients (48 %) had undergone further surgery to the repaired meniscus (failures). Nine of these occurred within the first 6 months after surgery, 21 within the first 12 months and 26 within the first 24 months. Thus, the failure rate was 11 % at 6 months, 23 % at 12 months and 28 % at 2 years. One-third (N = 13) of the failures occurred 2 years or later after the (index) meniscal repair. CONCLUSIONS: Long-term results of meniscal repair using the RapidLoc implants were found to be poor with a high failure rate. In a large proportion of the cases, re-rupture appeared several years after the index surgery, and a commonly used follow-up period of 2 years would therefore fail to detect them. In the day-by-day clinical work, of interest to orthopaedic surgeons is that meniscal repair using an all-inside technique similar to the one used by the authors may not solve the problem in the long run.

PURPOSE: To evaluate the long-term clinical outcome after microfracture treatment of focal chondral defects of the knee and to investigate possible early determinants of the outcome. METHODS: A prospective cohort of 110 patients, treated with microfracture, was evaluated at a median of 12 years (range 10-14) by Lysholm score, VAS of knee function and VAS of knee pain. Pre- and perioperative information was collected, and additional surgery to the same knee during the follow-up period was recorded. Analysis of variance and paired t test were used for comparison of the long-term data to results from the baseline examination and a former 5-year (midterm) follow-up evaluation. RESULTS: Forty-three patients needed additional surgery to the knee including seven knee replacements. Fifty had a poor long-term outcome-defined as a knee replacement surgery or Lysholm score below 64. A poor result was more common in subgroups with mild degenerative changes in the cartilage surrounding the treated defect, concurrent partial meniscectomy, poor baseline Lysholm score or long-standing knee symptoms. The Lysholm score, function VAS and pain VAS all significantly improved from the baseline values to the mean scores of 65 (SD 24), 65 (SD 24) and 31 (SD 24), respectively, at the long-term evaluation. The long-term scores did not differ significantly from the midterm scores. CONCLUSIONS: The outcome scores improved significantly from baseline to the long-term evaluation and were not different from the midterm outcome. Still, a normal knee function was generally not achieved, and many patients had further surgery. The results call for more research and, at present, caution in recommending microfracture in articular cartilage defects, especially in subgroups with worse prognosis. LEVEL OF EVIDENCE: Case series, Level IV.

PURPOSE: The aim of this study was to evaluate the medium-term (5-9 years) and long-term (10-14 years) outcomes of mosaicplasty in the knee and identify possible risk factors for poor outcome. METHODS: We included patients 60 years or younger with symptomatic focal full-thickness chondral lesions. Seventy-three patients (87%) with median age of 34 years were available for analyses. Clinical outcome was evaluated by Lysholm score and VAS of pain. RESULTS: Both the mean Lysholm score and mean VAS pain score improved significantly from baseline, 49 (SD 17) and 58 (SD 23), respectively, to both the mid-term follow-up, 72 (SD18, p<0.001) and 27 (SD 20, p<0.001), respectively, and the long-term follow-up, 72 (SD 21, p<0.001) and 33 (SD 23, p<0.001), respectively. A poor outcome at the long-term follow-up - defined as a Lysholm score of 64 or less or having had a knee replacement - was found in 40%. A poor outcome was more frequent in patients 40 years or older (59%), in women (61%) and in defects with an area of 3 cm(2) or more (57%). Conversely, in a subgroup of male individuals younger than 40 years with defect size less than 3 cm(2) the failure rate was 12.5% and the mean Lysholm score was 82 (SD 16). CONCLUSION: We conclude that the long-term clinical outcome after mosaicplasty varies greatly depending on age, gender and the size of the lesion. LEVEL OF EVIDENCE: IV-Retrospective Case Series.

PURPOSE: The purpose of this study was to compare the outcome of arthroscopic and open tendon release in tennis elbow (TE). METHODS: We compared the outcome of patients treated by an open tendon release in the period from 2002 to 2005 (n = 80) with that of patients treated by an arthroscopic release of the extensor carpi radialis brevis in the period from 2005 to 2008 (n = 225). In both groups the inclusion criteria were symptomatic TE refractory to conservative care for a minimum of 6 months and a clinical follow-up of at least 3 years. The diagnosis was based on a typical history and positive clinical findings. Patients with previous surgery in the elbow, chondral or osteochondral lesions, osteoarthritis, or free bodies were excluded. To have a similar follow-up period in the 2 groups (median, 4 years), the follow-up was conducted at 2 different time points. RESULTS: The groups did not differ significantly with regard to the age of the patients, distribution of gender, distribution of affected side, duration of symptoms, or baseline score on the short version of Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH). We did not observe any major complications. The failure rate was not significantly different between the 2 groups. At follow-up, the mean QuickDASH score was statistically significantly better (P = .004) in the arthroscopic group (11.6 points; SD, 15.6 points) compared with that in the open group (17.8 points; SD, 19.4 points). The percentage of elbows with an excellent outcome at follow-up (QuickDASH score <20 points) was significantly higher in the arthroscopic group (78%) than in the open group (67%) (P = .04). CONCLUSIONS: Both a traditional open approach and the newer arthroscopic method provide an effective treatment of recalcitrant TE without major complications. The arthroscopic method offers a small, but not insignificant, improvement in the outcome as evaluated by the QuickDASH score. LEVEL OF EVIDENCE: Level III, therapeutic case-control study.

PURPOSE: The objectives of this study were to evaluate the results in the outpatient treatment of recalcitrant lateral epicondylitis with release of the common extensor origin according to Hohmann and to determine any prognostic factors. METHODS: Eighty tennis elbows in 77 patients with a characteristic history of activity-related pain at the lateral epicondyle interfering with the activities of daily living refractory to conservative care for at least 6 months and a confirmatory physical examination were included. Clinical outcome was evaluated using the QuickDASH score system. Data were collected before the operation and at the medians of 18 months (range 6-36 months; short term) and 4 years (range 3-6 years; medium term) postoperatively. RESULTS: The mean QuickDASH was improved both at the short- and the medium-term follow-ups and did not change significantly between the follow-ups. At the final follow-up, the QuickDASH was improved in 78 out of 80 elbows and 81% was rated as excellent or good (QuickDASH<40 points). We found a weak correlation between residual symptoms (a high QuickDASH score) at the final follow-up and high level of baseline symptoms (r=0.388), acute occurrence of symptoms (r=0.362), long duration of symptoms (r=0.276), female gender (r=0.269) and young age (r=0.203), whereas occurrence in dominant arm, a work-related cause or strenuous work did not correlate significantly with the outcome. CONCLUSION: Open lateral extensor release performed as outpatient surgery results in improved clinical outcome at both short- and medium-term follow-ups with few complications. High baseline disability, sudden occurrence of symptoms, long duration of symptoms, female gender and young age were found to be weak predictors of poor outcome. LEVEL OF EVIDENCE: Case series, Level IV.

We evaluated short- and medium-term results of the treatment of articular cartilage defects of the knee with autogenous cylindrical osteochondral grafts (mosaicplasty) in 69 patients (median age 33 years) with symptomatic articular cartilage defects. Data of Lysholm score and visual analogue scale (VAS) of pain (0=no pain; 100=worst possible pain) were collected before the surgery, at 12 months postoperatively and 5 to 9 (median 7) years after the surgery. At the last follow-up the patients were also asked to state their degree of satisfaction with the outcome on a VAS (0=not at all satisfied; 100=completely satisfied), and to answer if they would have undergone the surgery again if necessary (yes or no). The mean Lysholm score and VAS of pain improved from 48 and 62, respectively, at the time of surgery to 81 and 24, respectively, at the 12-months follow-up (p<0.001 for both comparisons). From 12 months postoperatively, the Lysholm score and VAS of pain deteriorated to 68 and 32, respectively at the 5- to 9-year follow-up (p<0.001 and p=0.018, respectively). The mean degree of satisfaction with the outcome was 70 (SD 28), and 61 patients (88%) stated that they would have undergone the surgery again. In conclusion, the mosaicplasty leads to improvement of symptoms and function at short- and medium-term follow-up. A deterioration of the results is observed from 12 months postoperatively to 5-9 years postoperatively.

We compared the results of microfracture in single versus multiple symptomatic articular cartilage defects in the knee in 110 patients with a median age of 38 years (range 15-60). Cases of reoperation of the cartilage defect were classified as failures. Clinical outcome in non-failures was evaluated by the Lysholm score and grading of knee pain and function of the knee by the use of patient-administered visual analog scales (VAS; 0-100). Data were prospectively collected before the operation and at the 2- to 9-year follow-up. The single lesion or the largest of multiple lesions were located on the medial femoral condyle (n = 62), trochlea (n = 18), lateral tibia (n = 11), patella (n = 10) or lateral femoral condyle (n = 9). We treated one (n = 76), two (n = 27) or three (n = 7) lesions with a median total area of 4 cm(2) (range 1-15). A total of 24 failures (22%) were registered-18% in the single-defect subgroup and 29% in the multiple-defects subgroup. In the remaining group of patients (n = 86), the mean Lysholm score, mean pain-score (0 = no pain; 100 = worst possible pain) and mean function-score (0 = useless; 100 = full function) improved from 51, 52 and 41, respectively, to 71 (P < 0.001), 30 (P < 0.001) and 69 (P < 0.001) at the follow-up. The pain-score was significant lower (P = 0.042), and the function-score significantly higher (P = 0.001) in the group of patients with a single lesion compared to the group with 2 or 3 lesions. The Lysholm score did not differ significantly between the two subgroups (P = 0.06).

BACKGROUND: Frozen shoulder is a debilitating, long-lasting condition. At Bergen Surgical Hospital we have performed arthroscopic capsular release since 2003 in patients where conservative treatment has failed. The procedure is done as day surgery. The purpose of this study was to evaluate our results. PATIENTS AND METHODS: From June 2003 until October 2005 arthroscopic capsular and ligament release was performed in 66 patients (70 shoulders) with primary frozen shoulder. Oxford shoulder score and range of motion were recorded prospectively. Follow-up was done during autumn 2005 and included subjective evaluation of symptoms, function, satisfaction with the result of the procedure, Oxford shoulder score and clinical examination. RESULTS: 62 out of 66 patients would agree to have the same procedure done again. Degree of satisfaction with the result of the procedure (0 = worst, 10 = best) was 8.6 +/- 1.8 (SD) on average. Ability to work, physical activity and quality of night's sleep improved significantly (p < 0.001). Oxford shoulder score (12 = best, 60 = worst) decreased significantly from 41.0 +/- 7.5 (SD) to 18.4 +/- 7.3 (SD) (p < 0.001). External rotation, abduction and flexion increased significantly (p < 0.001). INTERPRETATION: The results from treatment of frozen shoulder with arthroscopic capsular release are good and suggest that the the condition shoulder is shortened. The procedure may be done safely as day surgery. We feel that more patients may benefit from the procedure.
